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

« on: July 15, 2018, 06:23:23 pm »

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!

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?
