1) Download fireos 188.8.131.52 last version from amazon official site.
2) Rename .bin to .zip
3) Put into root (sdcard) on fire
4) Boot into twrp recovery, install said zip
5) Done??? (I assume the one zip will install to the 3 partitions (.img) on the fire?
I followed the instructions, unlocked my bootloader, and installed custom rom. No problem. Problem is, I didn't make a stock fireos backup first. The real kicker, I advanced wiped everything in twrp before the custom rom. Now it seems I have nothing but twrp and my custom rom.
NOT ACTUALLY WANTING STOCK OS BACK, but I didn't root at the time of the custom rom install. I didn't care about root at the time, just the custom rom. But now I DO want root, but kingroot etc won't work now. I assume it only works with the stock install? Because I'm now on aospextended, it appears I'm on a Kindle Fire 7" on android 7.1.2
Any suggestions on how to simply get root now at the current condition my hdx is in now? Thanks alot, been coming here for a long time. I'm usually the type to just "try and see" and not really ask many questions, but man I don't wanna brick this and I know how touchy these can be.
