I love to try new stuffs. Just managed to install Team Win Recovery Project ~ TWRP 2.0 on my Amazon Kindle Fire. And managed to install CM7 ROM on Kindle Fire too. Play around with TWRP 2.0 Recovery. Backup Kindle Fire stock ROM. Wiping data… And I did one thing that I think it might cause issue. And it did. Selected reboot into recovery in CM7. As a result, my Kindle Fire keep boot into TWRP 2.0 Recovery even without pressing power button. In short, bootmode was set to recovery 5001 by default. So you need to change it back to normal 4000 bootmode.
