The firmware files on this page are official HyperOS 2 (Android 14) Fastboot ROMs for the Redmi Note 12 Pro 5G / Pro+ 5G / Discovery 5G family with codename ruby, released across multiple regions (China, Global, India, EEA, Russia, Indonesia, Taiwan, Turkey, and South Korea).
Online user feedback around the Redmi Note 12 Pro series after HyperOS updates often mentions battery drain and overheating (sometimes even during light usage), and some users look to a clean flash of the correct regional Fastboot ROM as a “fresh start” when OTA updates seem to worsen performance.
Each ROM below targets a specific region branch, so it’s safest to install the package that matches the suffix in your current build (for example, UMOMIXM for Global or UMOEUXM for EEA).
For a full step-by-step walkthrough (with pictures/videos) on flashing Xiaomi Fastboot ROMs using Mi Flash Tool, refer to this complete guide:

Online user feedback around the Redmi Note 12 Pro series after HyperOS updates often mentions battery drain and overheating (sometimes even during light usage), and some users look to a clean flash of the correct regional Fastboot ROM as a “fresh start” when OTA updates seem to worsen performance.
Firmware flashing warning (ruby)
- Flash only firmware built for codename ruby (Redmi Note 12 Pro/Pro+/Discovery 5G); flashing the wrong codename can permanently brick the device.
- Match your current region suffix (CNXM / MIXM / INXM / EUXM / RUXM / IDXM / TWXM / TRXM / KRXM) with the same suffix in the ROM you download to avoid update/feature conflicts.
- Fastboot flashing typically wipes user data; back up photos, files, and app data first.
- These are Fastboot packages (.tgz) intended for Xiaomi Mi Flash Tool workflows and usually require an unlocked bootloader.

The Requirements
- A Redmi Note 12 Pro 5G / Pro+ 5G / Discovery 5G confirmed as codename ruby.
- Unlocked bootloader (Fastboot flashing and region restores commonly require it).
- Windows PC + USB cable + stable USB port (avoid disconnects during flashing).
- Xiaomi USB drivers + Android platform-tools (ADB/Fastboot).
- Xiaomi Mi Flash Tool for flashing the
Fastboot ROM.Code:
ruby_*_images_OS2.0.*.UMO*XM_*.tgz - A complete backup (a clean Fastboot flash typically erases user data).
How to Flash the Firmware
- Confirm your exact region suffix in Settings → About phone (example: UMOMIXM for Global), then download the matching file such as
.Code:
ruby_global_images_OS2.0.9.0.UMOMIXM_20251111.0000.00_14.0_global_c6feeadcde.tgz - Boot your Redmi Note 12 Pro / Pro+ (ruby) into Fastboot mode and connect it to your PC.
- Extract the downloaded
firmware until you get the Fastboot ROM folder (with images/scripts).Code:
.tgz - Open Xiaomi Mi Flash Tool, load the extracted ROM folder, pick the appropriate flash option (clean flashing is commonly used when fixing severe bugs), then start flashing.
- Reboot after Mi Flash reports success, and allow extra time for the first boot into HyperOS 2 / Android 14.

Frequently Asked Questions (FAQs)
Firmware indexes group codename ruby under the Redmi Note 12 Pro / Pro+ / Discovery 5G family, and the HyperOS download lists for ruby use this naming consistently.
Yes, the listed OS2.0.x.x.UMO*XM builds are shown as HyperOS 2 based on Android 14 on major firmware catalogs for ruby.
Those suffixes represent different regional branches (China, Global, EEA, etc.), and ROM catalogs list separate HyperOS builds per region for the same ruby device family.
Some owners report overheating and higher battery use after HyperOS updates, and a clean flash is sometimes attempted to eliminate corrupted OTA leftovers, but results vary and heat can also be workload-related.
No, these are Fastboot (.tgz) flash files listed as Fastboot packages on ROM catalogs, which are meant for Mi Flash / Fastboot workflows rather than the local recovery updater.
Public changelogs posted by trackers for HyperOS releases are often short and commonly focus on security patch updates and system security/stability improvements rather than detailed bug lists.
