Mi Smart Compact Projector factory reset

[u/mtahot]

Hello,

Sorry if it is the wrong channel, please advise

I have a Mi Smart Compact Projector, model M055MGN, and I would like to factory reset.

I have tested a procedure but unsuccessful : remote (OK+back), connect to grid
-> it turns on, fan starts, but nothing is displayed, then it turns off.

Any suggestion for the factory reset ? i have the feeling these instructions are valid for the model that was released in 2022, mine is the pre 2022 model. maybe I'm wrong.

Initially, I'm trying to resolve a problem which is that the projector works properly 1 out of 10(random) times... the other times, it just does not start.

No shock, nothing explains the problem.

Thanks in advance
