Hello

I rooted my phone and when i flashed the SuperSU.zip, the phone rebooted but it stayed on the htc powered by android screen. I can access the bootloader and i am running CWM v6.0.4.8. Also when i run adb devices it does not show any devices. I really need help with this because i don't know what to do.

Use TWRP. I started with the openrecovery-twrp-2.7.0.2-m8.img version. It works with chainfire SuperSu. I think you can also use openrecovery-twrp-2.8.1.0-m8_whl.img but not sure. For higher version I'd to use SunShine.

It's because of your recovery dude. CWM is not maintained anymore and won't work with newer stuff. I recommend TWRP version 2.8.7.0 or newer.
After you flash the TWRP recovery onto your phone via fastboot, download a ROM and place it onto your extSD. Boot to your new recovery and flash the ROM. Most M8 ROMs come pre-rooted, so there is no need to flash SuperSU

If the phone is on MM, you will also need a current version SuperSU (v2.76 recommended) in order to root.

Outdated recovery and/or outdated SuperSU = no boot

"whl" indicates that recovery is specifically for Sprint version M8. Should not flash this on any other M8 versions.

For higher version I'd to use SunShine.

Spending money on sunshine is not required to root, on any OS version on this phone.

All you need is an unlocked bootloader, right TWRP version, right SuperSU version.
