How to flash MIUI Fastboot ROM from Linux

• Download the fastboot ROM suitable for your device from the MIUI site and extract the downloaded archive [edit: MIUI page is dead. Use Xiaomi Firmware Updater]
• Download and extract the Android SDK Platform Tools
• Make sure adb and fastboot (components of platform-tools) are in your path

$ export PATH=path/to/android/sdk/platform-tools:$PATH

• Connect your device to your computer using a USB cable and enable USB Debugging in your device's settings. Check if your device is detected.

$ adb devices

• If device is listed, reboot to bootloader

$ adb reboot bootloader

• Check if your device is detected by fastboot

$ fastboot devices

• You may need to use sudo before fastboot if you get a permission denied error
• There are two scripts for flashing the ROM:
  1. flash_all.sh - Flash ROM and erase user data
  2. flash_all_except_data_storage.sh - Flash ROM without erasing user data
• Whichever script you decide to use, make sure that the interpreter is mentioned at the top of the script like

#!/bin/sh

• If the above line is missing, add it to the top of the script
• Make the script executable (I've chosen flash_all.sh)

$ cd path/to/extracted/ROM/archive
$ chmod a+x ./flash_all.sh

• Run the script

$ ./flash_all.sh

• You may need to run sudo ./flash_all.sh if you had to use sudo with fastboot
• Sit back and relax. The script needs no user interaction. After flashing the ROM, the script will reboot your device.
• Reboot will take quite a bit of time. Don't panic.

worked perfectly for Xiaomi Poco F3

Thank you. I'll treasure this in my brain.

Had I known there was just a script in the archive I wouldn't have searched everywhere how to do it for 15 minutes. Would have been easier to extract it and see for myself. You shouldn't exactly run a flashing tool on a VM... (I'm on Linux.)

confirmed working on Redmi Note 10s (rosemary)

Is this method work on locked bootloader

Is this method work on locked bootloader

No

I can confirm this method works on Redmi Note 10S (rosemary) device.

Works on Mxlinux 21.3. uncompress the ROM (from xiaomi.eu). Open a terminal in it and run ./linux_fastboot_first_install_with_data_format.sh (for me)
No brainer on MI 10t Pro.
Thanks!

Worked on Poco m4 pro 5g

I tried flashing my Poco F5 and encountered an error:

sending 'cust' (2097152 kb) failed (remote: 'requested download size is more than max allowed')

The script stopped due to this error, but I executed the remaining commands manually. It worked, but I'm concerned if there will be any issues later on. Can anyone enlighten me?
