I just need a tester for a small idea i have for installing twrp recovery and 2nd bootloader in a safer manner than usual. The other manners are pretty safe but i figured this seemed really safe because its so simplistic in nature. I don't know whether i will continue this project depending on the results of the test, but basically i thought why not make a 2nd init/bootstrapped twrp that runs a ota update on a zip file that just installs everything for you with a conveniently placed zip file with asserts that it checks for then deletes itself. My first test is just for a 2012 kfhd 7" that either has no 2nd bootloader + twrp and a fastboot cable handy to restore in case this soft bricks it or one with a version of twrp already installed that it higher than 2.6.0.0. I don't wanna post the actual file because i don't want accidental bricks. Chances are based on how this works it will probably brick the first time around because i have not messed with the hijack scripts to mount everything properly yet, but this was taken from another omap based device so if it doesn't work i don't think it will take too much tweaking, but the initial binary it tries to run may cause some havok. I can assure you this should be easy to restore from in twrp by simply renaming a system file, otherwise without a copy of twrp already installed you will have to restore with kffa. I need the kindle that this is being tested on to also be on a rooted amazon os, not another rom. I have no idea if twrp will work with amazon's stock kernel so this should be interesting. post back if you are interested.
If you are wondering why i didn't decide to test this on my own first its simply because i don't feel like having to wipe my entire data partition and restore the data from my pc just to clear selinux xattribs off my data partition so that amazon's kernel will not throw a fit.
So overview for those that don't want to read that big paragraph:
Requirements:
-Running Amazon OS with root
-Have a way to recover from brick (2nd bootloader + twrp or flash back with kffa/srt) - twrp preferred but plz have a never version than 2.6.0.0 installed.
-Have busybox installed
