Start with these three steps
Identify the operation
Write down the exact option used, whether a computer was involved and what appeared afterwards. Keep any repair notes or screenshots that explain the sequence.
Protect older backups
Keep existing backups and archive useful computer copies before making replacements. Record which device and date each backup belongs to.
Check accounts separately
Look for wanted information in the accounts and services you previously used. Check what is actually present before assuming a fresh phone means everything is gone.
Distinguish a settings reset from an erasure
Apple's Reset All Settings returns settings to their defaults without deleting data or media. Erase All Content and Settings is a different operation. A factory restore through a computer also removes the device's information.
If somebody else performed the work, ask which operation completed. A description such as software repair is not precise enough to establish the data outcome. If only settings changed, investigate missing accounts or app views before concluding that the original content was erased.

Why a completed erasure changes the answer
Apple's Data Protection documentation explains that device files depend on encryption keys. Erasure removes key material so the protected files become cryptographically inaccessible. This is more than removing filenames from a directory.
The practical consequence is that an ordinary scan cannot simply undo a completed cryptographic erase. Claims to recover the erased phone's original local contents need to address that limit directly. A useful assessment may establish what happened or locate other copies; it should not promise to recreate destroyed keys.

Search beyond the erased device
Erasing an iPhone does not itself delete its content from iCloud. Check the original Apple Account and any other services you used for photos, documents, contacts or notes. Manually deleting synced items before erasure is a separate event and may have affected those copies.
Also consider saved exports and information shared with other people. Make a short list of wanted items and the places each might exist. This turns a broad search for everything into a set of checks you can complete and verify.

Restore from an existing source deliberately
An existing iCloud or computer backup can be restored to a suitable device. Review its date and contents before choosing it, and preserve any new information created since the reset. Follow Apple's restore instructions once you have identified the appropriate source.
Afterward, check the items you needed. Synced information may arrive separately from the device backup, so returning apps or a familiar Home Screen is not proof that all the original content has returned. Keep a list of what is confirmed, still missing or awaiting download.
If the same iPhone was set up as new after erasure, check the older iCloud backup before letting a new backup replace it. Apple warns that new backups in this situation can overwrite the saved copy. Keep new files separately, such as exports or a separately retained computer backup, while deciding which source to restore.

A realistic view of recovery
- A completed cryptographic erase prevents ordinary recovery of the original protected files from that device.
- A surviving backup or cloud account may hold only part of the information you want.
- If no copy exists elsewhere, this guide offers no guarantee that erased information can be recovered.
