 Help neded with Wyse V90 LE

Hello

I am trying to reinstall Wyse V90LE back to just a simple copy of Windows XPe

i have then on a network with a Windows 2003 server

When i try to flash them i just get an error Failed Firmware

so i am trying to find out if the files that can be down loaded from wyse is the full OS or is just the Service Packs

Has anyone got a flash file i can use to just wipe the 512k flash and give me a boot to Windows XPe please

many thanks
