Unlock/Change IMEI on W810 SEMCTool v8.4?

[sia_26]

way would you change IMEI?? and it is even illegal in most countries..

I'm aware of that. I bought the phone on eBAY, and the seller didn't mention anything that it was barred:/, and the he doesn't answer my emails either, so should I just drop it in the trashes? Hell no.
