The whole thing started when I turned on the BT (like one of decade times before). Phone was not even entering into main screen, at least for a while. Just was looping the 2 logos (Sony & Xperia).
1. I used Repair through PC Companion. Phone became usable, but I didnt see the BT status, because I didnt know the source of the problem, before I come here and read relative articles.
2. I turned off the phone for the night and the next day, the problem was there again.
3. I removed all cards (SIM & SD) and battery and attached them again many times. There was no improvement.
What can I do by myself, to avoid an expensive service by a technician? Thank you in advance.
