Not saving configs

[smartie]

Hi all

I have flash a S20 today which went ok but it won't let me save any device settings
It' says reboot and try again but it still won't save

Any ideas

What version binary did you use? Or did you compile it yourself?
If I remember correctly, these Sonoff's have 1 MB flash.
Not being able to save the settings, may be the result of incorrect settings of flash size.
