In this article, we will analyze all the current ways of updating, from standard OTA to manual firmware through Fastboot, and also explain how to avoid typical problems like hanging on the logo or data loss.
It’s important to understand that Xiaomi 13T (codename arene) supports both official updates through system settings and alternative methods for power users. If you’ve never encountered smartphone firmware, we recommend starting with an automatic method. For enthusiasts who want to install custom software or roll back on the previous version, we have prepared separate instructions tailored to the specifics of the model.
