How to save the contents of the mobile phone after the motherboard is broken?

Nowadays, the smart phone is highly integrated, and the processor and flash memory chip on the motherboard are welded together, so the function of a module on the motherboard is broken, and the whole board may need to be replaced. Theoretically, as long as the flash memory chip is not damaged, it should be able to read data by taking the chip out of the motherboard with a hot air gun and installing it on other mobile phones.

But only for early Android phones. Apple phones and newer Android phones are encrypted, and the contents of flash memory chips cannot be obtained unless they are read by the corresponding CPU. At the beginning of 20 16, the famous FBI was unable to read a suspect's iPhone due to technical restrictions.

5c mobile phone, and fought with Apple for a long time.

As for Xiaomi 5S released on 20 16, will it have strong encryption like Apple's mobile phone? As the author is not a maintainer, I can't give you a definite answer. If there is no solution after Xiaomi is officially sold, you can also take your mobile phone to a more professional third-party maintenance point to ask if you can keep the data.

Considering that even if the data is not encrypted, reading data from a separate flash memory still requires high technology, so even if the data can be recovered, it will definitely require a lot of maintenance costs. Because data is priceless. In fact, the flash memory chips of most smart phones have a certain life, and the common eMMC flash memory will fail to some extent if it is completely erased 1000 times. Fortunately, the amount of data written by smart phones is relatively small, and 1000 erasure is enough for several years. Therefore, under normal circumstances, it is difficult for the flash memory of mobile phones to have problems.

In order to avoid the situation that the data can't be read because other components on the motherboard are damaged, we should pay attention to turning on the "cloud service" function of the system when using the mobile phone. Now Xiaomi, Huawei and other brands of mobile phones support cloud backup, and key photos, address books, text messages and documents in mobile phones can be backed up to the cloud server of mobile phone manufacturers. In this way, even if the mobile phone is damaged or lost, important data can be retrieved through the cloud service account.

Even if you don't want to use the cloud service function of your mobile phone, you should develop a good habit of backing up market data. Export the important photos and documents in the mobile phone to the storage media that are not easy to be damaged, such as computers and mobile hard disks, so as to avoid regretting the loss of important data.
