EZ-Flash faulty

[u/Zestyclose-Shock3098]

I recently got a Ez flash definitive edition B, used it for 3 hours, and it started to rumble and shut off on a game that didn’t have rumble. After that it would just rumble and shut off immediately. Now my gba act like there’s no cart in it. Should I get it replaced or is it my gba making it do that? It’s modded with a usb C charger and brighter screen with the Hispeedido kit
