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


Note: 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: http://teamw.in/project/twrp2/225 (See hint below)
  2. Download "UPDATE-SuperSU-v2.14.zip" from here: http://download.chainfire.eu/supersu
  3. Copy "UPDATE-SuperSU-v2.14.zip" to you phone's internal SD
  4. Open a command prompt and navigate to your fastboot executable.
  5. 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.
  6. Connect you phone to the PC
  7. Type "./fastboot boot path/to/where/you/saved/m8-dual-twrp.img"
  8. --> 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
  9. Touch "Install"
  10. Select the "UPDATE-SuperSU-v2.14.zip" file
  11. Swipe to start
  12. Touch Reboot System.
  13. You're phone should be rooted.

** Hint **
If the official TWRP does not work for you, you can try this one here: http://forum.xda-developers.com/htc-...1/post54258731
****

This method should allow you to receive and install OTAs. But I won't vouch for that as I have not received an OTA yet.

Cheers,
Chris

PS: @donmarkoni provided some resources that might be useful to you. See his post: http://forum.xda-developers.com/show...5&postcount=12

Changelog:
[2014-10-20] a) I have been hinted that the official TWRP should work for the m8_dugl as well. b) The current version of SuperSU is v2.14 and works well. c) @donmarkoni provided some more resources worth mentioning.

Just wanted to mention that you cannot install any OTA having a custom recovery on. So, if you have stock recovery and want to just get root, you can use this command instead
Code:
fastboot boot recovery.img
. This should get you in recovery without flashing it, so just do your thing, restart the phone and you're set.
Also, note that by unlocking your bootloader, you loose pre-loaded programs that need to be installed before performing an OTA update; that includes calculator, and so on. So, you need to install the pre-loaded apps before performing the update + you need relock the bootloader!

Cheers!

@claudenegm: to be honrst, i really have no need of ota now as this 4.4.4 Maximus rom is great. Lolipop is not scheduled until well into next year so will only consider going back to stock to ota if there is no Maximus type rom available.
And only if there is a need for update anyway.
But thats just me

in your instructions you wrote it only works for 'm8_DUGL'. I got a my HTC one M8 dual sim from China Telekom and in the bootloader it reads
M8_DWGL PVT SHIP S-ON.
HBOOT-3.18.0.0000
Radio-1.09.30.0903
OpenDSP-v38.2.2-00542-M8974.0311
OS-1.32.1401.12
eMCC-boot 2048MB

wondering if your instructions work for 'DWGL' as well?

Stock Recovery 3.33.401.6
Guys,

Since Lollipop should be out anytime soon for our devices (m8 single sim already has it), I'd like to revert my TWRP recovery to Stock in order to have OTA updates.

Does anyone have the stock recovery image so I can flash it back? Can I still install the update through HTC Sync Manager even though I'm with TWRP?

Thanks for the help!
