I recently bought an AT&T Optimus G E970 (unlocked) and have rooted it using framaroot.
Now, when I try to unlock the bootloader using Freegee app from playstore, it FC's and phone reboots. the AT&T power-off animation is not present in my phone. When I try to boot into bootloader by pressing Vol. Up + Power key as given here http://forum.xda-developers.com/show....php?t=2001655 , the phone boots normally but not into bootloader.
Phone came with Jellybean 4.1.2. Last time when Freegee app finished downloading the .xml file, the phone got soft-bricked and I have to use LGNPST method to restore it using the stock firmware .tot file.
I'm not sure what is wrong with the phone. Is there any other method to unlock the bootloader offline?
