⚠️ Flashing Risks & Disclaimer
This NFC variant uses the Snapdragon 685 with modern partitioning and verified boot, so flashing a non‑topaz ROM or altering critical partitions such as super, boot, or vbmeta with incompatible images can lead to non‑booting firmware that may require Qualcomm EDL‑mode recovery. Because HyperOS fastboot ROMs for this phone rewrite multiple partitions at once, any interruption, wrong region selection, or manual script editing can result in bootloops, loss of NFC features, or radio issues until a correct build is reflashed.
Bootloader unlocking and installing TWRP or Xiaomi.eu can wipe user data, affect Widevine level, and disable standard OTA flows for some branches. Flashing is done entirely at the user’s risk, so a complete backup of photos, app data, and important files is strongly advised before changing firmware.

Flashing Requirements
This NFC variant uses dedicated HyperOS 2 fastboot ROMs, so a PC‑based fastboot workflow is required for full reinstalls or region changes when OTA or local update cannot recover the phone. A Windows PC, up‑to‑date Qualcomm and Xiaomi USB drivers, and Xiaomi Mi Flash Tool (or an equivalent fastboot setup) are needed for TGZ packages, while TWRP is used when flashing the Xiaomi.eu ZIP or taking advanced backups.
- Verify that the device codename is topaz (shown by
fastboot getvar productin fastboot mode or in device info) and that the region suffix (VMGMIXM, VMGEUXM, VMGRUXM, VMGIDXM) matches the intended firmware. - Ensure the bootloader is officially unlocked before attempting fastboot flashing or booting TWRP, as locked devices are generally restricted to official OTA updates.
- Back up all important data from internal storage, because recommended flashing modes (especially clean all or switching between stock HyperOS and Xiaomi.eu) will usually wipe user data.
- Charge the battery to at least 50% and use a reliable USB‑C cable directly connected to the PC to reduce the risk of disconnections during the flash.
How to Flash the Firmware
The steps below summarize a typical process for flashing a topaz HyperOS fastboot ROM with Mi Flash; Xiaomi.eu and other custom builds are usually installed through TWRP on this device.
- Download the correct topaz fastboot TGZ for the device’s region (for example, OS2.0.202.0 VMGMIXM for Global) and extract it on your PC until the folder containing the images and fastboot scripts is visible.
- Install Qualcomm and Xiaomi USB drivers, then set up the Xiaomi Mi Flash Tool and load the extracted ROM folder, confirming that the tool recognizes the path and lists the images without errors.
- With OEM unlocking enabled (if possible), power off the phone, boot into fastboot mode by holding Volume Down + Power, and connect it to the PC so it appears as a fastboot device in Mi Flash.
- In Mi Flash, select a suitable flashing mode (clean all is recommended for major updates or region changes), verify that the correct device is listed, then start the flash and avoid interrupting the process until a success message appears.
- After flashing completes, the device should reboot into HyperOS 2; first boot on Android 15 can take several minutes while the system optimizes apps and rebuilds caches, so allow extra time before troubleshooting.

Frequently Asked Questions (FAQs)
Is this firmware only for the NFC version of Redmi Note 12 4G?
These HyperOS 2 builds target the topaz codename, which corresponds to the Redmi Note 12 4G NFC variant; non‑NFC units usually use the tapas codename and different packages, so mixing them is not recommended.
Can a Global VMGMIXM ROM be flashed on a phone that originally shipped with VMGEUXM or VMGRUXM?
Cross‑flashing between Global, EEA, Russia, and Indonesia branches is technically possible on matching topaz hardware using a clean fastboot flash, but it can change region‑specific features and affect future OTA availability.
Does the Xiaomi.eu TOPAZ HyperOS 2 ROM include NFC support?
The Xiaomi.eu_TOPAZ_OS2.0.202.0.VMGMIXM_15.zip is based on the Global HyperOS 2 VMGMIXM firmware for topaz and keeps core hardware features, including NFC, while adding multi‑language and EU‑style customization.
Is a custom recovery like TWRP required to install the official HyperOS TGZ ROMs?
No, official HyperOS fastboot ROMs are designed for Mi Flash or fastboot scripts and do not require TWRP; TWRP is mainly used for Xiaomi.eu, other custom ROMs, or advanced backup and restore operations.
Will flashing these ROMs wipe internal storage on the Redmi Note 12 4G NFC?
Most recommended flashing modes for topaz, especially when using clean all or switching from stock HyperOS to Xiaomi.eu, erase userdata, so internal storage should be treated as expendable unless backed up.
Can Xiaomi.eu ROMs for topaz also be used on tapas devices?
Some Xiaomi.eu releases have added combined support for both topaz and tapas, but users must confirm explicit compatibility notes for each build; official HyperOS TGZ ROMs remain strictly separated by codename.
How can the correct region and codename be checked before flashing?
In fastboot mode, fastboot getvar product should report topaz, and within the existing system the full build string (such as OS2.0.202.0.VMGMIXM) appears under the firmware version in settings, indicating region and branch.
Can these HyperOS 2 fastboot ROMs fix performance issues on Snapdragon 685?
A clean flash of the correct HyperOS 2 build can help resolve software‑related slowdowns or update bugs, but it cannot change hardware constraints like RAM or CPU/GPU capability on the Snapdragon 685 platform.
