For the past weeks, more and more devices have been showered with Android 4.1 Jelly Bean goodness through official releases and custom ROMs. This time around, the Amazon Kindle Fire gets to taste features of Jelly Bean through a custom ROM released by XDA Developers member Hashcode.

Just like other custom ROMs that are still in the early stages of their build, this custom ROM still has bugs and issues. Among several other issues, one issue often complained about is that Mass Storage is the fixed default when mounting the SD card.

If you want to upgrade the Kindle Fire to Android 4.1.1 Jelly Bean by installing this custom ROM, follow our requirements and easy-to-follow instructions below.
