It seems that the developers along with consumers just cannot get enough of the Samsung Galaxy Note 2. While the device is to get the update to Jelly Bean 4.2 at some point, there is no date for it. So if you are fed up with the wait you can install now thanks to a custom ROM.
You do make the update at your own risk as it is an unofficial one and care has to be taken.
Before going ahead and making the update you need to be aware of the following.
Check to make sure that the handset is the Samsung Galaxy Note 2 from T-Mobile. AT&T or Verizon. You also have to have the device rooted.
You will need around 70% battery to make sure that it doesn’t run out.
The handset also needs backing up.
You might want to turn off the security on both the computer and the handset.
Go into the settings of your handset and into application development and check that USB debugging is enabled.
You should have installed ClockWorkMod or something similar.
You also need to download the ROM to the computer and make sure that you read any instructions that come with it.
Once you have done all of the above follow the instructions below.
1. Install the Samsung USB drivers on your computer.
2. Connect your Galaxy Note 2 to the computer then copy the appropriate custom ROM and the Google Apps package on the SD card of your device.
3. Switch off the Samsung Galaxy Note 2 and reboot it into Recovery mode. To do this, press and hold the Volume up + Volume down + Power keys after the device turned off.
4. Create a nAndroid backup for your current ROM which you can restore later if something goes wrong. Select “backup and restore > backup.” You can select “restore” if you decided to revert back to your current ROM.
5. In the main menu, select “wipe data/factory reset” and “wipe cache partition.” After that, go back and select “advanced > wipe Dalvik cache.”
6. Go back to the main menu and select “install zip from SD card > choose zip from SD card.” Choose the custom ROM zip file you have copied on your Galaxy Note and confirm installation. Do the same with the Google Apps package.
7. Once the installation is complete, go back to the main menu and select “reboot system now.”
8. The Samsung Galaxy Note 2 will reboot and may take up to 5 minutes to complete the first run of the latest ROM.
If all has gone well you should now be running Jelly Bean 4.2.2 on your Samsung Galaxy Note 2. The ROM comes with everything that PACMan, Paranoid Android and CyanogenMod offers.
