I purchased a used Nokia N9 in April and I was aware of it having a few scuffs and what not. The usb cable had to be positioned in a certain way in order for the phone to charge. Well, now the port has become very loose and there is no way for it to be charged

My N9 has about 3% battery life. I really don't know what to do. Worst thing is, two of the torx screws are stripped and so I cannot fully disassemble the phone.

Can someone help me please.
