Root Deleted OS, can't get into recovery - HTC One M8

[Neus]

As the title said, I have deleted the OS. When I boot my phone, the screen briefly shows the TWRP menu, but quickly goes away, as I cannot interact with it. Sometimes it flashes a few more times, but that's it. If I try to boot the phone, it remains stuck at the HTC boot logo. Please help!


One more thing, my volume down button isn't working.

You're in quite a spot.

Did the volume down just stop working as part of this or was it broken before you started this?

It was broken before.

Adb, fastboot, and an RUU are all out of question.

You're going to have to get it serviced.

Well I guess that's it. Thanks for your time and help !

You're welcome - wish I'd had better news.

You said that it almost boots into TWRP - if that's the case, it's possible you have adb long enough to boot to bootloader and apply some sort of firmware or RUU. Have you checked whether you have adb access when trying to boot to recovery? You really only need it for a second to get it to boot to bootloader.

I've searched shipped ROMs for a Ruu, but there are 2 links (m8vzw_sense6_4.4.2.zip and RUU-HTC_One_M8_GE-1.16.1700.16.zip) which one should I choose?

That only matters if you can get into the bootloader. Were you able to do so?

Sadly I wasn't able, due to the volume down button not working.
I'll send it into service to get the button fixed.
Thanks anyway!

Get adb here and the universal adb driver in the post after that -

Unzip the sdk-tools.zip file, it creates the sdk-tools folder. Install usb driver.

Shift+right_click the sdk-tools folder, choose Open command window here.

Plug phone into pc. In the command window say -

adb wait-for-device reboot bootloader

And cycle power on the phone, volume up plus power will do.

If that doesn't work when you see TWRP go by, try this as soon as you see TWRP -

adb reboot bootloader

Captain, please say if I'm wrong.

Will try tomorrow, it's kind of late here and I'm going to bed.
