I'm using windows xp SP3 with all the drivers installed and I have downloaded the lumia 800's firmware through nokia datapackage manager.

I have followed a guide to debrand or flash a dead lumia by renaming the files and creating the folders 817. When i create the folder rm-817 the NCS product tool didn't detect it for me so i went with the rm-819. I've ranamed the files to my product name and everything went through find apart from the error before it started flashing under recovery mode. Signature verification error.

Has anyone encountered this before with the lumia 800?? If so please guide me to a work around, any help at all will be much appreciated.

This is because of the locke bootloader. You cannot flash custom ROMs. The bootloader will check the signature of the ROM, and won't flash it if it's a custom ROM.
