How Does Part Pairing Work On Apple Devices? | XiRepair

So what's all this talk about pairing parts and serialization? Is it true that your iPhone 15 won't work at all if you replace the parts?

Around schemes to connect the parts with some more conversation and dialogue. I wanted to take the time to clear up the many misconceptions and rumors I've read about OEM parts pairing and serialization. First, let's address the difference between parts pairing and parts serialization as they are two completely different tasks.

A serial number is a unique number that is usually algorithmically generated to identify unique characteristics about a device such as the make, model, date, and/or location where the device was manufactured. Serial numbers play an important role in all our electronics including cell phones, tablets, computers, even your blender has a serial number. Today's smart gadgets consist of many individual components manufactured by different companies. Each individually manufactured component, including screens, batteries, cameras and more often has its own unique serial number. Depending on who manufactures the product, the serial number may simply be a black and white label printed on the component or it may actually be flashed directly onto a small integrated circuit.

Mass production of printed circuit boards and miniaturized ICs has enabled a more secure method for generating serial numbers in chips mounted on the components themselves. Instead of relying solely on a printed sticker or label – which can easily be illegally copied – manufacturers now rely on printed circuit boards and integrated chips to store encrypted serial numbers. Overall this relatively new method of “serialization” isn't bad. This allows original equipment manufacturers to obtain data on the failure rates of specific components and ultimately allows them to select vendors that produce the most successful components. It also allows smart devices to identify when a particular component has been replaced and that's where part of the conversation comes in.

A pair of parts is completely different from the serial number of the individual parts. When in fact Independent repair providers As XiRepair refers to, part pairing often discusses the process of using the OEM's proprietary software to “pair” a new genuine OEM part with the motherboard on a device. During an OEM authorized repair from an independent or authorized Apple service provider, a technician must complete a “system configuration” using Apple's proprietary GSX software to pair the new part with the phone. During “System Configuration” the new serial number on the new genuine OEM part is linked to the logic board on the customer's iPhone. Failure to connect a genuine OEM part will result in an “important message” stating that the software on the phone is “unable to verify” whether the new part is genuine or not. In layman's terms, part pairing is using software to clone a part's serial number from one device to another.

Part pairing has been a common practice among Apple authorized suppliers who have access to the necessary GSX software to complete the pairing process. However, in 2018 Apple decided to start showing the customer the information that Apple devices had access to – the specific serial numbers of the components. If the serial number of a particular component is not recognized by the user's device, a message will appear informing the user that the part cannot be verified.

This parts pairing message first appeared in 2018 during screen replacements in the iPhone Xr, Xs and Xs Max series. Although Apple's GSX software was used to repair parts for models prior to 2018, the “unreal” message will not populate. screen. In other words, parts from older iPhones were interchangeable between the same model of Apple device without getting a bogus warning. A technician can use a new Apple iPhone 5c genuine OEM pull screen replacement to fix any other iPhone 5c cracked screen. When iPhone screens are changed, no message will populate.

In some cases, replacing a part using Apple's software and not pairing will cause an Apple device to lose some important functionality. For example, an iPhone user will be lost. Real accent Functionality on their Apple iPhone when the screen replacement is later completed *** Another example is when a front camera is replaced with another identical front camera of the same model, Face ID no longer works. will do This means that the iPhone will not unlock by scanning the user's face unless the user installs a front-facing camera purchased by Apple and paired through Apple's software. Why does this happen?

The infrared camera on the front-facing selfie camera of all iPhones with Face ID enabled is secretly paired with the front-facing camera's serial number and the user's device. In other words, unless you buy a camera directly from an Apple service provider, an iPhone user won't be able to retain the ability to unlock their device using their face, which is the entire phone's password. is one of the main features.

From the perspective of many OEMs, including Apple, it is important for them to maintain data on how often a device part is replaced. Such information is helpful in eliminating inferior parts suppliers and identifying failures in individual components of their products. Today's smart gadgets consist of components from hundreds, if not thousands of suppliers around the world. In a globalized economy, it is crucial for OEMs to have data on changes in individual components, or at least that is their argument.

It's important to note that not all OEMs have the same requirements or standards for how and when a device is paired. Some hardware manufacturers enable pairing by simply plugging in new components, some manufacturers want you to pair through their software but not change the user experience without pairing, and some manufacturers create pop-ups. proceeds to explain the immediate anomalies without coupling.

This problem has arisen mainly because with each new release of the Apple iPhone more and more parts require pairing to maintain their full functionality and designed purpose. Many opponents of the so-called “parts pairing scheme” might say, “What's the point of replacing your front camera if it's disabled on your iPhone when you're using a Grade A bridge-part Face ID?” ” A valid question, but proponents may say “how will consumers know if a part being installed themselves or especially in the case of service by a third party is actually a genuine OEM part?” . It is common knowledge that many repair shops across the country, some willingly and some unknowingly, falsely advertise cheap quality aftermarket parts as “Apple Genuine OEM Parts”. These are legitimate concerns on both sides, however it is important that as an industry we work together to address the concerns of both the consumer and the manufacturer, ultimately the consumer has the right to repair as one sees fit. , but consumers should never buy a product to begin with if the OEM's brand is tarnished by the widespread use of inferior components on their devices.

I won't pretend to be the world's best expert on electronics manufacturing, there are plenty of others who could hold that title today. That said, we know that serial numbers are often stored and authenticated using encryption. Common checksum algorithms including CRC32, MD5, or SHA-1. I don't think it would be a stretch to realize that it would be entirely possible to verify the status of a device's components in the device's settings without the need for external pairing software.

After all, like tools 3uTools Apple has enabled users to access information such as battery cycle counts or serial numbers for free over the past five years. Although Apple has chosen not to make most of its component information accessible to the user, this may change. Apple recently decided to display the cycle count of the batteries inside the iPhone, which is a big change in policy from previous years. In addition to the battery cycle count, serial numbers and component information for all parts inside the iPhone should be easily accessible to users directly in Settings.
