The official version of CyanongenMod10.1 Release Candidate 2 is now available for the Google Nexus 7 WiFi Edition. Use this tutorial and you will learn how to successfully flash this custom ROM on your tablet device. Read the entire post and only update your tablet when you’re sure that you know what you’re doing.
If you wish to flash the CM 10.1 RC2 build for your Nexus 7 WiFi, first you will have to read these guideline:
- this is a guide that works exclusively with the Google Nexus 7 Wi-Fi variant. Don’t try to flash this official build of CM on any other Android device.
- your tablet has to be on unlocked bootloader, rooted and running a custom Recovery image like CWM or TWRP. I’ve used the ClockworkMod Recovery for this guide, but you can also use the TWRP version, as the instructions for it are very similar and it will work.
- use the custom Recovery image to create a full NANDROID backup of your current ROM. This will set a restore point that can be used in case your device is unable to boot with the new ROM.
- backup the files you consider to be the most important.
- the tutorial will ask for ‘factory reset’ and this means that the /system partition of the tablet will be wiped in the process. The internal SDcard contents won’t be affected by this process.
- enable USB Debugging from the Developer Options menu.
- make sure that the Nexus 7 battery has at least 50% power left in its battery. This will prevent the device from powering off in the middle of the updating process.
- use this tutorial only if you are an Android user who knows how to complete the steps listed below.
- make sure to complete all the steps listed in the tutorial.
- in case you’re having trouble installing the new ROM, then you should ask for extra help in comments.
These were the extra instructions that you had to go over before continuing to the next part of this guide.
NOTE: in case your device is already running on a previous build of CM 10.1, then you can skip the ‘factory reset’ and perform a ‘dirty flash’ by installing the new CM 10.1 RC2 ROM over the previous CyanogenMod build. If your tablet doesn’t want to boot with the new ROM, then you will be forced to repeat the entire tutorial and factory reset its OS, as that might be why the phone isn’t capable of booting.
How to install CM 10.1 RC2 Jelly Bean 4.2.2 ROM for the Google Nexus 7 WiFi:
- Download the CyanogenMod zip file from HERE. Don’t unzip, save the file on PC.
- Download Gapps for Android 4.2.2 JB ROMs from HERE. Save it on your computer and don’t extract its contents.
- Connect the tablet to your PC using the USB cable. Now move both files onto its internal SDcard.
- Disconnect the tablet from your PC.
- Power off the Nexus 7.
- Boot it into CWM Recovery mode by pressing and holding Volume Up, Volume Down and Power buttons. When in custom Recovery mode get to the next step.
- Select ‘backup and restore’ option from the main recovery screen. Create a NANDROID backup of your currently installed OS. This will set a restore point for the tablet and it can be used in case you’re having problems with the new ROM.
- Select ‘wipe data/ factory reset’ and confirm. NOTE: if the tablet already sports a previous build of CM 10.1, then you can skip this step.
- Select ‘install zip from sdcard’, then ‘choose zip from sdcard’ option. Find the CM 10.1.0 RC2 build and confirm its installation. This process should take several minutes to complete.
- After the ROM is installed, select ‘choose zip from sdcard’ again. Find the Gapps zip and install this one now.
- After both zips have been successfully installed, you should return to the first screen of CWM Recovery mode.
- Select ‘reboot system now’.
- The first boot process of CyanogenMod 10.1 RC2 shouldn’t take more than 7 minutes to complete. Wait for all file to be loaded and then take control over your tablet by entering your Google Account details.
- Test and customize all areas of CM 10.1 Release Candidate 2 Jelly Bean ROM. Tell us in comments which are your favorite functions.
I think that these were all the steps you had to take.
If the new ROM doesn’t or the phone enters a boot loop, then you will have to power off the tablet completely. After that, you need to repeat the entire tutorial once again and re-install the CM 10.1.o RC2 ROM. If you do reinstall the custom ROM, then you should make sure that you successfully apply the actions listed under step 8 and factory reset the tablet before flashing the ROM files.
If you cannot complete the installation then you can ask for more help in comments.
