Interrupting the process or using unofficial sources can lead to unstable work, so it is important to follow the proven algorithms of actions described below.
What is an OTA Update and How Does It Work for Xiaomi?
OTA (Over-The-Air) is a method of remote software distribution. Unlike manual installation through a computer, where the user downloads the archive and downloads it to memory, the entire process is controlled by the manufacturer's servers. The smartphone periodically asks the server for a new build that is suitable for your model and region.
There are two main types of packages that the system can offer: One is an incremental update that weighs a little and contains only modified files; the second is a complete package that includes the entire operating system anew; and to solve problems with bugs or bugs, it is always better to choose the full package, since it overwrites system files clean.
