Before you begin. This procedure is general reference information, not professional advice. Equipment varies by manufacturer, model, and year. Always follow the documentation supplied with your equipment — where it differs from this page, follow the manufacturer. Verify that you have the tools, the working conditions, and the ability to do this task safely. If anything is unclear, if the equipment is damaged, or if the task exceeds your experience, stop and use a qualified professional. You are responsible for your own safety and for the outcome.

Summary
Almost everyone does this in the wrong order. You wipe the phone first, feel organised about it, and hand over a device that is still welded to your account — and now neither of you can clear it, because the only thing that unlocks it is a password the new owner will never have. The wipe is not the part that releases the phone. Taking the account off it is. That has to happen while you are still signed in, on a phone that still has your data on it, which feels backwards and is the entire reason people get it wrong.
The two platforms do not agree on how this works, and there is no single sequence that covers both. Apple wants you to sign out of your Apple Account first and then run Erase All Content and Settings, and Apple's own documentation states that the erase is what switches Activation Lock off. Google is blunter: remove every Google account from the phone as a separate operation, then go back into Settings and start the factory reset. Google states plainly that a protected phone which is reset with the account still on it cannot be used at all without a Google Account that was already synced to it.
This page gives both sequences, in the order each maker publishes them, and then gives you the one check that actually proves it worked — the first screen the phone shows when it restarts. It does not give you the exact menu path to the factory reset on your particular Android phone, because Google does not publish one either; it tells you to go to your phone maker's own support site, and so does this page.

Terminology
This page uses one term for each item and holds it throughout, as ASD-STE100 requires. Equipment sellers and other guides use the names below for the same parts.
- factory reset
- Also called: hard reset, master reset, wipe the phone, format the phone, erase all data, how to wipe my phone before selling it
- Activation Lock
- Also called: iCloud lock, apple lock, icloud locked iphone, iphone locked to owner, activation locked
- device protection
- Also called: factory reset protection, FRP, frp lock, google lock, google account lock, asking for previous google account
- Erase All Content and Settings
- Also called: erase iphone, reset iphone to factory settings, wipe iphone, erase this iphone
- Apple Account
- Also called: Apple ID, apple id account, icloud account, itunes account
When to use a professional
Stop if the phone asks for the account of a previous owner. Only that owner can release the phone. Apple states that a device stays linked to an account until the owner removes it. Speak to the previous owner and ask for the account removal.
Stop if you cannot get the password for the account on the phone. Apple and Google both refuse the erase without it. Speak to Apple Support or to Google support about account recovery.
Stop if a used phone shows a locked screen at the first start. Apple states that you must not take ownership of a locked iPhone. Give the phone back to the seller.
Stop if the phone is a company phone or a school phone. An administrator controls the erase on a managed phone. Speak to your administrator.
Common questions
Do I sign out of iCloud before or after I erase the iPhone?
Before. Apple lists the sign-out ahead of the erase in its own sequence, and that is the order this page follows. Apple also states that running Erase All Content and Settings turns Find My and Activation Lock off, so on a current iPhone the erase itself does release the device. Signing out first is still the documented order and it costs you nothing, because it is the step that protects you if the erase is interrupted or if the phone is later wiped by some other route. Do it in the order Apple publishes it.
I already factory reset my Android phone and now it asks for the old Google account. What can I do?
You need a Google Account that was already added and synced to that phone before the reset, and you need its password. Google states that any previously synced account will do, but an account that was only ever used as a guest will not. If it was your account, recover the password through Google's sign-in help and use it. If it was somebody else's phone, only they can clear it — no setting on the device will, and that is deliberate. This is the exact outcome the account-removal step exists to prevent.
Why doesn't this page tell me the menu path to factory reset my Samsung or my Motorola?
Because Google does not publish one and neither will we. Google's own article says that on most phones you reset through the Settings app and then directs readers to their manufacturer's support site for device-specific instructions. Android manufacturers move that menu around, so a path printed here would be right for some phones and quietly wrong for others. The Settings, System, Reset options route in the steps is the common one; if your phone does not show it, your maker's support site has the real answer.
Is deleting my photos and apps by hand the same as erasing the phone?
No, and on an iPhone signed in to iCloud it can be worse. Apple warns that manually deleting items while you are logged in to iCloud permanently removes them from iCloud servers and from every device connected to that account — so you can destroy the copy on your new phone while trying to clean the old one. Back up first, transfer to the new device, then use the erase. Manual deletion also leaves the account on the phone, which is the thing that locks it.
What happens to my eSIM and my phone number?
Apple asks during the erase whether to erase the eSIM profile as well, and the right answer depends on what you are doing. If you are selling the phone and the number is moving to a new device, Apple says to choose the option that erases the device and the eSIM profile. If you are keeping that number on this phone, do not erase the profile, because your carrier will have to issue a new one. Physical SIM cards and memory cards should simply be taken out before handover.
How do I check that the wipe actually worked before I hand the phone over?
Start the phone and look at the very first screen. Apple says an iPhone is ready for a new owner when you see the Hello screen; if you see an iPhone Locked to Owner screen, Activation Lock is still on, and if you see a passcode or home screen the erase never ran. On Android, a setup screen that asks for a Google Account you recognise means device protection is still active. This single check catches nearly every version of this mistake.

Revision history
Current version 1 · updated 2026-07-29 · next review due 2027-07-29
- v1 · 2026-07-29First draft. Built from Apple and Google support documentation opened by direct HTTPS fetch on 2026-07-29: Apple 'What to do before you sell, give away, or trade in your iPhone or iPad' (Apple Published Date May 29, 2026) and 'Activation Lock for iPhone and iPad' (April 29, 2026); Google 'Reset your Android device to factory settings', 'Help prevent others from using your device without permission' and 'Reset your old Android device', none of which carry a published date. The Android reset route is published as a consult-manufacturer instruction because Google itself directs readers to the phone maker's support site rather than publishing one route. The legacy Apple number 102491, widely cited for Activation Lock, redirects to an unrelated Mac article and is recorded under rejected rather than cited.
