Google's flagship tablet Nexus 7 has received its first official MIUI ROM based Jelly Bean update on the second anniversary of MIUI, thanks to the team and community of MIUI Android. Sporting a fresh and vigorous look with its interface design, the official MIUI ROM provides a unique experience to users in contrast to other custom ROMs for Jelly Bean update.
The ROM also ports a rich feature set including integrated themes support (with access to hundreds of fan-made themes), privacy and security features, call optimisation and SMS features, and so on. Discerning users craving for a break from the regular custom ROMs could embrace the MIUI ROM for a welcome change. This is a very stable release considering that the ROM is an official version.

How to Install Official MIUI ROM Based Jelly Bean Update on Google Nexus 7
1. Download the latest version of the official MIUI ROM from here. Look for the "grouper" version of MIUI under the 4.1.x heading and download it (see screenshot below):

3. Power off the tablet and boot into recovery through a button sequence. Press and hold the Volume Up, Volume Down and Power buttons together until the device boots into CWM recovery.

5. Tap wipe data/factory reset, then choose Yes to confirm on next screen. Wait until the data wipe process completes.
6. Choose install zip from sdcard, and then tap choose zip from sdcard. Locate the ROM file on the SD card and select it. Confirm installation by choosing Yes on the next screen. The ROM should begin installing.
