TL;DR ✨

Do not buy an iPhone that is still linked to the previous owner's Apple Account. It is not enough for the phone to turn on or for the seller to know the screen passcode; the device must be erased, removed from Find My, and must not request the previous owner's credentials during setup.

For a device you legitimately own, use Apple Account recovery, remove it through Find My, or contact Apple with proof of purchase. “Bypass” utilities do not transfer ownership and introduce security and legal risks.

From the archive

The original 2014 article described a technical bypass for an iPhone 4 running iOS 7.1.2. That procedure has been removed: it was obsolete, circumvented an anti-theft control, and did not help today's reader solve the underlying problem safely.

How to Avoid Buying an iPhone Locked to Someone Else

With a used iPhone, a scratched display or tired battery is not necessarily the worst surprise. A device that remains linked to the previous owner's Apple Account is far more serious. After an erase or restore, it asks for that owner's credentials and cannot be activated normally by the buyer.

This protection is called Activation Lock and is part of Find My. Its purpose is to reduce the value of a lost or stolen device to anyone who does not control the owner's account.

What to Check Before Paying

Perform the check while the seller is still present, not after opening the parcel at home.

  1. The seller must unlock the device and sign out of their Apple Account.
  2. The phone must be erased completely, rather than merely having its photos and applications deleted.
  3. Start the setup process and confirm that it does not request the previous owner's account.
  4. The handover is complete only when the Hello screen appears and the phone can be configured as a new device.

The phone still requests the previous owner's account

Do not complete the purchase. Return the device to the seller and ask them to remove it from their account. A promise that it can somehow be bypassed later is not a solution.

The screen passcode alone is not sufficient. Nor is an invoice from someone who cannot establish the phone's origin. For a purchase by post, use a payment method that permits a dispute or return and consider recording the unboxing and first startup.

When the Previous Owner Is Not Present

The previous owner can remove the device remotely through Find My or iCloud on the web. They first erase it and then remove it from their device list. This turns off Activation Lock so that the buyer can activate it with a different account.

If the seller refuses to cooperate, stops responding, or claims not to know the account, treat the phone as unverified. Paying another party for “service unlocking” usually increases the loss rather than resolving it.

When the Phone Is Genuinely Yours

A legitimate owner can:

  • recover the password or identify the Apple Account previously used,
  • enter the account or device passcode on the Activation Lock screen,
  • remove their device through iCloud Find Devices,
  • contact the administrator for a company- or school-owned device,
  • submit an official Apple support request with valid proof of purchase.

The document should clearly connect the device to the purchase. A photograph of the phone, its box, or knowledge of the IMEI may not by itself prove ownership.

Why a “Bypass” Is Not a Solution

Older guides often relied on DFU mode, modified binaries, or unknown Windows utilities. Even when a historical trick exposed part of the operating system, it did not mean that the device had been properly transferred to a new owner.

Such tools have several problems:

  • they may contain malware or steal credentials,
  • they often work only with one obsolete model and system combination,
  • the lock may return after a restore or update,
  • some phone features may remain unavailable,
  • the procedure may conceal the origin of a lost or stolen device.

The meaningful outcome is not merely reaching a home screen. It is having the device properly removed from another person's account and activated under the new owner's account.

Practical Checklist

  • [ ] The seller unlocked the phone in front of the buyer.
  • [ ] The device was signed out of the Apple Account and erased completely.
  • [ ] Setup does not request the previous owner's credentials.
  • [ ] The IMEI or serial number matches the device and purchase document.
  • [ ] The buyer has a receipt, seller identification, and a route for return or complaint.
  • [ ] The phone can be activated with the buyer's account before final handover.
