Using CDMA workshop, I have unlocked this vx5600 and changed the spc to '000000'. CDMA ws also reports the field service code and one time key subsidy lock to both be '000000'. So I have no idea what spc LGNPST is looking for when I try to get into nv edit. One note is that I am using vx5500 dll in LGNPST (I can't find LGNPST_GENERICMODEL_VER_3_0_17_0.DLL). Thanks for any help.
