Default [HELP] BOOT LOOP! No recovery! Only fastboot! Please help!

I updated my HTC One which had an unlocked bootloader.

It boot looped on restart so I decided to lock bootloader and flash RUU. The RUU flashed ok so I was happy to see it all done, but bootloop again on restart.
So I thought fine I'll just unlock bootloader, flash recovery and run custom software. Problem is recovery seems to flash fine but it bootloops when booting recovery. I have access only to fastboot so I have ran out of knowledge on what else to do will be grateful for some help. Thanks

As you can see from below my meid is showing as 00000000000000 i haven't edited it and cant understand. I have the feeling my system partition might be damaged. I have done search for system.img files but cannot find any for rom version.

a simple fastboot erase cache from fastboot in the bootloader should fix the boot looping. Then when in recovery maybe wipe every partition and flash another Rom?
