Hello I cant unlock my Samsung I9300. It wont detect phone. I have all samsung drivers installed and also put phone in USB debug mode. Any idea what it could be?

Junaid_UK · 12-23-2012, 00:08

Root the phone first

ADB RESORE, and my IMEI is correct, But phone isnt unlocked. I still get asked for network unlock

**Fast Unlocking** · 12-23-2012, 19:41

when backup is restored this mean phone back to original status.

4.1.2 seems to have changed security again by samsung, your only solution atm to unlock correct is via code read or buying unlock code.

until i get 1 of these versions in hands and check.

Yes that would be my guess, 4.1.2 could be the problem. Please let us know when you get this updated so we can unlock. Thanks
