iPhone 6 shows "not certified cable" and isn't charging

I am currently repairing a phone which I though had a lightning connector damage, as it showed "this cable or accessory is not certified and may not work reliably with this iphone" with all chargers and cables (i tried 3 different cables which work perfectly with other iphones). I tried plugging in another battery as the original one was completely empty, I can boot the phone but it still brings up this message everytime I connect the charger. I replaced the lightning flex as well but it still shows the same error message. Already tried cleaning the port but still nothing.

I think I've tried everything but I can't get the phone to charge.

Does someone have an idea?

Can you still use the iPhone or is it a hard stop? If the customer will let you I'd backup the phone and try wiping it and doing a clean iOS install.


With another battery I can still use it but the battery only had a few percent left so I wasn't able to do a backup. I could only wipe it via settings because I can't connect it to iTunes...

Try cleaning the charge port and reinstalling cable, charge port could be defective and in need of replacement.
