My wife's iphone 10 won't start anymore. Already did some troubleshooting kungfu like hard restart, charging it for hours, nothing happens. Warranty already expired last April so can't avail for replacement.

Went to Powermac support center hoping there's still a way to have it fixed but was told that they can't fix it and its best to just avail for a full replacement minus the junk cost of the dead iphone.

I'm now musing on the idea of looking for a reputable but unauthorized iphone repair shop. Any recommendations? TIA
