How to Factory Reset Your iPhone and What to Watch Out For | Key Points to Know Before Buying a Used Device

"My iPhone is locked and I can't use it," or "I want to initialize it but I don't know how." Do you have these concerns?

When selling, buying, or transferring an iPhone, "initialization (reset)" is essential. However, if you forget your passcode or the device is unstable, you might not be able to initialize it using the usual method, requiring a forced initialization.

In conclusion, forced initialization is safe if performed correctly, but without knowing the proper preparations and precautions, data may not be restorable, or the device may become unusable due to Activation Lock.

This article explains how to perform a forced initialization on an iPhone and the important points to note. It also covers how to check if a used iPhone has been initialized.

There are two types of iPhone initialization: what's the difference between normal and forced?

What is normal initialization?

This is the method of "Erase All Content and Settings" from the Settings app. If done in conjunction with signing out of iCloud, you can safely dispose of the device.

What is forced initialization?

This is a method of initialization that uses recovery mode by connecting the device to a PC (Mac or Windows) when the device is frozen or the passcode is unknown.

It is done using iTunes (Windows) or Finder (Mac).

Specific steps for forced initialization: necessary preparations and execution method

Pre-preparation

• Prepare a Lightning cable and a PC (Mac or Windows)

• Connect the iPhone to the PC and launch iTunes (or Finder)

How to enter recovery mode (example: iPhone 8 and later)

1. Press and quickly release the Volume Up button

2. Press and quickly release the Volume Down button

3. Press and hold the Side button until the recovery mode screen appears after the Apple logo

Select "Restore" in iTunes/Finder

• Selecting "Restore" will perform a forced initialization of the iPhone, returning it to factory settings.

*All data will be erased with this method. If there is no backup, data cannot be restored.

"Initialized" and "Activation Lock" to be aware of when purchasing a used iPhone

Even if initialized, the lock may remain

Even if it appears initialized, the device cannot be used if the "Activation Lock" linked to the iCloud account has not been deactivated.

How to use after forced initialization? Key points and precautions for re-setup

Apple ID and password input required

Even after a forced initialization, the original Apple ID and password may be required. This is the "Activation Lock."

If purchasing a used device or receiving one as a transfer, it is essential to check if the lock has been deactivated.

Restoration from backup is possible

If you have a backup on iCloud or your PC, you can restore data after initialization. Make it a habit to back up regularly.

Finally

Forced initialization of an iPhone is an effective last resort when you forget your passcode or the device becomes inoperable. However, there are many points to note, such as the need for Apple ID lock confirmation after initialization.

If you are considering a used iPhone, it is safest to choose a "initialized and lock-deactivated" device from a reliable specialist store. At PRODIG, you can find an iPhone with clearly stated condition and specifications, ready for immediate use.
