So I followed GLD's method of installing PE 4.2, I wiped data and formatted system and boot. I never formatted system nor boot before for a new ROM, but since it was in the instructions I did. Now the ROM has serious issues. Sometimes whenever I update an app the phone reboots, certain apps or games (like fruit ninja, angry birds etc.) force close all the time. I did restore the apps from titanium backup from a previous ROM, but I uninstalled the apps and reinstalled them and they still force close. I also wiped dalvik cache and fixed permissions and wiped my sd card, it didn't help. So I thought it was something wrong with the ROM itself, I switched to bugless beast and the same problems occur. How can I fix all this?!?
