I just upgraded the firmware to the latest build (oupgrade -force) , but opkg update fails since then.
This is what I get:

Remove wrong Signature file.

Plus, I cannot connect to the console anymore

@Boken-Lin the https://github.com/OnionIoT/Python-OLED script requires installing cffi which is not possible to do on openWRT, any ideas how to overcome this problem?
