Install CM 10.1.0 Final Build ROM based on Jelly Bean 4.2.2 for Samsung Galaxy Nexus I9250

CM10.1.0 How to install guide for Samsung Galaxy Nexus

CM 10.1.0 Final build has been finished and you can use this tutorial to learn how to successfully install it on your Galaxy Nexus International GSM variant. Read the entire tutorial and make sure that you won’t skip any steps that I have listed in this post, as you wouldn’t want to repeat the tutorial more than once.

This build of CM is the first Stable release and it’s a better version than the CM 10.1 M Snapshots/ Release Candidate and Nightlies releases. If you find any errors while using it, tell us in comments so that more users will learn about them before installing the update. We didn’t manage to find any major bugs, but there are still some minor ones which means that there is still work to be done by the CyanogenMod team.

First thing that you need to do is to read the guidelines listed below:

  • use this guide only with the Samsung Galaxy Nexus I9250 International version.
  • don’t try to use this guide with any other Android device, as you will end up bricking it.
  • your Galaxy Nexus has to be on an unlocked bootloader, rooted and running a custom Recovery such as CWM or TWRP.
  • this guide uses the ClockworkMod CWM Recovery, but you can also use the TWRP version if that’s the one installed on your device. In case you have TWRP, then you should carefully select the corresponding actions that I’ve listed for CWM.
  • use the Custom Recovery mode and create a full NANDROID backup of your current OS. This will set a restore file that you can use in case the new ROM doesn’t boot with your phone.
  • the how-to guide tells you to factory reset the phone, do it, as otherwise it won’t boot into normal mode, forcing you to repeat the tutorial more than once.
  • ‘factory reset’ will delete all contents from your device’s system partition, so you’ll lose all installed apps and other similar data.
  • use a tool from Google Play Store to backup installed apps data.
  • if you’re planning on backing up SMS, Call Logs info or APN Internet Settings, then you should use these tools: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore.
  • also, backup your Contacts info by syncing it with your Gmail account.
  • enable USB Debugging from Developer Options.
  • make sure that your device’s battery has enough power left before switching off. If the phone powers off in the middle of the installation process, you will be forced to repeat the entire tutorial once again.
  • use this tutorial only if you’re an advanced Android user.
  • note that we cannot be held responsible in case lose data or you brick the phone.
  • read the entire post and make sure that you won’t skip any steps.

Since you’ve read all of the above, you can now move on to the next part of this post and learn how to successfully flash the latest Stable build of CM 10.1 for your device.
