Asked some questions about this on the discussion. But wanted to report as well.

Constant freezing at startup of phone. (at first WLAN failed to turn off after a forced gallery update).

After than, restarted the phone and it froze every time. Was able to flash back to 3.0 from 4.3

Here is my phone:

N79-3 RM-350

Firmware 11.049.234.3
