I was able to solve the problems. I couldn't format MMC from disk management, it kept giving errors. I went in with the MMC install option from armbian-install and formatted it, then canceled it before starting the installation. I formatted the mmc in ext4 format from disk management and started it. Then I installed it to mmc again with armbian install.
I am currently using it by booting from mmc. After installing mmc, when I copied the wifi files to the brcm folder, wifi worked too.
It's working fine now and I'm installing the klipper.
thank you very much for everything
