Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsIf an iOS 27 update leaves your iPhone unstable or unable to start, use Apple’s recovery options first. Try Update before Restore when a computer offers both; Restore reinstalls iOS and erases the iPhone. Apple’s current recovery guidance explains how to repair or reinstall iOS and then restore a backup, but it does not establish that a previous iOS release can be installed on your device.
Can you roll back to the iOS version you had before?
Apple’s current instructions cover recovery, reinstalling iOS, and restoring a backup. They do not confirm that an earlier iOS version is installable on a particular iPhone at this time. So do not assume that a downgrade is available or install an older firmware file based only on the recovery instructions. If your immediate problem is that the phone will not start, follow the recovery steps below; for a downgrade, check Apple’s current guidance for your specific device and software version.

If your iPhone still starts, try its on-device recovery options
iOS Recovery may appear automatically after an incomplete update or restore, or if the iPhone detects a stability issue. It attempts to resolve the problem and then offers options suited to the issue. Which options appear and what they require can vary:
- Recovery Assistant: attempts to address stability or operating-system launch problems; requires your passcode and Wi-Fi.
- Software Update: requires your passcode and another iPhone or iPad.
- Diagnostics Mode: requires Wi-Fi.
- Erase All Content and Settings: requires your passcode and deletes data on the iPhone.
- Computer Recovery Mode: requires a computer and USB connection.
These actions are not interchangeable: Recovery Assistant attempts a repair, while erasing the iPhone deletes its contents. Before selecting an erase or restore option, make sure you have an available backup if you want to recover stored data.

Use a computer if the iPhone will not start or an update failed
Apple says recovery mode may be needed if the Apple logo has remained on screen for several minutes without a progress bar, a computer does not recognize the iPhone or reports it is in recovery mode, the “Connect to computer” screen appears, or the phone repeatedly returns to Recovery Assistant without resolving the issue.
- Connect the iPhone. Use a USB cable that supports data and is compatible with the iPhone and computer ports. Keep the phone connected. On a Mac, open Finder; on a PC, open the Apple Devices app.
- Enter recovery mode using the sequence for your model:
- iPhone 8 or later, including iPhone SE (2nd generation and later): Quickly press and release Volume Up, then quickly press and release Volume Down. Hold the side button until the “Connect to computer” screen appears.
- iPhone 7 or iPhone 7 Plus: Hold the top or side button and Volume Down together until the “Connect to computer” screen appears.
- iPhone 6s or earlier, including iPhone SE (1st generation): Hold Home and the top or side button together until the “Connect to computer” screen appears.
- Choose Update first, if it is offered and has not already been tried. Follow the computer’s prompts while leaving the iPhone connected. If the download takes more than 15 minutes and the phone exits the recovery screen, let the download finish, re-enter recovery mode, then continue.
- Choose Restore only if needed and you accept erasing the iPhone. Restore reinstalls iOS and erases all data on the device.

Restore your data from a backup after an erase
Once the iPhone is operational and in setup, you can restore from an available iCloud backup or a computer backup. Apple documents iCloud restoration during device setup and computer-backup restoration through Finder on newer Macs or iTunes on older Macs and Windows devices. If the computer backup is encrypted, you need its password. See Apple’s iPhone backup and restore guide.
A backup can require a newer iOS version than the iPhone currently has. For an iCloud backup, Apple says to update the device before restoring. If a computer backup requires a newer version, Apple’s guidance is to complete setup without transferring data, update iOS, erase the iPhone, then set it up again and restore the backup. Follow the relevant prompts in Apple’s guidance for restoring a backup that requires a newer iOS version.
