Help! rom flash failed

[Guest festering]

Hi all,

Tried to flash a rom and it failed i now have a screen made up of alternating white lines.

I have tried to flash again but the utility does not find the device

I have tried to hard reset the phone and am left with a balck and white screen with the words clean boot.

Does anyone know how to fix this or have a rom I can flash from the sd card?
