Check accessory compatibility

Not all accessories are compatible with certain iPhone or iPad models. Make sure the accessory you connected is compatible with your device. You will see the "This accessory may not be supported" error if it's not.

Usually, the accessory packaging has a compatibility indication. You can also check compatibility with the seller or the manufacturer's official website.

Check the accessory connection

Make sure the accessory is connected properly. Check if you have fully plugged the cable into your iPhone or iPad port. The connection won't be detected fully if it's loose, and you'll see the error message.

Unplug the accessory cable from your device and plug it back in again. If both devices are compatible and there are no other issues, the error message shouldn't appear. If you're still seeing it, proceed to the following method.

Clean the connection port

Another reason you can't connect your accessory and keep seeing the error message can be a dirty port or cable. Over time dust and other debris accumulate in the lightning port. Take a small non-conductive tool and carefully clean the port. Clean the accessory lightning connector with a cloth as well.

If you're scared you'll damage the port or the connector, take it to an authorized service for a professional clean.

Check for port and accessory damage

If cleaning the port and the connector didn't help, check for mechanical damage. If you see apparent mechanical damage in the device port, take it to an authorized service to get it checked out and fixed.

If the port is okay, check the accessory lightning cable. If it's visibly damaged, replace the cable. Otherwise, you won't be able to connect it to your iPhone or iPad.

Perform a Device Firmware Update

The Device Firmware Update (DFU) will erase everything on your device and eliminate all errors that could've corrupted the operating system. This mode is similar to the Recovery Mode on Mac.

Before running DFU, make sure to back up all your important data, as everything will be lost.

To perform DFU, follow the steps below:

1. Connect your device to a PC or a Mac.
2. Press the Volume Up button and release it. Then quickly press and release the Volume Down button
3. Now, press and hold the side button for about 10 seconds until you're screen goes black. Don't release it!
4. Keep holding the side button and simultaneously press the Volume Down button for about 5 seconds.
5. After 5 seconds, release the side button, but keep holding the Volume Down button for 10 more seconds.
6. When you see a "Your computer has detected an iPhone in recovery mode. You must restore this iPhone before it can be used" message in Finder or iTunes, release the Volume Down button.
7. Click on "OK" and select "Restore iPhone".

If you see an Apple logo or your iPhone restarts in the process, something went wrong. Carefully follow all the steps again.
