Redmi note 9 / Redmi 10X 4G users commonly run into the device getting stuck in Recovery Mode, 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 Mediatek MT6769Z Helio G85 chipset, so confirm your exact model number (e.g. REDMI Note 9 M2003J15SS (Global), M2003J15SG (Global NFC), M2003J15SI (India) | REDMI 10X 4G M2003J15SC (China)) before downloading.
Running into a bootloop, a dead boot, or a Mi logo that won't go away on your Redmi note 9 / Redmi 10X 4G (codename merlin)? 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?
It's easy to grab the wrong file here, so let's keep it simple. A fastboot ROM is the full firmware set, flashed via Mi Flash Tool on a computer — it resets the device entirely, which is exactly why it works for bootloops, dead boot, or a phone stuck at the logo. A recovery ROM instead runs from the phone's own Mi Recovery menu, and is meant for updating, downgrading, or repairing software without wiping your data (backing up first is still a smart move).

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.
How to Flash Redmi note 9 / Redmi 10X 4G 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?
Always double-check the codename against merlin from the table. Flashing the wrong region or variant's firmware can leave the phone unusable.
