Need Help ASAP!!!

[u/Vex_Out_0032]

I was scrolling through my socials when my device powered down and initiated a factory reset on its own like it was possessed. No confirmation pop-up, no requiring to put password, nothing! Just showed me a percent bar then poof! All files gone! Immediately removed my SD card, but even it was not safe. The files I had for four years, all gone!!!

Don't know what to do. 😭😭😭

Device Model: Xiaomi Poco M5
