Chosen Solution
My iPhone 5c kept saying “This accessory may not be supported”. I knew what the problem was, I had to get a different charger. I kept putting it off and off. This morning it kept doing it and doing it , more than usual. When i was closing my apps it said it twice in about 0.2 seconds. I tried to press dismiss but it wouldn’t work. I shut my phone off and tried to do it, and it wouldn’t work. Now it’s been about 20 minutes of me trying to press dismiss. I can’t do anything with my screen or anything like that. Someone tried to all me but i couldn’t slide it to answer it. I tried restarting it but, as we know, it is not letting me work the screen. it still says “This accessory may not be supported” how do I fix it??
@albertypoopy hold down the sleep/wake button and the Home button at the same time. See if it turns off. You now may have a failed lightning port but try to restart without anything connected to the phone. Also use some puffs of compressed air to try to clean the port.
I agree with the previous answer. You can also try some of these solutions if that doesn’t work. http://vkrepair.com/iphone-6-parts-diagr…
