Asus Nexus 7 Android 4.1.1 Jelly Bean Manually Update

If you happen to be lucky enough to own a Nexus 7 then you’ve undoubtedly heard that as of yesterday the device began to receive an update to its OS. This update is the 4.1.1 version of Jelly Bean and it brings with it a fair amount of optimization and performance enhancing tweaks.

Many of the small bugs that were found in the original version of Jelly Bean on the Nexus 7 have also been ironed out and with Android 4.1.1 all HD games should run smoothly and there should be no more battery or display issues either. Also, Google Wallet is reportedly included in this new release as well.
Needless to say, if you haven’t already updated your Nexus 7 to 4.1.1 then you’re going to want to do so as soon as possible. Unfortunately the bad news is that Google is rolling out this update in stages, and so if you happen to be in a country where the update isn’t out yet you are going to have two options: Either you can wait until the eventual roll out does reach your country, or you can manually update your Nexus 7.
Prerequisites
Before you attempt to manually update your Nexus 7 with Android 4.1.1 Jelly Bean, you’ll need to make sure that it fulfills the following prerequisites:

• The Nexus 7 tablet needs to be rooted
• At least 60% of the battery charge must be remaining
• All important data should be backed up beforehand. Sync your contacts with GMail and transfer all files to an external SD card or some other storage if possible

Due to the fact that you are going to be installing the update via the Recovery Mode, you can use a custom mod like ClockworkMod recovery – but it is not necessary. If you are using the stock Recovery Mode this installation process will work just the same.
Installation Instructions
To manually install the Android 4.1.1 Jelly Bean update, all that you need to do is follow these instructions:

1. Download the Android 4.1.1 Jelly Bean Update Package from the link provided and save it on your computer
2. Use a USB cable to connect your computer to your Nexus 7 device
3. Transfer the file that you downloaded to your Nexus 7
4. Disconnect the USB cable and turn the Nexus 7 off
5. Enter recovery mode by holding down the volume down and volume up buttons while pressing the power button simultaneously
6. Select the option: Install ZIP from SD card
7. Select the option: Choose ZIP from SD card
8. Browse, locate, and select the file that you downloaded and transferred over in Steps 1 through to 3
9. Wait for the update to finish installing and then select the option to ‘Reboot System Now’

Once your Nexus 7 reboots, it should already be running on Android 4.1.1 Jelly Bean. If you’d like to check, you can head over to the ‘About Tablet’ section of your ‘Settings’ and the Android version should be displayed there as 4.1.1.
Installing this update really isn’t all that difficult, and considering the improvements made in Android 4.1.1 it makes sense that you’d want it sooner rather than later. So long as you follow these steps, you should have no issues with the manual installation.
