SORRY FOR MY BAD ENGLISH
 
If all we know is that you tried many things the chances are that the suggestions you'll get are things you've already tried. Telling us what you've tried would reduce the risk of that.

I don't know this device, and Verizon have a reputation for locking everything up very tightly, but in general my first question to anyone wanting to do this would be "can you unlock the bootloader"? And the second would be "is there a custom recovery built for this device model and version?" (if there isn't you really do not want to try to install one built for a different device). If the answer to both is "yes" then you should be OK. If not, you'll need someone who knows this device to advise you.

I am also assuming that somebody has built Lineage for this device - if not then the rest is irrelevant.
