[Q] Flashing Stock ROM on Sony Xperia L - C2105
I have Sony Xperia L - Jellybean 4.2.2 - 15.3.A.1.17 - Rooted Stock ROM - Locked Bootloader
For some reasons I have to make a hard factory reset with Sony Update Service program, but instead of letting the program re-download the firmware then installing it on the phone, I already made the FTF file that I downloaded in the past by using the Flashtool.
Now The Question Is:
Have I worry about losing the DRM Keys when I flash this FTF with the Flashtool ?, or this kind of flashing will not affect it ?, or I have to check Exclude TA in the Flashtool ?
