How to Flash Official ROM (Mi Flash Tool)
Use this method to unbrick your phone or restore official MIUI for POCO firmware.
- Boot into Fastboot mode (Power + Volume Down).

How to Install TWRP & Flash Custom ROMs
Use this method to install the Xiaomi.eu custom ROM or explore the vast world of other ROMs.
What is TWRP? TWRP (Team Win Recovery Project) is a powerful custom recovery that replaces your phone’s basic stock recovery. For a device like the POCO F1 with a massive developer community, TWRP is the key that unlocks the ability to flash custom ROMs, create full system backups (Nandroids), gain root access, and much more.
Disclaimer: This is an advanced process. Proceed at your own risk.
- Unlock the Bootloader: This is a mandatory first step. Use the official Mi Unlock Tool.
- Flash TWRP:
- The TWRP download is a .zip file containing the recovery .img and flashing scripts. Extract it.
- Boot your phone into Fastboot mode (Power + Volume Down) and connect it to your PC.
- Run the fastboot-flash-recovery.bat script from the extracted folder to install TWRP.
- Boot into TWRP: After flashing, immediately boot into recovery by holding Power + Volume Up.
- Install Custom ROM:
- In TWRP, it’s recommended to first go to “Wipe” and select “Format Data” to remove encryption.
- Transfer the Xiaomi.eu .zip ROM file to your phone.
- In TWRP, tap “Install,” locate the xiaomi.eu…zip file, and swipe to confirm the flash.
- Reboot your system once the installation is complete.
FAQs
Q1. What made the POCO F1 so famous?
It was a true “flagship killer” that offered a top-tier Snapdragon 845 processor, found in phones that cost two or three times as much. This uncompromising focus on raw speed, along with a large battery and liquid cooling, made it an instant legend among gamers and power users.
Q2. Why is the custom ROM community so large for the POCO F1?
POCO was very developer-friendly from the start, providing kernel sources quickly and having a straightforward bootloader unlocking process. This, combined with its powerful hardware and low price, made it the perfect canvas for developers to create and port a vast number of custom ROMs.
Q3. What was the final official update for the POCO F1?
The POCO F1 launched with Android 8.1 Oreo and received its final major OS upgrade to Android 10. The MIUI 12 builds provided on this page are the last official software updates for this model.
Q4. The Xiaomi.eu ROM is a .zip file. What does that mean?
It means it is a “Recovery ROM” that must be installed from within a custom recovery environment. The provided TWRP file is the tool you need to flash first, which then allows you to install the Xiaomi.eu .zip file.
Troubleshooting
- Drivers: If your PC does not recognize the phone in fastboot mode, reinstall the Xiaomi USB drivers and run Mi Flash Tool as Administrator.
- Fastboot errors:
- “error: not catch checkpoint” → This common error means you have selected the wrong folder. In Mi Flash Tool, be sure to select the parent folder that was created when you extracted the .tgz file, not the images folder inside it.
- “Anti rollback error” → You are attempting to flash an older firmware version than what is currently on the device. Xiaomi’s Anti-Rollback Protection (ARB) prevents this.
- TWRP Issues:
- TWRP asks for a password → This means your phone’s storage is encrypted. The standard fix is to go to the “Wipe” menu in TWRP and choose “Format Data”. This will erase everything on your internal storage.
- Stuck on boot after flashing → If the phone doesn’t boot up after flashing a custom ROM, reboot to TWRP, perform a full wipe (Cache, Dalvik, System, Data), and then re-flash the ROM .zip file.
