A little part of users feedback Xtool X-100 Pro key pro get error message reading “dealer code does not exist 860010A1” when they try to register.
How to solve?
Actually, Xtool X-100 Pro does not need register; you just directly download the “update tool” from official site (www.xtooltech.com) and to update.
After download, open it and use device serial number and register password to log in and update, do not use your original register user name and password.
