Just created my own ms_.nbf file (ext rom) and I can give instructions on how to make one. Even though the instructions are in how to make your own custom rom. Removed it from the ftp folder cos Iguidance is not free software, and doesnt have a trial, also some of the software on there is not useful anymore. Always glad to help, if anyone needs any info or help.
This extended rom includes the following software as well as no sprint junk.
capture screen utility
check notifications
gsp pocket magic
iNav Iguidance (not useful if you dont have the software cos you need the maps)
mp4 audio codec (so you can listen to mp4 audio now)
20225 prl cab (still have to click on ppst.exe after the ppc is up and soft reset)
unhide ext rom cab
contact cab (allows you to select/deselect all contacts)
Everything shows up in remove programs, so you can delete what you dont want)
If you want any of these programs (apart from Iguidance
) PM me and I will upload it or make it avaialable.
