i747m 4.1.2 Not Unlocking


HI There,

I want to unlock samsung i747m with version 4.1.2. I tried both nspro and pegasus box to unlock the phone everytime the error came failed to unlock.

Someone told me the version 4.1.2 is the culprit. Can someone confirm this or provide a solution.

I am using latest version 6.6.5 NSPro

Thanks,
Darsh

Okay first of all you don't mention it is 4.1.2....for all I know it could still be 4.1.1. Second, you had play around and find another model to choose from list, (t989) to do it. So technically if those who have maybe half a day to spare to try all Samsung models until one works that's fine but who would know that? I have Z3X box and don;t have time to try all model....hopefully it get's corrected and the right model is done.

You need JTAG.. riffbox. Did you flash the right firmware? i747M and i747 are different.

Do a factory reset/hard reset after downgrade.

Downgrade to 4.0.4 is unsafe?
Anyone succeeded in unlocking 4.1.2?
Thanks
