How to Install AOSP Based Android 4.1 Jelly Bean on Google Nexus 7

Step 1: Before installing the AOSP custom ROM, you need to unlock the bootloader on your Nexus 7 by using the Nexus Root Toolkit (Download here). It must be noted that this step will wipe all the data on the tablet including the files on the SD card. So, it is imperative to take a backup.

Step 2: Install ClockworkMod (CWM) recovery on the tablet by following the guide posted here. Install the touch version of recovery as it is more convenient to use.

Step 3: Download the latest version of the AOSP custom ROM from the official development page.

Step 4: Copy the zip file downloaded in step 3 to the root folder of the SD card on the tablet (do not extract the files).

Step 5: Now, boot into recovery by performing a button sequence. Power off the tablet. Then, press and hold the Volume Up + Volume Down + Power buttons together until the device boots into CWM recovery.

Step 6: Take a Nandroid Backup of your existing ROM. So that you can revert back or restore your older ROM, if something goes wrong with this ROM. To perform a backup, select Backup and Restore; on the next screen, choose Backup again. Return to main recovery menu once backup is done.

Step 7: Tap wipe data/factory reset, then choose Yes to confirm on the next screen. Wait until the data wipe completes.

Step 8: Select install zip from sdcard, then tap choose zip from sdcard. Locate the ROM file on the SD card and select it. Confirm installation by selecting Yes - Install _____.zip on the next screen. The ROM should begin installing showing the progress bar.

Step 9: Once the installation completes, return to the main recovery menu and hit reboot system now to reboot the tablet into Liquid Jelly Bean ROM. The first boot usually consumes time and it may take up to 5 minutes.

Step 10: In case you want to return to your previous ROM, boot into recovery (as given in step 5), choose backup and restore. Then restore your previous ROM by selecting it from the list.

This completes the installation process for Liquid Jelly Bean on your Nexus 7. You can now enjoy the goodness of Liquid jelly Bean with butter smooth performance and improved customisation capability.
