Xiaomi Pad 9 Pro Max users commonly run into the phone hanging on the boot animation and never reaching the home screen, especially after installing an incompatible app or theme. The stock ROM below is a direct fix for this. This build is made specifically for the XRing O3 chipset, so confirm your exact model number (e.g. M367FC - China) before downloading.
Running into a bootloop, a dead boot, or a Mi logo that won't go away on your Xiaomi Pad 9 Pro Max (codename yingtian)? This page covers every fastboot and recovery firmware build currently available for the device, plus working download servers and a flashing guide you can actually follow start to finish.
A quick heads-up before you scroll further: pick the fastboot ROM only if you're comfortable with a full wipe, since it resets the phone completely. If you just need to patch or repair the system without losing your data, the recovery ROM is usually the safer bet.

Fastboot vs Recovery ROM — Which One Do You Need?
People often download the wrong file the first time, so here's the short version. A fastboot ROM is a complete firmware package meant to be flashed through Mi Flash Tool on a PC — it wipes the device and reinstalls everything from scratch, which makes it the go-to fix for bootloops, dead boot, or a phone that refuses to start. A recovery ROM, on the other hand, is flashed through the phone's built-in Mi Recovery menu and is generally used to update, downgrade, or repair the system without touching your personal data (though a backup is still recommended).

Tools You'll Need
Make sure the flashing tool and correct USB driver are already installed on your computer before you begin. More often than not, a flash fails because of a driver problem, not the firmware itself.
How to Flash Xiaomi Pad 9 Pro Max Using Mi Flash Tool
- Download the fastboot ROM and extract it fully — don't skip extraction, Mi Flash Tool won't read a zipped folder.
- Install Mi Flash Tool from the link above and open it.
- Power off the phone, then hold Volume Down + Power together to boot into Fastboot mode.
- Connect the phone to your PC using a good-quality USB cable — cheap cables are a common cause of connection drops mid-flash.
- In Mi Flash Tool, click "Select" and point it to the extracted firmware folder.
- Once the COM port is detected, hit "Flash" and let it run — don't disconnect the phone during this step.
- The phone will reboot on its own once flashing finishes. First boot can take a few minutes longer than usual, so give it time.
Common Flashing Errors and How to Fix Them
"Auth file needed" — this usually shows up when the connected Mi account isn't authorized for flashing. You'll need an authorized account, or a test-point based flash for unlocked devices.
"COM port not detected" — almost always a driver issue. Install the Qualcomm/MediaTek USB driver from the link above, then put the phone back into EDL or Fastboot mode and try again.
"Flashing failed" partway through — try a different USB cable or port first; if that doesn't help, re-extract the firmware in case a file got corrupted during download.
Frequently Asked Questions
Is this firmware official?
Yes, these are unmodified stock builds pulled directly from Xiaomi's own update servers.
Will flashing delete my data?
Fastboot flashing wipes the device, so back up anything important first. Recovery flashing is less destructive but a backup is still a good idea.
My model number doesn't match exactly — can I still use this?
Stick to the exact codename (yingtian) shown in the table above. Flashing firmware built for a different region or variant can leave the device unusable.
