Thanks. I'm still on NE3 modem, have you noticed improvements in the latest modem, signal wise? Will it work with 4.4.2 (I'm assuming it will but you never know)?Here is the latest OH1 GS4 I337M modem with non-hlos, do not flash zip! extract and flash modem only. Tested and working great on Samsung GS4 Rogers phone, should work with all Canadian carriers

I wish there was a thread or more discussions based on modem firmware performances, I know you just gotta try it but I always like to have some input from others from their experience.
