Redmi 12 5g / poco m6 pro 5g users commonly run into a hard brick, where the phone shows no signs of life, especially after downgrading the firmware. The stock ROM below is a direct fix for this. This build is made specifically for the Qualcomm SM4450 Snapdragon 4 Gen 2 chipset, so confirm your exact model number (e.g. 23076RN8DY (Global NFC), 23076RN4BI (India), 23077RABDC (China), Japan (23076RA4BR, XIG03, A401XM)) before downloading.
Whether your Redmi 12 5g / poco m6 pro 5g (codename: sky) is soft-bricked, hanging on the boot logo, or you just want to move back to stock MIUI/HyperOS after trying a custom ROM, this guide has what you need — every fastboot and recovery firmware build for this device, reliable download servers, and a full flashing walkthrough.
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?
This trips up a lot of people, so here's the difference. A fastboot ROM is flashed from a PC using Mi Flash Tool and completely resets the device — the right pick when you're dealing with a bootloop, dead boot, or a phone that won't start. A recovery ROM is flashed straight from the phone's Mi Recovery menu and is built for updating, downgrading, or fixing software issues while keeping your data intact (though a backup never hurts).

If the file comes in multiple parts, place all of them in one folder before you try to extract — missing even one part will stop the archive from opening properly.
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 Redmi 12 5g / poco m6 pro 5g 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 sky from the table. Flashing the wrong region or variant's firmware can leave the phone unusable.
