  • I resturned to ICS 4.0.4 because the JB ROM is still very unstable und produces frequent crashes. Seems to be an experimental version. Perhaps JB 4.1.1 ROM’s will get stable in a few weeks . . .

  • Upgraded my P6810 (from Oz) to latest 4.1.1 nightly build from 16 Aug using these instructions. After 2 days absolutely no issues. Everything working as expected battery life the same if not better and NO crashes. Went from stock to 4.1.1 and wow, speed and general usability much improved. When installing CM10 had to flash twice, and first time didn’t boot, and second perfect.
