Yep, hid settings while in settings and now I can’t get back to settings. Holding down ‘S’ is bringing up: exit, shut down, Custom shut down…and Reboot. No more settings, ugh, help, thanks
Just about to reinstall osmc anyway, due to kodi not finding my smb://windows user/shared folder. More on that later. Simple problem for now, thanks
An easy quick fix would be to SSH in and reset the gui
systemctl stop mediacenter
mv .kodi/userdata/guisettings.xml .kodi/userdata/guisettings.xml.save
systemctl start mediacenter
That will give you Kodi with the default gui.
To reset the skin itself (and thus the hidden settings option) you would either edit or delete the .kodi/userdata/addon_data/skin.[name of your skin]/settings.xml or just take the easy path and via SSH type in…
kodi-send --action=Skin.ResetSettings
Worked like Putty 
What do you mean by this (i’m not familiar with this phrase)? Was your issue rectified?
I used the ssh client Putty to run the code on the kodi and everything worked out as needed. Emoji was suppose to be a wink.
