Ok so my blackberry's charging port and i got it fixed but now its completely dead and it wont charge at all. The red light turns on for 10 seconds then turns off again. I don't know what to do??

Buy a new device, and then correct your profile to reflect your correct model number.

Sounds like your charging port didnt get fixed after all. If you dont have much money in the repair, you could try again.
Otherwise, it may be time to look for a good used one on Ebay.
