CONTOUR LOCKED. Hold Back and turn knob to unlock

Hello,

I’ve read some posts on the forum, and the only solution they suggest is a factory reset.

Yesterday, I encountered the error for the first time, and it kept restarting without working. I did a factory reset, and it worked, but the error keeps appearing every time I turn it on and then disappears. I’m afraid that one day it will stop working completely.

Is there a permanent solution? Thank you so much!
