Im having a weird problem with my intl galaxy s3. Only EFS v1 modems, like LLX and MEX are working. Every modem and rom designed for EFS v2 folder cant read my imei number and shows me 00049 generic imei.
Ive tried install MG4 and MH5 modems and roms, stock and modified, but apparently my EFS folder dont upgrade or....dont know what.
When flashes older roms (EFS v1) my imei returns.
Anyone have any idea what might be happening and how to fix it? Or, maybe, is there any method to install older modems in newer roms?
