Problem with micro usb port.

view story

http://forum.xda-developers.com – Hi xda. I cant charge my phone. I made tests with 3 original micro usb cable, and got nothing(wall and usb). I got no led, no sounds when i plug it. So, I tried with a universal charger for batteries, and it works. So i guess my battery is fine. Apparently my problem is the micro usb port. I do not have warranty. Despite having no experience with maintenance, I found a video on youtube and did not seem very difficult to replace. So i searched and found on ebay a new micro usb port, for a very low price. What you guys suggest? Lead to assistance and wait 15 days or more, and spend m (HowTos)
