TL;DR: To fix an iPhone 15 Pro Max stuck on the Apple logo after an OTA update, you must force restart the device, connect it to a computer, and use Recovery Mode to "Update" the iOS firmware via an IPSW file. This reinstalls the operating system without erasing your personal data.
What Is a Bootloop?
A bootloop occurs when an iPhone's core software becomes corrupted—often during a failed update—causing the device to continuously restart or freeze indefinitely on the white Apple logo screen.
Why It Matters
The iPhone 15 Pro Max is Apple's flagship device, but it is not immune to software failures. When an Over-the-Air (OTA) update via the Settings app is interrupted by a drop in Wi-Fi, low battery, or critically low storage space, the iOS file system breaks. At this point, the phone cannot boot. If you don't use the correct recovery method, you risk permanently erasing all your photos, texts, and app data.
How It Works: Recovery Mode vs. DFU Mode
To bypass the broken operating system, you have to use a low-level hardware interface.
Recovery Mode (Data Safe)
Recovery Mode tells your computer to inject a fresh iOS IPSW file over the broken system. If you select "Update" in Finder/iTunes, it only replaces the core OS files and leaves your personal data untouched.
DFU Mode (Data Wipe)
Device Firmware Update (DFU) mode is a deeper restore that completely formats the NAND storage chip before installing iOS. This will fix the bootloop, but it will erase 100% of the data on the phone. Only use this if Recovery Mode fails.
Practical Steps to Fix the Apple Logo Issue
Follow these steps precisely. You will need a USB-C to USB-C cable and a computer.
- Step 1: Perform a Force Restart. Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Side button until the screen goes black and the Apple logo reappears. If it boots up normally, you're done. If it gets stuck again, proceed to Step 2.
- Step 2: Enter Recovery Mode. Connect the iPhone to your Mac or PC. Perform the Force Restart sequence again, but this time, keep holding the Side button even after the Apple logo appears. Release it only when you see the "Connect to Computer" icon (a laptop and a cable).
- Step 3: Choose "Update" (Crucial). A prompt will appear in Finder or iTunes stating "There is a problem with the iPhone that requires it to be updated or restored." Click Update. Do not click Restore.
- Step 4: Wait for the IPSW Download. Your computer will automatically download the latest iOS IPSW file. If the download takes longer than 15 minutes, the iPhone will exit Recovery Mode. Simply repeat Step 2 once the download finishes.
Alternative: Fix Without Data Loss (Using Third-Party Software)
If iTunes throws an error (like Error 4013 or Error 9), you can use dedicated iOS recovery software. Programs like Tenorshare ReiBoot or Wondershare Dr.Fone are specifically designed to repair the iOS system partition without erasing user data, bypassing common iTunes restrictions.

Common Mistakes
The most devastating mistake users make is clicking "Restore" instead of "Update" in iTunes. Clicking "Restore" will immediately erase the iPhone 15 Pro Max. Always try updating the software first to save your data.
