Hello everybody,

Is it possible to downgrade CRD3.10 after update by dealer if i make backup with Kess over OBD before the update?
Is there some special procedure or writing the old backup over obd will be fine?

Thanks in advance.

You can't do downgrade by OBD with KESS. You need only FULL by KTAG, etc.
