I finally found a testmode.key that worked on this unit.
testmode-x50v2-20170601T202015Z-001.zip
Here I could go in and readout the password.
Did a factory reset and the went into setting and pushed the 3 zones in the top of the screen and removed password by entering it one more time.
Now the unit works perfectly, just has to find some updated maps and my MHL interface for my phone.
