Almost Bricked Kindle Fire HD 6 4th Generation

Now that I have successfully corrupted my tablet, e.g. I can't uninstall some apps and I cannot seem to open Google Play.
The only thing that is different is that I now have Linux running in chroot.
My solution is to start over.
Luckily I can still adb recovery boot into TWRP, because I am still on the 4.5.3 version of the software.
First, I download a newer Amazon OS on to the tablet. I found download links on XDA. In fact you can stop reading now and try to follow the XDA instructions.
Anyway here is what I did:

Downloaded the Amazon OS file to my PC and renamed it from .bin to .zip (this is done by disabling hide extensions in the file manager).

Connect Fire HD 6 to the PC and type "adb reboot recovery".

Copy the renamed .zip file to Downloads.

Choose install in TWRP and select the .zip file.

If all goes well, you will probably end up with the new OS and UI, but no recovery program as TWRP was overwritten.

Find and download the 5.2.0_stock_recovery_uboot.zip to your tablet.

Find, download and install Flashify. (Google Play version for reference)

Start Flashify and flash the stock recovery file.

An "adb reboot recovery" revealed that a recovery program is still not available.

I choose to skip loading a recovery and root the tablet via KingRoot. Be patient and try several times.

Once rooted, you can research your self on how to install a recovery program and Google Play.

I opted just to install Google Play.

Look for my next post, which will likely be called Corrupted the Kindle Fire HD 6 4th Generation (AGAIN!). BTW I am doing all this because I essentially got the new 16 GB tablet for $40 off Amazon.

Oops, I almost forgot that I need to turn off automatic updates. Here's a how-to on YouTube.
