.. i didn't mean to add the &W in there as well only the &F, just in too 
much of a hurry.

ok conf.factoryResetCmd then.

how about:

if (!atCmd(conf.softResetCmd, AT_OK, conf.resetDelay))
           //report error here
           if (!atCmd(conf.factoryResetCmd, AT_OK, conf.resetDelay) || 
!atCmd(conf.softResetCmd, AT_OK, conf.resetDelay)) {
                   //there's really no coming back from here - crash and burn.
                  return false;
           }
  }
  return atCmd(resetCmds, AT_OK, ms);

...actually, now i think about it, maybe not.

It might be better in this case just to disable the modem soft reset 
command, perhaps something like:
ModemSoftResetCmd: ""

in the modem configuration file(the dtr reset before should be enough).
