The phone is a T-Mobile HTC One (PN0713000 T-MOB010)
I had previously unlocked the bootloader via HTCDev, flashed ClockworkMod, SuperSU, etc etc, and was starting to try out different ROMs. After having Cyanogenmod for a couple days I started performing all the backups via CWM and Titanium, saving the files over to my computer, so that I could try out something else. While attempting to install a stock ROM it failed and left me with nothing but a Cyanogenmod bootloop and the ability to fastboot and get into ClockworkMod Recovery. However, when booting into CWM Recovery it says this and seems to not contain ANY partitions or folders:
ClockworkMod Recovery v18.104.22.168
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
Attempting to flash a stock RUU and just get the phone to at least boot and let me start over gave me this:
[HIGH]C:\HTC One>fastboot flash zip 1.29.1540.3miniruu_tmoible_.zip
sending 'zip' (951927 KB)... OKAY [ 95.406s]
writing 'zip'... INFOzip header checking...
INFOzip info parsing...
FAILED (remote: 99 unknown fail)
finished. total time: 95.672s[/HIGH]
I've tried flashing ROM zips that way as well and keep getting similar errors. I'm not sure when to use adb (hboot, fastboot, recovery, or only a booted OS), but I can't get a response from "adb devices" so I haven't had any luck doing an adb push or adb sideload (from within CWM).
Please tell me I have some options here...
