Now the phone won't turn on, no signs of like at all.
Is it completely dead?
Doesn't sound good unfortunately. For what it's worth I long-pressed the power button during a recovery freeze and mine survived, although that could be totally un-related.
As far as diagnosis goes, what have you tried? Click the link in my signature and go to the section for 'no download mode'? and follow the steps there. Hopefully you can boot into DL mode somehow, then you should be good.
Does it get hot around the camera while charging? If yes, coupled with the lack of life signs, then unfortunately that's probably a motherboard replacement sorry.
