File Selection Guide.

This section helps you choose the right Redmi K50 Ultra / Xiaomi 12T Pro firmware so you avoid flashing the wrong region or build.

• Match the codename: All official and custom packages here are for codename diting, which is used for Redmi K50 Ultra and Xiaomi 12T Pro in HyperOS and MIUI databases. Never flash diting firmware on a device with a different codename.
• Check HyperOS vs Android version: Builds starting with OS2.0. (for example OS2.0.210.0.VLFCNXM) are HyperOS 2 based on Android 15, while OS1.0.21.0.ULFJPXM is a HyperOS 1 build based on Android 14, confirmed by firmware trackers and the _15.0_ or _14.0_ segments in the filenames.
• Understand region suffixes: Xiaomi’s version codes use CNXM (China), MIXM (Global), EUXM (EEA/Europe), RUXM (Russia), TWXM (Taiwan), TRXM (Turkey) and JPXM (Japan), which appear at the end of each build number so you know which region a ROM targets.
• What each ROM is for: China OS2.0.210.0.VLFCNXM is ideal for users who want the very latest HyperOS 2 features, while Global, EEA, RU, TW and TR builds keep regional services and regulations, and the Japan OS1.0.21.0.ULFJPXM ROM is a HyperOS 1 option for Japanese units.
• Official vs Xiaomi.eu: The .tgz images files are official Xiaomi Fastboot ROMs; xiaomi.eu_DITING_OS2.0.210.0.VLFCNXM_15.zip is a Xiaomi.eu custom ROM based on the same China OS2.0.210.0 build, adding extra languages and modifications according to the Xiaomi.eu project description.
• Recoveries: The OrangeFox and TWRP builds for diting are third‑party custom recoveries that you can use to flash custom ROMs and make backups; they are not required if you only plan to flash official Fastboot ROMs with Mi Flash Tool.

⚠️Flashing Requirements

📱How to Flash the Firmware

Method 1: HyperOS Fastboot ROM with Mi Flash Tool

1. Download & extract the ROM: Download the correct Fastboot package for your region (for example, diting_images_OS2.0.210.0.VLFCNXM_20251107.0000.00_15.0_cn_4c43833361.tgz for China) and extract it to a folder on your PC.
2. Boot into Fastboot: Power off the phone, enter Fastboot mode, then connect it to your computer using the USB‑C cable.
3. Select the folder in Mi Flash: Open Mi Flash Tool, click “Select” and choose the extracted diting ROM folder, then confirm that your device appears in the list.
4. Flash HyperOS: Pick your preferred flashing option (clean flash is safest but erases data), click “Flash” and wait until Mi Flash completes the OS2.0.x or OS1.0.21.0 installation.
5. Reboot & set up: Let the phone reboot automatically, wait for the first HyperOS 2 or HyperOS 1 boot, and then go through the setup steps before restoring your backups.

Method 2: Fastboot Script (flash_all.bat) for Official ROMs

1. Extract the Fastboot package: Unpack the chosen .tgz ROM and find the flash_all.bat script inside the diting ROM folder.
2. Connect in Fastboot mode: Put your Redmi K50 Ultra / Xiaomi 12T Pro into Fastboot mode and connect it to your PC with the USB‑C cable.
3. Run the script: Double‑click flash_all.bat (or run it from a Command Prompt) to start flashing all the main partitions for your selected build, such as OS2.0.210.0.VLFCNXM.
4. Wait for success: Leave the phone connected until the script reports that flashing is complete and the device is ready to reboot.
5. Finish setup: Allow the first HyperOS boot to complete and then log in and restore your apps and data.

Frequently Asked Questions (FAQs)

How do you choose the right HyperOS 2 file for Redmi K50 Ultra / Xiaomi 12T Pro (diting)?

Go to Settings → About phone and check the current build suffix (for example MIXM, EUXM, CNXM), then pick the matching OS2.0.x Fastboot ROM for diting from the same region family so that system behavior and future OTA updates remain consistent.

Can the China OS2.0.210.0.VLFCNXM ROM be flashed on a Global Xiaomi 12T Pro (diting)?

The China OS2.0.210.0.VLFCNXM Fastboot ROM is tagged for CNXM devices, and there is no official guidance recommending cross‑region flashing, so using it on a Global MIXM unit is considered risky and mainly for very advanced users.

Does flashing OS2.0.210.0.VLFCNXM or OS2.0.205.0.VLFMIXM on diting fix battery drain and lag issues?

Official trackers confirm these builds as stable HyperOS 2 Android 15 releases, but they do not list specific performance or battery fixes, so you should treat a clean install as a general software refresh rather than a guaranteed cure for every issue.

Is Xiaomi.eu_DITING_OS2.0.210.0.VLFCNXM_15.zip an official Xiaomi firmware for Redmi K50 Ultra / Xiaomi 12T Pro?

No, Xiaomi.eu clearly describes its ROMs as community builds based on Xiaomi firmware, so this HyperOS 2 ROM for diting is a custom multi‑language ROM and not an official Xiaomi release.

Do you need an unlocked bootloader to flash these diting Fastboot ROMs?

Xiaomi’s bootloader policy and HyperOS flashing guides indicate that an unlocked bootloader is required to flash Fastboot images and custom recoveries on devices like Redmi K50 Ultra / Xiaomi 12T Pro.

Can OrangeFox-R11.3_1-Unofficial-diting.zip or twrp-3.7.1_12-v9.0_A15-diting-skkk.img be used on all HyperOS versions for diting?

The recovery threads state that these builds target Android 13–15 ROMs, but they do not guarantee support for every future HyperOS update, so you should always check the latest maintainer notes for compatibility before flashing on new builds.

Will installing a HyperOS 2 Fastboot ROM on Redmi K50 Ultra / Xiaomi 12T Pro (diting) erase my data?

Fastboot flashing with Mi Flash or flash_all.bat is usually documented as a clean install that wipes user data, so planning a full backup is essential before you flash any OS2.0.x or OS1.0.21.0 ROM on diting.
