I am using w580i for last one year. It has AT&T SE, but its unlocked. Now using with Tmobile.
So i am not asking for unlocking. I want to debrand it.
I tried the xs++ tool, but the version i used said the phone is not supported.
I was trying to see which one would work, obiviously i am googling and searched this forum and ended up with many files and confusion as end of 4hours search. Its my first time to flash a firmware but i am not new to mobile concepts.
i need,
1. The tool which i should use to debrand [w580i cid53]
2. Files needed to flash my mobile.[fbn, mbx,custom....]
3. How to backup my existing state of my mobile. [I have the sony suite and i backed up once with PC]
Any help would be extremely appreciated.
