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.

DFU mode
Hello,
First off, put your iphone 8 in recovery mode by holding the power and volume down buttons. You need to have your phone connected to your mac before you do that. After puting your phone in recovery mode, itunes will come up notifying you that you have your device in recovery mode. Select restore. Then download and install, in the resolting dilog box. Then agree to the terms. This will take time, as iOS downloads in this process. After the download completes, your phone restarts. Upon that finishing, then you either set it up as new, or restore from a backup, either on your mac, or from icloud.
Hope this helps,
Daniel

I have read on here that there is a difference between recovery mode and DFU mode. The Apple rep even told me that there was a difference. could someone please verify?
