screen doesnt turn on. would it hurt battery if I tried charging it with another phone's charger? dunno about the voltages, i havent found the other charger yet, but if it's about the same, can i charge it for about 5 mins? (the end of that charger is ripped off, so I can attach wires directly to battery)
To my knowledge, running the battery dry is not capable of destroying the phone - and it really shouldn't be in any decently made device, in general. Have you tried physically pulling the battery, and then replacing and charging again?
