Sprint M7 stuck at white HTC screen

I'm stumped as I had a bad flash leave this M7 stuck at the white HTC welcome screen.

Which looks like I need to use a RUU to get back to stock. Downloaded several and with my Hboot at 1.55 thought that:

Is it just time to move on and get a new phone? :crying:
