ADB can't find my device in fastboot

Hi,
I want to flash TRWP onto my REDMI 8. However, as soon as I boot into fastboot, adb shell can't find my device anymore.
I've tried everything, installing new Fastboot drivers in Device Manager, new USB cable, other USB port, nothing works. ADB finds my phone in normal mode, but not in fastboot mode:

Try waiting a little longer for it to register your device also make sure that usb debugging is on and that all the latest drivers for your phone are installed on your pc

Na, it won't register, it doesn't find the device.
USB debugging is on.
I've even installed the Xiaomi Tool V2, which supposedly has all the right drivers.

in fastboot mode, its fastboot devices and not adb ;P
if that also fails, try clockwork mod (cwm) universal adb drivers. worked for me for all these years including this phone
also, there are still plenty of roms available iirc, in case they dont show up for olive, you might be able to try mi439

Since you're in Windows, when you plug it in it might/should "bong".
Then you have to find out what is there and whether it has a driver.
ADB and fastboot are usually mutually exclusive.
You might try looking deeper with UsbView.exe https://www.ftdichip.com/Support/Utilities.htm#MicrosoftUSBView
Or you could look in Device Manager
Or you could shell out >$1000 for a hardware USB protocol analyzer.

I got it to work now, thx. Starting from ADB into Fastboot didn't work, but manually booting into FB and the installing twrp did the trick.
