Q1. Who should install OS2.0.208.0.VODCNXM on a Xiaomi 15S Pro?

This build is ideal for Chinese Xiaomi 15S Pro owners who want to fix HyperOS 2 bugs (like UI stutter, odd scroll behavior, or broken travel assistant and input‑method pop‑ups) or who need a clean, fully updated Android 15 base after experimenting with mods or root.

Q2. Does this update improve battery life and heat compared to earlier HyperOS 2 builds?

HyperOS 2.2 changelogs emphasize system optimizations, smoother animations and better scrolling, and general reports for 2.0.20x builds on other devices mention background optimizations that can reduce unnecessary wake‑ups. However, reviewers still note that the Xring O1 chip draws more power and runs hotter than some Snapdragon flagships under heavy gaming, so expectations for thermal miracles should remain realistic.

Q3. Is this ROM Android 16 or will it block my Android 16 / HyperOS 3 upgrade later?

No, OS2.0.208.0.VODCNXM is an Android 15 HyperOS 2 build; Xiaomi plans Android 16 for later HyperOS 2.3 or 3.0 releases on the 15‑series, including 15S Pro. Staying on an up‑to‑date 2.0.208.0 base keeps you within the supported branch and should not prevent future Android 16 OTAs when Xiaomi rolls them out for this model.

Q4. Will this China ROM include Google Play Store and Western apps after flashing?

No; as a CNXM build, it comes with Chinese services and app ecosystem and does not bundle Google apps or Play Store by default. You can still sideload GMS or use alternative stores, but that setup is manual and not officially guaranteed by Xiaomi.

Q5. Can a clean fastboot flash help with privacy‑related background traffic and unexplained drain?

Some Xiaomi 15‑series users report heavy background data and battery use by system apps, which they mitigate by revoking permissions and using firewalls. A clean flash to OS2.0.208.0 removes leftover junk and gives you a known‑good baseline, after which you can more systematically restrict unneeded apps and network access.

Q6. What if my Xiaomi 15S Pro is hard‑bricked and cannot enter fastboot mode?

The fastboot ROM here is only for devices that can still enter fastboot; deep‑brick recovery would require EDL or specialized service tools, which are generally restricted and best handled by professional repair centers. For most users, fastboot flashing with this package is the safest DIY method as long as fastboot remains accessible.

Xiaomi 15S Pro (dijun) HyperOS 2.0.208.0 China fastboot ROM download

The Xiaomi 15S Pro is a 2025 China‑only flagship built around Xiaomi’s in‑house Xring O1 chipset, a 6.73‑inch LTPO AMOLED display and a 6,100 mAh silicon‑carbon battery, positioned as a performance and battery‑life alternative to Snapdragon‑based flagships. Real users and reviewers consistently praise its raw power and stamina, but also report pain points such as heat and throttling in long gaming sessions, higher power consumption than Snapdragon rivals, occasional UI stutter, and background battery drain linked to HyperOS processes and data traffic.

The dijun-images-OS2.0.208.0.VODCNXM fastboot ROM is a full China HyperOS 2.2 (Android 15) system image that improves stability, refines animations and scrolling, updates security to mid‑2025, and fixes specific bugs like abnormal travel assistant and keyboard pop‑up behavior on the Xiaomi 15S Pro.

CRUCIAL WARNING: This fastboot ROM is strictly for the Xiaomi 15S Pro with codename dijun and China firmware (VODCNXM); do not flash it on Xiaomi 15, 15 Pro, 15 Ultra, Redmi, POCO or any other codename, or the phone can be permanently bricked.

Always match the region code (CNXM vs MIXM/EUXM, etc.) and Android version before flashing; cross‑region or downgraded installs can break network, OTA, or anti‑rollback rules, leaving the device unstable or unable to boot.

All official dijun-*.tgz fastboot packages overwrite core partitions and usually wipe user data; selecting “clean all and lock” on a mismatched system can relock the bootloader on an unsupported ROM and cause boot loops, account‑binding errors, or loss of recovery options.

Download Firmware for Xiaomi 15S Pro (dijun)

Because this is a single, relatively new HyperOS 2.2 build for the China Xiaomi 15S Pro, it should be the default choice when you need a full restore or clean reinstall; older OS2.0.20x builds are now mostly for downgrade testing or reproducing specific bugs. The package below is a fastboot ROM, which is more suitable than recovery/OTA ZIPs for deep repair, unbricking and wiping away long‑standing software issues.

Preparation Before Flashing

Click here for the Xiaomi 15S Pro (dijun) pre‑flash checklist

Confirm exact device and codename: In fastboot, run fastboot getvar product and make sure it returns dijun, and in Settings > About phone confirm that your build ends with VODCNXM (China) before using this ROM.
Backup your data: A fastboot flash will overwrite core partitions and usually erase apps, settings and internal storage data, so back up photos, chats, 2FA codes and documents to Xiaomi Cloud, Google, or a PC first.
Charge the phone: Aim for at least 50–60% battery; while 15S Pro charges quickly, a power loss mid‑flash can cause serious software damage or boot loops.
Unlock the bootloader: Use the official Mi Unlock tool on a Windows PC with your Xiaomi account; unlocking is required for fastboot ROMs and will itself wipe all user data.
Install drivers and extract ROM: Install Xiaomi USB drivers and Xiaomi Flash Tool, then fully extract the .tgz into a short folder path (for example C:\dijun_OS2.0.208.0) before starting the flash.
