Unknown Baseband / No IMEI [SOLVED]

[bled82]

I had issues with a flash got the no sim detected icon , was able to resolve with the following .

reflash with the firmware download option
flashed twrp and got root
with terminal emulator, SU
then 'AT+EGMR=1,7,"IMEI"' > /dev/radio/pttycmd1   . NOTE: you need the "" around your IMEI number also dont forget the ' after the second "
should return you to the # prompt without response then reboot device .

Nope, no luck with that. I had tried that before, but I've now done it a few more times, just to be sure...

Had the issue happen again was able to get service back by flashing http://support.planetcom.co.uk/download/An...A3_12062018.zip with the firmware upgrade option , at which point it booted android and had 3g service . Hope this helps .

EDIT: Sims detected no imei after flash but better than the no sim error , going to try a few things and update .

EDIT 2 Solved :

1:Flash Fota3 firmware firmware upgrade option
2: Boot android verify sim detected
3: Flash desired firmware with firmware upgrade . I flashed the newest with root android primary and debian as boot 2 , and twrp
4: boot android wait for sim detection then shutdown
5: boot recovery and flash magisk to allow root
6: boot android finish root setup and enable adb
7: adb and run : echo 'AT+EGMR=1,7,"IMEI"' > /dev/radio/pttycmd1
8: then : echo 'AT+EGMR=1,10,"IMEI"' > /dev/radio/pttycmd1
9: Reboot to android and should have cell service .

I've had this problem and I've been trying to solve it, happy to see I'm not alone.

I was unable to make any progress though. I've been logging my attempts here.

I've tried every solution here and many others to no avail.

Well, I have now given up. Have contacted Planetcom support, and they had no more tips for me, so I will be sending my Gemini back to them for service...
