Thanks you @Wayneo,
Here is a working link for the videos: https://imgur.com/a/5tMuZNt
I've checked the sequence, it's the default one: FFFFF
During the monitor, the button indicator is: Down
When I press the fire button on the mod, it says Down, Fire
I guess it means the down button is constantly firing ? That would explains why the menu is looping and why I can't unlock the device
Is there a quick fix to do in the software before opening the mod ?
I guess the suspect is the wheel on top, e-juice often get there
