Is there any solution to sim unlock the galaxy s3 on android 4.3 with the changed efs partition (v2)? I read a bunch of threads and the conclusion is it can't be done.
I have a couple of questions though:
I do have V1 backups of the efs folder. Is it possible to flash an older firmware, 4.1.1 for example and then restore the old efs backup and use the galaxsim unlock solution ? if i do this and upgrade the phone to 4.3 afterwards will it still be unlocked or i`ll remain stuck with the 4.1.1 rom ?
If i keep the current 4.3 rom and just modify the efs partition with the backup i have (v1) will it work ? i read in the faq thread that the newer firmwares still read the old efs format so it should be ok right ?
