Issues with a Hansshow rear display 7.2 inches H72

[Cornell N]

I installed a new Hansshow Android Entertainment H72 rear display for Tesla 3. I don’t know how but the screen is frozen and I get the “Child Lock Has Been Opened “ message. Trying to deactivate the child lock I am required to type a passcode, which I don’t have and couldn’t find anywhere else.
Any suggestions or help is appreciated.
Regards

This is the Model X forum. Additionally, tbh, that’s a crappy (non Tesla) mod that has no tie-in to Tesla’s software, so of course it’s going to have issues, and there isn’t much we can do.
