I've been having some trouble getting custom ROMs to fully boot on my girlfriend's Galaxy Tab 2 (p3113). I was able to gain root access (I used this method: http://forum.xda-developers.com/show....php?t=2510669) and managed to install the latest CM rom, SlimRom, or OmniRom (with their respective Gapps).
However, I always run into the same problem: whenever I reboot from recovery (regardless of which rom was installed), android begins "optimizing" apps (presumably because I've cleared caches, including dalvik) and at the end, reports 2-3 process that have unexpectedly stopped, and reboots. I've done clean wipes with each install, and even tried re-downloading the roms, but nothing seems to work. Also, it doesn't seem like the stopped processes are consistent between roms. For example, the CM rom would report calendar and keyboard processes that have stopped, whereas Omnirom would report mediastorage and google search processes that have stopped.
Anyone have any ideas of what I can do to fix this?
