So this iphone 5c looks and seems to be functioning well but it’s stuck in the activation screen. It says 3g and some black dots so looks like signal top left. But there is no Wi-Fi icon. So I assume that possibly the Wi-Fi antenna is broken? But surely the mobile signal should activate it anyway? So more is wrong? Thanks Update (01/22/2017)
well here is a photo inside and immediately I see some kind of white stuff on the charging port almost like yogurt. I think maybe I can change that if it’s worth it?
There is some sand but there’s not really corrosion I think but I’ve not studied it in detail yet.
Try it on different cords. I would suggest an apple oem cord. You can also try different ports on your pc, or a different pc
Normally if you have a SIM card in and are able to connect to a 3G network, you should be able to activate. If your iPhone says “activation currently unavailable” or something like that, try connecting it to a computer and activating it through iTunes. It might fail too, but at least iTunes will give you a more detailled error on why the activation has failed. If we have an error message we can try isolate the source of the problem :)
