Symptoms
- Setup screen asks for an Apple ID or Google account you don't recognize
- Message says the device is linked to another account
- Can't proceed past a specific setup screen
- Phone was purchased used or received secondhand
Likely causes
- CommonPrevious owner didn't remove the device from their account before selling or giving it awayThis anti-theft feature stays active until the original owner signs out or removes the device remotely.
- PossibleDevice was reported lost or stolenIf the phone wasn't obtained legitimately, this lock is intentionally designed to prevent it from being used.
- PossiblePrevious owner forgot their own account credentials to remove the lockEven a well-intentioned seller may struggle to complete this step if they've forgotten their login.
What to do
- Contact the person you got the phone from and ask them to remove the device from their account (via 'Find My' or their account's device list) and sign out.
- If they no longer have access to their old account, they'll need to go through that account provider's password recovery process first.
- If you have a receipt or proof of purchase, some manufacturers offer a request process to unlock as the legitimate new owner.
- Never pay a third-party 'unlocking service' for this, since it typically doesn't work and can be a sign the device isn't legitimately obtainable.
- If you can't get the previous owner to cooperate and there's no receipt, treat this as a sign the device may not be safe to use, since it can never fully unlock without their account.
- Contact the manufacturer's official support to check what proof-of-ownership options exist for your specific situation.
When to call a pro
If the previous owner is unreachable and you have no proof of purchase, contact the manufacturer directly; never use unofficial unlocking services, which don't legitimately work and can indicate a stolen device.
