How To Perform A Hard Reset On X1
There are two ways to hard reset the X1.
First way - Start>Settings>System>Clear Storage then enter the number 1234 and press Yes.
Second way - Press and hold the two silver keys (left and right) situated just below the screen. Now insert the stylus pen into the tiny hole which is situated around the bottom right of the back of the device for 5 seconds. Follow the on screen instructions.
It is advisable to back up your data before performing a hard reset.
FYI - a soft reset can be performed by ONLY inserting the stylus pen into the tiny hole for 5 seconds.
