Default Soft brick or bricked?

Hi,
I currently have the HTC with TWRP. I had the android revolution ROM by mike and i was trying to install the Elemental X kernal. I must have done somethign wrong because now TWRP is now saying

Unable to mount/system and unable to mount /cache

So i thought I would just adb sideload a rom and reflash. Unfortunately my device is not being recognized either

.
So I can get into bootloader and I can get into TWRP. Also I can still get into my Internal Storage

Is there any chance of recovering my device??

additionally the fastboot commands still work

in advanced settings there is soemthing caleld HTC dumlock in TWRP? can this help in anyway

additionally fastboot commands like getvar still work

Unforunatley I did not make nandroid backup or anything either.
