If you encounter an activation lock when you forget your Apple ID and password, it's really crazy. At this point, the first thought that flashed through most people's minds was: "untie it." Since the mobile phone is made by Apple, I'm sure I can unlock it. To this end, Xiaoyu also called Apple Customer Service Center (tel: 400-666-8800 or 400-627-2273), but the result was somewhat unexpected.
E-mail from Apple
Xiaoyu introduced the locked state of the mobile phone to the customer service staff: "The machine is iPhone 5, and it is activating the screen, but it is prompted to enter the Apple ID and password, both of which have been forgotten." The customer service staff asked about the mobile phone, including the model, IMEI and the owner's name. After confirmation, another email was provided, which was an email to retrieve the Apple ID. The customer service staff said that this is the only way for users to operate.
Retrieve Apple ID operation
Simply take a look at this webpage, which is actually the login page of Apple ID, and there is an option to "retrieve your Apple ID" at the bottom right. After clicking enter, you need to fill in your name and four email addresses. It can be seen that the retrieval of Apple ID is to use two key information during registration to determine which mailbox to use for registration, so that after exclusion and filtering, the password can be modified according to ID and mailbox. This method seems reasonable, but before that, most people will try familiar accounts, and the people who can get this far are basically the careless and lazy users mentioned above.
Retrieve Apple ID operation
In the case that China Merchants Bank failed, Xiaoyu asked if he could take his mobile phone, purchase invoice and ID card to the flagship stores of Apple such as Xidan and Wangfujing. The answer given by the customer service staff is very affirmative, and the ID and password cannot be retrieved in the specialty store and after-sales. After that, the customer service staff gave the final solution, that is, providing copies of mobile phone purchase vouchers (receipts or invoices issued by specialty stores), SN code labels of packaging boxes, ID cards, warranty cards, three-guarantee vouchers and other materials, and submitting them to the relevant verification team of Apple for verification, and the purchase vouchers must be certified by Apple or issued by Apple officials. Post-paid tickets and some dealer tickets cannot be used as verification materials, and the unlock id and password will be provided after confirmation.

In this regard, Xiaoyu asked whether the verification team was in China, how to provide information and how long it would take to unlock it. The customer service staff only answered three "unclear" questions. Later, I asked about the unlocking of mobile phones purchased in foreign countries and Hong Kong, and the customer service staff replied that "unlocking service cannot be provided."

After a brief analysis, the so-called information provided to the verification team should be submitted to the relevant data department of Apple for verification. It is also reasonable that domestic specialty stores and after-sales stores cannot be unlocked. After all, Apple has always attached great importance to the security of user data, and its related databases are inaccessible to specialty stores and after-sales personnel. This kind of question involving ID and password will definitely be cautious. In other words, it is almost impossible to seek to unlock Apple, at least without these credentials. Only iPhone 4 can realize hardware decoding.
What can maintenance personnel do for the problems that Apple stores can't solve? A Liang said that activating the lock is also a difficult problem in the current maintenance industry, which cannot be solved by soft solutions such as software and brushing machines. The only feasible thing is hardware decoding. At present, only iPhone 4 can realize hardware decoding activation lock. The principle is simple. The locking basis of the activation lock is the IMEI and SN code of the machine itself. If these two codes can be replaced, they can be unlocked naturally. IMEI and SN codes are stored in baseband chips and baseband fonts. Replace these two chips, and then write a set of codes. Let's take a look at the specific maintenance process:
Maintenance process
1. Take apart and take out the motherboard of iPhone 4. (There are many iPhone 4 disassembly tutorials on the Internet for reference. )

2. What needs to be replaced are baseband chips and baseband fonts. Remove the shield with an air gun first, and then remove the chip. Please refer to geek repair: how to repair the damaged font of brick machine? 》)

3. Put the baseband chip and baseband font back on the motherboard. Please refer to geek repair: how to repair the damaged font of brick machine? 》)

4. Write the available IMEI and SN codes into the newly installed baseband chip and baseband font. At this time, professional numbering staff and software are needed.

5. After the above operations are completed, install the motherboard for testing and startup. Apple ID and password are not required for activation at this time.

Although the whole step is simple to say and the reason is easy to understand, the actual operation requires rich experience, and a little carelessness may damage the motherboard. If you have no relevant experience, it is best to ask professionals to assist in the operation. In addition, this method is only applicable to iPhone 4 at present, and there is no good cracking method for iPhone 4S, iPhone 5, iPhone 5c and iPhone 5s. I believe it will be gradually improved in the future.
I have provided two methods, you can choose. As said downstairs, if the mobile phone is not stolen, then take the voucher to the mobile phone shop to brush it, because I think this method is more reliable after all! !
