Hey guys,
I have a HTC desire 820u Dual Sim, Indian version, bootloader locked, Stock Android 5.0.2.
Recently after updating the phone via OTA, incremental update, my phone started rebooting & became unstable & i lost mobile reception.
Then after i checked for the IMEI code by dialing *#06#, i see there is no IMEI, it has been wiped. I never tried rooting this phone, it was just the OTA update that did this.
Can anyone please help me to fix this ?
Thanks.

1. MY PHONE WHEN I GOT IT WAS F180S, VERSION: 4.1.2. UPDATED THROUGH PHONE IN 4.4.2. KITKAT.
THEN FOR ROOTING THE PHONE I CONVERT IT IN LOWER VERSION AGAIN 4.1.2 VIA KDG_UPDATER. AT THAT TIME THE PHONE STUCK AT LOGO, THEN FROM THE FORUM I HAVE SOLVED IT BY THE HELP OF A SENIOR MEMBER(GRATEFUL TO HIM) USING HARD RESET. I HAVE LOST THE IMEI THAT TIME AS NO BACKUP OF EFS MADE.
2. THEN I ROOT IT BY BINARY METHOD. AFTER ROOTING, THE NETWORK SIGNAL BECAME SO POOR.

Hi guys
BIG problem arose
My desire 816 is A5_DWGL ...I flashed CM12 and Everything works fine except that the sim card is not detected, i changed network to 2G and does no help..Press #*06# the IMEI is null
Then i flash back to stock sense rom. the IMEIs are back too.
Is there any possible the i back IMEI from stock rom, and then flash into CM12 rom? or is there another way to get my IMEI back on CM12?

UPDATE:

HELP PLEASE !!!
After flashing CM-12, Both SIM are not working. Flashed stock L firmware but still problem is there... any solution?
Hello,
As i am new to this forum and i am not sure that this will be replied. Still here is a little problem. Couple of months back my small brother bought HTC Desire 816 Dual sim Indian Variant (Qualcomm) phone which Cellular network was not working. Going deep in problems i came to find out that it has baseband version was unknown & IMEI was null. Some sites on google told flashing wrong ROM can cause this problem so find good ROM and Flash it. I Unlocked bootloader flashed custom ROM(Cynogenmod Nightly) via TWRP recovery. Still same problem. I tried that indian backup file tried different ROM but none helped. And yes when i tried to flash kitkat or lolipop or Marshmellow the phone just keeps restarting. Now i am using resurection Remix rom.
PS. Fastboot details Attached
Thanks
Hi everyone!
First of all sorry for bad english! I flashed my HTC Desire 526G Dual Sim some months ago and I recently restored the stock rom because of too many bugs in the custom roms I tested, using SP Flash Tool. What I didn't know was that formatting the phone before restoring it would have caused IMEI codes' loss, thus losing SIMs signal!
I currently restored IMEI codes with MTK Droid Tool (so I rooted the phone) but I still have no signal, does anybody have some ideas about it? :crying:
Thank you very much in advance!!!
Hi, i recently installed pixel experience on my s9 g960f and i was having one little issue that was part of my fault, so i reflashed the rom completely and my IMEI and baseband is gone, my sim card wont work at all. please help!
