iPhone ติด Activation Lock เข้าไม่ได้

Refer to https://support.apple.com/108934 There are only two ways to remove a lock:

#1 If you have the necessary information, you or the signed in owner can do this yourself by simply signing in with the owner account and password information and doing as instructed in the above article. If you use this method and this is a new device to you, follow unlocking by doing as outlined in https://support.apple.com/109511 or https://support.apple.com/HT201065 . If you do not have the required information then you can try method 2 —>

#2 Apple can completely reset a device if a person can provide sufficient evidence of valid ownership. Read the requirements and steps for an Activation Lock support request at: https://al-support.apple.com/#/additional-support and links at the bottom right for the type of service requested. Apple says they “may” require "proof of purchase documentation” and that you need “proof of ownership documentation”, but does not detail what currently constitutes proof other than it “must include the product serial number, IMEI or MEID.” User reports on this community and chat with Apple indicate that typically Apple will absolutely require, and ONLY accept, an original receipt issued by Apple or an Apple Authorized Reseller. Presumably this is the only kind Apple can authenticate against fraud since Apple is not involved in third party sales. Apple recommends that you "Keep your receipt after you buy an Apple device" --> https://support.apple.com/HT202711

Note that the device cannot have Lost Mode set on it or be a managed device. If your device has been taken over by you having entered a scammer’s Account then the scammer has likely set Lost Mode and the device is lost to you.

You do NOT have to be the “original” owner. In the case of removing the lock with the correct information, it can be anybody who knows the currently signed in account information. In the case of asking Apple to unlock it, as long as you have the original Apple receipt (which may well not have any personally identifying information on it) you are okay. Apple confirmed this in a conversation.

If Apple resets the device this will give you access to the device but won't restore access to the account used to lock it. There is nothing that can be done to expedite an Activation Lock request.

If you cannot get the device unlocked then read this section from the very bottom of https://www.apple.com/shop/trade-in :

"Does Apple offer recycling?

Yes. Apple Trade In lets you recycle any Apple device (including devices from Apple-owned brands) at any Apple Store and on https://www.apple.com/ for free."

It sounds as if you logged out of your Apple Account and into another person's Apple Account ("someone I know, whom I can no longer contact."). That person then proceeded to "disappear", leaving you high and dry.

This was a very bad mistake, one that may have catastrophic consequences. Both in terms of permanent loss of use of your phone, and in terms of exposing your data to this other person.

Signing Out of Your Apple Account and Into Someone Else's Account Could Have Catastrophic Consequences – Apple Community

If the person who "disappeared" has placed your phone into Lost Mode – as is typical in these cases – it is pretty much indistinguishable from a phone that belongs to this other person, and was lost by, or stolen from, them. So with the phone in Lost Mode, even an original receipt from Apple or an Apple Authorized Reseller likely will not be enough proof of ownership to convince Apple to release an Activation Lock. As for the box and the charging cable, those things would not be considered sufficient proof that you were the owner even if the phone was not in Lost Mode.

iPhone Stuck on Activation Lock – Unable to Access

Over the past six days, I have experienced something that has left me deeply disappointed with Apple for the first time. Their approach to providing assistance shows a complete lack of genuine concern for the user's actual problem. I have spoken with several Apple Support representatives, all of whom responded like scripted bots, hiding behind "privacy and security policies." It seems to me that the very first group of people Apple needs to focus on—and ensure truly understands these issues—is their own staff.

My iPhone is stuck on "Activation Lock" due to a situation involving someone I know, whom I can no longer contact.

Today marks the sixth day I have been dealing with Apple Support regarding this issue. Every time I follow up, they ask me to resubmit the same information and photos, opening a new ticket—over and over again for six days straight. Even though I speak to different representatives, the response is identical every single time.

There has been absolutely no progress. The support staff remain frustratingly calm, offering suggestions that seem to require no real thought or engagement with my specific situation. I don’t even have access to the iPhone itself, which means I cannot complete 2FA (two-factor authentication), receive OTPs, or even answer calls.

I have received zero meaningful help. I have provided every piece of information requested. I have owned this device since it was first activated; I’ve provided the requested proof, and I even have the shop owner who sold it to me—the person who tested it right in front of me—ready to provide verification. Apple is welcome to investigate, but everything I’ve offered has been treated as useless. I have received no assistance whatsoever.

Every time, I am told that these measures are in place to "protect user privacy and security." Yet, I have provided every form of proof—I was the one who first activated the device, I have the receipt, the original box, and even the unopened charging cable; the data on the device is mine—so, am I not a "user" too? And this is what Apple has been "protecting" me from for the past six days.

I don’t have my iPhone, and so much of my life is tied to it. I barely remember any of my app passwords because I’ve always relied on Face ID.

I can’t access my iCloud or Apple ID at all, because I don’t have the iPhone to confirm the 2FA (two-factor authentication) prompts.

I’m locked out of every single one of my email accounts—they all require passkeys, OTPs, or 2FA. No matter how hard I try, I always end up at a dead end; even when I borrow someone else’s phone to attempt the recovery process, it’s impossible to proceed.

I can’t access my banking apps, my emails, or my work-related apps. Meanwhile, Apple keeps insisting that they are "protecting" me—yet I don’t even have a device to call my mother and ask if she’s had anything to eat today.

I’ve pleaded for some understanding, but nothing has been done. Yesterday, I received alerts for all five of my email accounts warning of critical security risks; one of them has already been compromised. I can no longer access my Apple ID or iCloud using my phone number.

Right now, I’m just sitting here watching my data being compromised, with absolutely no help in sight. I have no idea what information has already been leaked, or how sensitive that data might be.

There is so much more I want to say... but I’m just too exhausted to type any more.
