Xteam will not reply to emails regarding poorly installed chip that refuses to boot. They had two tries at installing properly. They said they replaced the "faulty" chip, but this has been confirmed as a lie. I have had to pay local installer and will now have to buy replacement chip due to their lack of honesty and poor workmanship. They will keep your system for weeks and continually tell you they are shipping soon...good luck if you use this company.
