Hello, this is my first time commenting here.
I encountered a big problem with my POCO F3 earlier today, and I think it bricked. I just use it like any normal phone for almost 2 years now and have been using xiaomi.eu rom since last year.
But today I hit a wall that may be the end of the line, it won't turn on, won't charge, doesn't do anything just a black screen, even the recovery and fastboot shortcuts don't work. My latest update is 23.3.20 and my thinking says that maybe a bug in the software caused this problem. Now I'm panicking because I use it everyday and this is crucial as a student as all of my files for school is stored there, currently I don't really know what to do to fix this issue.
This is the first time that it happened, it was very smooth for the last year I've been using the custom rom but unfortunately it doesn't work anymore atm.
If you could help me solve this without losing/wiping data, I would really really appreciate it.
