iPhone 11 Pro
My iPhone 11 Pro suddenly died on me today at around 20% battery life, When I turned it back on the apple logo would flash and it would get stuck repeating that. After plugging it into the computer and force restarting it, I was unable to update it because of bad firmware. Then I tried restoring it and it is unable to be restored because of an unknown reason..... What do I do next?
iPhone 11 Pro Max, iOS 13
