No need to worry guys, happened to me, no matter the phone, iOS 14.x public release will most likely brick xs max and Xr devices, took mine to geek squad and basically the same night that my phone updated my device got super hot and fried the CPU(did a circuit test with a Genius Bar), apple claims it isn’t their fault, 199 through asurion insurance or 599 from apple, or upgrade, no defect or recall so enjoy :) (I did insurance because iPhone 12’s are on backorder) but that’s also not apples fault ;)
