I debrand two w580i phones. One works perfectly after the debranding. The other one flashed with no error and the phone works fine except the display is bad. The words are big and fuzzy. It seems the display setting is wrong but I can change that. It might be the phone was demaged at flashing. I flashed again on that phone. The cellphone screen display is still the same bad as before. It was AT&T brand cellphone. Can anyone help on this problem?
