Hi, I'm new here and need help.
I've installed openwrt 19.07.2 to my Acher C5 v4 router (using tftp tp_recovery.bin from 192.168.0.66 method).
It doesn't work as expected (cannot save any setting) so I want to go back to the original fw.
Unfortunately neither the tftp recovery method with reset button nor the uart tftp recovery method work for me.
I have uart console acces, but none of the back_to_stock_firmware methode works.
With UART:
