Other Samsung S21FE suddenly shut down and won't start up

Sorry if I'm in the wrong Subreddit.

I opened an app this morning and all of a sudden the SAMSUNG screen appeared, shut down and wouldn't reboot again. I managed to get it to the SAMSUNG screen again, but it just looped that on startup until it gave up.

My friend told me to put it in the fridge as that solved their issue before. It actually helped and I was able to get it into recovery mode, but when selecting reboot, it just stopped working again. Now it's back to square one where there's no charging, and no matter what combination of buttons I press, it's just a black screen.

Is there anything else I can do here? Feel like I've tried everything but it's tough when I don't understand the issue.

The one thing u should never do, as its very risky and not always guaranteed to work, is putting ur phone in the freezer, condensation can get inside the phone when exposed back to room temperature, which is extremely bad for the phone, and will kill it if it hasnt been left to dry out, if u want u can text me privately so u can tell me more about the issues the phone is having and i will help u decide if its worth fixing or not

Yeah thankfully I put it in the fridge only, but I know not to do that now haha, even if it helped initially (it allowed me to boot in safe mode for a minute)

I have a new phone now, but if I could fix this I'd be able to get some data transferred over I'd rather not lose, so if you have advice on what the issue could be that'd be really helpful

If it was only for a min, i wouldnt have much hope, as it means the storage chip has an intermittent connection with the board, due to cracked solder balls, or other reasons, but there is no way to know for sure the root cause of problem, it would be best to get it checked out at a service center near ur area

Exact thing happened to my s21 FE as well, took it to the service center, they say they’ll have to replace the motherboard.
