POCO M5 / Redmi 11 Prime 4G (rock) HyperOS 1 Android 14 Fastboot ROM Download – Global / EEA / India / RU / TW / TR / ID + TWRP

[Daniel]

The files listed here are official HyperOS 1 Android 14 Fastboot ROM packages for the POCO M5 / Redmi 11 Prime 4G with codename rock, released for multiple regions (Global, EEA, India, Russia, Taiwan, Turkey, Indonesia). Owners of this budget phone commonly complain about average camera quality, frame drops in heavy games, and occasional lag or battery drain after updates, issues that sometimes improve after a clean flash of a newer stable HyperOS build or a reset on the correct regional firmware.

Important Warning for POCO M5 / Redmi 11 Prime (rock)​

• Only flash ROMs built for codename rock (POCO M5 / Redmi 11 Prime 4G); using firmware for any other Xiaomi model or codename can hard-brick your phone.
• Always match the region code in the version name (ULUMIXM / ULUEUXM / ULUINXM / ULURUXM / ULUTWXM / ULUTRXM / ULUIDXM); cross-flashing regions is risky and may break network features or OTA updates.
• Fastboot flashing requires an unlocked bootloader and may wipe all user data depending on the selected flash mode, so back up internal storage before you begin.
• TWRP images and other custom recoveries are third-party tools; using them incorrectly can cause bootloops or encryption issues, so they are recommended only for advanced users.

3. Boot the POCO M5 / Redmi 11 Prime into Fastboot mode, connect it to your computer with a USB-C cable, and confirm that it is detected with

   fastboot devices

   or inside Mi Flash.
4. Open Xiaomi Mi Flash Tool, select the extracted ROM folder (for example, the folder from OS1.0.12.0.ULUMIXM), choose the appropriate flash option (note that some options wipe all data), and start the flashing process.
