I need help using DFU mode to do a clean reinstall of iOS 13.3.1 on my iPhone 8. Apple Accessibility refused to help me because the woman said that their staff are not trained to help with DFU mode and that I would be jailbreaking my device if I attempted it. I asked to speak to someone in tier 2, and she said she was tier 2 and that she was a supervisor. What a joke! can anyone on here give me instructions on how to use DFU mode? I am running Mojave on a MacBook Pro and iOS 13.3.1 on an iPhone 8. due to severe battery draining issues since I updated my phone, I need to completely wipe out my phone and start over from scratch. any help would be greatly appreciated. Thanks.
