Stop! Protect Your Data Before Proceeding

Latest version of iTunes or macOS Catalina 10.15 and later.

That said, if your last iPhone was a 7 or earlier, get ready for a slightly more complicated button process. Apple hasn't changed the button combination to enter these modes since the iPhone 8, 8 Plus, and X. While your iPhone SE might be brand new, the recovery and DFU processes aren't.

Then it's up to you to use factory settings or get all your data back.

Whether the problem is big or small, both can help bring your iPhone back to life (so long as there's no significant physical damage). It's most useful when the bootloader that recovery mode interacts with is corrupted.įunctionally, your iPhone SE's screen will remain black during the whole DFU process, while that's not the case with recovery mode. Effectively, it will do the same thing as recovery mode, only it goes about it differently, and your data will not be restored automatically. When that's done and all the necessary checks are completed, the filesystem and other variables are flashed - all while trying to keep your data intact.ĭFU mode, or Device Firmware Upgrade mode, is different in that your computer is working directly with the bootrom (SecureROM), which is burned directly into the hardware. It also helps when your iPhone SE is stuck on the Apple logo progress bar at startup, your computer won't recognize the device, or either your iPhone or computer says it's in recovery mode already.Īpple's Finder or iTunes, depending on your computer, communicates with the iPhone's bootloader (iBoot), part of its operating system, to send it the ramdisk and kernel from the IPSW file of the most recent iOS version. Recovery mode is useful when neither of those options worked.

A force restart is necessary when the device's screen remains frozen and the Side button unresponsive. The normal shutdown and start-up procedure is good at fixing minor bugs and glitches you may be experiencing. Force-restarting the device may do the trick, recovery mode is a last-ditch option, and DFU mode is your fail-safe. If your new 2020 iPhone SE is frozen, unresponsive, or won't load the system, and a standard power down and up procedure didn't work, there are few more things you can try.
