can you link a guide to flash custom firmware (lineageos) on debian on a redmi 9c or help me flash it? (linux.community)

most guides I found online are for windows based computers and those that even name linux are outdated.

Linux distro I run: debian 12.5, adb and fastboot installed through apt
Phone I want to experiment with: redmi 9c
Firmware I'm installing: https://xdaforums.com/t/rom-13-unofficial-lineageos-20-0-unified-for-redmi-9a-9c-10a-blossom.4609367/

fastboot devices recognizes the device and I can also boot the phone to fastboot: it shows a black (not blank) screen with the word FASTBOOT printed orange.

I tried following https://android.gadgethacks.com/how-to/complete-guide-flashing-factory-images-android-using-fastboot-0175277/ but fastboot flashing unlock and fastboot oem unlock return FAILED (remote: 'Token Verify Failed, Reboot the device ')

developer options and OEM unlocking are both activated on the device

With some phones you need to go through extra steps to be able to do OEM unlocking. Looks like it is the case here, see the steps in the FAQ linked here : https://en.miui.com/unlock/download_en.html

I've never used miui devices but I think you need to make an account and use this https://en.miui.com/unlock/download_en.html so you will probably need to have wine installed to run it, unless it has a native linux version in the zip file. Then you should have an unlocked bootloader

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
