Redmi Note 12S (sea) HyperOS 2 Fastboot ROM & TWRP Download (Android 15)
Redmi Note 12S combines a 6.43‑inch FHD+ AMOLED display, a 108MP main camera, a MediaTek Helio G96‑class platform (mt6781) and a 5000mAh battery, making it a popular mid‑range choice for photography and everyday gaming. With the move to HyperOS 2 based on Android 15, users commonly look for a clean way to upgrade from earlier MIUI 14 builds, fix bugs or recover from failed OTAs using official Fastboot ROMs and custom recovery tools.
This page is prepared after reviewing Redmi Note 12S HyperOS firmware trackers, official codename references for “sea”, and Xiaomi’s MIUI/HyperOS version code documentation, so the ROMs listed below match Redmi Note 12S (sea) only.
File Selection Guide.
Each HyperOS build number reveals the Android version, device code and target region; picking the wrong region or device code is a common cause of flashing errors and broken OTAs.
- Device and codename: Firmware trackers and HyperOS download pages identify Redmi Note 12S with codename sea, and the Fastboot ROM table lists OS2.0.207.0/VHZMIXM, VHZRUXM, VHZEUXM, VHZTWXM, VHZTRXM specifically for this device.
- Region suffix: In Xiaomi’s ROM naming scheme,
MI= Global,EU= EEA/Europe,RU= Russia,TR= Turkey,TW= Taiwan;XMidentifies Xiaomi’s own ROM brand. - Android version code: HyperOS versions such as
OS2.0.207.0.VHZMIXMare tagged with Android15.0in firmware tables, matching the_15.0_suffix inside each Fastboot filename. - Fastboot vs. Recovery: XM Firmware Updater lists both Recovery and Fastboot types; the
sea_*_global_images_....tgzpackages shown here correspond to the Fastboot entries (PC flashing). - TWRP package: The
twrp3.7_sea.zipfile is a custom recovery package for the same sea platform and is typically flashed after stock HyperOS is installed, for advanced backup and ROM management. (No official Xiaomi documentation exists for this TWRP; only the filename and codename match can be relied on.)

Flashing Requirements
Flashing a HyperOS Fastboot ROM normally wipes user data, so backing up photos, chats, accounts and documents to cloud or external storage is essential before starting.
A Windows computer, a good USB Type‑C cable and proper Xiaomi/MediaTek drivers are needed for Fastboot mode detection and Mi Flash Tool operation on Redmi Note 12S.
An unlocked bootloader is usually required for Fastboot flashing, and Xiaomi’s official bootloader unlock guide explains the waiting period and account rules that apply.
A battery charge of at least 50% and a stable USB connection reduce the risk of interruptions that might cause system corruption or a non‑booting device.
📱How to Flash the Firmware
Method 1: HyperOS Fastboot ROM via Mi Flash Tool
- Download and extract: Save the matching Fastboot ROM for Redmi Note 12S, for example
sea_global_images_OS2.0.207.0.VHZMIXM_20251031.0000.00_15.0_global_c73b48b0b4.tgz, and extract it to a folder on the PC. - Enter Fastboot mode: Power off the phone, then boot into Fastboot mode and connect it to the PC with a reliable USB cable.
- Load ROM in Mi Flash: Open Mi Flash Tool, select the extracted
seaROM folder (containingimagesand scripts) and confirm that the device is detected. - Start flashing: Choose the desired flash option (clean flash usually wipes data), click “Flash” and wait for Mi Flash Tool to complete the HyperOS installation.
- Reboot: Allow the phone to reboot automatically and wait patiently; first HyperOS 2 Android 15 boot on Redmi Note 12S can take several minutes after a full reinstall.

Method 2: Fastboot Script (flash_all.bat style)
- Unpack the ROM: Extract the
.tgzHyperOS ROM and locate script files such asflash_all.batinside the Redmi Note 12SseaROM directory. - Prepare the phone: Boot into Fastboot mode and connect the device to the computer, ensuring drivers are installed and Fastboot detects the phone.
- Run the script: Execute the appropriate script to flash the full OS2.0.x.x.VHZ* build; many scripts perform a complete wipe, so backups must be done first.
- Wait for completion: Keep the cable connected and wait until the script window indicates that flashing is finished and the device is ready to reboot.
- Reboot into HyperOS: Allow the phone to restart, then complete the HyperOS setup wizard once Redmi Note 12S boots on Android 15 for the first time.

Frequently Asked Questions (FAQs)
Which HyperOS Fastboot ROM should be used for Redmi Note 12S (sea)?
The safest choice is the ROM whose suffix (MIXM, EUXM, RUXM, TWXM, TRXM) matches the suffix shown in the current HyperOS or MIUI build on Redmi Note 12S in About phone.
Is OS2.0.207.0.VHZMIXM confirmed as Redmi Note 12S Global HyperOS 2 (Android 15)?
HyperOS trackers list “Redmi Note 12S Global – OS2.0.207.0.VHZMIXM – Android 15.0 – Fastboot” and match it with codename sea, confirming that this build is for Redmi Note 12S.
Can these Redmi Note 12S HyperOS Fastboot ROMs fix bootloops or failed OTA updates?
When a bootloop or stuck update is caused by software corruption, flashing the correct sea HyperOS Fastboot ROM is a common recovery method, provided Fastboot mode is still accessible and the bootloader is unlocked.
Does flashing OS2.0.207.0.VHZMIXM improve performance compared to MIUI 14?
Public firmware trackers focus on version, branch, Android level and file size rather than detailed performance claims; any performance change after moving from MIUI 14 to HyperOS 2 is due to the new system base, not a specifically documented “speed fix” in the Fastboot package itself.
Is TWRP 3.7 for sea officially supported by Xiaomi?
The twrp3.7_sea.zip file referenced here is not documented on official Xiaomi pages; its “sea” targeting is derived from the filename/codename only, so it should be treated as a community/custom recovery, not an official Xiaomi tool.
Can TWRP 3.7 be used on Redmi Note 12S HyperOS 2 without issues?
No official guarantee exists; compatibility depends on how the recovery was built for the sea platform, and only the codename matching suggests it is intended for Redmi Note 12S, so caution and up‑to‑date community feedback are important before use.
Does HyperOS 2 Fastboot flashing on Redmi Note 12S always wipe user data?
Many Xiaomi Fastboot methods and flash_all.bat scripts perform a full wipe, and guides for Mi Flash Tool and script flashing clearly warn that data is typically erased during the process.
