The evidence is that up to this point, all iOS 18.X IPSWs have been bricking devices if updating with Apple Devices. I posted yesterday asking if this has been fixed for or if it’s still the current behavior for the iOS 18.1 RC, I am keeping up with the thread and so far nobody has commented saying they’ve tried it and had a result one way or the other. So why would I not assume that it’s still failing the update and bricking iPhones if nobody has shown evidence to the contrary? I definitely don’t want to take the risk to find out for myself; yet again, after trying it on 3 devices the last time around.
If it bricks someone’s iPhone, that could be the device someone uses to post here. They wouldn’t even be able to tell us.
Did you update with Apple Devices? What was the result?
