Hi, the s/n and register password can be found on the about page of your device, if not send your s/n to support@autel.com to check the register password, also your al519 need not to be registered. So there is no need for searching the password.
How do I update my new AL519? I can not find anyplace to download the bin or dtc file. And the NEW out of the box AL519 will not work without an update.
