How to root the HTC One M8 Dual SIM.

Disclaimer
As always, if you **** your phone up, it's not my fault. Don't blame me. Further, I will not answer any questions about this. Please help yourself.
Prerequisites

• HTC One M8 Dual SIM (m8_dugl)
• A complete backup of your phone! (e.g. with titanium backup)
• fastboot installed
• USB Cable
• Some time (do not hurry!)
• htc DEV UNLOCK (http://www.htcdev.com/bootloader/unlock-instructions)

Warning
Make sure you have a "m8_dugl" device:
Reboot your device to the bootloader (POWER+VOLUME_UP until the screen blacks out, then POWER+VOLUME_DOWN). If it reads there something different than "m8_dugl", then this guide is not for you!
Steps

1. Download the custom recovery "TWRP" from here: https://s.basketbuild.com/devs/Capta...)/ALL/Recovery (See hint below)
2. Download "UPDATE-SuperSU-vX.XX.zip" from here: http://download.chainfire.eu/supersu
3. Copy "UPDATE-SuperSU-vX.XX.zip" to you phone's internal SD
4. --> Until now no harm has been done to you device but DEV UNLOCK. So this would also be a good time to do a BACKUP! #JustSaying
5. Open a command prompt and navigate to your fastboot executable.
6. Put your phone into fastboot mode: POWER+VOLUME_UP until the screen blacks out, then press POWER+VOLUME_DOWN. You see some options soon. Use the volume buttons to navigate, the power button to perform the selected action. Select FASTBOOT and press the POWER button

1. Connect you phone to the PC

1. Type "./fastboot boot path/to/where/you/saved/TWRP_Recovery_x.x.x.x_M8_CPTB.img"
   If boot does not work, you can flash the recovery to your phone. But remember: When you do a stock update, you must revert back to a stock recovery!
   Do flash the custom recovert, type "./fastboot flash recovery path/to/where/you/saved/TWRP_Recovery_x.x.x.x_M8_CPTB.img"
2. Touch "Install"
3. Select the "UPDATE-SuperSU-vX.XX.zip" file
4. Swipe to start
5. Touch Reboot System.
6. You're phone should be rooted.

If the newest TWRP does not work, try a different one.

If none of them work, try the official one:

If the official TWRP does not work for you, you can try the following one, but it's rather old: http://forum.xda-developers.com/htc-...1/post54258731
