While owners of Samsung Galaxy Note 10.1 are waiting for the roll out of the official Android 4.2 Jelly Bean update for their device, XDA Developers have been busy developing a custom ROM based on CyanogenMod 10.1 that brings along Android 4.2.1. A nightly build of CM 10.1 Jelly Bean has recently been released putting the device on par with Google’s Nexus devices, albeit unofficially.
If you are one of the owners of Galaxy Note 10.1 with model number N8000 and is willing to take the risk of flashing custom ROMs and firmware into your device, then this tutorial might serve you well as it will walk you through the installation process. It is imperative that owners of Note 10.1 devices with different model numbers should not follow this tutorial as it may lead to their devices being bricked.
Here are some things you need to check prior to taking the first step of this tutorial.
- Check if you are sufficient battery left in your device. You should, at least, have 75% battery left to ensure a safe installation, however, if you can fully-charge the battery before doing this tutorial that would be great.
- Backup all your data just in case things go wrong during the process. Here is our guide on how to backup data and files in your Android phone.
- Make sure you have rooted your device first because you will need root access to flash unofficial ROMs and firmware. Here’s how you root your Android device.
- You will need to first install ClockworkMod Recovery because you will be using it to flash CM 10.1 Android 4.2 into your Galaxy Note 10.1. Here’s a walkthrough on how to install ClockworkMod Recovery.
- Download CM 10.1 Android 4.2 Jelly Bean nightly package and save it into your computer.
- Download Google Apps and save it into your computer, too.
If you’ve already flashed several ROMs or firmware to your device before, then you know what to expect when you mess with simple steps.
Step 1: Connect your Galaxy Note 10.1 to your computer using the data USB cable and copy the CM 10.1 Jelly Bean and Google Apps packages into your internal memory. Make sure you save them in the root directory because that’s the only directory ClockworkMod Recovery can detect. Saving them into deeper directories would make those packages undetectable.
Step 2: Turn the Note off and boot it into Recovery Mode. You can do so by pressing and holding Power and Volume Up buttons simultaneously until the screen turns on and enter CWM Recovery mode.
Step 3: Perform a Nandroid backup of your existing ROM that you can restore later. Choose “Backup and Restore” option then “Backup.” After doing this, you can return to the main recovery menu.
Step 4: Look for “Install zip from SD card” option and press the Power button to confirm. Now select “Choose zip from SD card” and browse through the directory where you saved the packages. Of course, you need to choose the CM 10.1 Jelly Bean package to start flashing the custom ROM into your device.
Step 5: Follow step 4 but this time choose Google Apps package.
Step 6: Once installations of both packages are finished, choose “Reboot System now” to restart your device. Wait until you see the home screen before doing anything.
That’s all of it! Your Samsung Galaxy Note 10.1 with model N800 is now running Android 4.2 Jelly Bean CyanogenMod 10.1 firmware. And just in case you are wondering what “nightly build” is, we advice you to read this article from Wikipedia.
