Download Xiaomi 15S Pro (dijun) Firmware (HyperOS 2.0)

[Daniel]

The Xiaomi 15S Pro (codename "dijun") is the first smartphone powered by Xiaomi's in-house XRING O1 chipset. This 10-core, 3nm processor aims to rival the best flagship chips. The device ships with HyperOS 2.0 based on Android 15. Due to its unique chipset architecture, flashing the correct firmware is critical to avoid hard-bricking the device.

How to Flash the Firmware​

These firmware files are flashed using the Mi Flash Tool. This will erase all your data.

Method 1: Flashing Fastboot ROM (.tgz)​

1. Step 1: Download the

   .tgz

   firmware file and extract it to a simple folder on your PC (e.g.,

   C:\dijun_rom

   ). Do not use a folder path with spaces.
2. Step 2: Download, extract, and run MiFlash.exe as an administrator.
3. Step 3: Power off your phone completely. Boot into Fastboot Mode by pressing and holding the Power + Volume Down buttons until the fastboot logo appears.
4. Step 4: Connect your phone to the PC via USB. Click the "Refresh" button in Mi Flash Tool to detect the device.
5. Step 5: Click "Select" and navigate to the extracted firmware folder (the folder containing the

   images

   folder).
6. Step 6 (CRITICAL): At the bottom of the tool, select "Clean all".
   
   • WARNING: Do NOT select "Clean all and lock". Locking the bootloader if any system partition has been modified or if flashing a future non-original ROM could be catastrophic.
7. Step 7: Click "Flash" to begin. The process may take longer than usual due to the large system image.
