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
