4g problems on Samsung galaxy s3 from boost

[Unregistered]

My 4g worked just fine until my phone died last night. When I plugged it in and turned it on, it wouldn't work. I can use 3g, but just barely. Is there any way to fix this? I've tried everything from switching connection types to turning it on and off.

I am not sure if you have something like this, but is there an updates section in Settings? If so, there should be a few choices. Try update PRL and profile.
