Gemini PDA - Linux / Re: NixOS on the Gemini - GPU / WiFi / most peripherals working

« on: October 10, 2026, 10:52:49 am »

very cool! i also started a similar project, my trees are here:

https://github.com/georgewhewell/nixos-gemini/
https://github.com/georgewhewell/linux-gemini/

main differences seem to be:

my boot chain is LK -> uboot -> systemd-boot -> EFI - it should be able to boot any distro with uefi images like this
i targetted linux 7.2 (the new `dmabuf` is useful for some things- e.g video encoder/decoder)
i targetted regular nixos, not nixos-mobile

hardware: i had codex write a driver for the cellular- it boots/scans and can see LTE network, i didnt try attach yet

Gemini PDA - Hardware / Unknown Baseband / No IMEI [SOLVED]

Hurray- my baseband is fixed! I followed instructions from this post- https://www.oesf.org/forum/index.php?s=&...st&p=287807

The Planet flash tool didn't allow me to select 'Format All + Download', so I found another 'SP Flash Tool' which did. After following steps in this post my baseband and IMEI are back. Thanks to everyone who help!

Gemini PDA - Hardware / Unknown Baseband / No IMEI [SOLVED]

Have you already tried to flash you nvram backup? Maybe this helps. From what I remember I did the Baseband fix 2 times. Maybe it helps doing it a second time.

Yep, I have tried flashing NVRAM backup a couple of times, but does not seem to help- I start to wonder whether I already had missing baseband problem when I took NVRAM backup- I think not though. Can you say exactly the order which you flashed original ROM, NVRAM, recovery, etc? Also, did you use the Android-only ROM, or a multi-boot image? I tried the following-

- Flash multiboot scatter with Linux + Android
- At this point android will not boot- gets stuck at spinning planets boot screen
- Flash NVRAM backup
- Android now boots, but no baseband
- Flash TWRP to recovery patition, reboot to recovery, install baseband fixer zip & wipe caches
- Now I cannot boot android- the device hangs at boot image with penguin

Perhaps you can share your scatter file, I can follow your procedure? Thanks for your help.

Edit: After waiting a while, it seems Android does boot after final step, but still no baseband

I have just got my baseband back by flashing the Baseband fix from http://x1grand.blogspot.com/2017/07/perman...ix-for-mtk.html using TWRP.

If you also want to give it a try install twrp  from here: http://x1grand.blogspot.com/2017/07/perman...ix-for-mtk.html. I just opened a root shell in android (Termux and then su) and installed via dd:

dd if=/mnt/m--external_sd/twrp-3.2.1-0-gempda.img of=/dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name/recovery

Then boot into recovery by  holding ESC.

In TWRP select Install. Then select the downloaded Baseband 20fixer.zip. Then swipe to flash. Afterwards I wiped Dalvik. Don't know if this is really needed.

Thanks for these instructions. I tried them on my X27 Gemini (exhibiting similar 'GSM Baseband: Unknown" problem) but it did not seem to have any effect. The TWRP recovery boot seemed to install the zip file without errors, but when I reboot to android nothing has changed. Does anyone have any ideas to debug this further?
