Hello, i have an Utech UM-760 tab, i put an unlock pattern on it forgot it and i've been unable to remove it

i've tried to perform a data wipe, but i'm not able to get into recovery mode (or do not know the right combination of keys)

So far:

PWR + Volume Down: Boot in Safe Mode
PWR + Volume up: Nothing
Reset Button: Just Reset

Hold Volume Down, then also hold Volume Up: Test Mode, i get the following screen:



The RockChip software tools do not detect it to restore it, im guessing it needs either recovery mode or usb debugging mode ON

I appreciate your help on this, i can't even find a Utech website for support! Thanks
