Galaxy Tab 2 10.1 P5100 is among the lucky few Android devices to receive the latest Android 4.2.2 Jelly Bean firmware via the popular CyanogenMod 10.1 (CM10.1) Nightly ROM. The custom firmware reportedly brings near perfect and pure (stock) Android experience with minimal bugs or barely noticeable issues.
The CM10.1 Nightly ROM brings a host of latest Jelly Bean features with its Android 4.2.2 build, which is based on the original Android Open Source Project (AOSP) release.
NOTE: As the firmware is a nightly release, it may harbour a few untested bugs or broken features leading to FC errors, boot loops, app crashes or in the worst case the phone may fail to boot. In any such case, just reinstall stock firmware or any other stable custom ROM.
