This is a general guide which should not differ too much on how to unlock Xiaomi devices and flashing recovery and custom ROM.

 

Hardware Needed:

• Well charged Xiaomi / Poco phone (>70%)
• Mi account
• Working SIM Card that can receive SMS
• Compatible USB-C Cable (if in doubt, use the factory supplied one)
• Windows Computer (if in doubt, Windows 10)

 

Software Needed:

• Mi Unlock (this is a flasher tool for Xiaomi / Poco devices)
• ADB Android USB Driver for Windows
• SDK Platform Tools for Windows
• Custom Recovery (this example will use OrangeFox Recovery for Poco F3, detailed below)
• Custom ROM for your phone (this example will use ArrowOS for Poco F3, detailed below)
• Xiaomi Firmware (this example will use firmware for Poco F3)

 

Enable Developer Options: Go to Settings > About Phone > keep tapping MIUI version until you see "developer mode is enabled"

 

Enable USB Debugging and OEM Unlocking: Go to Settings > Additional Settings > Developer Options > and toggle USB Debugging + OEM unlocking

 

 

Unlock Bootloader:

• Extract the ADB USB Driver into a folder
• Install ADB USB Driver by going to Windows Settings > search and open Device Manager > Click on your DESKTOP > Action > Add Legacy Hardware > select .inf file
• 
• Reboot PC
• Insert SIM card into phone
• Sign in the phone to Mi Account
• Disable Wifi and go to Developer Options > Mi Unlock Status > Add account and device
• Open Mi Unlock Tool
• Sign in to Mi Unlock (if normal sign in fails, use QR sign-in, and go to Xiaomi Phone > Settings > Mi Account > Scanner icon)
• Mi Unlock tool will check whether your Mi Account has bootloader unlock permission.
• Follow on-screen instructions: Turn off phone, press and hold Volume Down and Power button to boot into booloader mode
• Connect the USB-C Cable
• 
• Unlock the phone and wait (obviously do not disconnect or power anything until it completes)
• First timers may fail to unlock, and required to wait 168 hours to try again
• 
• Phone will reboot automatically and first boot takes a while
•  
•  

 

Flash New Recovery, Firmware and Custom ROM:

• Download and extract firmware (if in doubt, always use latest Global + Stable)
• Download and extract the SDK Platform Tools
• Download and extract OrangeFox Recovery
• Copy the recovery.img from Ofox folder to Platform tools folder like so:
• 
• run command prompt (type cmd on windows search icon)
• navigate to the platform tool folder by typing "cd c:/folder/path/here
• type fastboot boot recovery.img
• 
• turn off phone and enter fastboot mode
• Connect the USB-C Cable to your computer
• Orangefox will boot
•  
• Download the correct ROM for your phone
• Connect the USB-C Cable to your computer
• Power Off Tablet
• Press and Hold Volume Up and Down buttons
• Connect the USB-C Cable
• Bootloader screen will appear
• Press Volume Up button once to enter Download Mode
   
•  

 

               

 

 

• Then click START, flash will proceed (obviously do not turn off or disconnect anything until its complete)
   

               
 

• Once Complete, Odin will show "PASS". and tablet will auto reboot.
   

               
 

• Again with a new firmware, first boot will take a whle
