Check whether your accessory is an MFi-certified one

“This accessory may not be supported” can appear if you don’t use an MFi-certified lightning cable. In fact, this can be one of the most common reasons behind this issue. This issue can appear just after plugging the device into a power source using a lighting cable. If the lightning cable doesn’t come with MFi-certification, it will not work correctly with Apple devices.

If you have purchased a lighting cable from a random place, you are likely to have issues with it. That is because those cheap lighting cables don’t have the standards Apple expects. More importantly, cheap lighting cables that aren’t MFi-Certified can even cause damage to your iOS devices (through excessive heat). So, you should make sure that you use the original lighting cable to eliminate potential mishaps. If the original cable is damaged, you can go to an authorized Apple dealer and get a new one. If your device is under the protection of the AppleCare plan, you can get the cable exchanged.

Should you have other errors on your iOS devices, such as iPhone frozenFacebook messenger not working or iPad frozen, just switch to them.

Perform a restart to solve “the accessory may not be supported” issue

If there is nothing wrong with the lighting cable, the next basic solution you should try is a restart. A restart can easily fix a variety of minor software glitches associated with iOS systems.

The way you perform a restart might vary depending on the iPhone model you are using. ‘

If you use an iPhone 8 or an older version:

  • Press and hold the power button
  • Swipe the power slider towards the right-hand side
  • Once the iPhone is switched off, you can turn it on by pressing the power button

For iPhone X/XS/XR/11:

  • Press and hold the side button and any of the volume button
  • Once the slide button appears, swipe it
  • Press the power button once again to switch on the device

Be sure that you wait for about 30 seconds before pressing the power button back to switch on. After restarting the device, you should connect the accessory once again to check if it works. If you don’t see “this accessory may not be supported” message anymore, the problem is solved.

Check if the accessory is working fine

If none of the above is the case, you should check if the accessory is working fine. This means, if you have connected a device to the iPhone with a lightning connector, check if it works. Check closely if the lighting cable is connected properly and the port is not loose.

Does the port of the device have some discoloration? Does it have a worn off port? Is it too loose? Does it have dust or stains? If your answer is yes to one of those questions, you may have to change the accessory. You can try a different accessory and check if the same error message pops up.

If the accessory fell into water recently, it can malfunction even though the outer appearance is fine. So, you should recall your memory and make sure the condition of the device is perfect. Check the USB end of the cable as well.

Look inside the lighting port

If you are 100% sure that there is nothing wrong with the accessory, you should check inside the lighting port. If you notice any dirt, debris, stains, fungus, etc. in the port, that might cause some issues. The external substances can prevent your device from making a solid connection with the cable.

To make it sure, you should find a powerful flashlight and have a close look inside the lighting port. If you can find something strange inside the lighting port, you must clean it with a suitable brush. It is better to use an anti-static brush.

Check the charger of the phone

If you notice that “this accessory may not be supported” message is still popping up, check the charger. If the charger has something wrong with it, you will experience the above issue. Make sure that you look inside the USB port of the charger and find if there is anything wrong. To clean it, you should use a brush and get it cleaned. The potential debris and dirt inside the USB port will prevent the device from making a good connection. Also, you can use different chargers to see if the problem is persisting. However, if you notice the message even after changing the charger, the problem is not with the charger.

Update the iOS device and check if the problem resolves

Some of the accessories that are manufactured for iOS devices require the newest operating system to function properly. If you don’t see any physical defect with the devices or the accessory, it is worth checking the iOS. If you have an older version of the iOS, it is always better to update it. Such an approach will also help you to make your device securer as well. To check and update the software, you must do the following.

  • Go to “Settings” app and tap on “General” option
  • Go to “Software Update”
  • Then, if there is an update, you must download it by tapping “Download”

However, before you update the iOS, you must ensure that the device has enough battery life. That is to say; it should have at least 50% of the battery. During the installation process, the iOS device will turn off. Also, there will be a status bar appearing on display. You can notice that the update is completed when the status bar is full. The iOS device will then turn on at the completion of the OS update.

DFU restore the device

In certain cases, the reason behind “this accessory may not be supported” error would be a serious software issue. To fix such an issue, you should perform a DFU restore. Through a DFU restore, you will be able to overcome a variety of potential issues associated with iOS devices.

Before performing a DFU restore, you must know that all the data will be deleted. However, the DFU restoration will load all the data back on the iOS device.

In most of the cases, the options we have mentioned above can fix the issue.

But, if your device still gives the problem, the issue must be something else.

Repair the device

If your iOS device still shows the same issue even after following the above steps, you may try repairing. That means you will either have to repair the iPhone via third-party professional iOS repair tool, like Tenorshare Reiboot & iMyfone Fixppo, or get a new accessory.

Be sure that you keep backups of your important data saved on your iPhone on a regular basis. Such an approach would help you to prevent potential data losses. If you have backed up the data recently, you don’t need to worry about factory resetting a device.
