What does MDL1 code mean in Xiaomi models?

The MDL1 marking is the internal designation of the hardware platform that Xiaomi assigns to TVs based on the AMLogic T972 chipset, which is a mid-range processor used in models released in 2020-2022. It is important to understand that MDL1 is not the name of a particular model, but a general index for a whole group of devices.

Why does this matter? The fact is that firmware, drivers, and even some accessories (such as remotes or mounts) can only be compatible with a particular platform. If you download firmware for MDZ-22-AA (another platform) and try to install it on MDL1, the TV may stop turning on or lose some of the features.

The MDL1 code is usually found in the following places:

• 📄 In the service menu of the TV (called by a combination of buttons on the remote control).
• 💾 In the name of firmware files on official and unofficial resources (for example, mdl1_global_2.1.0_stable.zip).
• 🔧 On the back of the TV (near the serial number).
• 🛠️ In the system logs when connecting to ADB.
