How long do I need to press & hold the Volume up key, power button and menu buttons. When I press the Volume up key and the menu buttons at the same time, It says on the upper left on the screen Recovery Booting is it a good sign? How long it will take to finished the recovery? Also, do I have to leave it plug? Also, do I need to remove the Sim card & SD card?
Hold them till you see the recovery booting on the screen, you can release them then. You do not need to remove the Sim or SD card.
