Hello, my tablet will not open, wrong PIN code. But I have never changed the code and have it stored in a note on my phone. It is not wrong. It is the only code ever used on the device.
What can I do?
The tablet is CHUWI HIPAD 11 / serial ZHip11EY00240402406 / purchased from CHUWI official eBay store / purchase date 14/11/24 / delivery date 27/11/24
