I have been starting to have issues with my Spark Connection since a few days ago. It would cut off my LTE and put it in 3G mode barely connecting. I tried troubleshooting before I called Sprint. I upgraded PRL and Profile but still no dice. When I called Sprint, I spent over an hour on the phone trying to find an answer before they transferred me to Technical Support. Tech support told me to turn the phone off for a minute and then after turning it back on, upgrade the profile. I ended up doing that along with the PRL and it fixed it until today I started having issues again. I tried doing the same thing but am not having any luck, I have attempted this over 10x and still no dice, it barely connects to 3G now and I can't even talk to customer service because they are closed. I am using optimus 4.2.2 rom. Does anyone have any clue if this is my handset or Sprint's side?
