Samsung Galaxy Sol (Cricket)

Hey everyone I was hoping for a little help on this 1. I just purchased the Samsung Galaxy Sol (SM- J321AZ) AND wanted to make a back up and possibly flash a custom Rom on this device if at all possible. I have the Galaxy Tab E 8.0 (SM- T377P) and third to do the same thing without making a backup and not it's pretty much a paper weight as every time I download a .tar file it won't flash and none of the major websites have a factory or custom Rom so that I can use it again. (If anyone can help on that as well that would be SUPER AWESOM). Anyways, I don't wanna make the same mistake with this device as the other so I figured I would ask for some help. I need to network I lock the Sol phone as I'm a T- Mobile user but this was the only phone they had at the store that was not a flip phone. Hope someone out there can help.

Thanks in advance.
