I found a workaround to restore the bootloader behaviour.
In case of power surge, the keyboard would move to bootloading mode, if no firmware uploading happens to it then it will verify, load the firmware as usual. I have tested with my ethernet cable with 100% backlight on, it restores the keyboard behaviour after power surge (see lights off & back on shortly - and it looks kinda cool as well!), no need to reboot or flashing the firmware now. 
Here is the release.
