First of all I want to thank @zogu without him, this guide would not be possible, This guide is for phones with Hard Brick, where the bootloader is destroyed and there are no tools that recognize the phone as odin
When you connect phones without a bootloader, Windows detects them as exynos9820 in device manager.
All of this is accomplished by trial / error method
I repaired my g975f and I have U3 and U8 files only for this model, but I will try to explain how to prepare files for any other model.
We have to use the same bootloader version that was previously on the phone, or if you're not sure, use the latest sboot.bin.
Plug in the phone and press and hold the power button.
Windows will detect the exynos9820 device, install the driver:
click manually,
com and lpt ports,
select the Driver Exynos USB Mode folder
Now we have to copy
WinDNWApi.dll
in:
C: \ Program Files \ Samsung \ Exynos USB Driver \ Drivers
There probably isn't this folder, just create it and copy the files.
Now we have to create the boot files.
Using lz4 1.9.2 we can unzip the sboot.bin.lz4 to sboot.bin and then be able to edit it, everything is explained in a guide inside the file
Download the last sboot.bin that was on your device
Now you have to extract the partitions from this file
In some hex editor, create 4 files and extract from sboot.bin
0x3000 is BL1 name> bl1
0x3000 ... 0x17000 is epbl
0x17000 ... 0x68000 is BL2
0x7e000 ... 0x7eb000 + 0x190000 = 0x1fe000 sboot
Dram_training do not need to be cut, it is not used in flashing
0x244000 ... 0x1BD000 is el3mon dram

Launch multiuploader.exe

Plug in the phone and press and hold the power button.
Search and find script.cfg
click start and the phone will go into odin mode.
Start odin and flash the firmware (in case of having split the stock rom sboot) or Combination (in case of having split the combination sboot)
the z-zip tool must be downloaded

Binary editor - Multidownload flash tool with files for sm-g975f u8 x32, x64,
