Quick Fix: Reset your iPhone completely by going to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. You’ll need your PIN and Apple ID password to confirm.
What actually happens when you try to “remove” an iPhone update?
Apple doesn’t give you a straightforward “uninstall” button for iOS updates like you’d find for apps. When an update installs, it overwrites the previous version at the system level. Your real options are limited to: wiping the device clean, rolling back to a signed older version (if Apple still permits it), or deleting the leftover update file before it finishes installing. Think of it this way—updating iOS is more like renovating a kitchen than installing a new app. You can’t just hit “undo.” You can demo the whole room and start over, move back into the old kitchen temporarily, or just live with the dust for a while.
How do I do a full reset to remove the latest update?
Go through Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. You’ll need your passcode and Apple ID password to confirm. This nukes everything and reinstalls the iOS version that shipped with your phone. It’s drastic, but it guarantees a clean slate with the original firmware.
I tried the full reset and it didn’t help. What else can I do?
Try these three approaches instead:
- Delete the update file before it installs
- Head to Settings > General > iPhone Storage.
- Look for the iOS update entry—usually at the top.
- Tap it, then choose Delete Update. This removes the installer so the next update downloads fresh.
Only works if the update hasn’t already finished installing.
- Roll back to the last signed iOS version
- Check ipsw.me to see which iOS versions Apple is still signing as of 2026.
- Use a computer with Finder (macOS 10.15+) or iTunes (Windows). Put your device in Recovery Mode:
- iPhone 8 or later: Press and quickly release Volume Up, Volume Down, then hold Side button until recovery screen appears.
- iPhone 7/7 Plus: Hold Volume Down + Side (Sleep/Wake) until recovery screen appears.
- In Finder/iTunes, choose Restore iPhone while holding Option (Mac) or Shift (Windows). Pick the IPSW file for the older iOS version you want.
- Let the restore complete. You’ll land on the older version—provided Apple still signs it (usually about two weeks after a new release).
- Restore from a Time Machine or Windows backup
- Plug your iPhone into the computer with the backup.
- Open Finder (Mac) or iTunes (Windows) and select your device.
- Choose Restore Backup, pick the backup from before the update, and wait.
- After restore, your phone boots into the iOS version that was on the backup.
How can I prevent getting stuck with a bad update in the future?
Follow these four habits to keep your options open:
- Back up before every update — Use iCloud or a computer backup so you always have a clean snapshot of the previous iOS version.
- Wait a few days before updating — Give Apple’s release notes and early adopter forums time to surface bugs like battery drain or app crashes.
- Keep an old iPhone as a “restore device” — If you’ve got an old model gathering dust, keep it on the last major iOS version Apple signed for that hardware. It’s your emergency downgrade lifeline if something goes wrong.
- Turn off automatic updates — Go to Settings > General > Software Update > Automatic Updates and toggle it off. You decide when updates arrive, not Apple.
