Error trying to flash evil portal

[ugnius0303]

I bought this board from ali express

which comes pre flashed with wifi marauder and then i tried to use esp flasher to get evil portal on it and now nothing works i get error messages, so do i need to fully delete the marauder off of the board and start from scratch?

Did you use the correct files for the esp32?

Marauder also has its own Evil Portal, so there's no need to flash a standalone Evil Portal FW.

Hope it isn't too late but this one works fine with the official devboard sources, and there are youtube videos by devs on how to make this thing work. (https://www.youtube.com/watch?v=Mnv05jEKFvA)
Also as @0xchocolate said, Marauder comes with Evil portal so there is no need to flash another evil portal (during which you probably will flash another marauder if you blindly follow)
