The Amazon Kindle Fire HD has been an enigma for developers. Its bootloader was completely locked down, and many claimed it was unhackable. Low and behold, developers still managed to attain root anyway. Of course, that’s only part of the process. Now, the next step has occurred, and Kindle Fire HD owners can now have a custom recovery.
XDA Recognized Developer Hashcode has released Safestrap for the Kindle Fire HD. It’s capable of giving the newest Kindle a custom recovery. If you’re a little fuzzy on how Safestrap works, Hashcode explains:
Safestrap is a Bootstrap / Recovery for locked bootloader phones. The goal is to avoid touching your primary system (I’ll call this “stock” system) and only flash or make large changes to another place on your phone that Safestrap treats as a “2nd system” (in this case, it’s a series of virtual ROM slots located on the internal emmc area: “/sdcard”).
Installing it is easy, but Hashcode does warn that this is a serious hack and can resolve in soft bricks. As per the norm, proceed at your own risk. Despite the risks involved, this is an amazing development for Kindle Fire HD users, as the unhackable bootloader continuous to be less of a problem than it once was.
