Apple iPhone XS Max keeps rebooting after iOS 12.1.4 update

Sudden un-triggered reboots on an iPhone apparently denote a problem that needs immediate fixing. Such symptoms usually depict system instability as you aren’t certain if you could get a task done without any interruption. Generally, automatic restarts in electronic devices, particularly computers and mobile devices are often attributed to hardware failure or system instability. The problem could be the memory (RAM), hard drive, power supply, graphic card or external devices.

In other cases, overheating could be the main trigger. In addition, a device can also end up acting the same after updating. In this case, the update must have contained some bugs that trigger your device to restart by itself. These are likely the same factors that would cause an iPhone to restart automatically. Read on to learn what to do if your iPhone XS Max keeps rebooting after updating to iOS version 12.1.4.

When Apple confirmed the dreaded Group FaceTime bug transpiring on certain iPhone variants, they promptly developed and pushed a dedicated fix patch to address a widespread problem. And so the iOS 12.1.4 was officially rolled out. While many people benefit from implementing the latest update on their respective iOS devices, some iPhone XS Max owners aren’t lucky enough as they ended up facing another annoying issue. Reports have it that some people are complaining about their phones that would just restart even when not triggered. This turned out to be among other post-iOS update issues to deal with. Read on to learn how to solve this iOS problem temporarily or permanently.

What to do if your iPhone XS Max keeps rebooting after installing iOS update?

Considering the fact that the problem started after installing the latest iOS update on your iPhone XS Max, your options are somehow limited. Highlighted below are a few recommended procedures and potential solutions for you to refer to when needed. Start whenever you’re all set to troubleshoot your device.

1st solution: Force restart.

If it has just occurred on your iPhone to reboot automatically, then it could be just due to a minor system glitch or an app that has gone rogue from the update. The simplest initial solution to try when dealing with minor post-update flaws would be a forced restart on the phone. Here’s how it’s done:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Then, press and hold the Power button on the side of your iPad and then release when the device restarts.

Performing a forced restart abruptly ends bad apps and clears out corrupted apps and files from the internal memory that might have destabilized system functions. This process does not affect saved information on the phone memory, so you don’t need to create backups.

2nd solution: Install pending app updates.

Apps that would usually go rogue from an update are those that aren’t updated. This often occurs if the app is no longer compatible with the latest platform. To solve the problem, installing all pending app updates on your iPhone XS Max could help. Here’s how it’s done:

  1. From the Home screen, tap App Store.
  2. From the App Store main screen, scroll down to the bottom and then tap on the Updates tab. Wait for a few seconds to view the list of all apps with pending updates.
  3. Tap the Update button next to the name of the app to install pending update for the application.
  4. If multiple app updates are available, then you can just tap on the Update All button on the top-right of the screen to install all app updates simultaneously.

Restart your iPhone when your done updating your apps. If the problem recurs, search for and delete any obsolete apps and files from your device.

3rd solution: Reset all settings.

Settings that were messed up from the update can also cause conflict to system services. This is usually the case if you’ve customized some settings on your device and the update automatically created overrides that yielded to conflicts. To clear this out, you can reset all settings on your iPhone XS Max, to delete all its current settings and then restores the default values and options. Here’s how to do this:

  1. From your Home screen, tap on Settings.
  2. Select General.
  3. Scroll down to and then tap on Reset.
  4. Select the option to Reset all settings.
  5. If prompted, enter your passcode then follow the onscreen instructions to all settings reset.

When the reset is finished, your iPhone should restart by itself. Wait until it boots up then you can start enabling individual features that you want to use on your phone again.

4th solution: Factory reset.

Complex system errors often require full system resets. If your iPhone continues to reboot unexpectedly, then your next option would be a factory reset. This will erase everything from your phone system and then restores the factory settings and default configurations. If possible, you can reset your iPhone XS Max through its settings menu. But before you do, back up all your critical information to iCloud for safekeeping. Then continue with these steps when ready:

  1. From your Home screen, tap on Settings.
  2. Select General.
  3. Scroll down to and then tap on Reset.
  4. Select the option to Erase all content and settings.
  5. Enter your device passcode when ask to proceed then follow the onscreen instructions to confirm factory settings reset.

Alternatively, you can factory reset your iPhone XS Max in iTunes if the above procedures could not be completed due to random reboots.

To reset your iPhone through iTunes, you will need to use a computer that has the latest version of iTunes apps installed. Then connect your iPhone using the USB/Lightning cable to get start syncing.

5th solution: Recovery mode restore.

If the problem isn’t solved by a factory reset, it’s likely due to a fatal system error that needs more advanced solution. As your next option, you can try restoring your iPhone XS Max in recovery mode. This will put your device in a recovery state and allows you to repair system errors through iTunes. To get started, connect your iPhone to the computer using the Apple-supplied USB cable or Lightning cable. After connecting your iPad to the computer, enter recovery mode with these steps:

  1. Press and quickly release the Volume Up button.
  2. Next, press and quickly release the Volume Down button.
  3. Then, press and hold the Side/Power button until you see the Connect to iTunes screen. This means that your iPhone has entered recovery mode.
  4. When you see the option to Update or Restore, choose Update if you want to restore without deleting files. Doing so will prompt iTunes to start downloading the latest software for your device. If you opt to restore from a previous iOS backup, then select the option to Restore.

Usually, the standard recovery mode restore process takes 15 minutes to complete. If it exceeds the 15 minute margin, your device may exit recovery mode. Should that happens, just let iTunes finish downloading the software for your iPhone and then go back to the first steps to enter recovery mode again and finish restoring iOS.

6th solution: DFU mode restore.

The last form of system restore you can do on your iPhone would be a DFU mode restore. This puts your device in a state that allows it to communicate with iTunes even when the system is totally ruined. If the update happened to corrupt your phone system and you’ve already tried all the above procedures but to no avail, performing a DFU mode restore would be the last option for you to try on.

To do this, you will need to secure a Windows or Mac computer that has the latest version of iTunes app and runs on a compatible OS with that of your iPhone XS Max. Once you have the equipment, plug your iPhone into the USB port using the supplied Lightning cable. Then continue with these steps to put your iPhone XS Max in DFU mode and restore iOS through iTunes:

  1. Quickly press and release the Volume Up button, then quickly press and release the Volume Down button. Finally, press and hold the Side/Power button until the screen turns completely black.
  2. As soon as the screen turns goes black, press and hold the Volume Down button while you keep holding the Side/Power button.
  3. After 5 seconds, release the Side/Power button but continue to hold the Volume Down button until your iPad shows up in iTunes on your computer.
  4. When your iPad Pro appears in iTunes, you can release the Volume button because your iPad is already in a DFU state and all set for an ultimate system repair.

Follow the rest of the instructions or command prompts in iTunes to finish repairing and restoring your iPhone XS Max back to its normal state. You may have to consider downgrading iOS at this point.

Still having automatic reboots on your iPhone XS Max?

Your iPhone XS Max might have obtained some hardware damage prior to the update and that the symptom had just coincidentally occurred following the iOS 12.1.4 update implementation. In this case, your device needs service. You then can take your phone to an Apple-authorized service center nearby and ask a technician to run some test or hardware assessment. If hardware damage is present, then iPhone repair is necessary.

If there’s no problem with the iPhone’s hardware components but automatic reboot continues, escalate the problem to Apple Support. This could be a major system bug that requires immediate patch.
