In a much encouraging move for developers who had been waiting to try their hands on the latest version of the Android operating system, Android 4.1 Jelly Bean, Google released the source code of the OS earlier this week in the Android Open Source Project (AOSP), allowing developers to dabble with the new software. And now, thanks to an AOSP-based Jelly Bean (4.1.1) ROM, you can install the OS on your Amazon Kindle Fire tablet.

A member at XDA Developers named Hashcode shared the way of installing Jelly Bean on the Amazon tablet. However, the ROM is currently at its beta stage, meaning that it does include some imperfections. The forum post noted that there were issues with the HD codecs, affecting the use of YouTube and Netflix. But with Texas Instruments updating the libion code for Jelly Bean, Hashcode said he would be fixing the issue soon.

Apart from the codec problem, the screen seems to be over-rotating while changing position. In addition, turning on UMS in the ROM also seems to be a bit difficult.

The Android 4.1 source code was released in the AOSP under the name android-4.1.1_r1 for everyone to download, examine, and likely attempt to port a whole host of devices.

We're releasing Android 4.1 in AOSP today. The name of the tagged release is android-4.1.1_r1, Google's Jean-Baptiste Queru wrote in the Android Building Group. The name of the development branch is jb-dev. We recommend that you create new clients, even if you're working in the master branch. It'll make your clients smaller and faster to sync.

Given below are the steps to follow for a manual installation of the beta release of Jelly Bean (4.1.1_r1) on the Kindle Fire (Courtesy Redmond Pie).

Before going ahead, please note that IBTimes will not be held responsible if any user loses data or the device gets damaged while following the steps explained below. Users must proceed at their own risk.

Step 1: Download the Android Jelly Bean 4.1.1 ROM for your Kindle Fire. It's around 108MB of size.

Step 2: Download Jelly Bean Gapps, which you need to flash onto your device.

Step 3: Power down your device and boot into recovery.

Step 4: Flash the ROM/Gapps you've already downloaded in the first two steps from ClockworkMod Recovery. Make sure you do a complete wipe of the data and cache.

Warning: This will delete your personal data. Therefore, you should make sure that everything is backed up.

Step 5: Now restart your device from CWM and your Kindle Fire should now be running Android Jelly Bean 4.1.1.

In case you cannot connect to Wi-Fi after flashing, you'll have to adb shell su and you should be good to go.
