Galaxy Tab 2 users can now enjoy the latest iteration of Jelly Bean software (Android 4.3) on their handsets, thanks to the nightly build release of CyanogenMod 10.2 (CM10.2) ROM by CM team. The CM10.2 ROM is based on the original Android Open Source Project (AOSP) release, which offers a very fast and stable Jelly Bean experience on latest Android 4.3 platform.
Head over to the XDA Developers source page (check link below) to learn more about this ROM.
Key Points to Note
- The CyanogenMod 10.2 ROM and the instructions provided are limited to Galaxy Tab 2 P3100, P3110 and P3113 models only. Verify device model number by navigating to Settings > About Tablet.
- Back up data and settings using a recommended custom recovery tool such as ClockworkMod (CWM) or TWRP, as data wiping process is mandatory in this tutorial.
- Download and install the correct USB drivers for Galaxy Tab 2 on computer.
- Ensure USB debugging mode is enabled on tablet by navigating to Settings > Applications > Development or Settings > Developer Options.
- Double-check that device has at least 80% battery charge to prevent unexpected device shutdown (due to battery drain) while installing ROM.
- Verify if the device is unlocked (not locked to specific carrier) and rooted with ClockworkMod Recovery (CWM) installed.
- If device is stuck at booting or experiences boot loop issues, Wipe Cache Partition and Wipe Dalvik Cache a few more times before rebooting.
- Allow newly installed ROM to stabilise for five minutes before using the device.
- If a Status 7 error message flashes while installing firmware, it could be due to an incompatible device or absence of a necessary kernel (for instance, a Jelly Bean Kernel must be installed before installing any Jelly Bean ROM).
