Recently I updated the software on my 3310 to the version 5.79 language pack B. I also flashed a 3310 eeprom.
After updating the FAID, removing locks and updating IMEI (to the one written inside the case) with rolis' noktools, I put the SIM card back in and powered on the phone.
I entered the PIN code and then got the usual display. "Menu" at the bottom, battery bars at the right but no aerial bars at the left. The middle of the display, which usually shows "VODAFONE", was also blank.
Keypad tones went silent after around 10 seconds and less than a minute later the phone reset. Any numbers dialled claim "No network coverage".
The phone continues to periodically reset.
Any ideas what I can do to rectify this?
