In this document, we are going to show you the process of Enabling Diag Mode on Xiaomi Qualcomm devices.

First of all, to enable the diag port, you need to:

  • Log into an existing MI account on the device
  • Insert a SIM card into the phone
  • In the developer options enable the "Install via USB" menu
  • Update the Chimera and Windows drivers

If these are done, you can connect the phone in ADB mode, then click on the "Diag Mode" procedure.

Once the procedure finishes successfully, the phone will be in Diag mode, you can check this in the Device Manager, where you will see that you have a new Diagnostics port (Qualcomm HS-USB Diagnostics 9091).
