As more and more devices are receiving the Android 4.2 Jelly Bean flavor via custom ROMs firmware, now the Galaxy Tab 2 7.0 can be included on the list as the preview build of the CM 10.1 software had just been made available and can now be installed on your tablet. So, if you just can’t wait for the stable variant to be released, this beta version should be perfect for you. The CM 10.1 ROM will run perfectly on your Galaxy Tab 2, though there are bugs in the system and few issues that have been reported by those who had already tested the update.

This is not the official CM10.1 update and furthermore the same is not an official ROM released by Samsung for your Galaxy Tab 2 7.0. There are no words of when the Android 4.2 Jelly Bean OTA update will be launched for your tablet, therefore installing a Jelly Bean 4.2 based software should be exactly what you are looking for. This firmware was developed and tested on the Tab 2 by those of xda-developers, the OS improvement being still on its beta (preview) stage. This means that not all the features will work and there might be minor bugs in the system; for learning more about these aspects check our source page from here.

Also, before heading to more complex aspects related to the update operation that you are about to complete, you must know that the present CM 10.1 software is working only for the WiFi version of the Samsung Galaxy Tab 2 7.0, so don’t try to flash the same on a similar device as you will end up in bricking your beloved handset. Furthermore, foe being sure that nothing bad can happen with your Tab 2 while trying to update it to Android 4.2, you need to complete the pre requisites first. It is extremely important to read all the lines from this step by step guide because this is being considered a complex and risky operation.

When you are dealing with such operations, the first thing you must take care of is the backup. In this way you can be sure that all of your personal info will be in safe hands and you can’t lose anything that is being stored on your handset. So, go and complete a full and safe backup. You have suitable guides explained here on Android.gs; don’t hesitate and use our tutorials by searching through our how to section as you have all the details needed explained there.

Then, the CM 10.1 software will work only on a rooted system. Go and root your WiFi Galaxy tab 2 7.0 and then return here and resume the rest of the tasks. You should know that the warranty will get void, these operations being unofficial ones and you will be making changes into the internal system of your tablet. This means that if something bad happens and you brick your handset then you will be by yourselves. It’s not that easy to apply the Android 4.2 update so be careful. For the future as a final tip, you can restore the warranty but only by downgrading to the stock ROM or by updating with an official firmware released by Samsung and suitable with your Galaxy Tab 2.

Up next download and install a custom recovery image (like CWM recovery) on your device. After that ensure that you are having access to a Windows running computer, uninstall the security programs (antivirus and Firewall protection enabled) and enable the USB debugging option on your tablet. Also, you need to make sure that the Tab has enough battery life for staying “alive” during the update process. For that check the battery status and if there is less than 60% power left go and charge the battery. Remember that the Android 4.2 Jelly Bean based CM 10.1 preview build is working only for the WiFi Samsung Galaxy Tab 2 7.0 so don’t try to update another device with the same software.
