These are the steps it took for me to update back to 5.8.1, it might be different for you. The goal is to have "Update Your Kindle" tappable.

1. You can turn Airplane mode off now.
2. Go to Home > Menu > Settings > Menu > Device Info
3. You should receive a message about an update being available. Go ahead and apply it.
4. After that, go back into Device Info like three times until the "Update Your Kindle" is tappable.
5. Tap "Update Your Kindle" and allow it to finish.

F) Install KUAL and MRPI

1. Follow the instructions in the KAUL thread
2. Follow the instructions in the MRPI thread

Done!
