hi guys, I have searched and searched, and can't find an issue like the one I'm experiencing. I made the mistake of letting my battery run all the way out. When I put it on the charger the battery just flashes with no lightning bolt, and it tells me it's locked. I hold the two arrow buttons down and it unlocks but still flashes empty battery. Then it goes right back to locked! It did this once before and I ran it up to the vape shop. Dude was able to fix it immediately by, of all thing, holding the two arrow buttons down and unlocking it. The exact thing I was doing. I don't know what I'm doing wrong here. Has anyone else run into this??
