[BOOT] FIREFIREFIRE 1.3 - Replacement bootloader w/ recovery selection
FIREFIREFIRE is a replacement bootloader originally created by pokey9000 for the Kindle Fire. While the stock bootloader simply boots into the system, FIREFIREFIRE provides an option to boot into recovery and also enables fastboot for a short period of time. Everyone from developers to users of alternative ROMs will certainly benefit from having FIREFIREFIRE on their device.
Recovery Selection - As the Kindle Fire boots up, the power button LED will change from bright green to a dim green. Once it changes to a dim green, press the power button again and release (repeat a few times to be sure). The LED will then change to an orange color indicating recovery selection and boot into recovery.
Enable Fastboot - As described above, when the power button LED changes to a dim green, the Kindle Fire will enter fastboot mode for approximately 4-5 seconds. During this time, fastboot commands can be issued and the device will remain in fastboot until it is rebooted.
Write Partition Tables - During fastboot, issuing a 'fastboot oem format' command will overwrite the existing partition table with the stock table values.

0.9 - 1.2
I originally just wanted to rebuild the FIREFIREFIRE bootloader to bake in a custom boot logo for my own use. That opened the door enough for me to become interested in making some minor improvements in how it handles recovery selection. When I contacted pokey9000, he encouraged me to work on it and gave me enough confidence to begin studying the code. Although I couldn't begin to estimate a timeframe, I hope to continue working on it and build in some enhancements that would be worthy of eventually calling it version 2.0.
The bootloader is possibly the most underappreciated piece of software on the Kindle Fire. It's not overreaching to say that everything else is built on top of this foundation. Without the work of pokey9000, the XDA Kindle Fire community would not have gotten the other great developments as quickly as it did. When the next great device comes along, we will certainly need the work of talented people like pokey9000 again.

A special thanks to smirkis for having the guts to be the first in line to flash my build on his device.
