Official Xiaomi 15S Pro (dijun) HyperOS 2.0.208.0 China Fastboot ROM
The Xiaomi 15S Pro is a premium flagship smartphone featuring a 6.73‑inch 2K‑class LTPO AMOLED display at 120 Hz, Xiaomi’s in‑house XRing O1 3 nm chipset, up to 16 GB LPDDR5T RAM, and fast UFS 4.x storage for top‑tier speed and responsiveness. It also packs a large 6,100 mAh battery with high‑power wired and fast wireless charging plus a Leica‑tuned camera system, making it attractive to power users, photographers, and gamers. At the same time, owners often report heavy heating during camera or gaming use, faster battery drain than expected, and occasional UI micro‑stutters and app glitches that are largely software‑related rather than hardware faults.
The official China HyperOS 2.0.208.0.VODCNXM Android 15 fastboot ROM for codename dijun targets these issues with updated animations, camera and HDR tuning, GPS improvements, bug fixes, and newer security patches to deliver a smoother, more efficient system on the Xiaomi 15S Pro.

Flashing Requirements
- Backup your data: Fastboot flashing almost always wipes apps, accounts, and internal storage, so back up photos, chats, and documents to a PC or cloud before you start.
- Charge the phone: Ensure your Xiaomi 15S Pro battery is at least 50–60 % to avoid shutdown during the flash process.
- Windows PC & drivers: Use a stable Windows computer, install Xiaomi/Qualcomm‑class USB drivers, and connect via a good USB‑C cable for reliable transfer.
- Confirm codename & region: In Settings → About phone or using fastboot getvar product, verify that the device is Xiaomi 15S Pro with codename dijun on the China branch (VODCNXM) before flashing this ROM.
- Unlock the bootloader (for fastboot): Manual fastboot or Mi Flash installs require an officially unlocked bootloader; if your bootloader is locked, update using official OTA/Recovery packages instead.
How to Flash the Firmware
Method 1: Xiaomi Mi Flash Tool (Fastboot ROM)
- Prepare tools & ROM: On your Windows PC, install Xiaomi USB drivers and Xiaomi Mi Flash Tool, then download and extract dijun-images-OS2.0.208.0.VODCNXM… so the folder contains all fastboot image files.
- Load firmware into Mi Flash: Open Mi Flash, click the option to select firmware, and point it to the extracted dijun-images-OS2.0.208.0.VODCNXM directory so all partitions are mapped automatically.
- Enter fastboot mode: Power off the Xiaomi 15S Pro, then hold Volume‑Down + Power to enter fastboot mode and connect the phone to the PC with your USB‑C cable.
- Start flashing: Confirm that Mi Flash detects your device, choose a safe option such as “clean all”, then start the flash and wait patiently until a success message appears without disconnecting the cable.
- First boot: Reboot the phone; the first start on HyperOS 2.0.208.0 may take several minutes while the system optimizes apps and services.

Method 2: Fastboot Script (flash_all.bat)
- Install platform tools: Set up Android platform‑tools on your PC, then extract the fastboot ROM so that flash_all.bat (or similar scripts) and the image files reside in the same folder.
- Connect in fastboot: Boot the Xiaomi 15S Pro into fastboot mode, connect it via USB, and verify detection with a quick fastboot devices command.
- Run the script: Execute flash_all.bat to automatically flash all key partitions; avoid unplugging the cable or closing the window until the script completes.
- Wait for reboot: After flashing, the phone should reboot into HyperOS; if it does not, long‑press the Power button once to trigger a manual restart and wait for the system to load fully.
- Restore & test: Complete setup, restore your backups, then monitor heat, battery life, camera stability, and overall smoothness for a few days to confirm previous issues are resolved or reduced.

Frequently Asked Questions (FAQs)
What Xiaomi 15S Pro problems can OS2.0.208.0.VODCNXM help fix?
This official HyperOS 2.0.208.0 China build can resolve many software‑side issues such as random freezes, UI animation glitches, occasional black screens with older apps, and some bootloops after failed OTA updates by reinstalling a clean, optimized system. It also improves camera Pro mode behavior, HDR video handling, and GPS reliability in complex environments, which helps reduce crashes and inconsistent imaging performance.
Does this update improve heating and battery drain?
Heating and faster battery drain during camera use, social apps, or gaming are common complaints on the Xiaomi 15 and 15S family, especially on early HyperOS 2 builds. OS2.0.208.0.VODCNXM refines animations and system behavior and is part of Xiaomi’s ongoing HyperOS 2.2 tuning, which aims to smooth workload distribution and reduce unnecessary background usage, helping thermals and endurance when combined with sensible settings.
How do I know if this firmware is compatible with my phone?
You must confirm that your device is the Xiaomi 15S Pro China variant, that its codename is dijun, and that it is on the China VODCNXM firmware branch before flashing this ROM. Global or other regional Xiaomi 15‑series models require their own specific builds, and flashing this China firmware on the wrong device can cause serious network, camera, or boot issues.
Can this ROM unbrick a soft‑bricked Xiaomi 15S Pro?
If the phone still enters fastboot mode and the bootloader is unlocked, flashing the correct dijun fastboot ROM can often recover from soft bricks such as bootloops, stuck HyperOS logo, or crashes after a bad update. Devices that cannot reach fastboot or show no signs of life usually need professional repair or EDL‑level tools rather than user‑level flashing alone.
Is OS2.0.208.0 a big upgrade over earlier HyperOS 2 builds?
Compared with early HyperOS 2 releases for the Xiaomi 15S Pro, OS2.0.208.0.VODCNXM includes newer Android 15 security patches, refined animations, better camera and HDR tuning, and targeted bug fixes collected during Mi Pilot testing. For long‑term stability, security, and camera performance, updating to this stable build is advisable as long as you follow safe flashing procedures and back up your data.
