Hello,
here is another tips, how to take flashing job such phone by mxkey.
Here is boot check output by UFSxHWK.
Just example using UFS. 
And this is the BUS Check by using mobileEx current version. 
Try to fix the flash loader if you had problem like this. This also fix DCT4 issue about "BootLoader not responding, mostly RAM problem !" 
Nay...nay..nay.. This phone is not supported for flashing on F-Bus interface. 
As told by mobileEx, that current interface is not supported, so we must use Nokia USB ROM.
And all be done without any problem. 
Code:

Phone Type:
SW Version:
Imei plain: -
Language Pack:

Total time to process is 4 min 55.312 s
USB Pooling failed, phone not found !
Just ignore the final error message, that is not a problem.
You can use F-Bus for any Service Operation.
It is supported. Reset, Format, write PM, etc.
