I was trying to flash openwrt 21 clean firmware on my ar300m but not sure what went wrong, after the update its booting only on NOR firmware.
I tried uboot method but uboot is not allowing me to flash .img files. I get the errors file is either too large or you are trying to update ART which is not allowed (attached). My switch is on left side only (near reset button)
I flashed the latest uboot .bin file which i got from https://github.com/gl-inet/uboot-for-qca95xx/blob/master/bin/uboot-gl-ar300m-20201224-md5-d06d53166f9eb2cb321c15c3ec0a87e0.bin it got flashed. Afterwards I again tried to flash the ubi img files but again same error as attached.
Can anybody guide how can I debrick my router to get back to nand firmware.
