Can I flash any IJEOS bin to go back to stock?

As the tittle states, I am trying to flash my car back to stock using the bimmerboost app and I want to know if it matters what IJEOS file I use.

From the download section i see that there are:

- IJEOS_09_bmw_e90_n54_10of2008_PM73_6AT_sport_premi um
- IJE0S Stage 0

My car is a 6MT, so i dont know if the AT files make a differene or not?

Someone stole my cobb app while still being married to my car. My clutch started slipping, so I used a local friends Cobb Ap to flash to stock. I ran into issues at first, but eventually the flash worked and i retuned back to stock power, only without cruise control functionality.

I want to flash over a stock file in the hopes that it will restore my cruise control. Cobb advised that i should have a back up on my computer, wich i belive are the folowing files:

BMW_MSD81_0044CC0IJE0S_1964_enc.rom
BMW_MSD81_0044CC0IJE0S_1964_enc.rom_sum

BMW_BASE.xml
BMW_MSD81_0044CC0IJE0S.xml

BMW_MSD81_0044CC0IJE0S.dat
BMW_MSD81_0044CC0IJE0S.dat3

From what i read it seems the (.rom) file is what i need, but i have no idea on how to convert it over to a (.bin) file.

Any help or suggestion is appreciated!! Thank you!
