How to Flash the Firmware (Quick Steps)
Method 1: Flash official Fastboot ROM (.TGZ) using Mi Flash Tool
- Download the correct topaz ROM for your region (example: topaz_global_images_OS2.0.202.0.VMGMIXM...tgz for Global).
- Extract the.tgz until you get the ROM folder contents (images/flash scripts).
- Boot your Redmi Note 12 4G NFC (topaz) into Fastboot mode (Power + Volume Down).
- Open Mi Flash Tool, select the extracted ROM folder, refresh devices, then start flashing.
- Reboot and allow extra time for first boot.
Method 2: Flash Xiaomi.eu ZIP in TWRP (Custom ROM)
- Backup your data and make sure you understand bootloader/recovery requirements.
- Boot into TWRP and confirm it can read your storage.
- Copy xiaomi.eu_TOPAZ_OS2.0.202.0.VMGMIXM_15.zip to the phone (or sideload if that’s your workflow).
- Flash the ZIP in recovery (wipe/format steps depend on your current ROM state and encryption).
- Reboot system and allow extra time for the first boot.
Method 3: Test-boot TWRP via Fastboot (Safer First Step)
- Boot the phone into Fastboot mode.
- On your PC, run: fastboot boot twrp-3.7.1_12-0-topaz-TeamWin.img
- If recovery boots correctly, proceed with backups and ZIP flashing as needed.
- Avoid permanently flashing recovery unless you fully understand your device’s partition layout.
- Reboot normally when finished.
