Unable to flash h7 plus firmware

When attempting to de-brick the H7plus cam-
if I select h7plus as the board then the camera never finishes its self check after reloading firmware (led stays green instead of flashing blue despite waiting for 20min and leaving in an external SD card) If I hit ‘ok’ the camera goes back into the white LED flashing error

if I select just regular h7 as the board, I am able to complete the flash however I run into out of frame buffer stack memory

Try removing the SD and erasing the internal flash fs (there’s a checkbox when uploading the firmware) also you must never use a different board firmware for yours.

removing the sd card worked. thanks
