Your Galaxy Nexus 7 Wi-Fi 2013 model can now run the latest CM 11 Nightly build and you can use this post in order to learn how to successfully update your device.
Official CM 11 Nightly is based on Android 4.4 KitKat soon to be updated to Android 4.4.2 and it packs all stock KitKat features along with multiple other CyanogenMod ones. More info about this release can be found at the developer’s web page here. Learn how to flash this new custom ROM and read the guidelines below before starting the process:
- use this post only with the 2013 Nexus 7 Wi-Fi model with the codename set to ‘flo’.
– don’t use this post for any other Android tablets or smartphones.
- your tablet has to be rooted and running the latest CWM or TWRP Recovery image.
– we’re not sure if TWRP will work, but you still need to update it to its latest version.
– you’ll find instructions for both custom Recovery versions in the tutorial.
- ‘factory reset’ is required for this new ROM to install correctly.
– don’t skip this step, unless your device already uses a previous CM 11 Nightly official release.
– factory reset wipes all data from system partition, while the internal storage won’t be affected by this process.
- it is highly important that you create a full NANDROID ROM Backup for the OS that is currently installed on your device.
– this restore point will allow you to repair your device in case the new ROM doesn’t boot in normal mode.
– the step is listed in the tutorial and you shouldn’t skip it.
- if you want to backup data from installed applications then you can use Helium — Google Play Store link here.
- enable USB debugging from Developer Options menu.
- check the device’s battery power level and make sure that it is over 50%, so that the tablet won’t switch off in the middle of the installation process.
- read the entire post first, don’t skip any steps and you should be OK.
- in case you cannot complete the tutorial, then you should ask for more help in comments.
- do not blame us in case you brick the device or lose any important data in the process.
Now that you know all of the above, continue to the next part of this post and learn how to update your tablet.
- Download the custom ROM zip from here.
– make sure to grab the latest build available and not an older one.
- Download Gapps Android 4.4 zip from here.
- Connect the tablet to your PC, then move both zip files to its internal storage.
– after the files are copied, disconnect your tablet from your computer.
> don’t unzip the files.
- Power off the tablet.
- Now boot the Nexus 7 2013 in CWM / TWRP Recovery.
– remember that the custom Recovery should be updated to its latest version possible, so that it will be able to flash Android 4.4 ROMs.
- First, create a full NANDROID ROM Backup:
– CWM: select ‘backup and restore’, name the file and save it to internal storage.
– TWRP: press Backup, swipe to confirm the process.
> don’t skip this step.
- Next, apply the ‘factory reset’:
– CWM: select ‘wipe data/ factory reset’, confirm.
– TWRP: press Wipe, then swipe to confirm that you wish to factory reset the device.
> don’t skip this step unless your device already runs on a previous CM 11 Nightly ROM>
> if you skip ‘factory reset’ and the Nexus 7 doesn’t boot in normal mode, then you will be forced to repeat the entire tutorial afterwards/
- Now that you’ve reached this post you can start installing the new custom KitKat ROM:
– CWM: select ‘install zip from sdcard’, then ‘choose zip from sdcard’ and find the CM 11 Nightly ROM zip file. Confirm.
– for TWRP you need to press on Install, browse the internal storage for the CM 11 Nightly zip, then swipe to confirm installation.
> do not press any buttons until the process is complete.
- Flash the Gapps zip after the new ROM is installed:
– CWM: select ‘choose zip from sdcard’ once again, find the Gapps file and confirm the process.
– TWRP: press Install, find Gapps zip, confirm the process.
- When both files are installed, get back to the main custom Recovery screen.
– CWM: select ‘reboot system now’.
– TWRP: press Reboot, then System.
> now you have to wait until CM 11 Nightly completes the first boot process, don’t press any buttons.
- Enter your CyanogenMod / Google account details and take control over your tablet when the home screen of your device appears.
– now you can start testing and customizing the entire UI of your new CM 11 ROM.
I hope that you did manage to complete the installation of CyanogenMod 11 Nightly KitKat custom ROM on your Google Nexus 7 2013. If you encounter any problems when installing this ROM, then you should ask for more help in comments by making sure that you give a detailed report of all the actions you took until you got stuck.
NOTE: if the first boot process of CM 11 Nightly gets stuck at the CyanogenMod boot animation screen for more than ten minutes, or in case the tablet enters into a boot loop, then you will be forced to repeat the entire tutorial once again. If you decide to repeat the installation, then it would be best for you to read these guidelines:
- do not skip the ‘wipe data/ factory reset’ step.
- also, make sure to ‘format /system’ as well after ‘factory reset’.
- try to flash the ROM without Gapps, then you need to reboot in Recovery and flash Gapps.
- if you re-install the ROM, but not Gapps and the system boot normally, then you flash Gapps and the tablet doesn’t boot, then you will be forced to flash a different Gapps file. (info here)
I think that these are all the instructions that I had for you, now you’re free to test the new ROM.
In case you don’t like this new CM 11 Nightly ROM or your tablet struggles to run it smoothly, it shows one too many errors, then you should restore the device to its previous ROM.
