I don't use DFS, never have, probably never will.

I'm not exactly sure what the issue could be, but something you've done isn't right.

Use QPST, open up connection with it to the Incognito and look at the tabs regarding the PPP Config for Rm, Um, and AN, as well as the M.IP tabs.

Make sure you match the settings from the Incognito to the new phone.

Use QPST to write the Profile 0 Username, HA, and AAA that is from the Incognito.
Use QPST to write the Profile 1 Username (w/e@boostmobile.sprintpcs.net), the HA (secret), and the AAA (6 digit readable code from the incognito).

If you don't know what the actual AAA is, you need to read NV Items 465-466, and 1192-1194 from the Incognito.

Make sure you DISABLE roaming on the "new phone" and if the settings have the option to select CDMA, GSM, LTE, set it to CDMA only.

I'm sure you've done all this, but switching between multiple programs trying to get 3G working on one phone isn't solving much. Most all of the programs do the same thing, and for 3G, you must have the information correctly wrote to the "new phone".

If all possible, try to get QPST going with both the Incognito and the "new phone" loaded (in QPST) and once you do that we can schedule a teamviewer session.
