Oook so now ive got this vzw 4510l flashed to vzw that i was using and now im having issue with connecting on the activation screen its keeps connecting/disconnecting over n over and saying sim not insterted randomly all started happening after i upgrade the firmware with a duu files.. Is the 4g lte sims sold on ebay the ones I need for a replacement sim or does it have to be specifically a 4g lte 4510l sim card.. thanks

I was always told to use a new never used SIM. Im using a flashed 4510L right now.
What activation screen do you mean? Did you try to reboot your computer and the mifi. THen input mifi password again manually
