Unable to Access Admin Panel GL-MT300N-V2

I have a new GL-MT300N-V2 and tried to upload a previous version of the firmware. Ever since I cannot access the admin panel. I’ve tried to reset the unit and the Uboot process but still no luck. I’ve connected to the unit via wifi and hardwire and when I go to the default gateway address I either get a 500 error message or it says Initializing the file system with a spinning circle but I never get to the login screen.

I’d appreciate any assistance.

Which version did you flash? Can you give a detailed link?

Can you clear browser cache and try?
