Hello everyone, Lin Fei to answer the above questions, Apple refurbished machine to identify how to transmit information, Apple refurbished machine identified a lot of people do not know, now let's take a look!

How does iPhone4 identify the refurbishment machine?

Due to the invalidity of iPhong4s, the time of listing in mainland China has not been determined, resulting in a large increase in the price of iPhone4 recently, followed by a large number of refurbishment machines on the market. So how do you tell if your iPhone4 is not a refurbishment machine? Of course there is a way, and it's very simple. Here's how iPhone4 identifies the refurbishing machine. It is important to note, however, that serial number recognition only applies to the iPhone4 of 16GB and 32GB. The new 8GB version of iPhone4 temporarily supports query identification on the official website because of the new serial number format.

1. The Secret in numbers

Turn on Settings-General-about this machine, we can see all the information in the machine. One of the settings in the machine is the serial number, which is very important for iphone4. A seemingly random combination of numbers actually reveals iphone4's date of birth.

The serial number on this machine is 5k1175. We just need to look at the third, fourth and fifth digits. The third table shows the year of production of the mobile phone, and the fourth and fifth tables show the number of weeks in which the machine is produced. If this machine is the 17th week of 11 years, we can roughly calculate how long the machine you bought has been produced. So the third number is 0, which of course means that the machine was made in 2010. If you find that the phone you buy is still a long way from the date of production, and even the third, fourth and fifth serial numbers of some fake phones are not numbers but English letters at all, it's time to think about whether you bought a refurbished machine or a fake.

two。 Digital reminder

Under the dialing interface, press the serial number of "* # 06 #" in turn. This set of numbers must be exactly the same as the numbers on the slot of the mobile card in order to verify the identity.

3. The words on the back cover

4 iphone 4 is stamped with the logo information, but if you compare it carefully, you will find a difference. Machines with Chinese characters say they are authentic from the mainland, while machines with Chinese characters say they are authentic from Hong Kong.

I just went back to the search interface for serial numbers, the model column. If the last two letters are CH, it means that the machine is authentic mainland China, and if it is ZP, it means that the machine is made in Hong Kong. If you find that the back cover mark and serial number are wrong, be careful.

4. The message in the screw

4 iphone 4 the only two screws to observe carefully, some are cross-shaped, some are plum blossom-shaped. Apple's early product was Phillips screws, which were easy to refurbish. Later products all use plum blossom thread screws, which are not suitable to find. The plum blossom screws are new and polished without any scratches. These two screws can also be a breakthrough for you to identify the refurbished machine. If what you buy is a new machine, but it is actually a Phillips screw, there must be a problem. In addition, it is not difficult to see whether the screw has been passivated or polished.

5. activation

Unlike other phones, every new iphone4 needs to be activated. After activation, you can enjoy the one-year warranty provided by Apple, so this activation date has become an important basis for us to identify the refurbished machine. Log on to Apple's website (https://selfsolve.apple.com/agreementWarrantyDynamic.do? Newid=y) enter the serial number to activate, and the third check box shows the expiration date of the machine warranty period. One year is the time when you buy a machine. Because Apple's server is in the United States, it sometimes lags behind, so sometimes you will find that the purchase date is one day earlier, which is normal, and you can rest assured a few days in advance. However, if you buy a machine that is called a new machine, it was activated a month or six months ago. "

Editor's note: when you buy a mobile phone, you are most afraid of buying a new machine. What I buy with hard-earned money is second-hand goods that others have used. I feel very lost when I think about it. Through the tutorials of this article, I believe that all netizens can become experts in identifying refurbished machines. There is one more thing that Bian Shaw needs to remind all of you. Be sure to read and touch it carefully before you buy a mobile phone. If you find any problems, you must ask the store immediately. If necessary, you can also ask for online inquiry and identification. If the shop owner doesn't cooperate, be careful.
