U MUST use files made especially for CONVERTED 2500-2700...they have not been created and released yet to fix this present ECM..but should be released in a few hours
they are in 2 formats...PUFF or B75...U can use either, based upon which boot file U use...
www.dssrookie.com is the best site for those files and info
here's the link to that specific area there.. http://www.dssrookie.com/forums/center-b-font-color-f8f8ff-size-1-fta-conversion -area-font-b-center/
Ennino--not sure if you are asking how you know if the receiver is puff or b75 but if so, then you know by looking at system in the menu or booting the receiver. If it scolls Puff, then it's a puff. If you see numbers then it's b75.
However, if you are asking how to tell the difference between the two bins, it's in the labeling. You will be able to tell which is which.
