well after having my phone unlocked to a new carrier for a couple of months. Yesterday i ran out of battery and after charging and the phone rebooted i lost the unlock is there any way to get it back??
The *only* way to keep your unlock is if *you used the SAM unlock when it did work, then backed up the activation ticket in the Lockdown folder with redsn0w or any other method*.
So unless you backed up the activation ticket after using the SAM unlock..........then no.....you will never be able to use the SAM unlock ever again.
