Unstuck my phone
I have an old iPhone 8 I was trying to get running so I can give it away to a friend who needs a phone but it would not boot. I tried putting it into recovery and DFU but iTunes would fail the update with an error. I started researching online and found out about reiboot so I gave it a try. It specifically has a function to fix error 9 and reinstall the firmware on the phone. There's a ton more features like being able to kick the phone in and out of recovery which is great if you have damaged buttons on your phone.
