Whoa, That was a battle,
My MicroUSB port got unsoldered as many of you know the problem
So, I followed this tutorial:
Cleaned every pad
I had BAD LUCK and 2 of the pads where broken, so I had to scratch some of the plastic to uncover some copper beneath.
Then, I resoldered the microUSB …
It really really was a pain, but I took a scope, a microsoldering station and lots of patience !
I am unsure if the proximity sensor or the light sensor got destroyed … they may have but at that point it was
a phone without proximity sensor and light sensor (which to me seemed a better option !)
I hope this helps !
