Alex, please, answer me in portuguese. I can read it. Your answers maybe are from a automatic translator, and I can't understand very well.

I don't have a firmware backup previously of lock. I have a full save from Flash&Backup of the phone data, but I used it and nothing happen. The firmware I flashed to is from TELCEL. The original was from Digitel.

I think tha Flash&Backup only save some parts of the software, but it doesn't save the loader, boot or something. When I use the old backup, all the screens change to Digitel, but it still ask for the Subsidiary Code!

Now I used a program called SBF-Recalc, ver. 1.2.8. I read in a forum that this program could unlock the subsidiary lock. It found 2 and unlocked it, but the phone still ask for the subsidiary code.

I'll keep researching and'll keep you informed.

Thanks!
