Fastboot Problem (Freezing, probably not drivers)

Hello,
I've got a problem when trying to load fastboot that I haven't been able to find a solution for here. I'm hoping someone else has run into this and can help. My phone (H811) seems to freeze upon entering fastboot mode. I have...
Flashed 20i using TWRP
Enabled OEM Unlock and Debugging
Uninstalled and Reinstalled drivers in every imaginable configuration over the past two days
Flashed (and completely wiped internal storage) the 20i KDZ
Continued to muck around with drivers
Everything is fine when connecting to my PC, ADB has no issues. I run into trouble when rebooting (via ADB) and the phone freezes. The power button is unresponsive and I have to pull the battery to exit fastboot. My device manager shows -something- is connected after entering fastboot, but so far I haven't been able to find a working driver for that.
Thanks

Fastboot not working

Hey guys,
I have a problem while trying to flash TWRP on my Xiaomi Mi5. TWRP was installed earlier and worked completly fine with flashing custom ROMs, flashing OpenGAPs or rooting the device but now for some reason TWRP got lost and the standard Xiaomi recovery is on the device again. Installed was MIUI 8 in the Dev-Version (weekly patches) for the last half year and was the last ROM flashed with TWRP.
And now comes the problem when i try to install/flash the twrp image via fastboot: If i reboot the device in fastboot mode it shows the following behaviour:
1. It show the fastboot logo on the screen for about 10-30 seconds before it reboots automaticly (doesn't matter if i connect it via USB before or while it shows the fastboot logo)
2. While it shows the logo on the screen and it is connected via USB it's not showing up in the console when i list the all connected fastboot devices
I can still use the devices standard recovery and the installed OS, just the fastboot part seems to be brocken. Am i missing a driver on my computer or something?
Has somebody else an idea how i can solve this automatic reboot in fastboot mode?
Edit: If this Thread belongs into another catagory, i apologize
Make sure minimal adb and fastboot are installed in your pc. After that, enable usb debugging from developer options and connect with your pc and let it there for a while to install drivers on your pc. Then go to twrp and your phone should no longer reboot after your connect usb. Flash twrp here.

ADB and FASTBOOT installed -> checked!
USB-Debugging enabled -> checked!
Windows installing drivers automaticly -> unsure. Windows didn't installed anything it just notified me that there is a new USB-Device (Device is also showen as ADB-Device and appears in the list of connected adb devices)

To that: TWRP is not installed on the phone anymore. I just have the standard xiaomi recovery where i'm not able to flash a .zip or something. I can just wipe all my data there
The reboot behaviour also appears if i switch to fastboot via "adb reboot bootloader" command while spamming "fastboot devices" to check if it appears before it reboots.
The standard recovery is usable as it should be without any reboots only the fastboot mode seems brocken.

Weird. Everytime this sorta problem happens to me, its because windows didnt have the drivers installed after you connect your pc with debugging enabled. So thats the only troubleshooting i did to fix things. And yeah it did show me drivers installed correctly after i connected phone with debugging enabled. Maybe for some reasonn those drivers arent being installed to windows. Give it more time maybe? [emoji23]

I too have the same problem..****
Install MiFlash on your PC and try again, the device will show up correctly on fastbook devices command. It was a USB drivers issue in my case.

Red MAgic 3 recovery problem

I have a Red Magic 3 and im having issues.
Its in fastboot but when i go to boot to recovery it just goes to fast boot. i got to boot it to android and the same thing. Fastboot i can see it with fastboot devices but i cant in adb devices. When i plug it in with fastboot its not in device manager but when i put it into EDL mode it shows in device manager. Tried putting twrp on it and it just goes back to fastboot and relocks the bootloader. I used the recovery tool and its giving me this error.
Any idea on what could be doing this? Or how i can fix this?
Wont let me post a link to a picture. But its saying reset EDL mode and download failed. I got my firewalls all disabled. Running windows 10 pro.
Help me please

Fastboot black screen only? Need help asap

Hi guys so my device is on global miui 12.0.6.0 stable and whenever i check for updates it says its the latest but I know there is an android 11 already, my device is still on android 10.
So next step is to unlock adb and fastboot right so I can update my device.
I did all the steps necessary.
OEM Unlock is on
MI account is connected on (mi unlock status)
usb debugging is on
install via usb is on
usb debugging security settings is on
No password (lockscreen)
Other things I've done:
I installed the Miui 12 on the check update screen twice
I factory reset on settings
I cleared all data on recovery settings (stock recovery only of miui)
andd still no LUCK! I badly need some of you high IQ guys here to help me resolve this please My mind hurts its like the factory of fastboot of this phone has somehow got corrupted....
I can hear a sound when connecting via usb when on black screen fastboot mode
I can even access adb commands like " adb reboot bootloader & adb reboot fastboot " and they all leads to the BLACK SCREEN FASTBOOT (NO LOGO) MODE T.T

after tweaking and tweaking it does. Fortunately MI Unlock also works even if its just a black screen fastboot mode. so weird but it is what it is

I believe that this shouldn't modify fastboot, try to reflash the latest and original MIUI rom using flash_all.bat (don't use flash_all_lock.bat)
It should fix any corrupted partitions. Or it may not do anything.
