Redmi a7 pro / poco c81 pro users commonly run into random reboots, with the phone restarting on its own, especially after a failed TWRP or custom recovery flash. The stock ROM below is a direct fix for this. This build is made specifically for the Unisoc T8300 chipset, so confirm your exact model number (e.g. Global - 25128RN17A, 25128RN17Y | Latin America - 25128RN17L) before downloading.
Whether your Redmi a7 pro / poco c81 pro (codename: arctic) 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.
Before you pick a file: fastboot flashing means a full reset, so use it when the phone is genuinely stuck or dead. If you're just trying to repair the system without losing data, go with the recovery ROM instead.

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).

Tools You'll Need
Before flashing, make sure you have the flashing tool and the correct USB driver installed on your PC — most flashing failures actually come down to a missing or outdated driver rather than the firmware itself.
How to Flash Redmi a7 pro / poco c81 pro 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 (arctic) shown in the table above. Flashing firmware built for a different region or variant can leave the device unusable.
