Let’s see how to install the Nexus specific CyanogenMod 11 M1 on your Nexus 7 2012 (GSM).

WARNING!

Warranty may be void of your device if you follow the procedures given on this page.

You only are responsible for your device. We won’t be liable if any damage occurs to your device and/or its components.

CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be NEXUS7C!

Do not use the procedures discussed here on any other Nexus device or any other company. You have been warned!

BEFORE YOU BEGIN..

You must do this pre-installation stuff before attempting to install the ROM on your Nexus 7 2012  in order to avoid any complications later, and have a smooth and successful process.

BACK UP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

For help on Backup and Restore, check out our exclusive page on that linked right below.

CHARGE YOUR DEVICE

If your android device powers off due to lack of battery while the process is underway, it could damage the device.

So, make sure your device is adequately charged — at least 50% battery of the device.

EXAMPLE VIDEO

If you haven’t used a custom recovery, either CWM or TWRP, before, to install a .zip file of a ROM on anything else, then we suggest you first watch a video of that, given right below, to get familiar with the process.

Just fyi, the video below shows installing a .zip file (of recovery) on Galaxy S3, but it doesn’t matter as the process remains exactly same. So, once you are finished with video, jump to downloads and step-by-step guide below.

Reminder: Before you proceed, make sure you’ve transferred the files you downloaded above to a separate folder on your Google Nexus 7C.

STEP-BY-STEP GUIDE

Make sure you have backed up your tablet adequately (including important data stored on internal memory).

NOTE:

Older versions of both CWM and TWRP recoveries are not working with Android 4.4 based ROMs, throwing installation errors and even WiFi bugs on some tablets, therefore you need to use the latest version of either recovery. We believe TWRP v2.6.3.0 and above, and CWM v6.0.4.3 and above are working fine with Android 4.4 ROMs.

You need unlocked bootloader and a custom recovery to be able to install CyanogenMod 11 M1 on your Nexus 7C. Get help from the toolkit given here.

Using toolkit, you can do all the stuff: unlock bootloader, install a ClockworkMod recovery, etc.
