It's seems that i got locked outside my m2Note.
Someone hacked my gmail account and turn on screen lock and chaged my previous lock passcode.
I can now only enter in guest mode using 1234 passcode.
Can not do factory reset or anything else.
Does anyone have idea how to use my phone again?!

Thx in advance
