Redmi note 9 - EDL flash - Need authorized Mi account

Hello,
i have problem with flashing redmi note 9 pro in edl mode.
I need authorized Mi account. Can somebody help me with it? Via teamviewer? Reward certain!
Thank you very much, Lukas
Edl mode is basically service center repair from xiaomi.You need ifu dongle or contact repair center.or black market not recommended do.
This section is for MERLIN (redmi note 9).
If you want to use sp flash tool, you need to flash the stock rom preloader using V12.0.4.0 (or lower). (It will works perfectly with lower preloader binary version).
With an older preloader version, your phone will can receive DA files and accept flashing with NO auth.
Everything you need to do is plug your phone in usb (without press any key, if you press any key it will enter in EDL mode and requests authenticaion).
Here, are PRELOADER binaries for flashing: https://forum.xda-developers.com/t/...omi-redmi-10x-4g-xiaomi-redmi-note-9.4221081/
Here, are DA files for flashing using flash tool: https://forum.xda-developers.com/t/...omi-redmi-10x-4g-xiaomi-redmi-note-9.4209767/
Only after it, you can use sp flash tool again.

Do I need to flash it via fastboot ?
I have already done it but my device is detected in com ports for only 2 seconds and then charging screen appears. I have also installed device filter(libusb).

Everything you need to do is relock bootloader and flash the stock miui again and you got warranty back.

i have the same problem
my pc isn't detecting my phone at all and i can't enter fastboot mode or shut it down
As linked by @VD171 you have to delete the misc partition created by the incompatible TWRP, so do:
1 - turn on your phone, your screen probably is black, but connect to your pc and do:
adb devices
2 - it should detect the device, then do:
adb reboot bootloader
fastboot devices
fastboot erase misc
after that you should be able to restart to fastboot mode again

"infinite boot loop showing only the Redmi logo,
Can't access recovery with power+vol down, can't enter fastboot, can't connect it to a computer either."
I can enter fastboot but the other problems are true, so is this method viable for me? do I need to follow some other guide or will this work?

Question Locked Redmi note 12 Pro plus miui 14chi Chinese rom

Hi ,I have a Chinese rom Redmi note 12 pro plus, I managed as far as unlocking boot loader and tried flashing global rom but it has bricked it and stuck in boot loop and can't reset either, any help would be appreciated
Looks like you have locked the bootloader again. Try unlocking it again.
When flashing a new rom make sure to select "clean all" and NOT "clean all and lock" which is the default selection.

I can't as it is stuck in boot loop and recovery won't work either
Does it not boot to fastboot mode? Volume down + power?

Yes it does it start to boot up then goes straight to fastboot
Fastboot is exactly what you need. Connect it to a PC in fastboot mode and unlock the bootloader using the Mi Unlock tool.
For further help visit the redmi note 12 forum which I have linked in the post above.

What do you think I could do to unlock?
As I said, try unlocking the bootloader using Mi Unlock tool. Give it a try even if you can't boot the phone to system.
And post your question in the redmi note 12 forum.
