communicated with some buyers on Xianyu, which really opened my eyes. What surprised Digital Rice Bowl earlier was: "I'm a student, can you give me a mobile phone? I'll pay for the postage." He even said I paid for the postage myself, so you don't have to pay me two hundred. Is that all? Can't you mail it to me? seems to be my problem (disclaimer: most student users are very reasonable, and some do like to use their student identities to cause trouble). Now there is a time when Digital Rice Bowl does not understand Apple phones. Anyway, the understanding has been refresh.
Recently, a buyer came to me and took a fancy to a iPhone12 machine. The initial conversation went very smoothly, and then when the transaction was about to begin, he suddenly asked me: Can this machine be downgraded to iOS14 for me? Can I buy it if I can downgrade to iOS14? I told him that Apple's system can only be upgraded but not downgraded, especially if he is not good at cross-border versions and cannot be downgraded. I can find you an iPhone 12 with iOS 14. If he doesn't want to have this one, why not? Tell me, others can downgrade, but I can Baidu. Many tutorials are so simple that I don’t know how to do it. End the communication.
This really taught me a lesson. After that, I looked for various downgrading tutorials. There were quite a few online, but none of them were useful. Does anyone know how to downgrade from iOS15 to iOS14? Please share in the comment area, Another buyer also taught me a lesson. When communicating, he asked Digital Rice Bowl: Can the serial number of this Apple be changed? My first reaction was how is this possible?
The serial number is like a person's ID card and cannot be modified. The only one that can change the serial number is the official website . If some machines have after-sales problems, Apple will cancel or replace the serial number of your original mobile phone, that is Some black machines will show that the serial number has been changed. At that time, many unscrupulous merchants took advantage of the loopholes to make profits. There were generally many serial number changing machines on the market.
In the end, he told Digital Rice Bowl many "real cases" of modifying serial numbers. If you just throw out a sentence and you don't understand anything, you still write the official account, forget it! As an individual, I use technical means to modify the serial number. I really don’t know how to use digital rice bowl. I suddenly felt that Xianyu has become a master. My knowledge is getting narrower. I still need to learn more and communicate more when I have time.
