Hi there and welcome
The only way to remove the pin is to reset the device. This will remove all your data and return the unit to new, but it is the whole reason for the security.
In order to do the reset, please perform the below steps.
The unit will then be returned to new and you can set it up and use it as a new device.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
