The Gemini PDA is a highly versatile device, and part of the versatility that made it so incredibly popular with Indiegogo backers was its ability to run different versions of the Linux operating system.  Linux is highly useful for many IT Pros and developers but installing it is not a process for the faint of heart.  If you feel brave enough and are confident you know what you’re doing then here are instructions on how you can install Debian Linux on your Gemini.

IMPORTANT: Please follow these instructions precisely, as incorrectly flashing your Gemini PDA can render it unusable.


There are a few things you’ll need to install Debian Linux on your Gemini and you’ll want to keep everything organised.  Make a folder on your PC. We will put all files here, so give it a recognizable name (GeminiPDA, for instance).

Download the following items to the folder you have created

Unzip the Android Firmware and Debian Linux Firmware (.zip) files by opening them and clicking the Extract Files button on the ribbon that appears in File Explorer.

Step-by-step Installation Guide

  • Install FlashTool Drivers: Open its folder, then open the “Install” sub-folder, and run the install.bat file

  • Open FlashTool: Open its folder, then open the flash_tool sub-folder, and run the flash_tool.exe file

  • If this is the first time running the FlashTool, it will give a warning about about a missing scatter file. You can dismiss this to continue.
  • You’ll now see five tabs next to an image reading MT6797. The tabs are called Welcome, Format, Download, Readback and Memory Test.
  • Go to the ‘Readback‘ tab, you’ll see four buttons reading Add, Remove, Read Back and Stop. click the ‘Add‘ button.  A line will appear in the open field below.
  • Click the ‘Read Back‘ button, connect your device to your computer using USB-C cable and (re)start it.  The NVRAM backup will then be saved to the FlashTool folder.

  • Click the ‘Download’ tab
  • You’ll now see Download/Stop buttons and below that, three rows. Click ‘Choose’ at the end of the ‘Scatter-loading File’ row

  • Open the ‘Gemini_Debian_TP’ folder and open the ‘Gemini_Debian_TP_Scatter’ text file
  • (Optional: TWRP. Only flash this is you want to use custom ROMs or have an easy way to backup and restore your complete device.)
    At ‘recovery’ location path, click and select TWRP’s recovery
  • (Optional: root access. This will allow read/write access to /system. If you do not know what root access is, or why you would need it, do not flash it.)
    At ‘boot’ location path, click and select rooted boot-verified.img
  • Below the three lines, there’s a selection box reading ‘Download Only’. Click on the box. On the drop-down menu, select ‘Firmware Upgrade’ instead of ‘Download Only’
  • Click the ‘Download’-button at the top of the tab
  • Make sure your Gemini is turned off and then connect it to your PC with USB-C cable, you will hear the “da-donk” sound when the connection has been successfully made
  • The selected firmware items will now download to your device. Wait until FlashTool is finished and dismiss the prompt when it’s finished

You can now boot your Gemini into Android, Linux (and optionally, TWRP). Booting into each of these requires a separate operation, clarified below.

Android: by holding down the ESC key for a few seconds, until the device vibrates
TWRP: hold down ESC until after vibrate and only release 1-2 seconds after screen turns on
Linux: hold down silver side button + ESC until 1-2 seconds after screen turns on

If you want to flash LineageOS, transfer the “lineage-14.1-[build date]”-file onto your Gemini PDA and boot into TWRP, as specified above. Once there, click ‘Install’, select the mentioned .zip-file and swipe to install. Reboot after it finishes.

    Can I make a phone call / SMS on the debian install, even if i completely flash the android?(is that even allowed?)

    I just found this wonderful piece of hardware and I’d prefer to use just linux on it.

    • peepuk peepuk

      The community has to come up with solutions for phone calls, SMS ,4G and MALI GPU; that will take some time.

      The reason is that hardware manufactures usually don’t like to support open source drivers for their products, especially for phone related stuff. Phones are for big companies much more interesting (financially) if they can spy on you.

      The first solutions will probably all use the current android-kernel and use a compatibility wrapper for the hardware drivers.

      Luckily Planet Computers are as open as they can be (boot loader is open source).

  2. Very nice guide.
    The booting process detailed in the guide only works for the very first Linux image. Since then it has been changed to the following:

    Android-only firmware
    – Press Esc (On) for a few seconds to turn ON the unit and boot into Android
    – Press Esc (On) and side button and keep pressed both buttons until the screen turns ON to boot in recovery mode. At this stage the recovery mode is disabled and you will see a droid image with a red triangle and a “No command” text.

    Dual boot Android-Linux firmware
    – Press Esc (On) for a few seconds to turn ON the unit and boot into Android
    – Press Esc (On) and side button at the same time until the screen turns ON to boot into Linux
    – Press Esc (On) and keep pressing the button until the screen turns ON to boot in recovery mode. At this stage the recovery mode is disabled and you will see a droid image with a red triangle and a “No command” text.

    • Please find a more precise version of the booting options here:

      Android-only firmware

      – Press Esc (On) for around one second to turn ON the unit and boot into Android.
      – Press Esc (On) for around one second to turn ON the unit and at the same time press and hold the side button until the screen turns ON to boot in recovery mode. At this stage the recovery mode is disabled and you will see a droid image with a red triangle and a “No command” text.

      Dual boot Android-Linux firmware

      – Press Esc (On) for around one second to turn ON the unit and boot into Android. You should release the Esc (On) button before the screen turns ON, otherwise the unit will boot into recovery mode (see below).
      – Press Esc (On) for around one second to turn ON the unit and at the same time press and hold the side button until the screen turns ON to boot into Linux. You should release the Esc (On) button before the screen turns ON, but you must keep the side button pressed until you see the turning ON. When the screen turns ON you can release the side button, and the unit will boot into Linux.
      – Press Esc (On) and keep pressing the button until the screen turns ON to boot in recovery mode. At this stage the recovery mode is disabled and you will see a droid image with a red triangle and a “No command” text.

    Can the install be performed using linux tools? OpenOCD or JTAG spring to mind.

    Don’t have any Windows devices in this household.

    NVRAM backup:

    “•If this is the first time running the FlashTool, it will give a warning about about a missing scatter file. You can dismiss this to continue.”

    In my case, if I don’t specify the scatter file, I get an alert “Please load a scatter file before execution” when pressing “Read Back” button. The read back process can’t be initiated. Only if I load a scatter file prior the read back, I can complete the backup. Is the assumption that you don’t need the scatter file correct?

    • Space Space

      Same situation here. Flash tool is not recognizing my Gemini, can’t back up the NVRAM. Keeps asking to load the scatter file. Please help!

      • Humpty Humpty

        Did either of you guys get this working? I’m facing the exact same issue.

        • Andy Pugh Andy Pugh

          Have you actually loaded a scatter file in to the flashing tool? There is one in the firmware pack, I believe, and an online tool to create custom ones if you want different partition sizes.

          • Humpty Humpty

            I was working on the assumption that I could ignore that part as per above “If this is the first time running the FlashTool, it will give a warning about about a missing scatter file. You can dismiss this to continue.”

            I’ve since loaded a scatter file that I am lead to believe is the default layout and have a copy of the NVRAM. I’ve no way to validate this is correct without flashing it back I guess?

          • I suspect that you are right about the NVRAM. But don’t know for sure. I am no expert, I am just someone who managed to flash a Gemini once.

  5. I have been trying to unzip the Linux firmware file in Windows and Linux and the unzip process fails on both platforms. Windows returns error 0x80004005. Linux returns a generic error simply saying that the unzip failed. I prefer to use the Windows option. Any help would be much appreciated.

  6. Benjamin Trister Benjamin Trister

    As it turns out, the Linux firmware file could not be unzipped with the standard Windows extract method. I had to download another app, 9 zip, and it was able to extract the files.

    I do have another issue, though. I am able to start Linux now, but it presents a log-in screen with only one user named Gemini. I do not have the password, nor do I see a way to add another user. Does anyone know the required password or a way around it? Thanks.

    • Andy Pugh Andy Pugh

      The password appears to be “planet”

      • Andy Pugh Andy Pugh

        I was wrong, ignore the above. I have no idea what made me think that I had used that password.

  7. try password “GEMINI”

  8. ArchiMark ArchiMark

    Installed Debian and it runs but have a few issues.

    1. Mouse

    Mouse did not work when plugged into the Gemini usb hub. Had to buy a usb to usb-c adaptor and plug mousmouse into Gemini without the hub. So, can’t use other usb devices or Ethernet cable.

    Anyone use mouse with the hub?

    2. Keyboard Layout

    Can’t type the characters printed on the front edge of keyboard. I’m using US keyboard.

    Any way to type all the characters?

    3. Terminal

    Get error message when trying to use UXterm.

    Xterm runs, but text is microscopic. Need magnifying glass to read text. Any way to you enlarge text?

    Thanks for any and all help.

    • Adam Adam

      Were you able to type `sudo nano /etc/passwd`? My keyboard can’t produce the `/` symbol and I can’t find a way to connect an external keyboard to the device–it doesn’t seem to be able to detect Bluetooth yet.

      • Andy Pugh Andy Pugh

        I connected via SSH to run through the setup instructions. If I recall correctly ssh is already installed and working, so if you connect to your network you can ssh in from another machine. I used my Mac (ssh is part of the OS, the same is true with Linux). I think you need PuTTY to use SSH with Windows.

        • Adam Adam

          So I asked how to do this on AskUbuntu, they said I need to know the device’s IP address. I did my best to determine the IP address of this device (or is it the IP address of the network all my devices are on?). I went to the Connman System Tray and looked at the Details tab where I found an IP address, so punched in `ssh **that address**` into the terminal on my desktop, but got the error `ssh: connect to host port 22: No route to host`. After trying to chase down what was causing that error I tried a few things but nothing worked. Am I on the right path here?

          • Adam Adam

            I should note that I typed `ifconfig` into the terminal on the phone and it gave an error that it didn’t recognize the command.

          • I think that I logged in to my WiFi modem/router ( in a web browser on a PC) and looked at the “connected devices” list.
            this command, on the Gemini,
            ip addr show
            might help, as an alternative.

  9. gidds gidds

    Help!! Any tips on how to get this to work?

    Short version: When I try to back up the NVRAM, the Flashing Tool stops with an error 3 seconds after connecting the Gemini. (Or, if the Gemini is already booted, it just sits there doing nothing until I hit Stop.)

    Long version: This is on a MacBook Pro booted into Ubuntu 18.04 LTS from a USB stick. (I don’t have access to anything running Windows or Linux natively.) I downloaded the Flashing Tool from (I also downloaded firmware, but I don’t think it’s got as far as needing that yet.)

    I’m using the USB-A to USB-C cable supplied with the Gemini. (I tried it plugged into either side of the Gemini; the left-hand side looks more promising.)

    The Gemini is off and disconnected. I started the Flashing Tool from a Terminal window, so I can see its console output. I’ve selected the desired scatter file in the Download tab. I switch to the Read Back tab, click the Add button, see the row appear in the table, click on Read Back, connect the Gemini, and hold down its Esc button. Three seconds after connecting (long before the Gemini has started to boot), the Flash Tool shows an error dialog (“ERROR : STATUS_ERR (-103676387) , MSP ERROE CODE : 0x00. [HINT]:”), and the following appears on its console:


    Connecting to BROM…
    Scanning USB port…
    Search usb, timeout set as 3600000 ms



    vid is 0e8d

    device vid = 0e8d

    pid is 2000

    device pid = 2000

    com portName is: /dev/ttyACM0

    Total wait time = -1526667349.000000
    USB port is obtained. path name(/dev/ttyACM0), port name(/dev/ttyACM0)
    USB port detected: /dev/ttyACM0
    Connect BROM failed: STATUS_ERR
    BROM Exception! ( ERROR : STATUS_ERR (-1073676287) , MSP ERROE CODE : 0x00.



    Alternatively, if I start the Gemini and THEN connect it, the Flash Tool just sits there doing nothing. In that case, its console shows:


    Connecting to BROM…
    Scanning USB port…
    Search usb, timeout set as 3600000 ms







    (I suspect the backlight/gmux_backlight is irrelevant, related to the Mac’s own display.)

    Googling parts of the error message hasn’t shown me anything useful.

    If it matters, once the Gemini has booted it seems to show as a drive on the Mac, so I’m guessing the cable works.

    Any ideas, please? I’ve spent hours over several days getting to this point already. (Had to buy a USB stick to install Ubuntu on. And today: how do you transfer a >4GB file from macOS to Linux, when the only filesystem both can read and write is FAT32 which is restricted to 4GB files? Answer: after spending ages reformatting sticks and cards, and trying to set up an SSH server on on machine, you give up and transfer the .zip file which is just under 4GB…)

    This was supposed to be easy!

    • ArchiMark ArchiMark

      Did you read this page?

      This is the dev team that is releasing the Debian images for Planet Computers.

      You’ll note in text near top of page, that the TP in DebianTP, stands for ‘Technical Preview’. ie, a work in progress. As Adam noted there, the next image file version released should be a lot more developed. So, little to none post-install tweaks needed.

      So, as of now, it is not supposed to be easy.

      I’d suggest you post this over at OESF forums in the Gemini Linux section, as Adam does visit and post there.

      In meantime, I’d also suggest you read the Flashing Guide page that is linked to on the DebianTP page.



    • grw grw

      You need to turn on the Gemini once you have pressed start in the flashing tool.

      • gidds gidds

        If by ‘start’ you mean the Read Back button, then that’s exactly what I did! As I said, I “…click on Read Back, connect the Gemini, and hold down its Esc button.”

    • Are you running the tool as root? That allowed me to backup the NVRAM, it just wouldnt when run as normal user.

  10. Steve Hayes Steve Hayes

    Is it best to use a PC with Linux, Windows or Mac OS when doing the Linux installation?

  11. gidds gidds

    The Flashing Tool is currently available only for Windows and Linux, so you can’t run it on macOS at all.  (That’s why I had to try with Ubuntu live on a USB stick, not having a copy of Windows.)

    Can anyone confirm whether the charging cable supplied with the Gemini does data too?  Is it possible to flash the Gemini using that cable, or was that my mistake?

    Also, can anyone who’s had any luck from a version of Linux mention which distro/version (and what sort of hardware)?

    • ArchiMark ArchiMark

      Yes, you can flash with the cable that comes with the Gemini.

      Just make sure you plug cable into the left side of Gemini when you flash. It doesn’t work on the other side.

    • Andy Pugh Andy Pugh

      I flashed mine using VMware fusion on my Mac.

      I then used the Mac for all the other config. Don’t be too disappointed with the initial install, things get a lot better when you install the updates. I worked through everything here once I had ssh-ed in from the Mac.
      I had to log in to my router to work out what IP address the Gemini had been given, and it didn’t connect to the WiFi until I found “connman” lurking in the “internet” part of the apps menu (bottom left hand corner of the screen. A stylus might help 🙂

  12. Shay Shay

    Thanks for the earlier comments. I flashed my Gemini using a Windows machine using the instructions above. Now I can see the ‘Powered by Linux’ screen followed by ‘Powered by Android’ screen. No matter what combinations I choose, following those above, I can’t seem to get Linux to boot. Frustrating.

  13. Shay Shay

    Ps. Can anyone provide a more detailed, blow-by-blow description of what’s being done that’s wrong? I seem to end up going to the Android screen or the Android screen with red triangle but not the Linux Debian screen.

  14. Shay Shay

    Pps. Can anyone provide a more detailed, blow-by-blow description of how to boot Linux.For example in the description above for booting up Linux it isn’t so clear, saying…

    “Press Esc (On) for around one second to turn ON the unit and at the same time press and hold the side button until the screen turns ON to boot into Linux. You should release the Esc (On) button before the screen turns ON, but you must keep the side button pressed until you see the turning ON.”

    In the last sentence – “but you must keep the side button pressed until you see the ???WHAT??? turning ON.”

    I am presuming that because I can see the penguin and ‘Powered by Linux’ but default to the Android OS that the machine is now a dual boot machine.

    Thanks again in advance.

  15. Let’s start from a situation where your Gemini is OFF.

    To start the unit, you will have to press Esc (On) for a little bit, like a second, otherwise if you press the button too quickly the unit will not start. After you press Esc (On) for a second, the unit will start booting. However, at this stage, the screen is still OFF (black). For a few seconds the unit will be quietly booting and do a lot of operations with the screen still OFF (black). After a few seconds the screen will turn ON and you will see the boot screen with the penguin.

    When the screen turns ON (so when from a completely black screen you see the boot logo with the penguin), the unit will check the status of the buttons. If at that time the Esc (On) is pressed, then it will boot into recovery mode. If instead the side button is pressed, which is what you want, then the unit will boot into Linux.

    The Esc (On) button has priority over the side button, so if both buttons are pressed when the screen turns ON, then the unit will boot into recovery mode, which is what I guess is happening to you.

    Did you manage to solve this issue? I’m running into the same error (tried multiple Linux distros, using current firmware, left usb-c port)

    • Shay Shay

      Not entirely no, installation then boot up of Linux is tough to get sorted.

  18. gidds gidds

    Which OS were you running under VMWare Fusion?

    (I don’t have Windows, and shelling out for VMWare Fusion *and* for Windows seems a bit steep just to run the Flashing Tool…)

  19. ottofaun ottofaun

    has anyone got an idea whether gidds’ problem was solved? Iam stuck with the same issue…

    • gidds gidds

      I (sort of) got this working.

      Important points (in my case): Use Debian 9.  (I never got it working from Ubuntu.)  Use the unofficial version of Debian 9 with non-free additions (else wifi won’t work).  Install the missing library that the Flash Tool complains about.  And power down the Gemini first; I didn’t need to boot it or anything, as the Flash Tool recognised it after connecting, while off.

      I posted all the details here:

      (Sorry if this is a dup post; thought I’d already replied but can’t see it.)

  20. max max

    Overall nice impression. But how can one get the config right to be able to type the “alternative”, say, Fn+o = “-” characters?

  21. ccarrieta ccarrieta

    need some help.. I am trying to follow directions but cant seem to get going. I downloaded all the required files.. First install the flash tool drivers then the flash tool, I unpacked the debian and android images. I start the Flash tool without the PDA connected to my PC. My first issue is that I don’t get a MT6797 image just a MediaTek, not sure if this is an issue.. I then go to Readback and then add a line. I start with the PDA turned off connect it with the PDA cable and then turn it on… I am not sure if a am doing something wrong I just don’t seem to be able to install debian, I only get an error please load a scatter file before execution…

    • Richard Roman Richard Roman

      I have this same issue. I’m not seeing any feedback on this yet.

    • You need a “scatter file” which appears to be a text file that says where on the Gemini storage device each file belongs. There should be one in the firmware download, or if you want different partition sizes to the default (I wanted a bigger Debian than Android partition) then you can make a custom one using the online tool:

  22. Adam Adam

    I followed these instructions and, in the middle of the download, it reported an error. Now the phone will not even turn on. I failed to record what the error message was before I closed the computer, since it didn’t occur to me that it would brick the phone and I figured I would try something else later. However, I can find the log files. None of them clearly display the error message but if pasting any of that info would help then I can.

    • It _might_ still be OK. The initial boot after the flash takes a very long time. If you feel a buzz when you press the Esc/On key then try leaving the machine for 15 minutes to see if it does eventually boot.

      When you say “middle of the download” do you mean the download from the Internet to your PC, or the download from the PC to the Gemini?

      • Adam Adam

        Still doesn’t boot, and when I plug the charging cable into the phone the charging light doesn’t come on. No haptic feedback from any actions like plugging in or long pressing ESC.

        I mean the download from the PC to the Gemini.

      • Adam Adam

        Well I re-ran the FlashTool and it seems to be working now. Thanks for the help!

  23. max max

    @Adam: did you use the Linux FlashTool Software? I could not get that to run and with it I experienced similar problems, and I was fearing that I bricked my device. I could however fix it with the Windows FlashTool, which still worked for me. I was doing lots of “LongPresses” on the Esc/Power button with and without USB cable connected. After a couple of times of doing this, the upload worked for me.

    However one needs to check that all parameters in the FlashTool are correctly set, in particular that it is set to “Firmware Update” and not “Download”.

    Another tip from experience: Do not try to do a dist-upgrade to testing, for me it broke the GUI completely. Will reflash stretch when I have time. I could resolve my keyboard issues (before the dist-upgrade) via the kernel update as described in (after also doing all the other recommended adaptions there).

    For the developers: I am looking forward to a testing-based Debian image, or to a guide which parts of the GUI system need to be recompiled/adapted with patches. Also GNOME3/firefox with EGL acceleration (like chrome) would be nice – I don’t know if that is in principle possible however. 😉

    • Adam Adam

      I used the FlashTool linked in the instructions, the one for Windows. I got that to run although with errors.

      • Adam Adam

        Never mind, re-ran the FlashTool and it seems to be working again. Thanks for the help!

  24. Matt Matt

    I, like many others, am having the problem booting to Linux. I seemed to have flashed everything properly but the button combo situation is convoluted. One thing I know for sure is the steps that are posted by Planet are definitely wrong. Using that combo, I always go to the recovery partition with “No Command”

    The step that I seem to have a bit of success with is holding Esc + Silver key until the unit vibrates, then I release the Esc keep. The unit sits there for a bit and seemingly reboots (mind you, I’m still pressing the Silver key). If I release the Silver key when the screen comes on, the device still sits there for a moment, then reboots and goes in to Android. If I continue to hold the Silver key, the device goes in to a boot loop.

    One thing I will note is that when I decompress the file with 7-zip, I get a CRC error on the debian.img file so that’s likely the root of my issue. Yes, I downloaded it and tried it again with the same results. I’ll try extracting with a different program and re-flash I guess. It would be nice if Planet would put the checksums out there with the links so we can verify the file integrity prior to flashing.

    • Matt Matt

      Ok, I extracted the file with WinRAR and got no errors, I proceeded with the flash and can get Debian to boot now. It’s SLOW, but it boots.

      The way I did it was to hold Esc + Silver button until I felt the vibrate, then I released the Esc key, still holding the Silver button. Once the screen came on with the Planet logo and the penguin, then I released the Silver key.

      GIVE IT TIME, it takes quite some time to load up Debian, like 2+ minutes.

    • I have mine set up to boot to Debian by default, but imagine that things are similar in reverse.
      Press Esc until it buzzes, then press the silver key
      The machine boots up, and shows a penguin and “Powered by Linux.”
      The “Powered by Linux” changes to “Powered by Androld” and the machine boots to Android.

      • Rick Roman Rick Roman

        mine is not set to Debian by default but I get the same behavior.

  25. Adam Adam

    This installs a 64-bit architecture right? Just checking because I tried to install Miniconda and it warned me that it looks like I’m trying to install 64-bit software on 32-bit architecture. Should I just ignore this warning?

  26. Here’s my solution to the Linux install issues….
    I kept trying to do it, and I kept bricking my computer. I had errors during the .zip extract process. Linux acknowledged the error, but went on, Windows just kept restarting the process, and kept getting the same error. Someone once said the definition of insanity was to keep doing the same thing, expecting a different result… In looking at the various posts, one person used a friend’s Apple computer to do the extract, then things started working. Got me to thinking, so I quit trying to use the Archive Manager in Linux, and did it with unzip at the command line. It downloaded, and worked. If you call this working. What is Linux with any functional networking?
    Now, how about getting a real ‘working’ Linux.?

  27. Nic Ferrier Nic Ferrier

    I’m having tons of problems with it.

    First, I select the linux file in the flash tool but it doesn’t have everything selected that is in the image above… there are only a few files selected.

    But I can’t select any more than is selected by default.

    I tried the process anyway and it does seem to download. But the Gemini won’t turn on at all afterwards. No feedback from the device at all.

    It seems it’s bricked?

    • Nic Ferrier Nic Ferrier

      Aha. So the items in the flash tool not being selected and being unavailable for selection is caused by the unzip not working.

      If you use a command line unzip (I used the one that comes with Windows’ git bash) then it’s all good.

      • Nic Ferrier Nic Ferrier

        If only the author would update the post and state some simple things:

        * standard Windows explorer extract will not work
        * the whole process frimware flash should take about 10 minutes

  28. First, see my post, above, about un-zipping the download. I did it in Linux, using UNZIP at the command line. Someone else did it using 7-zip (? I think), someone else had a friend un-zip it using Apple. The plain, gui-based options don’t un-zip it properly. Next, re-install the original Android to take care of the brick problem. A tall glass of your favorite libation might help. It will install. It will work, if a bit poorly. Also see the comment by ArchiMark, above. That set of instructions seems a bit more complete.

    I had the same Linux key combo problem, ending up in the recovery partition with “No Command”. I got Linux to boot by:

    1) Press Esc key (without pressing side key) to power up
    2) When the unit vibrates release the Esc key then press and hold the side key
    3) When the planet boot screen appears release side key

    Hope this helps!

    Is it me or the FlashTool link is broken?

  31. Must be you, the flash tool works for me. I’m now full tripple boot!

    My Gemini has now gone into “bricked” mode. It won’t turn on at all. Not even Android.

    Hold the power button down, gives a pathetic buzz periodically but nothing else happens.

    No screen at all.

    Perhaps the screen broke?

    Any help?

      Oh. It’s ok. It just hasn’t charged. Odd.

    Vous m’excuserez tout d’abord de parler ici dans ma langue, mais c’est pour éviter toute ambiguïté qui serait due à une expression équivoque.
    Je vous fais part de mon expérience de manière à pouvoir aider ceux qui ont dû comme moi tâtonner pendant quelques jours avant de comprendre comment mener à bien l’opération sans obstacle ni message d’erreur.
    Dans mon cas, le premier .zip proposé en téléchargement est inutilisable : remplacez-le par celui-ci : . J’installe habituellement Linux sur de vieilles machines, de manière à leur redonner une seconde vie. Ici, j’ai utilisé un PC récent, sous Windows 10 à jour. Prévoir 15 à 16 Go d’espace disque disponible, formaté en NTFS : vous éviterez tout souci au moment de la décompression, et les fichiers une fois décompressés prennent de la place !
    Avant d’entreprendre quoi que ce soit, commencez par décompresser toutes les archives. Soyez patient ! Cela prend un temps plus que certain.
    Suivez ensuite scrupuleusement le guide d’installation jusqu’à ce que vous soyez prêt à flasher l’appareil. N’oubliez pas que vous allez ainsi le remettre à neuf, et non pas seulement installer Debian en dual boot. Faites une sauvegarde de vos données personnelles avant de commencer !
    L’appareil doit être arrêté, mais toujours connecté au PC par le cable USB-C, évidemment, aussitôt après avoir cliqué sur le bouton « Download ». Il vous faut là encore patienter quelques minutes, et non quelques secondes !, avant l’achèvement de la totalité du processus. Tant que la barre de chargement, en bas de l’outil de flashage, sera toujours active, ne touchez à rien ! Si tout se passe bien, un message s’affichera au milieu de l’outil de flashage vous informant de la réussite du processus.
    Maintenant, vous pouvez débrancher le cable et rallumer votre appareil. Pour lancer Debian, appuyez sur la touche Esc jusqu’à ce qu’il vibre, relâchez-là, puis sur le bouton gris à droite. Le mot de passe Debian est « gemini », mais n’oubliez pas que votre clavier est alors par défaut un clavier US : sur le mien, pour obtenir la lettre m, c’est la touche ; . Une fois entré dans Debian, tout reste à configurer : le clavier, le wifi, la taille des caractères (la résolution de l’écran est par défaut de 2160×1080, ce qui rend xterm microscopique), etc.

    Has anyone managed to connect an external monitor to the Gemini while using Linux?

    I tried with a USB-C but didn’t get a signal apparently.

    • dirk dirk

      i have the same problem. Within Android the hdmi signal came out of the orginal usb-c to hdmi adapter from planet, but with linux, no signal comes out… i found nothing to configure on the planet-debian-linux to aktivate the external monitor… and nothing to read about that… can anyone help!

    The Link to the flash tool zip seems to be dead.
