my smart plug Kankun KK-SP3 not working anymore
by mistake I write 0 > /sbin/reboot
now KK-SP3 just turn blue light without any respond there is no wifi and I can`t reset by clicking button for 5 sec
If the device has its wireless interface disabled, i.e. unreachable, you will have to pry open the case and solder cables to the serial headers on the pcb to fix it.......
but those links not working anymore!
please any body can guide me to fix my KK-SP3
Thank you so much
Basically, you pull the contents from the chip, replace the space your firmware (I suppose vanilla OpenWrt?) occupies with a sysupgrade image, not a factory image, using dd. Then you write the modified dump back.
