Unable to set my Volumio in Test mode

After a factory reset i’m not able to set my volumio in test mode and upgrade to dev. versions
On the IpAdress/dev page I have tried clicking Test True button but it makes no change in behavior

Any “magic” command or file I can edit to change the state? :question:

same question

how to get the test mode state
how to manually change it

as my father always said , “patience son patience!”

The Volumio was in Test mode ! , but was there some kind of halt on updating to 2.330 ?

To 2.336 now works fine :wink:
