[One (M7) Q&A, Help & Troubleshooting] TexMachina:
I am looking for some help in getting my HTC One M7 back up and working.

I used the online Cyanogenmod installer on my at&t HTC One M7 and it worked for the most part including where it contacts the HTC site to place the phone in developer mode.

Unfortunately the radio was far weaker and was losing it's signal all the time. I tried a few nightly's in hopes it was a bug that would be addressed but the issue with radio strength continued. Then an alert about an update from Cyanogen popped up and I trustingly clocked OK thinking that perhaps THIS would fix the radio stregth issue and I can keep my rooted ROM. Instead it broke Bluetooth entirely.

So I watched a YouTube video on restoring to stock. Apparently I can't post the link,

I got all the way to the part where I use fastboot to install the zip, HTCOne-32GB-ATT-5.12.502.2-TWRP-stock-unrooted.zip

It failed but not in the manner described in the video I believe it is due to the phone security set to S-ON but I have yet to find a way to set it back to S-OFF from where things are now.

This was the steps from the video I followed starting with fastboot getvar version-main and the fastboot oem lock

I then went through the following commands

C:\fastboot>fastboot erase cache

erasing 'cache'...

OKAY [ 0.054s]

finished. total time: 0.054s

C:\fastboot>fastboot oem rebootRUU

(bootloader) Start Verify: 3

C:\fastboot>fastboot flash zip HTCOne-32GB-ATT-5.12.502.2-TWRP-stock-unrooted.zip

sending 'zip' (1249780 KB)...

OKAY [ 47.434s]

writing 'zip'...

(bootloader) signature checking...

FAILED (remote: 12 signature verify fail)

finished. total time: 171.191s

And so it failed. The HTC screen came up but there was no progress bar so I know that fast boot is talking to the phone. I have been looking for a fix ever since and I am presently using a flip phone while working on getting the HTC One back.

Presently the phone boots directly into fastboot and will not allow me to do anything but reboot or power down but I can still use fastboot.

Revolutionary just sits at waiting for device.

The HTC One Toolkit is of no use as it also cannot see the device.

This is what is on the screen presently. Any help would be appreciated.
