SKR 2 will not flash firmware

it won't load the firmware from the sd no matter what (formatted to fat32, 4kb cluster, tried multiple sd card sizes (2, 4, 64gb), tried changing file name to various things, tried with USB power and 24v power supply, unplugged everything from it, tried multiple compiles and ensured its for my 429 version, etc). What else can I try? The way I'm checking if the flash was successful is by seeing if firmware.bin changes to firmware.cur on the SD, which it does not.

That sounds like a lemon :/ You have file extensions visible right?

yes, as always problem solved! I just found the 8gb card that came with my ender 3 and it worked I have no idea why though. It's formatted the same as all the other cards I tried.
