I’ve had mine for about 5 months and today it just died while I was out.
I’ve tried holding the power button but to no avail.
So I waited til I got home. Plugged it to my laptop’s USB port but it wouldn’t charge.
Well good thing I bumped into this forum, read and followed some button combination and none worked.
So here’s what I did to make mine come alive!
HOME + HOME + POWER (do not hold. just press the combination buttons within 2 seconds)
I’m so happy that it worked!
