Most of us know that we can flash custom roms or can root device only after UNLOCKING the bootloader from fastboot mode.
If you relock your bootloader, you will need to do a full backup-and-restore whenever you decide to unlock it again.
I got my unlock code from ATT but I can not seem to find a way to unlock it, either with the ATT sim in or a TMobile one. Previously using methods here on XDA I was able to unlock the SIM lock; the Subset lock; the SP lock and the Corporate lock. Going into Diagnosis all of those locks are disabled. However, the Network lock is still enabled.
I'm new to this forum but not all new to the world of phones/rooting/flashing and all that good stuff. I was looking for a way to unlock the i747 so I can use it with different carriers when traveling abroad. The only thing that I found was unlocking it with the stock 4.1 firmware.
I had succefully repaired T889 Tmobile baseband with modem flash method.That was damage during root.But now phone is succesfully unlocking with unlock codes but again asking for unlock codes and even after unlock there is message "invalid sim card".
Phone was orignaly at T889UVALL4_T889TMBALL4_TMB (Basebadn Damage).
I was pretty sure this question wouldve been already asked, and I tried hard to find a solution but couldnt find much.
I'm trying to lock/unlock my PC from my Android device. I dont want to use BTProximity to do this because even if I'm in another room in the house, it would be able to detect my phone and unlock the computer.
I received an unlock code from AT&T for my One XL. The unlock code comes up as unsuccessful. I followed the unlock instructions exactly. And I've called back and verified that AT&T has the correct IMEI and double checked the unlock code. I've never had an issue unlocking a phone before.
