Please help me out, I tried installing TWRP and then got a bootloop with no recovery or fastboot

I followed this video on youtube
and then got stuck in a bootloop with no recovery or fastboot.
After that I followed this video
that is supposed to unbrick redmi note 9 with no Auth
I installed python, pyserial json, installed cdc-acm.inf
and got the phone mediatek port showing up in libusb and installed the filtered driver
After I went into updated BTP folder and ran the two .bat files and now my phone screen is black,
nothing happens. Not even a bootloop.
I did try to complete the video and opened SP Flash Tool but got a rid bar stack at DA 100% for a few minutes then got an error
Is there any solution out there to unbrick this phone
I would really appreciate it. Thank you
EDIT: When I try to connect the usb port to the phone now I get this
`
Windows has stopped this device because it has reported problems. (Code 43)
A request for the USB device descriptor failed.`
On windows 10

I tried following this, "adb devices" doesn't show any listed device when I connect my phone, and now windows 10 gives error code 43 when I connect it, which didn't happen before.

Went to repair shop, he pressed power button with volume up or down, and the bootloop started again, I've been trying that all day yesterday but couldn't manage to show the screen.
Anyways I went back home after he did that, and followed the second video I linked and now my Redmi is working fine. The issue is solved.

Always Triple check the files that you're about to flash if it's built for you rom or not. And res threads carefully. Join on telegram also.

You're absolutely right. It's just that the video had many likes, the top comments were saying good things and in the description he only mentioned version 12.0.6 to cause a brick where I had 12.0.1 which is the one every youtube video installed custom ROMs on. I should've been more careful tho, I guess I'll stick to MIUI to avoid any issues although I hate it.

But the ROM wasn't installed and the device is locked now. The problem is then i try to use miflash_unlock-en-5.5.224.24 i am getting this error message - you are unlocking a special device which should do with special permissions.
Does anyone has any idea how to bypass it ?

Sorry, this is the place for POCO F3, Mi 11X or Redmi k40, (all are the same device basically) you'll have to go to the Mi11 Ultra device specific XDA thread https://forum.xda-developers.com/f/xiaomi-mi-11-ultra.12139/

Hi, has a solution been found in the meantime? I'm on MIUI 13 (A12) too, but have been for a few months now. The smartphone just shut down in my hands and shows no signs of life.

the system has been destroyed

Good night.
My name is Daniel, i live in Brazil.
I'd like to ask your support to help me restoring my MI 8 device.
It got stucked in the "the system has been destroyed" screen after a system update.
I have a certain kinda knowledge on restoring devices, but this one is killing me.
I went to your website https://xiaomifirmwareupdater.com/ and found the mi8 model, downloaded the Redmi 8 Global version.
But I don't know what do with the files using the platform-tools tool.
Normally there is a file called "flash_all.bat".

If your bootloader is unlocked, try flashing rom with miflash tool. It has a chance of working. Update us with the progress.
