How to Install TWRP Recovery on the HTC Butterfly (X920D)

To root the HTC Butterfly, you’ll need a custom recovery before anything else but on doing so, it’s not just root access you’ll be achieving.  Having a custom recovery (and being rooted) will give you the power to back up your device state before trying a new custom ROM just to fall back on if you don’t like what you flashed, or use the custom recovery to wipe cache/data/system so you can start afresh.  Of the custom recoveries available though, the TWRP Recovery seems to be the current popular choice as it offers touch-based menus rather than the older recoveries where you had to use the volume rocker and power/home buttons to navigate.  The guide below will show you how to install TWRP Recovery on the HTC Butterfly and later on, you can also root your device pretty easily!

I.  Before You Begin

1.  Back up everything you feel is important before you begin.

2.  Charge your device to 75% or more before you begin.

3.  Make sure that your device is bootloader unlocked.  If not, go to HTCDev and follow the instructions there.

II.  Necessary Downloads

4EXT_Recovery_Touch_v1.0.0.5_RC5_flashing_tool.zip

III.  Installing TWRP Recovery on the HTC Butterfly

1.  Enable USB Debugging on your device.  To do this, go to Settings > Developer Options and tick the USB Debugging checkbox.

2.  Connect your device to your PC.  If your Windows PC installs drivers at this point, let it do so and then continue.

3.  Extract 4EXT_Recovery_Touch_v1.0.0.5_RC5_flashing_tool.zip to a folder on your desktop.

4.  From the extracted folder, double-click on Start Here.bat to open up a black Command Prompt window.

5.  Type in adb reboot bootloader and hit the enter key [Your phone should now enter bootloader mode].

6.  Once in the bootloader mode, type in fastboot flash recovery recovery.img and hit the enter key  [this will flash TWRP Recovery to your device].

7.  After the flashing is over, type in fastboot reboot and hit the enter key to reboot your device.

And that’s it, you now have TWRP installed on your device.  To access TWRP Recovery, hold both the Power and Volume Down buttons until you see the bootloader menu, then select recovery.
