Fivio Foreign‘s year has been a total wash, seeing he’s been jailed since January on a weapons charge … there could be a light at the end of the tunnel for the “City of Gods” rapper!!!

The New Jersey PIO tells TMZ Hip Hop that Fivio pled guilty to terroristic threats — threat to commit a crime of violence in the 3rd degree.

Fivio had been facing 4 other charges, including unlawful possession of a weapon and aggravated assault, but Fivio’s attorney Adam Lustberg tells us those counts are expected to be dismissed in exchange for his guilty plea.

We broke the story … Edgewater Police arrested FF on New Year’s Day after a woman accused him of pulling a gun on her when she asked him for a car jump.

Lustberg tells us he hopes Fivio will end up with probation when sentenced in August … especially since he’s already been in jail since the arrest early this year.
