After replacing 128G flash, the possibility of white apple?

There is a key step in the process of replacing a 128G flash chip. It is to write system information. Since the iPhone's SN code is located in its flash memory, the iPhone's system will verify whether the machine's SN code matches the IMEI code. If not, Matching can not boot.

Surely someone will ask you, although your SN code matches the IMEI code, but your SN code's corresponding capacity version has been inconsistent. Apple can validate your capacity information and make your iPhone inoperable. This is indeed the case. Son, it is precisely because Apple did not join the verification of the capacity version when it activated the mobile phone, so we can take advantage of it. If we say that Apple wants to plug this loophole, it must increase the “verification capacity when activated”. The function, replaced by the programmer's assertion, is that it must add a few lines of functional code to the system so that we can verify the capacity together when the network is activated. With regard to this, things are very clear. As of the current beta iOS 9.2, the replacement of 128G Flash iPhone can still be activated normally. Even if Apple adds capacity verification in the official version of iOS 9.2, as long as we do not update the system, Apple took us to no avail, and at present we can even brush back more secure iOS 9.1. So at present, as long as the replacement of 128G flash memory does not upgrade the system, the probability of a white apple is 0%.

You dare to jailbreak, afraid to change 128G flash memory?

Apple’s attitude to jailbreaks has always been an objection. They allege that the jailbreak iPhone is illegal, which infringes Apple’s system’s copyright and clearly states that the iOS system prohibits users from making jailbreak changes and that Apple will not provide warranty for jailbroken iPhones. , And Apple closed the loopholes in every iOS update.

Jailbreaking is essentially exploiting iOS system vulnerabilities to crack the entire iOS system and making it more open. Although we did not replace hardware in the process of jailbreaking, we have actually made a lot of changes to the internal file information of the system. For this reason, The jailbreak machine is unable to upgrade the system through OTA, because after modifying a lot of system internal file information, the iPhone cannot pass the authentication of the apple server at all, will cause white apple finally.

So why did the jailbroken iPhone upgrade the system through the DFU mode? DFU mode is Apple's official left behind for a special iPhone, its role is in the iPhone black screen, can not boot, and so on under special circumstances so that users can force upgrade the system to solve the problem of the iPhone can not use, as long as you have iOS firmware, It can be through the itune iOS firmware into the DFU mode of the iPhone, although the jailbreak to modify the system internal files, but after the brush machine system has become a state without jailbreak, activation can be verified by Apple, so the jailbreak user has been Both can be upgraded normally with the DFU mode.

The jailbreak modifies the system information, while the 128G upgrade is to modify the system information + hardware information, so even if we successfully brush to the latest iOS system in the DFU mode, the activation verification step, as long as the new version of the iOS system has added verification capacity We can't activate it, but still, as long as we don't upgrade the system, Apple can't take us.

Note: Apple will only start the server verification after the machine has been brushed/unactivated. As long as your machine has been activated and verified, Apple will not verify your iPhone again if it is not flashing.

Do you dare to buy a monster machine and dare not rise 128G?

The devil machine is brushing machine

Friends who understand the iPhone parallel market should have heard the word "fairy machine". The so-called demon machine is to modify the hardware serial number, base band, IC information and other hardware information so that the original lock machine / US version machine / Japanese version machine Some of the iPhones posing as Hong Kong editions/licensed to obtain high profits, some of which have also replaced the motherboards, even if a samurai machine that has replaced the motherboard has modified the information by jailbreaking, it can even bypass Apple's server after the flashing machine to verify it. Use in the case of activation, because as long as bypassing the verification step, as long as the follow-up does not brush machine / upgrade system, Apple will not perform server verification again, so the devil machine can deceive many consumers. In contrast, 128G flash memory is a matter of fact, and the demon machine is a bit like, both are to modify the system information, replace the hardware parts, the difference is that the operation of the devil machine is more difficult, basically must bypass the apple's verification, otherwise it can not use.
