Part of Xiaomi guides, HyperOS guides, 2025 guides.

HyperOS 3 on a Pad 5 sounds like it should not exist. The tablet shipped years before this software, and yet here it is running, pulled from the Xiaomi Pad 6S Pro ROM and put together as an unofficial beta port. The vendor uses the official nabu vendor, and the hardware composer port comes from Dagu.

It is a fastboot ROM packaged as erofs, and it is marked unofficial and beta. Read that again before you flash it. This is not something Xiaomi signed off on, so treat it as a test device while you get to know it.

What it looks like

The headline is the refresh rate fix. If you have been on an older HyperOS or MIUI build on this tablet, you know the stutter — the panel not running where it should, scrolling that never quite feels smooth. That is fixed here, completely. For a tablet you mostly read and scroll on, it is the change you feel every single minute.

Around that, the software finally looks like tablet software. The interface is built for the size instead of stretched onto it, and the animations are the newer HyperOS ones you would see on current Xiaomi hardware.

What changed and what is unlocked

This port does not just boot the newer software. It switches on a pile of features that Xiaomi normally keeps for other devices:

• Features for tablets section now shows up in Settings.
• Xiaomi Super Island is enabled.
• Triple-speed game startup for faster app launches.
• Speaker cleaning for clearing dust out of the drivers.
• AI dynamic wallpapers.
• Workstation mode.
• Rhythm Eye Protection.
• Magnet keyboard quick settings toggle.
• AI Master Graphics Engine for the UI.
• Leica camera app version 6.0 — the camera from the phones, on a tablet. Unusual, and a genuinely nice surprise.
• Via Browser built in, so you can strip out the Xiaomi browser if you prefer.

Root is already there

If you want root, this is easier than usual. KernelSU 0.9.4 is built into the kernel, so you do not need to patch a boot image and flash it separately. Root is in place from the moment it boots. SELinux is running in enforcing mode for now, which is the more locked-down of the two modes.

What is broken

Beta means beta. Two things I would want to know going in:

• The -999 APK install error, and lockscreen passwords. If apps refuse to install, or the tablet will not let you set a lockscreen password, reboot to fastboot and run fastboot erase frp from platform tools. That clears the factory reset protection flag and both problems go away.
• Super Island and the three-dot window controls clash. The dynamic Super Island position can overlap the window controls you use to close or minimize apps. Super Island wins the priority, so the controls move rather than the island.

There is also the general roughness you get with any port — an occasional hitch, something in Settings that does not apply until a reboot. Nothing that has stopped me using it.

Who should install it

Install this if you live on the tablet and you care about how it feels. You get the refresh rate fix, a proper tablet UI, root without extra work, and a camera app that is better than anything that shipped on this thing.

Skip it if you need it to be boring. It is unofficial, it is beta, and there is no warranty behind it. If your tablet is a work device you cannot afford to fiddle with, wait. For everyone else, the refresh rate fix alone makes this worth the flash.

Full description from the video

HyperOS 3 on the Xiaomi Pad 5 — a port based on the Xiaomi Pad 6S Pro ROM, with a pile of features unlocked and Android 16 underneath.

This is a fastboot ROM, packaged as erofs, and it's marked unofficial and beta, so go in with your eyes open. The vendor uses the official nabu and the hwc port comes from Dagu. KernelSU 0.9.4 is already built into the kernel, which is handy if you want root without a separate patched image, and SELinux is temporarily in enforcing mode.

The fun part is what's been unlocked. The refresh rate issue is finally fixed, the "Features for tablets" section shows up in Settings, Xiaomi Super Island is enabled, and you get extras like triple-speed game startup, speaker cleaning, AI dynamic wallpapers, workstation mode and Rhythm Eye Protection. The camera app is version 6.0 — the Leica camera from the phones. That's genuinely unusual on a tablet.

Known wrinkle: if you can't install an APK (the -999 error) or set a lockscreen password, reboot to fastboot and run fastboot erase frp from platform tools. The dynamic Super Island position can also clash with the 3-dot window controls, but Super Island wins priority.
