Users are still feeling bad about Motorola’s not unlocking the bootloader for the Droid RAZR HD. Though it’s possible to root the phone without unlocking the bootloader, a locked bootloader still limits further development.

On the other hand, some lucky individuals were able to acquire the Motorola Droid RAZR HD XT926 Developer Edition, which has an unlockable bootloader, allowing for customizations to be developed. Though these customizations might smell and look really good right out of the developers’ kitchens, you won’t be able to do anything if you don’t have custom recovery. Thankfully, XDA Developers member GoClifGo05 has given us some helpful tips on flashing TWRP Recovery to the Droid RAZR HD.
TWRP Recovery is a custom recovery that allows you to easily install custom ROMs, kernels, themes, and other modifications. This recovery also allows you to easily create NANDroid backups (which can be really useful in case you run into some problems during flashing), wipe data for a clean slate, and of course, flash modification files.
This guide shows you how to flash TWRP Recovery for the Droid RAZR HD XT926 Developer Edition.
