I'm trying to do a factory reset on my HTC one mini 2 following the instructions on HTCs website here: http://www.htc.com/uk/support/htc-one-mini-2/howto/511217.html
I can't access settings (it dumps me out to the home screen, hence the need for a reset), so I'm trying the hardware buttons method.
I hold volume-down, then hold the power button as per the instructions. After about 7 seconds, a black message box pops up saying "to restart your phone, press and hold the volume-up and power buttons". If I keep holding volume-down and power the screen then goes dark. Nothing else happens. If when the message appears I let go, the message disapears, and my phone just returns to the locked screen, I can unlock it as usual.
I'm completely flummoxed, any ideas what to do next?
