POCO C311 users commonly run into issues like RAM Extension (Memory Virtualization) Stability Bugs, especially when dealing with Download Manager Pause/Resume Loop Errors. The stock ROM below is a direct fix for this. This build is made specifically for the Mediatek MT6765G Helio G35 chipset, so confirm your exact model number (e.g. POCO C3 - M2006C3MI India, POCO C31 - 211033MI India) before downloading.
Whether your POCO C311 (codename: angelicain) 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.
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
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tool and the correct USB driver installed on your PC — most flashing failures actually come down to a missing or outdated driver rather than the firmware itself.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 POCO C311 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 (angelicain) shown in the table above. Flashing firmware built for a different region or variant can leave the device unusable.
How to Unlock Bootloader on POCO C311
Before you start: Unlocking erases all data on the phone and lowers its security. Back up first.
Steps:
- Log in to your Mi account on the phone.
- Enable Developer options: Settings → About phone → tap OS/MIUI version 7 times.
Bind your account: Settings → Additional settings → Developer options → Mi Unlock status → Add account and device. This needs a SIM card and mobile data turned on. - Download the Mi Unlock tool on your PC and sign in with the same Mi account.
- Enter Fastboot mode: power off the phone, then hold Power + Volume Down.
- Connect the phone to the PC by USB and click Unlock in the tool.
Good to know:
- Xiaomi usually enforces a waiting period (often 72 to 168 hours). The tool will tell you how long, and the account must stay bound to the phone during that time.
- Newer HyperOS versions have stricter unlock rules in some regions, so check Xiaomi's official unlock page for your region.
- After unlocking, some banking or payment apps may stop working, and Widevine L1 (HD streaming) may be lost.
- Don't flash any custom ROM or tool on a phone until you've found a confirmed guide for that exact model on XDA or the Xiaomi community.
If you hit an error like "Couldn't verify device" or a waiting-time message, let us know in the comments and we'll help.
