If you have decided to go further with this tutorial, then here is what you need to do; I will detail the preparation tasks, so you mustn’t skip this section as it is the most relevant one. If you do skip it and head straight to the proper steps from below, then you will risk in bricking your Nexus 7 tablet. Therefore, be careful in what you do and always follow my directions, don’t perform things by yourselves.

  • First of all I recommend you to backup the data which is being saved on your device.
  • You can use SMS backup and restore tools for saving the text messages.
  • You can sync with Google for backing up the contacts and more.
  • Save the internet setting and use a computer for saving files like images or videos.
  • If your Nexus 7 is running a custom recovery image, then you can use the same for backing up the current ROM.
  • As soon as you end the backup, you should go and root the Asus Nexus 7. Without rooting you will not be able to install the CM10 based Jelly Bean 4.1.2 Glazed Custom ROM. Also, as a final note, be aware as by rooting the warranty gets void and the only way available for restoring it is by making a downgrade, or by updating with an official OS provided by Asus and suitable with your tablet.
  • After unchaining the system, you should also install a custom recovery image, such as CWM recovery, on your handset. This tool will be used for applying the update, so it’s extremely important to get CWM recovery.
  • Now, a computer or notebook should be near you. On the same as well as for your Nexus, there shouldn’t be installed any security programs, so deactivate the antivirus and Firewall protection.
  • Enable the USB debugging option on your handset and charge its battery or else it might get turned off in the middle of the operation.
  • Install the CM10 Glazed Android 4.1.2 update only for the Google Nexus 7 and not on similar devices as you can end up in bricking your gadget.

So, now you know everything about the present update and not to mention that your handset has been prepared for the proper update procedure. This means that you can finally head to the next section of this tutorial:
