Update Nexus 7 3G to CyanogenMod 10.1 RC5 Jelly Bean 4.2.2 custom ROM

The smartphone we want to install CM10.1 RC5 today is Nexus 7 3G. There seems to be a shortage on tutorials on this matter, so we decided to step in and lend a helping hand. Especially if you own this model.

The developers which created the CyanogenMod, or CM in short, have been working hard on a tool to use on the Nexus 7 3G. When they came with the CyanogenMod 10.1 RC5, it was decided that it would fit that device perfectly. And it does, because we tested it ourselves not too long ago.

Once the guide here is over, your tablet is going to display an improved performance. Not that it behaved badly in the past, but it shall be faster, much more stabler and so on. The features that come with this tool are based on what Android 4.2.2 JB delivers.


The flashing of the CM10.1 RC5 may end up in a damaged Nexus 7 3G. To avoid that, follow our tutorial’s steps accordingly. And first observe these pre-requisites:

How to flash CM10.1 RC10 JB 4.2.2 on Nexus 7

  4. To enter the device in the Mode you need, press and hold Volume Up, Home and Power at the same time; the display of the tablet will flash soon, so you need to stop pressing and holding those keys and instead focus on making a NANDroid backup next; this sort of an operation should be performed by taking the following route: choose Backup & Restore, opt for Backup and wait for the process to start and then to finish.
