I had some more devices that need the 2.4GHz and fail to connect to this firmware (Garmin watch, Google Chromecast), so I need to downgrade to 23.5.3.
What would be the correct way to do that?
The instructions I initially used fail:
dd if=factory.bin bs=1M count=4 | mtd write - kernel
Could not open mtd device: kernel
Can't open device for writing!
My AX6s has the new uboot:
grep ^U-Boot /dev/mtd2
U-Boot
U-Boot console
U-Boot
U-Boot BUG at %s:%d!
U-Boot 2014.04-rc1 (May 20 2022 - 10:19:21)
Luci warns me that the sysupgrade.bin file is incompatible:
The device is supported, but this image is incompatible for sysupgrade based on the image version (2.0->1.0). Invalid image type. Image check failed.
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
What would be the correct way to do the downgrade to 23.5.3?
