I think you're making a confusion between "debranding" and "unlocking".
If you want to debrand add to "Files" pannel :
W760_R3EF001_MAIN_GENERIC_VT_DE_RED52
W760_R3EF001_FS_ISRAEL_RED52, and put this tpa.zip to "MISC Files",
then hit "Flash".
If you want to unlock, use this:
Aerix - free unlock A2 platform - Top Sony Forums
