I can not read the screenshots.? They would need to be at a higher resolution or larger.
The file you listed could be either a v5 or a v234 file.? Verify that you have the files from the uBITXV234 folder, not the uBITXV5 folder.? They both have the same file names in them.
The blurry USB Calibration seems to be in the general range 11997000 range, so you should hear the background noise you would use to set the BFO.? If the background noise disappears in the BFO setting, it would indicate that the wrong file has been loaded.
Do you hear the "hiss" change when you disconnect the antenna when not trying to set the BFO?? If not, then use a screwdriver to touch the test points on the main board to see where you start to get the hiss or hum.? The test points in order are 2, 1, 13, 14, 16, 17, 20, and 21.? 20 and 21 are at audio frequency, so you should pick up a 50 or 60 Hz AC hum.? The others would be the normal no-signal hiss on a radio.? You are looking for a change in the speaker or earphone sound.
Here is the GitHub link to the KD9CEC 1.2 programs:
Download the zip file and unzip it.? That should produce two folders.? Be sure to use the uBITXV234 folder.
I would also caution that the v4 has known spurious signal issues.? The fixes can be found on this site:

The relay replacement solved the harmonic issues for both of my v4 uBitx.? I have not done the other fix as I do not operate above 20 meters with these uBitx.
