I think the best bet to completely circumvent this whole 3G-SVDO/4G issue is to do both tweaks. That's what I did and have perfectly stable 3G. Both the 4636 (i.e. Phone Info turn off 4G) and the 778 (Enable RevA and disable eHRPD). This makes it act exactly like all the other 3G/EVDO phones on VZW.Getiing 1X all day in fringe areas(savannah, bluffton-sc). Read this forum post. Tried the ##78 adjustment. It showed 3g for a minute.....then nothing. No 3g, no 1x....no data whatsoever. Went back into Settings and set it back and now just gettinv 1x again. Anyone else.
