@albertifx “I took the phone to an “unofficial” support and they told me the problem seems to be the whole motherboard and they don’t get replacement parts”, yes this sounds right. All of those issues seem to lead to a bad motherboard. I would at least have somebody take a look at the board and see if it can be repaired. You will of course need someone that knows about board repair and microsoldering to look at this. You can always post some really good pictures (front and back) of your motherboard with your QUESTION. That way we can see what you see and maybe identify any issues. For now make sure that you backup all your information, pictures etc., since you stand to lose all of those. A new motherboard will be your only other option.
