iPhone 8 Plus stuck on restore mode and force restart is not working
I have an iphone 8 plus that suddenly went to restore mode. I have been reading a lot on how to force restart. But it's not working. even the DFU mode is not working. When I plug in the iPhone to my macbook it says that I need to do software update. I do software update and restore so it downloads the latest firmware but when it's about to get finished a message pops up and says
I have tried "Update and restore" for about 10 times and my iphone can't get pass the restore mode
need help.
