it started when i was using offical firmware jelly bean 4.1.2 (I9100XXMS1) rooted and i wanted to flash Cyanogenmod 11
to do so you need CWM recovery 6.0.4.4 at least but i had philz touch cwm based 5.0.x.x. (that kind of cwm i had with root)
so i downloaded CWM recovery 6.0.4.4, copied it to my sd card, entered recovery mod and flashed that CWM recovery 6.0.4.4..
so if im not wrong i flashed different version CWM recovery that i had..
because of it bootloop started.
somehow i managed to restore my phone back to working status. i had a lot of problems like "cant mount E:/ efs" and bootloop all the time but now almost all is ok
almost except IMEI...
i used some SGII_repair app so now i have signal but my IMEI is different than before.. no idea how to restore it.. why i need it? cause i cant enter my sim contatcs
and no i did not backed up my /efs folder before so i cant just copy nv_data.bin, nv_data.bin.md5
no idea what to do now.. i checked every topic about it and still dont know how to fix it
help..
No IMEI & no EFS backup = service centre or local mobile repair shop.
but according to that [GUIDE] Recover your IMEI in 9 steps.
i dont need imei or efs backup.. i did same as on guide and it did not worked.. still IMEI changed to 004999010640000
Exactly my point
well at least phone is working..
i can call and ppl can call me..
but its not my IMEI so its not good..
if they can do it at service centre or local mobile repair shop i cant do it myself?
Hello, I'm new member in here. Today I flashed UltimaROM to my SGS3. Before the flashing I installed Philz touch recovery and saved Nandroid, modem and EFS backups in my PC. After the flashing no IMEI number was shown and I got a message saying " Insert SIM card....". So i tried to restore EFS in custom restore option in philz recovery. Even though it showed restore successful , IMEI number is still unavailable and i couldn't connect to mobile network. I also tried ktools to restore efs but no result. Can someone please help me regarding this issue.
What version firmware did you have before you first flashed? If it was really old then that could be the problem.
Flash a 4.3 stock rom, factory reset them boot and see if your efs is read again.

Thanks for the reply. I had 4.1.2. If I flash 4.3 stock ROM can i retrieve my IMEI ?
If you flash a 4.3 stock it will update your efs to v2 and should enable it to be read in all newer firmwares.
Hi,
I messed up my NVRAM, no IMEIs nor MACs...
Can Someone provide me a full NVRAM backup or a working solution for restoring IMEIs?
(no luck with IMEI&SN Writer so far)
Thanks

If you flash a stock ROM that is flashable with SP Flash Tool, this will probably restore a working NVRAM. But this is not for the faint-hearted. If you can't find such a stock ROM, then you can try this custom ROM: http://www.needrom.com/download/xiaomi-redmi-note-2-hermes-cinafoniaci-rom/
As I said, this is not for the faint-hearted. If you are scared of trashing the phone, don't try it.
PS: next time, backup your NVRAM with TWRP recovery.
Try this:

good luck
Thanks for your help,
flashing stock rom with SP-Flash tool doesnt worked for me.
Restoring the files is only a temporary solution till next phone wipe.
I managed to wirte back my IMEI to nvram with "MAUI Meta", restoring Wifi and BT MAC with "SP Meta".
You find both tools on "needrom".
Does anybody know if there are other valueable things i have to restore after a nvram wipe?
(still searching for an backup, just toi be sure)
