Can you post the Miflash log?
Miflash/log folder, Txt file + or -25kb.
Use spoiler.

If you have a Chinese version (K40s)and you have locked the bootloader on a rom other than Chinese, it comes from that.

I'm not the OP.
With the bootloader unlock you can flash any version of stock rom, EEA, Global, etc, and lock the bootloader.
Except if you have a K40S or you have to let the bootloader unlock.

If you need to leave Fastboot mode, just press and keep a combination of the Power button + the Volume Down for about 10 seconds.

have you any Expierience with Fastboot and the Terminal? than i have Read that your Device has A/B Partitions!!! That means SLOT A has now your Flashed Firmware & SLOT B has the older StockROM!!! Normaly when a Partition is Broken it changes the SLOT Automaticly!!!! with Terminal and fastboot can you Interact with the Device via PC!!!! so that you can use this commands to become the Information witch SLOT is Active, and SET one of the Booth Partitions!!!!

Show Activ SLOT
fastboot getvar current-slot

SET a SLOT
fastboot set_active b
or
fastboot set_active a

Show Activ SLOT
fastboot getvar current-slot

Reboot the Device
fastboot reboot


I have write a simple script that Downloads the Firmware,Extract it,copy Files 4 Flash,and Start Flash!!!
you Found that in my Onlinestorage Here >> Xiaomi_POCCO_F4_Firmware_Flash
Only Download it and extract it!!!

You cannot use Mi Flash with a locked bootloader.

not working...error:FAILED (remote: Erase is not allowed in Lock State)

 

[System23]

OK, original Tools and Firmware cannot Flash in locked BL!! than you can Flash in Recovery or in EDL Mode!! you stuck at Fastboot Mode so you cant Flash via Recovery!!! or you use fastboot in Terminal and test the following commands!!!

Boot Recovery via fastboot
fastboot boot xxx/Images/recovery.img

or
Reboot Recovery
fastboot reboot recovery

or
Flash Boot/Recovery
fastboot flash boot xxx/Images/boot.img
fastboot flash recovery xxx/Images/recovery.img
fastboot reboot

when this not working you can use EDL-Mode!!!

Than you can Flash it with QPST or QFiL Tool from Qualcomm!!! but i must look when i at home if the fastboot Firmware includes all needed Files!!! rawprogrammer0.xml patch0.xml firehosexxxx.mbn

Stop posting non-solutions.
Miflash unusable with the bootloader locked. (Yet noted on the OP).
Regarding your last post, the command syntax is wrong and it will not change anything.

For EDL mode, you don't know, it is not necessary to open the phone to enter EDL mode and anyway, it will not have permission to flash.

QPST or QFiL Tool from Qualcomm may work but not on this device (too recent) and Sahara is a very sensitive program and requires some experience to avoid errors such as:
ERROR: function: sahara_rx_data:277 Unable to read packet header. Only read 0 bytes.
ERROR: function: sahara_main:983 Sahara protocol error
ERROR: function: main:320 Uploading Image using Sahara protocol failed
Download Fail:Sahara Fail:QSaharaServer Fail process fail.

give me more Input, iam intressted to read more!!!

This is not the subject of the thread. (do some research).
If it is impossible to enter recovery or fastboot mode and if it is not a HW problem, the phone is in EDL Mode.
It will not appear on the PC unless you install the Qualcomm drivers and will be detected by Miflash (in Fastboot mode, no need to log in) on a com port (login mandatory), but you will not have permission to flash (requires a special account).
This permission is not needed on very old devices.
Until the OP has answered my questions, I could not provide him with a possible solution.
