In fact, many people think that the 128G expansion of the iPhone is dangerous, mainly because we have modified the hardware of the iPhone and also modified the hardware information inside the system. Everyone is worried that Apple will prevent this from happening through some verification methods. They are afraid that the 128G iPhone will become a "white apple", but have you ever thought about it, In fact, 128G promotion is very similar to prison break.
How did the iPhone rise to 128G?
Front of iPhone 6 Plus original flash memory chip
back
Disassemble iPhone to expose the motherboard
Find the flash memory chip on the iPhone motherboard and remove it
Write system information of iPhone into 128G flash memory chip through computer
Solder the 128G flash memory chip to the iPhone motherboard
Put iPhone into DFU mode, connect to iTunes for upgrade
Is it possible for White Apple to replace 128G flash memory?
A key step in the process of replacing the 128G flash memory chip is to write system information. Since the SN code of the iPhone is located in its flash memory, the iPhone system will verify whether the SN code of the machine matches the IMEI code. If not, the machine cannot be powered on.
At this point, someone must ask, although your SN code matches the IMEI code, the capacity version corresponding to your SN code has been inconsistent. Apple can make your iPhone unable to activate and use by verifying the capacity information. This is indeed the case. It is because Apple has not added capacity version verification when activating the phone, so we have an opportunity to take advantage of it, If Apple wants to close this loophole, it must add the function of "verifying capacity during activation". To be a programmer, it must add a few more lines of functional code in the system so that we can verify the capacity together during online activation. Speaking of this, it is clear that as of the current beta version of iOS 9.2, the iPhone with 128G flash memory can still be activated and used normally. Even though Apple has added capacity verification in the official version of iOS 9.2, as long as we do not update the system, Apple will have no way to take us. At present, we can even brush back the more secure iOS 9.1. So for now, as long as the 128G flash memory is replaced and the system is not upgraded, the possibility of White Apple is 0%.
You dare to break out of prison and change 128G flash memory?
Apple has always been opposed to jailbreaking. They said that jailbreaking iPhone is illegal, which infringes the copyright of Apple system. They clearly pointed out that iOS system prohibits users from making jailbreaking modifications, Apple will not provide warranty for jailbreaking iPhone, and Apple will block the jailbreaking loopholes in every iOS update.
Prison break is essentially to crack the entire iOS system by using iOS system vulnerabilities to make it more open. Although we did not change the hardware in the process of prison break, we actually have made a lot of changes to the internal file information of the system. Because of this, the jailbroken machine cannot upgrade the system through OTA, Because the iPhone that has modified a lot of internal file information of the system cannot pass the verification of the Apple server at all, it will eventually lead to a white apple.
So why can jailbroken iPhones be upgraded through DFU mode? DFU mode is an official way left by Apple for special iPhones. Its role is to enable users to forcibly upgrade the system to solve the problem that iPhones cannot be used normally under special circumstances such as the iPhone's black screen and inability to boot. As long as you have iOS firmware, you can use iTunes to brush iOS firmware into the iPhone in DFU mode. Although prison break has modified the internal files of the system, However, after the reboot, the system has turned into an unbreakable state, which can be verified by Apple when activated, so jailbroken users can always upgrade normally through DFU mode.
The jailbreak modifies the system information, while the 128G upgrade modifies the system information+hardware information. So even if we successfully swipe the latest iOS system in the DFU mode, when the activation verification step is reached, as long as the new version of the iOS system has added the verification capacity, we cannot activate it. However, as long as we do not upgrade the system, Apple will have no way to deal with us.
remarks: Apple will only start server verification on an iPhone that has not been activated after it is flushed. As long as your iPhone has been activated for verification, Apple will not verify your iPhone again without flushing.
You dare to buy a demon machine, dare not upgrade to 128G?
Demon machine is cleaning
Anyone who knows about the iPhone parallel market should have heard of the word "demon machine". The so-called demon machine is to modify the hardware serial number, baseband, IC information and other hardware information make the original iPhone with lock machine/American machine/Japanese machine fake Hong Kong version/shipment to obtain high profits, and some of them have also replaced the motherboard. Even a demon machine that has replaced the motherboard can even bypass Apple's server verification after the machine is flushed after it changes information through prison break, and can be used without activation, because as long as the verification steps are bypassed, In the future, as long as the machine is not cleaned/the system is upgraded, Apple will not perform server verification again, so the demon machine can fool many consumers. On the other hand, the replacement of 128G flash memory is actually similar to the demon machine. Both of them modify the system information and replace hardware parts. The difference is that the demon machine is more difficult to operate and basically needs to bypass Apple's verification, otherwise it cannot be used.
I'm brave enough to upgrade to 128G, but what's wrong?
It's hard to say so much Daosheng 128G flash memory Is there no risk at all? What I said above is not to tell you that there is no risk when you upgrade 128G, but that you don't need to worry about the problem of white apple when you upgrade 128G, and the remaining risk is left to the old mechanic.
Residual risk:
Whether to replace the new 128G flash memory
How about the technology of welding 128G flash memory?
100% warranty lost after 128G
There is a saying that you need to change it sooner or later. The 128G upgrade is your choice, and there is nothing to say about losing the official warranty. In addition, at present, only the older generation iPhone, including 6/6 Plus, can replace the 128G. The latest 6s/6s Plus cannot be replaced. As an old iPhone, it is estimated that there is not much warranty time left, and it is nothing to lose the 2-3 month warranty, The key to upgrading 128G is whether the maintenance organization replacing 128G flash memory has excellent technology and can provide 128G flash memory chips with guaranteed quality.
Conclusion:
So if you are still a 16G user/a user who thinks the capacity is not enough, and you are willing to sacrifice the warranty to upgrade 128G flash memory, and can find a reliable maintenance agency, then don't hesitate to be a teenager! Quickly upgrade to 128G. After Apple adds new system verification, you can't upgrade if you want. But if you don't have confidence in the technology of the maintenance organization, feel that the capacity is really enough, or don't want to lose the iPhone warranty service, you also have only one choice, which is never to upgrade to 128G.
