AT&T variant of the Samsung Galaxy Note can be upgraded to Android 4.2.2 JB with the latest build of CM 10.1.0 Release Candidate ROM. Use all the instructions that I've listed in this post and you should be able to flash all the new files at your first attempt.

The CM 10.1.0 RC2 build packs all the Jelly Bean 4.2.2 plus other CyanogenMod-based functions that will improve the overall performance of your device. In order to make sure that you manage to flash this new custom ROM for your AT&T Galaxy Note, then you should first take a look at the guidelines below:

  • use this tutorial only with the AT&T variant of the Samsung Galaxy Note device. Don't try to install any file that is listed in this post on any other smartphone.
  • the phablet has to be factory unlocked, rooted and having installed a custom Recovery image on it. I've used the CWM Recovery for this guide, but you can still use the TWRP variant, if that's the one that is installed on your device.
  • you need to use the custom Recovery and create a NANDROID backup of the ROM that's currently installed on your device. This will set a restore file of your Android operating system that can be used in case the phone isn't capable of booting into normal mode with CM 10.1 RC2.
  • backup the Call logs info, SMS data and APN Internet Settings using the following tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access has to be granted for some of these apps.
  • the 'how-to' guide will ask you to wipe data and factory reset the device before installing the new ROM. This means that the contents from the system partition will be removed in the process and you will lose the installed apps and other data stored in it. The files stored on the internal SDcard will not be removed.
  • sync your Contacts data with your Gmail account so that you won't lose any important phone numbers by installing this new ROM.
  • enable the USB Debugging option from the Android Developer Options menu.
  • the phone's battery should have enough power left before the phone switches off as you wouldn't want for that to happen in the middle of the updating process.
  • use this tutorial only if you're an advanced user who want to test and use as a daily ROM the CM 10.1 RC2 build.
  • note that we cannot be held responsible in case you lose any important data files or you brick the phone.
  • read the entire tutorial first and don't skip any steps listed below.

NOTE: if your device is already sporting a previous build of the CM 10.1 ROM, then you can skip the 'factory reset' step and install the new ROM over the current one. Such process is known as 'dirty flash'. But, in case you skip the step, you install the new ROM and the phone doesn't boot with it, then you will have to return to the tutorial and apply the 'factory reset' action; as that might be the reason which prevents your phone from booting with CM operating system.

Now that you know all of the above, you can continue to the next part of this article and learn how to update your phone with the latest Jelly Bean CyanogenMod build.

How to install CM 10.1 RC2 Android 4.2.2 custom ROM for the AT&T Samsung Galaxy Note:

  1. Download the CM 10.1 Release Candidate 2 ROM zip from HERE. Save the file on your computer and don't unzip its contents.
  2. Download Gapps for Jelly Bean 4.2.2 / CM10.1 ROMs from HERE. Don't extract the contents and save the file on your PC.
  3. Connect the Galaxy Note to your PC via USB cable. Move both downloaded files onto its internal Sdcard storage. After the files are copied, disconnect the device from PC.
  4. Power off your phablet device now.
  5. Boot it into CWM Recovery mode like this: press and hold Volume Up, Home and Power buttons. Release the buttons when the custom recovery mode screen appears.
  6. Select the 'backup and restore' option from the main custom Recovery screen. Create a NANDROID backup of your currently installed ROM to setup a restore point for your Note.
  7. Select 'wipe data/ factory reset' option and confirm this process. NOTE: remember that in case your device is already sporting a previous build of the CM 10.1 ROM, then you can skip this step.
  8. Now, select 'install zip from sdcard'. From the next screen select 'choose zip from sdcard' and find the CM 10.1.0 RC2 zip. Confirm that you want to install it.
  9. When the ROM is installed, select 'choose zip from sdcard'. Find the Gapps zip and install it.
  10. After both files have been installed with success, return to the first menu of the Recovery mode.
  11. Select 'reboot system now'. Wait several minutes before the first boot process of this new OS completes.
  12. Enter your Google Account details when the CM 10.1 Jelly Bean home screens is loaded and take control over your phone.
  13. Start testing all the new CyanogenMod settings. That's it, you've managed to update your device with a brand new CM build.

NOTE: In case your device doesn't complete the first boot process or the phablet enters a boot loop, then you should power it off completely. After that you will need to repeat the entire tutorial once again. The second time you should apply all the steps without skipping any actions. Make sure that you 'factory reset' the device as that might be why the phone didn't boot.

If you didn't manage to install the new OS on your Galaxy Note AT&T for various reasons, then you should leave a detailed comment in the field below and we will try to offer you the best solution to your problem. Remember that this is a guide for advanced users and for those who want to tinker with their smartphone's operating system.

If you don't like how the CM 10.1.0 RC2 ROM works with your smartphone, then you should boot again into CWM Recovery mode and restore the NANDROID backup of your previous ROM.
