I am getting too many pattern attempts error on my Sony tablet S model SGPT122A1/S
Therefore I want to hard reset this device. I have tried following method but it doesn't work. Any idea how to factory reset it?
1. Turn off tablet
2. Turn on tablet by pressing Power and Volume up button at the same time.
3. When you see Sony logo, release Power button but keep pressing Volume up button
4. After some time you will see menu where you will find option to do reset
When I do above procedure the tablet just boots up normally and no menu is shown where I can do hard reset.
