HTC one m9 wont boot into OS, and cannot boot into recovery (please help)

A while ago i rooted my android Phone as per this guide: "http://ift.tt/1TBFuOo;.
Now when trying to revert to stock as per this guide: "http://ift.tt/1OdJXee; i got locked out of my Phone.
As soon as i locked the bootloader as per the instructions the Phone wont boot into Android OS and i cannot transfer the RUU file to the SDcard as i get the error: "error: device not found".

when trying to unlock the device via the command: fastboot flash unlocktoken Unlock_code.bin

i get:
sending 'unlocktoken' (0 KB)...
OKAY [ 1.008s]
writing 'unlocktoken'...
(bootloader) flash unlocktoken
(bootloader) [KillSwitch] : /dev/block/bootdevice/by-name/frp
(bootloader) [KillSwitch] Last Byte is 0X00, disable unlock
(bootloader) [KillSwitch] oem unlock Turn Off!

OKAY [ 0.019s]
finished. total time: 1.027s.

the only things i can boot in atm are the download mode and the bootloader mode.

Please advice as how to proceed.
