Used wrong charger for LG Volt, will not turn on.

My father has an LG Volt LS740 and today he used a Blackberry charger which I'm about 67% sure is a different voltage. It charged his phone up to 6% from its 1%. Then, after he unplugged this charger and plugged in his own, his phone shut off and has been off since. We tried hard resetting and soft resetting and even the old "home button and lock button" trick that works on iPhones, but nothing has worked. Is there anything we can do to get it back on? Thank you.

Answer this question I have this problem too

Is this a good question?

Ok so one possibility is that the blackberry voltage was to high and caused the charging circuit to fail.In which case components on board will need replacing. The only trouble shooting i can think for you to do right now is to take the battery out for say 10 min and then re insert and try to charge. Also try another charger that is compatible with the phone and let it sit for awhile and see if it gets warm. the back of the phone that is .

I did the same thing with the same phone. He most likely fried his battery so it won't ever charge again. He can turn it on by cutting the charger cable end and find which wire is positive/negative the strip a tiny bit from both ends. While the battery is still installed youll look for this; + - should be at top left corner. Slightly lift the battery out so you can fit your pos and neg wires between the battery and the fixed prongs on phone. Once they line up, place battery back in place. For proper contact the wires should not be able to pull out easily. Now plu in the wall unit and turn your phone on. Enjoy your new land line :)
