Xiaomi Pad 5 Pro 12.4 (codename dagu) is a large-screen Snapdragon tablet built for smooth multitasking, entertainment, and stylus productivity. However, real-world feedback around Xiaomi/HyperOS updates commonly highlights problems such as abnormal battery drain and overheating, plus occasional UI smoothness complaints that can feel like stuttery animations or inconsistent transitions.
This HyperOS fastboot package (OS2.0.10.0.ULZCNXM) is designed to refresh the full system software, improve stability, and apply system animation optimizations—making it a practical fix for lag, glitches, and software corruption (bootloops/soft-brick) scenarios where returning to clean official firmware is needed.

- Laggy UI or choppy transitions: OS2.0.10.0.ULZCNXM changelog notes system animation optimizations (interrupt animations, transitions, landscape closing animations), which directly targets perceived stutter and UI smoothness complaints.
- Update failures, bootloops, and soft-bricks: Community guidance for the Pad 5 Pro 12.4 points to using the correct fastboot ROM to return to original stock firmware when the device needs a full software restore (especially after failed modifications/updates).
⚠️ Flashing Risks & Disclaimer
- Flashing firmware on Xiaomi Pad 5 Pro 12.4 (dagu / 22081281AC) is high risk, especially when using a fastboot ROM.
- Wrong region/build (CNXM mismatch), incorrect model, flashing interruption, or improper Mi Flash settings can cause hard-brick, endless fastboot, bootloops, complete data loss, partition corruption, system instability, security issues, and warranty/service complications.
- Files, guides, and tools are provided “as is”, with no warranties (express or implied), and no liability for damage, malfunction, or lost data.
- Verify device = dagu, confirm OS2.0.10.0.ULZCNXM (China Stable), and back up all personal data before flashing.
- Proceed only when the flashing method is fully understood; all actions are performed solely at the user’s own risk.

- Bootloader unlocked (commonly required for fastboot flashing on Xiaomi tablets; locked bootloader may prevent flashing).
- Battery charged to at least 50% and a full backup of important data (photos, documents, app data).
How to Flash the Firmware
Method A: Xiaomi Mi Flash Tool (Fastboot ROM.tgz)
- Extract the .tgz fastboot ROM on the PC until the firmware folder (images/scripts) is visible.
- Boot Xiaomi Pad 5 Pro 12.4 (dagu) into Fastboot mode and connect it to the PC via USB.
- Open Mi Flash Tool, refresh to detect the device, and load the extracted ROM folder.
- Select the correct flashing option (be cautious: many options wipe data) and start flashing.
- Wait for completion, then reboot and allow extra time for first boot after reinstalling stock firmware.
Method B: Fastboot Script (flash_all.bat / flash_all.sh)
- Extract the fastboot ROM package and locate the flash scripts included in the ROM folder.
- Reboot the tablet into Fastboot mode and connect it to the PC.
- Run the correct flash script for the operating system (Windows/Linux) from the extracted ROM directory.
- Do not disconnect during flashing; interruption can corrupt partitions and cause a hard-brick.
- Reboot after completion and finish initial setup (data may be wiped depending on script/option).
