Sup guys, have encountered some unknown feature, while exploring functions of my flipper, turned on Stealth Mode and now it’s stuck in wallpaper and not functioning anymore, somebody help.
The stealth mode only turn off sound and vibration. Do you mean dummy mode?
All you need to know should be described in this document: Controls - Flipper Zero - Documentation
If you’ve set a PIN and forgot it, I am afraid you’ll need a full factory reset.
