There is some good news for the discerning Galaxy Tab 2 10.1 users (including P5100, P5110 and P5113), as the latest Android 4.2.2 Jelly Bean custom firmware is now available via newly released CyanogenMod 10.1 (CM10.1) Nightly ROM. The latest firmware reportedly brings pure (stock) Android experience with Nexus-styled interface, and not the native TouchWiz UI.
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.
Key Points to Note
- CyanogenMod 10.1 Nightly ROM and the instructions given in this guide are applicable for the Galaxy Tab 2 10.1 P5113 model only and will not work with any other device. Verify the device's model number by navigating to Settings > About Tablet.
- Verify that the correct USB drivers are installed for the Galaxy Tab 2 10.1 on the computer (download USB drivers).
- Backup the important data and settings on the tablet by using one of the recommended custom recovery tools such as ClockworkMod (CWM) or TWRP recovery, in order to prevent data loss during firmware installation.
- Make sure that USB Debugging mode is enabled on the tablet by navigating to Settings > Developer Options (if the device is running Android 4.0 or later) or go to Settings > Applications > Development (if the tablet is running Android 2.3 or earlier).
