after fixing bootlopp IMEI problems
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 126.96.36.199 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 188.8.131.52, copied it to my sd card, entered recovery mod and flashed that CWM recovery 184.108.40.206..
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
