iPhone Troubleshooting & Recovery
Section updated .
iPhone recovery has a fixed order, and following it matters more than knowing any single trick. For a dead phone: force restart before anything else, then charge for an hour, then recovery mode. For a missing phone: Lost Mode first, then contact your carrier, then change your Apple Account password. For a new phone: restore from backup before signing into anything else. Doing these out of order is what turns a recoverable problem into data loss.
Troubleshooting advice on the internet fails in a specific way: it lists ten things to try without saying which order to try them in, or which ones destroy data. Erasing an iPhone will absolutely fix a software problem, and it will also cost you anything not backed up, which is why it belongs at the end of a list rather than the middle.
Every guide in this section is written as a sequence with a stopping rule — do this, check that, and if it worked, stop. The destructive steps are labelled as destructive before you reach them.

Read the guide →How to work through this section
Match the guide to the symptom, then follow it top to bottom without skipping. A phone that shows nothing on screen goes to will not turn on, where a force restart resolves the large majority of black screens. A phone you cannot find goes to lost or stolen, which is time-sensitive: the first ten minutes decide whether the finder gets a locked brick or your accounts. A replacement device goes to restore from backup. Connectivity problems go to Wi-Fi and cellular, where the ordering matters because resetting network settings clears every saved Wi-Fi password.
Frequently asked questions
How do I force restart an iPhone?
On iPhone 8 and later, press and release Volume Up, press and release Volume Down, then press and hold the Side button until the Apple logo appears, which can take fifteen seconds or more. It does not delete anything and is the correct first step for an unresponsive phone.
What is the first thing to do when an iPhone is stolen?
Open Find My from another device or iCloud.com and put the phone into Lost Mode, which locks it, displays a contact message, and suspends payment cards. Do that before calling your carrier, because it takes seconds and works even if the phone is currently offline.
Should I erase a lost iPhone remotely?
Only once you have given up on recovering it, because on current iOS an erased device still shows in Find My but you lose the ability to see updated locations in the same way. Lost Mode already blocks access to your data, so erasing is a last step, not a first one.
Does restoring from a backup bring back everything?
It restores your apps, settings, messages, and app data, but not content tied to accounts you must sign into again, and not items excluded from the backup. Passwords in iCloud Keychain and photos in iCloud Photos come from those services rather than the backup itself.
Does resetting network settings delete my data?
It does not touch photos, messages, or apps, but it does erase every saved Wi-Fi password, VPN configuration, and paired cellular setting. Have your Wi-Fi passwords available before you do it.
