HTC One M8 (VZW) Stuck in Bootloop/Fastboot

[Ben Chardell]

Hi Guys

Long story short, I'm an *****. I tried to install Android Revolution HD using the wrong firmware. I'm now stuck in two places: either endless HTC logo or bootloader.

In fastboot, the only thing it lets me do is reinstall what I think is the last version of the firmware, as it's still on my SD card. I can post a video using an old camera shortly.

Does anyone know how to fix this? If I could get to recovery, I could wipe data and load a backup or an old rom...

Thanks!

Edit: I think i figured it out. Bootloader was auto-detecting the old firmware zip as i thought. Took the memory card out and it let me go right to recovery. Remounted the memory card and I'm now installing Viper Rom (what i was running before). Crossing my fingers that it works!

Let this be a lesson to all of you... always read the full xda threads...

I've had my share of such problems on my M7 and it taught me not to do it on the M8. I really hope it works for you man, and Viper is definitely a beautiful ROM. Let us know how it goes for you, and if not I can try to find you a RUU to fix all of this, or at least a stock Nandroid.
