[Q] Rooted and now having trouble flashing VZW roms?? topic

I bought a rooted gs3 on EBAY...

It is running liquidsmooth rom.. I have tried flashing some other VZW roms (esp. want to try out kit-kat roms) and I get an error during the flashing process..

See attached image...

Did I get taken on Ebay??? Not sure what I am doing wrong...

Thanks in advance for any help
