Update Galaxy Note 2 with Unofficial CM 10.1 Android 4.2 ROM

The most popular custom ROM for the Android platform, the CyanogenMod custom firmware, is now available for the Samsung Galaxy Note 2, so as usual, we will be checking in how to install the latest CM 10.1 Android 4.2 Jelly Bean software on your Note 2 phablet. The update is not yet official, because the CM team is still working for providing a stable variant of the ROM, though the unofficial port of the OS has been already released by those of xda-developers. Therefore, during the following step by step guide, you will learn how to update the Galaxy Note 2 with the unofficial CM 10.1, so take note that this is not the stable variant of the Android 4.2 Jelly Bean based ROM.

Also, this is not an OS update released by Samsung and the firmware has nothing to do with the mentioned company. That’s why, for installing the CM 10.1 custom ROM on your Note 2 you will have to apply a manual and risky method. Of course, the warranty will be void, so be careful in what you do and try not to mess things up. Anyway, if you will follow my directions everything will be fine. For that, you will have to begin with the pre requisites and only after completing the same you will be able to safely flash the Android 4.2 software on your Galaxy Note 2 handset.

Now, as mentioned in the introduction, this is the beta version of the CM 10.1 ROM. Furthermore, the platform has been developed and tested on the Note 2 by those of xda-developers and according to them there are still bugs and issues in the Android 4.2 Jelly Bean system. You shouldn’t worry though as the problems will be resolved in the coming days and an improved version of the update will be made available. Since now, there have been reported the following bugs (for more details check out our source page by clicking on the link from here):

If you think that you can use the CM 10.1 software and update your Galaxy Note 2 to Android 4.2 Jelly Bean by installing the same, then we should get started with the pre requisites. I have detailed the preparation tasks on the list from below; be patience and try to complete all the steps from there. Else you will risk in bricking your beloved device and I know that you don’t want that to happen.

  • First of all, backup the Samsung Galaxy Note 2. It is recommended to save all the data (text messages, call logs, EFS, internet settings, market apps and so on) and also the current ROM; in this way, if you don’t like the new software, you can easily restore and re-use the stock firmware.
  • Root the Note 2 because the CM 10.1 is a custom ROM and not an official OS released by Samsung. The update must access the internal system of your phone and the root operation is the only way for providing the same.
  • The warranty will get void now, so always use a step by step guide, don’t apply things by yourselves.
  • The warranty can be restored if you downgrade to the stock ROM, or if you flash an official OS which comes straight from Samsung.
  • On your Galaxy Note 2 a custom recovery image (such as CWM recovery) must be installed. This tool is the core of this operation so you can’t go any further without it.
  • The CM10.1 file will have to be downloaded on a computer first, meaning that you must have access to your phone’s USB cord.
  • For ensuring that nothing is interfering with our work, deactivate the security programs that are running on your computer and phablet before starting the update process.
  • Also, for being sure that your device will not get turned off in the middle of the installation procedure charge its battery before heading to the proper steps. This task can be skipped if there is more than 60% power left.
  • Enable the USB debugging option on your Galaxy Note 2.
  • Apply the tutorial only if you own the mentioned Android based device, because the Jelly Bean 4.2 based CM 10.1 software will not work on a similar handset.

How to Update Galaxy Note 2 with Unofficial CM 10.1 Android 4.2 Jelly Bean ROM Firmware

  1. On your computer, download the latest version of the update from here and the Google apps package from here.
  2. Then, copy these files on your handset (to the SD card, don’t extract the files).
  3. Turn off the phone because you will have to boot into CWM recovery.
  4. For that you must press and hold the Volume Up, Home and then the Power buttons together until the screen turns on.
  5. The recovery menu should now be displayed.
  6. From there first of all, select “wipe data factory reset” and “wipe cache partition” (remember to backup the data before applying this step).
  7. Return by selecting “+++go back+++”.
  8. Then select “install zip from sd card” followed by “choose zip from sd card”.
  9. Pick the update file and flash it.
  10. Next, do the same for installing the Google apps package too.
  11. In the end, select “+++go back+++”, “reboot system now” and you are done.
  12. The first boot will take longer than usual; that’s a normal thing to happen.
