POCO C81x / POCO C71 / Redmi A7 / Redmi A5 users commonly run into the phone hanging on the boot animation and never reaching the home screen, especially after unlocking the bootloader. The stock ROM below is a direct fix for this. This build is made specifically for the Unisoc T7250 chipset, so confirm your exact model number (e.g. POCO C71 (25028PC036 25028P003Y 25028P0031 25028PCOSL) REDMI A5 (25028RNCOG 25028RNC34 25028RNCJY 25028RNC31 25028RNOSE) REDMI A7 (26020RNB4A 26020RNB41 26020RNB4L) POCO C81x (20020PCB4) before downloading.
If your POCO C81x / POCO C71 / Redmi A7 / Redmi A5 (codename: serenity) is stuck on the Mi logo, stuck in a bootloop, showing a dead boot screen, or you flashed a custom ROM and now want to get back to MIUI/HyperOS, you're in the right place. Below you'll find every available fastboot and recovery firmware version for this device, along with working download servers and a flashing walkthrough that doesn't skip steps.
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?
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 POCO C81x / POCO C71 / Redmi A7 / Redmi A5 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?
Make sure the codename matches serenity exactly, as listed above. Using firmware meant for a different variant or region can brick the device.
