You could try flashing the update with Odin I don’t have the link handy right now unfortunately you would just download Odin on a windows pc download the Verizon 7.0 firmware connect your phone to the pc in download mode select the proper files for the proper sections and hit start. Look up Odin instructions on google first though. Sorry for lack of punctuation I’m on my spare phone after a screen failure waiting on the parts. Odin is basically a replacement for Ota updates for rooted Samsung devices
