Kimax U25CWF - Serial Connection?

I've installed openwrt on my kimax U25CWF, and for that i've used "15.03.ramips-mt7620-u25cwf-squashfs-sysupgrade.bin" and was working ok, for some time, but now I've messed up the network connections and can't get access to the device, because it only has wifi connection. Does anyone now how to connect with serial to this device? I need to reset the config.

Tks

Did you try the reset button? Press and hold it a long time during boot.

A simular device has serial connection without pins. See https://wikidevi.com/wiki/Kimax_U25AWF. You can solder yourselves a serial cable.

Hi Rein, thk for the tip, but the reset buton does not work, I belive it's a firmware thing. :frowning:

I'll try the solder part...

Is it possible to confirm if the 2 gold small dots that i maked in the photo are the tx and rx?
