DEVICE_COMPAT_VERSION := 2.0
DEVICE_COMPAT_MESSAGE := DTB was added to sysupgrade. Image format is different. \
To use sysupgrade You need to change firmware partition in bootargs to "49m@0xf00000(firmware)" and saveenv. \
After that, You can use "sysupgrade -F".

It is required to flash the entire sd-card again and manually copy config.
