Yeah… I just ‘brick’ my Amazon Kindle Fire again after faced boot loop issue on Kindle Fire TWRP 2.0. Kindle Fire stuck at yellow triangle screen this time after install TRWP with Kindle Fire Utility. And adb cannot detect any device. But my Kindle Fire is still able to be detected at Windows as Android ADB Interface. So I know that it is not actually brick. Look around the Kindle Fire Utility run batch file. Found out that my Kindle Fire is on Fastboot mode ~ yellow triangle screen.
