Amazing share dev, keep up to great work as always

Not able to enter fastboot
Hi,
Following works
"adb devices"
"adb reboot recovery"
However when I do
"adb reboot bootloader"
device restarts and gets stuck at "YUREKA BLACK" "POWERED BY android".
Also when I start device with Volume Down+Power button, I get into FFBM.
It just has variety of test options and no boot to bootloader/recovery.
Two button at bottom are shutdown and reboot.
Device is manufactured in 2019.
Any ideas how to get into bootloader mode.
Edit: Solved, issue with driver in fastboot mode.

This are some of the output I get from ADB
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
List of devices attached
0123456789ABCDEF recovery
And if I uses "adb reboot fastboot" it does, but then the output of "adb devices" and "fastboot devices" is null
I have tried a lot commands, but I always get the same results <waiting for device>
My drivers are working.
I already unplug/plug/restart the table but the <waiting for device> is still there
I still tried with this tool http://forum.xda-developers.com/showthread.php?t=1951254 but it doesnt work, event trying a fastboot command manually doesn't work.
Any ideas!! please help!

How to block bootloader on xt1799-2

I will try to describe exactly what I did. I warn you that if you want to repeat this, then do everything at your own risk!
Original message
1. The cleanest installation possible​
We do a COMPLETE cleanup and format the DATA in TWRP not lower than version 3.4... then reboot into bootloader and connect to the PC with a good cable. Run Fastboot on the PC in the command line in turn enter the following commands:
fastboot devices
fastboot erase all
fastboot reboot bootloader
2. Install motoXT1799-2_GLOBAL_2021.02.20_oreo.zip​
Use the firmware from here: motoXT1799-2_GLOBAL_2021.02.20_oreo
3. Install Magisk​
The latest version of Magic-v22.0.apk must be installed and Magisk-v22.0.zip
4. Go to the developer menu​
In the developer menu, we give permissions to unlock the OS bootloader, as well as give permission to debug via USB.
5. Run adb Fastboot on the command line​
The phone must be connected to the PC via USB. We enter the command adb devices on the smartphone, a dialog box should appear to allow debugging this device or something like that, respectively, we give permission.
Next, we reboot into the bootloader with the command adb reboot bootloader
6. Blocking​
Previously, we copy the stock recovery.img to the folder with adb Fastboot
Enter the commands:
fastboot flash recovery recovery.img
fastbo fastboot flashing lock
We reboot into the system.
7. Delete Magisk as unnecessary​
To do this, go to the program select delete see two items select first "restore partitions or something like that" then delete.
8. Do a factory reset​
If everything is done correctly, we get a device with Oreo Android 8.1.0 as if it came out of the factory.
