The Asus Google Nexus 7 is currently powered by the Android 4.2.2 Jelly Bean OS and while most of its users are willing to stick to the stock and pure Jelly Bean system, there are also some that will rather choose to customize and optimize the Nexus 7 OS. If that’s your case too, then do consider in updating your Google Nexus 7 with the latest release of CM10.1 custom ROM, the RC5 JB 4.2.2 firmware. Apply the next steps for learning how to prepare your tablet for the installation procedure and also for checking how to properly complete the flashing operation.
CM10.1 RC5 is already available for the Galaxy S3 model numbers T999, L710, I535, I747 as well as for other Android based handsets, and now the CM team has added the Asus Nexus 7 in its supported list of devices. The ROM is based on stock Jelly Bean 4.2.2 OS, but you will not receive the classic Android experience on your tablet. By flashing the CM10.1 RC5 software on your Google Nexus 7 you will actually install a custom version of the Android system that comes with its own features, apps, capabilities and looks.
Furthermore, the CM10.1 platform is customized and optimized meaning that you will be able to gain more speed from your Nexus 7, improve the battery life, access the internal system, remove in built programs, install complex apps, personalize the looks and so on. The CM10.1 RC5 ROM is stable, comes without bugs and issues and according to those who have already applied the OS, the same is smoothly running on the Google Nexus 7.
But for being able to receive all that you first have to complete this guide; and since this is a complex, risky and unofficial procedure you need to learn how to prepare your tablet for the installation procedure that will follow. So, read the next lines (you can also learn further aspects related to the present process – installing a custom ROM) and apply the tasks described below.
- CM10.1 RC5 is not an official or stock Jelly Bean 4.2.2 OS; the ROM has been developed by third party devs and represents a free aftermarket distribution of the Android system.
- Therefore, this tutorial has nothing to do with Asus or Google; you will update your Nexus 7 with an unofficial port of the JB 4.2.2 firmware.
- That’s why you previously need to root your tablet; else you won’t be able to apply the CM software.
- Unfortunately by gaining root access, the warranty will also get void; if something bad happens you will be by yourselves – we shouldn’t be held responsible though.
- You can restore the warranty by downgrading / updating to stock / official Android OS; then the root access will be revoked and the bootloader relocked.
- You need to replace the stock recovery with a custom one, so install a custom recovery tool, like CWM recovery on your Nexus 7 – the same will be used on the flashing operation so don’t skip this step.
- It is important to backup your data because a wipe will also be required. As you will see below, before installing the CM10.1 RC5 software, you will have to clear the cache and wipe the system of your Google Nexus 7; therefore save everything you might need as it is quote probable to lose your personal info, accounts and data.
- Make sure that you can use a computer or notebook, your tablet and the USB cable; preferable, on the computer and handset there shouldn’t be running any security program – uninstall or deactivate the antivirus, antimalware and Firewall protection.
- Enable the USB debugging option on your tablet and also charge your device if there is less than 60% power left (if not you can skip this part; be careful though as if the tablet gets turned off while you are trying to update its system, the device might get bricked).
- This tutorial is compatible only with the 3G version of the Google Nexus 7, so be careful in what you do and try not to mess things up; don’t use the next steps if you want to install the CM10.1 RC5 ROM on a different or similar Android based device.
