Use kffa to install the Google store or kindlefree. Just curious, what were you planning to do by installing twrp and keeping stock amazon os? You just want a method to easily recover from a brick or were you thinking of flashing a ROM at some point?

Once you install the drivers, shut it off and unplug it, you will need to open a command prompt that's cd'd into a directory like kffa where you can run a fastboot command. Then run

Code:
fastboot -i 0x1949 getvar product
it should say waiting for device, once it does plug your kindle in, it should go into fastboot mode and you can restore with kffa.

Hello,

I have the exact same problem as the original poster with my Kindle Fire HD 8.9". I tried downloading the drivers in your description. I connect the kindle and try to update the drivers for Jem-PVT-Prod-04. I direct my computer to install the drivers that I extracted, however it returns an error saying that "the hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering." I'm not sure what I'm doing wrong, this is my first time trying to root android. Thanks so much for the help!

You need to disable driver signature enforcement. Look it up on Google, I don't know the procedure offhand because I don't use windows 8.

Hello. I know this thread is old but I just stumbled across it and want to restore my mom's Kindle HD 8.9. I was able to install the drivers for Jem-PVT-Prod-04 when it showed really quick on the device manager. When I try the CMD "fastboot -i 0x1949 getvar product" from the command prompt it takes me to the desktop folder where the Zip file is located and I had already unzipped the KFHD_SRTv2.1- 8.1.4.

I tried running the SR Tool and my Kindle was off. I had selected Enable Fastboot. When it prompted me to turn on I did and it prompted DAEMON. So nothing was going on So I decided to start from the beginning.

When I plug in the Kindle Windows 10 prompts like it recognizes the device but the JEM PVT is no longer popping up in the Device Manager under OTHER Devices like the first time. I checked the Registry to remove any trace of the JEM and it isn't even in there. I tried to remove other devices.

Sorry for the long story. Can I just use the SR Tool to wipe out the Data and Cache once I redo everything from my second PC and install the Kindle OS from Amazon's website to restore the Device from the loop? It is not blue. Is there another link with step by step instructions or a You Tube Video for noob like me? I used to be good at this but my skills have really regressed.

Thank you

Frank
