What are you most afraid of when buying a used iPhone? It must be a refurbished machine, although the refurbished machine looks bright and beautiful, but in fact it is a patchwork of various high-imitation parts. Not only is the experience not good, but the life span is not long. But now many refurbished iPhone inspection reports are all green, so many people think it is the original machine, at present, at least dozens of people every day find me, saying that they bought a refurbished machine with a full green machine inspection report.
Today, take this iPhone XS Max as an example, this iPhone XS Max has replaced the shell, screen, battery, camera, changed the card slot, or the expansion machine, this is a serious refurbished machine. However, the machine inspection report is still all green, so many people think that this is a second-hand original machine with excellent color.

If you only look at the appearance, you will definitely not find anything. After all, the appearance is the easiest, just change the shell to do the same color, if you buy the iPhone signal, it is possible to change the shell.
Is there a original color that is the original machine? Not necessarily, because the original color can also be brushed. Therefore, based on this alone, it is impossible to judge whether the machine is an original screen.
This is the machine inspection report, you can see that the machine inspection report is all green, there seems to be no problem. Show this iPhone XS Max is silver, 256GB official replacement, BNP version, network model is A2104. Everything was working fine. Next we look at the native.
About the model in this machine shows that the beginning of N, is the official replacement machine, CH / A end, is the national bank machine, the memory is 256GB. All this is the same as the machine inspection report, indicating that this iPhone is the original machine? No problem? Wrong, the model can be changed, and the memory can be expanded. So far, we still can't tell if the machine is a refurbished machine.
Next, we have to use the serial number to query the whole machine report, because the serial number and the whole machine report can not be changed, so we only need to query the whole machine report, found that the data is not right, that means that this iPhone is a refurbished machine. Querying the whole machine report is also the most important step before buying a machine.

The network model is A1921, now it's A2104.
The place of purchase is displayed overseas (US version), and now it is bnsuckle.
Whether the official replacement shows [No], indicating that it is not an official replacement.
The US version is a physical single card, and the national line is a physical dual card, so the machine must have changed the card slot.
Without disassembling the machine, we found that the machine had so many problems, it was a refurbished machine. But if you only look at the machine inspection report, you can't find the problem at all, because the machine has changed the underlying data. If the iPhone changes the underlying data, whether it is a refurbished machine or a bomb machine, the inspection report is all green, so at this time, the inspection report has no reference value. Only when the whole machine report is queried and all the data is found to be consistent, the machine inspection report has the significance of reference. At present, there are many such iPhones, there have been many people recruited, if there are conditions, when buying, you must query the whole machine report, to avoid post-sale, rights protection difficulties and other issues.
