Getting to NBTevo_V

[frownmonkey]

I have a Mini F60 and my goal is to get to NBTevo version V. Flashing using psdzdata 4.25.40 (latest as of now) gives me only version U (NBTevo_U19384I). I know version V on Minis is a thing because that's the one that supports fullscreen Carplay unlock over cable.

I poked around in the binary data files for the HU_NBT module and there are definitely bin files in the distribution with "V" version numbers:

• "NBTevo_V20153J" from btld_00001ffd.bin.007_008_010
  
• "NBTevo_V20153I" from btld_00001ffd.bin.007_020_010
  

The version that got installed is from a "007_007_008" version data file. 

Since I know next to nothing about how all this works, can someone help me understand how the flash/calculation process selects one data file version over another? Is that stored in the car or in the psdzdata distribution? And, more importantly, is there a way to encourage esys to select a newer version for my car?

Thanks!
