For those have been waiting for Android 4.1 Jelly Bean update on Kindle Fire, we have some good news. The new update has been ported to the slate just a few minutes ago, and should be smooth as it’s expected. The new Amazon Kindle Fire Jelly Bean update comes as beta port thanks to the always helpful XDA-developers coders.
The new Android 4.1 Jelly Bean update for Kindle Fire tablet is based off of the recently-released Jelly Bean AOSP source code.
The Kindle Fire Jelly Bean ROM, however, does quite well supporting all of the tablet’s hardware, except for the HD codecs decoder for YouTube and Netflix videos.
If you’re curious to get the new Kindle Fire JB update all you have to do is flash in recovery, wipe data/cache and reboot. Naturally, you’ll need to have your device rooted and loaded with a custom recovery to get things, and then flash the provided ROM and Google Apps package. You would also need to use ADB to enable the wireless connectivity.
Though there are few bugs included in the update, fixes are assuredly on the way, so the less carefree might want to abstain from flashing at the moment.
Update: You can grab the download files via source link below, though Hashcode appears to have linked the wrong version of Google Apps in his guide — they work just fine if you use this version instead.
