booting... FAILED (remote: unknown command)

Whenever I try to use the command
fastboot boot [whatever].img
I get this message
downloading '[whatever].img'...
OKAY [ 0.699s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.699s
Has anyone else encountered this?
Bootloader is unlocked, it's a fresh and clean install of the stock software, up to date as of Mar 31, 2020. I'm try to install a custom rom, but first I have to boot into TWRP recovery, but I cannot.
Any suggestions?

From Android 10, use the following to fastboot boot images:
fastboot flash boot [whatever].img

Unable to restore via MSMTool

I have made huge mistake and i dont know what to do and would really appreciate some help. I was on Open Beta 17 with magisk and twrp and i decided i wanted to revert the stock using msmtool. I have used it before so i know about all the drivers to install and how to get to edl and so on. So i started the msm software and hit start, but a few seconds into the flash i got the an error "firehosewritedata failed" and since then my device cant be recognised by my computer and its not booting up or even showing that its charging. I tried reinstalling the drivers and trying msmtool but the device isnt recognised at all.
Booting into fastboot only says Update download failed please check your download flow is right

Putting it to charge also brings the same Update download failed message every 3 seconds

Hold power off and volume up together for like 15-30 seconds while unplugged

OP 6 stuck with no IMEI/MEID/BASEBAND/MAC address

Hi,
My OP6 is stuck and keeps restarting. I have flashed all stock roms via MSMtool from hydrogen OS to Oxygen OS 10.3.5. Even tried fastboot rom flashing with no luck.
Flashed stock OS via twrp still nothing.
I do have a backup of my EFS partition but flashing that via fastboot/terminal makes no difference in any stock OS.
I have searched every topic related to this particular error but didn't find any fix yet so was forced to create a new thread.
Need urgent help, it has been 3 months now and nothing worked. Few times my phone did boot properly with IMEI and other details but after few days same error( Don't remember what I did which fixed earlier)
Also, I did visit the repair shop but they didn't find any motherboard or IC damage whatsoever.
Experts/Mods need your help.

Bootloop Problem

Yesterday I tried from my flash to go back to a previous version of MIUI and from that moment the phone stays on the POCO logo restarting and emitting a vibration, I tried to install the official rom for twrp and it remains the same, then I have returned to my flash with another version of miui and it's still the same, I don't know what to do
I leave you the link so you can see the twrp record in a text file
