Install Jelly Bean 4.2 on Samsung Galaxy Tab 2 Using CyanogenMod 10.1
Samsung Galaxy Tab 2 10.1 is one of those devices which have little to no chance of getting Android 4.2, also known as Jelly Bean. However the recent builds of CyanogenMod 10.1, which are rather unofficial, would install Android 4.2 on your device and would also boost the general performance.
Like any other ROM, this one would also void your device’s warranty. So, proceed at your own risk. Moreover, if you have not performed ROM installing in the past, please try it under a supervision.
- Make it sure official ClockWorkMod Recovery is installed on your device.
- Download CM10.1 unofficial build for your Tab
- Download Google Apps
Step 1. First of all copy the download GoogleApps and CM10.1 Zip files to your internal SD card.
Step 2: Boot into Recovery – For this purpose turn of your tab. Now restart it while holding down the volume down and power button simultaneously. Keep pressed both buttons until you see Galaxy Tab 2 10.1 logo. At this point you can release the power button but keep holding Volume down button for few more seconds until you see CWM recovery.
Step 3: While navigating in Menus using the volume and home buttons, back up your device first.
Step 4: First flash CyanogenMod 10.1 zip file using “Install Zip from SD Card” option.
Step 5: After that install Google Apps using the same command.
Step 6: Now do a data wipe/factory reset.
Step 7: Reboot your device.
Here are few more instructions from the official thread.
Don’t restore system data using Titanium Backup! Restoring Apps + Data might cause problems and is not recommended, avoid it if possible!
Upgrading from earlier version of CyanogenMod 10.1:
- Copy CM10.1 ZIP to your internal SDCard
- Boot into Recovery
- Flash CM10.1 zip from internal SDCard
