How to repair charging port

Hi Afrian,

I'm going on the assumption that you have definitely identified the charging port as the source of the problem, and have verified that your charger and charging cord are both working correctly.

If that's the case, then you're in luck; it's actually a fairly easy repair as far as cell phone repairs go. The charging port is located on an auxiliary, or daughter, circuit board at the bottom of the phone. So you don't have to worry about a difficult soldering job to replace the port; you just put in a new board and you're all done.

Sorry to say that iFixit doesn't have a guide to that repair, but the Nadie Me Llama Gallina site in Spain has just what you need. It is, of course, written in Spanish, but used with the Chrome browser's translation feature, it really won't matter what your native language is.

The part itself appears to be easy to get; I suggest starting with sites like Amazon, eBay and AliExpress, but there are undoubtedly many others as well. Here's one of the first ones that came up on my cursory search.
