Help stuck in bootloading screen

[accurato]

i must be daft, or getting there. I need some help please. when i boot up what i see on the tri colour screan is

RAPH800
SLP-0.37.0000
MicroP-Hermann(LED) V0c85
MicroP-Hermann(Key) v0685
PSOC-Raph STAGE-EVT v20

Upgrade ROM code error
please try again

I must have done something wrong like reading when it's late and flashing a wrong ROM.
when i try to flash RUU and it gets to image version on the top it's blank and hangs on the leading screen. I have tried to boot from an sd card and it hangs in the loading screen, if i try a larger file i get and error

00028002 on the loading screen with not allowed

How can i re flash the whole system if it's possible i think i flashed 6.5 gsm by error. Is my phone a paper weight now.
