Redmi 9A / 9i / 10A (dandelion) Flash File Download (China Stock ROM)

         

Redmi 9a users commonly run into a black screen, with the phone not turning on at all, especially after rooting the device. The stock ROM below is a direct fix for this. This build is made specifically for the Mediatek MT6762G Helio G25 chipset, so confirm your exact model number (e.g. M2006C3LG, M2006C3LVG, M2006C3LI, M2006C3LII, M2006C3LC, 220233L2G, 220233L2I, 220233L2C) before downloading.

Running into a bootloop, a dead boot, or a Mi logo that won't go away on your Redmi 9a (codename dandelion)? 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.

One thing worth knowing upfront — fastboot ROM flashing wipes the phone completely, so only go that route if you're fine starting fresh. For a lighter repair that doesn't touch your files, the recovery ROM is normally the better choice.

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).

Downloading in multiple parts? Keep every part inside the same folder before extracting — the archive won't open correctly if a part is missing.

Tools You'll Need

Get the flashing tool and the right USB driver set up on your PC before you start — in most cases, a failed flash has more to do with a missing driver than with the firmware file.

Mi Flash Tool (All Versions) USB Driver (All Brands)

How to Flash Redmi 9a Using Mi Flash Tool

1. Download the fastboot ROM and extract it fully — don't skip extraction, Mi Flash Tool won't read a zipped folder.
2. Install Mi Flash Tool from the link above and open it.
3. Power off the phone, then hold Volume Down + Power together to boot into Fastboot mode.
4. Connect the phone to your PC using a good-quality USB cable — cheap cables are a common cause of connection drops mid-flash.
5. In Mi Flash Tool, click "Select" and point it to the extracted firmware folder.
6. Once the COM port is detected, hit "Flash" and let it run — don't disconnect the phone during this step.
7. 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?
Make sure the codename matches dandelion exactly, as listed above. Using firmware meant for a different variant or region can brick the device.
