Flash CM 10.1 M3 Snapshot custom ROM for the Google Nexus 10

CM10.1 Nightlties Android 4.2.2 available now

The CyanogenMod 10.1 3rd M snapshot build based on Android 4.2.2 Jelly Bean has been released for the Google Nexus 10 tablet and, you can learn how to install it successfully using the guide below.

This latest snapshot of the CM 10.1 M3 ROM is much more stable than all the previous Nightly builds. It packs the same features but it brings better ROM that should offer you the possibility to test all parts of your tablet. If you want to install this CM 10.1 M3 on your Google Nexus 10, then you should first read the guidelines below:

  • Use this tutorial only with the Google Nexus 10 tablet. Don’t try to flash these files on any other Android device as you will end up bricking it.
  • The Nexus 10 tablet you’re about to update has to be rooted, running a custom Recovery and having its bootloader unlocked.
  • Create a NANDROID backup of your current ROM using the CWM Recovery mode. You can also use the TWRP Recovery if you have that one installed. This will set a restore point for your tablet and you can use it in case something goes wrong and the new OS doesn’t boot.
  • Backup all your important data before moving to the tutorial. You will have to ‘wipe data/ factory reset’ the tablet before installing the new ROM.
  • Make sure that your tablet’s battery has enough power left before it switches off.
  • Enable USB debugging option from the Android Developer Options.
  • Don’t skip any steps that I have listed in the tutorial.
  • In case you cannot complete the installation, then you should ask for more help in our comments section.

These were all the preparation steps you had to take before starting the installation.

NOTE: In case your tablet is already running on a previous build of CM 10.1 M snapshot or Nightlies, then you can skip the ‘factory reset’ step and install the new ROM over its old build.
