Soulja Boy woke up to some heartbreaking news … some heartless saps broke into his beloved SODMG flagship store in L.A., and TMZ Hip Hop has the ghastly aftermath — of the $25K worth of damages!!!

See our footage from the scene for yourself … disrespectful thieves went straight through the front door of Soulja’s store — without a key, leaving mounds of broken glass on the ground on Melrose.

The store’s boarded up for the day … and adding insult to injury, there’s already a fresh coat of graffiti on the entrance door.

It also appears bolt-cutters were used to loosen the locks, causing some red paint to chip off onto the steel … either that or the cops are gonna have an easy case to crack once the DNA samples return!!!

A source close to the situation tells us thieves made away with exclusive Soulja Boy merch, including shirts, hoodies, hats, and one-of-a-kind Bearbricks.

Other swindled items included Soulja Boy’s memorabilia custom leather jacket, and even a PlayStation.

We’re told the team has since hired a 24-hour patrol service to watch the store from here on out.
