Update Samsung Galaxy Tab 2 (10.1) with unofficial CM 10.1 Android 4.2.1 ROM

The Galaxy Tab 2 10.1 variant has received its own unofficial build of CM 10.1 and you should use this post to learn how to successfully install the new ROM. Read all the instructions that I have listed and make sure that you know what you’re doing before starting to flash the update on your tablet.

CM 10.1 is based on the Android 4.2 Jelly Bean and the build in this post has been released by ‘codeworkx’, a well know CM developer. This is currently a simple experimental build of the popular ROM. It brings support for lockscreen widgets, multi-user , daydreams, 360-degrees panorama with the PhotoSphere camera function, Gesture typing keyboard and improved performance along with a more stable ROM.

Since this build of CM 10.1 is experimental you might find bugs and errors. At the moment, the home screen of your tablet will stay in Landscape mode only, and the screen might not power on when trying to unlock it. These are the only known bugs in this CM10.1 experimental ROM release.

Learn how to correctly set your device and make sure that you won’t lose any using the guidelines below:

  • Use this tutorial only with the Galaxy Tab 2 10.1 variant tablet. Do not attempt to flash these files on any other Android device. It should work with the P5100, P5110 and P5130 tablet model versions.
  • Your device should be rooted and running a CWM Recovery image. Without these you cannot complete the installation of this new ROM.
  • Enable USB debugging option from your device’s developer options.
  • Charge your tablet’s battery so that you won’t see it power off in the middle of the updating process.
  • This is a tutorial that should be installed only by advanced Android users. Don’t use this guide if you’re a novice, as you might end up bricking your device and that is something that you won’t want to happen.
  • Create a full NANDROID backup of the current ROM. This will come in handy if you cannot flash the new update or in case the Galaxy Tab 2 doesn’t boot normally after applying the changes.
  • Note that we cannot be blamed if your device is bricked nor can we be held responsible if you lose any important data that is currently stored on your device.
  • Use applications to backup your installed apps, SMS and other important things that are currently stored on the tablet. However, if you try to use this ROM only for testing purposes then you shouldn’t create backups as you will eventually restore the ROM backup file.
  • Apply all the steps I’ve listed and make sure that you don’t skip any steps I’ve listed.

These are all the steps that you had to take and now you should move to the next part of this guide. If you cannot complete the update, then you should ask for more in comments.

How to update Galaxy Tab 2 10.1 with experimental CM 10.1 Android 4.2 ROM:

  1. Download the ROM from HERE for P5100 model number. For the P5110 and P5130 model use this link here. Save the file on your PC desktop screen. Do not extract.
  2. Get the Gapps for Jelly bean from HERE. Save it on PC and don’t extract the contents.
  3. Connect your tablet to your PC using the USB cable. Move both files on your device’s internal SD card. After the transfer is complete you need to disconnect the Galaxy Tab 2 from PC.
  4. Power off the tablet and then boot it into CWM Recovery mode. It can be done if you press ‘volume down’ and ‘power’ buttons at the same time. Release the buttons when the recovery screen loads.
  5. Select the ‘backup and restore’ option to create a full NAND backup of your ROM. If you already have such file then you can skip this step and continue to the next one. NOTE: if you don’t have a ROM backup then you shouldn’t get to the next step as that one will wipe data from your device and you won’t be able to restore your device to a working state in case something goes wrong during the update.
  6. You’re now at the main menu of CWM Recovery and you need to select the ‘wipe data/ factory reset’ option and then confirm this action from the new screen. When this is done, get to the next step.
  7. Choose ‘install zip from SD card’ and after that select ‘choose zip from sdcard’ Find the ROM file and confirm that you do want to install it. Wait until the ROM is successfully installed and after that you can repeat the same action and flash the Gapps file.
  8. When the ROM and the Google Apps zips are installed, return to the main recovery screen and select ‘reboot system now’.
  9. Now your tablet will reboot and you should wait until you see the homescreen of the new CM 10.1 experimental ROM home screen.
  10. Test all the new features you find and tell in comments if it has improved the overall performance of your device.

In case you don’t like the new ROM, then you should use the backup ROM file and restore it using the CWM Recovery mode.

If the first boot process of the new CM 10.1 ROM takes too long to complete, you will have to power off the device and after that you should repeat the entire tutorial from step 1. Eventually you should be able to flash all the required files and get the latest experimental build of CyanogenMod 10.1 ROM on your Galaxy Tab 2 10.1 device.
