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.

Thank you so much for this. Worked on my Mi A3. Though I had to change slots because it wouldn't boot. Thank you for making it simple to follow.

Perfect, redmi k20 (davinci) worked fine

Saved my phone, MiFlash didn't work on my Windows PC, I went to my Linux laptop and followed your steps and managed to access my phone again. I really appreciate the help.

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?

HELP PLS!
I use a Redmi 13C and followed the steps in the guide to: "image"

Where does it give me a message that I don't recognize, I don't know how to use adb either and it's the 1st time I try a root

I thank you so much.
confirmed working on my bricked (not anymore) poco M6 pro :-)
