TWRP Recovery is the world’s best custom recovery at the moment thanks to the built-in file manager that can manage files both from your internal and external SD cards. It’s also got the adeptness to boot from the Android operating system to the custom recovery and to the bootloader mode or download mode. Additionally, you can take full backups with the NANDroid Backup and even give those backups a name, a date and time stamp, and label the name of the current ROM. Those are just a few examples why TWRP Recovery is currently leading the way.

These are the instructions to install TWRP Recovery 3.0.0 on Amazon Kindle Fire HDX:

REQUIREMENTS

• The following guide is made for the Amazon Kindle Fire HDX only and will install the latest TWRP 3.0. Do not use the TWRP 3.0 file in this guide on any other device or you will probably brick down that device.

BEFORE WE BEGIN

• Enable the USB Debugging Mode on the Amazon Kindle Fire HDX device by tapping on the Menu > Settings > Developer Options > USB Debugging Mode.
• Unlock the Developer Options if it as hidden menu on your Amazon Kindle Fire device by tapping on the Menu > Settings > About Device > Model Number 7 times.

HOW TO INSTALL TWRP RECOVERY ON AMAZON KINDLE FIRE HDX

1. Download the custom recovery (TWRP) for the 7 inch version here or the 8.9 inch version here.
2. Set up adb and fastboot on your computer using our guide for that and then come back here and continue with this guide.
3. Extract the TWRP file to the desktop and then drag it over to the same folder as adb sits.
4. From within that same folder where your TWRP and adb is, hold the Shift key and right-click where it is showing nothing but the white background of you’re folder and it should bring up a new menu.
5. Choose to open a new command window here from that same menu.
6. Type the first command from the command prompt window: adb reboot bootloader
7. Type the second command to flash your recovery: fastboot flash recovery twrp.img
   – you should find the file name of your custom recovery is twrp.img already. If not, you must change it so they match.
8. Type the last command: fastboot reboot

Any device that is wiping the custom recovery and restoring the stock recovery should boot the Amazon Kindle Fire device directly  to the recovery mode instead during the first time boot. That way the custom recovery will boot, and when it does, you will always have the TWRP booting in the future.
