Hi , i have a problem with a Allwinner a33 xtreme tab x102 tablet that has a pattern lock on the screen. It has no volume buttons and i can't enter recovery to reset it. I want to know of any way to enter recovery menu. Also i have booted it from SD card with another rom to access the internal memory but i can only see the card memory even rooted. Some help would be apreciated, thanks in advance.
