No wireless interface after upgrade Mi AC2100

Hello
i am new to OpenWrt
i have installed breed on my xiaomi mi ac2100 (black round router)
after this i installed openwrt for breed from here:

https://4pda.to/forum/index.php?s=&showtopic=973368&view=findpost&p=108376183

and all works like it should
but i saw on official openwrt site that latest version of openwrt for ac2100 is 21.02.3 here:

https://firmware-selector.openwrt.org/?version=21.02.3&target=ramips%2Fmt7621&id=xiaomi_mi-router-ac2100

i have downloaded the sysupgrade bin file and updated via luci but after the update the wireless interface is missing and there is no wireless option
i tried other sysupgrade file and it says generic and not mediatek like in the version before the upgrade
i would appriciate any help
thank you

Use the device specific image, but make sure to reset the settings during flash.
