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
in
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
You overwrote busybox. Would be easier to extract the flash with an SPI programmer(CH341a e.g.) and replace the contents with a working OpenWrt image.
And stick to one topic please instead of opening multiple.
Thank you Sir
I`ll try flash it as soon as I can Buy CH341A
Sorry about duplicate my post I want delete it but there is no option for delete!
I can flash it with [lede-17.01.7-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin]
flash chip is 25q32fv
or need somethings else
sorry I dont know about this things
You'll need to do some reading, e.g.:
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.
thank you sir I really appreciate your time.
I think I messed up board when I desoldering chip
anyway I read chip and save backup
what next ?
I am a Windows user
how using dd ?
