Based God had been backstage before his Saturday evening set at the Mountain View, CA fest when he says rapper A Boogie wit da Hoodie and his posse jumped him.
Lil B claims during the fight, someone -- not A Boogie -- skedaddled with his bag which had laptops, a camera, and a ton of cash. TMZ's Lil B sources say in all $45k worth of stuff was taken.
Lil B had to cancel his set since he didn't have the gear necessary to perform.
Cops tell TMZ they don't have a suspect.
