From time to time, I come across some interesting situations ... I did an update on the ROM. I'm there are many days without sleep, because I can't change the IMEI of my "LG e612f". I've tried Terminal Emulator, Root, Update many ROMs, etc .... Downgrades Anyway, I used all my knowledge on Tools QPST and nothing works. Rewrite IMEI in Qualcomm Tools, SPC requires sending with its 6 digits, which I do not know!! I am in search of a solution, since the model there is no EFS folder.
