Returning to stock ROM on the Amazon Kindle Fire is very easy. Once you’ve gotten root access and installed TWRP Recovery, you can easily flash the stock ROM from the TWRP and turn in your device for the warranty purpose. If you’ve messed up with your device or just want to unroot it, here’s how you can do it. The following guide shows how you can unroot your Amazon Kindle Fire. Here you go:
1. You should have rooted your Kindle Fire using the guide given here.
2. You must have TWRP Recovery installed on your device. You can do so from here.
3. The battery level on your device shouldn’t be less than 60%.
1. Stock ROM (Download link’s given in the first post of the thread)
1. Download and place both the files you downloaded to the Desktop.
2. Extract files from the Fastboot archive to your Desktop.
3. Rename the Stock ROM file you just downloaded to update.zip.
4. Enable USB debugging on your device from Menu>>Settings>>Applications>>Development>>USB debugging.
5. Connect the device to your PC using the USB cable.
6. Copy the Stock ROM file over to the root folder of your device’s SD card.

adb reboot recovery
9. Your device should reboot into the Recovery Mode from where you can flash the stock ROM.
