I just bought an iPhone 17 from T-Mobile and ran into some issues while setting it up. I accidentally logged into the wrong Apple account, and after trying to switch to the right one, the phone locked me out and required a passcode. I forgot the passcode I just created, and after several attempts, my account got disabled.
Realizing I hadn't really done anything on the phone yet, I decided to restore it. I tried using my older Windows laptop with iTunes and the Apple Devices app, but the restore failed due to slowness. I've also attempted to use two family members' Windows laptops with both iTunes and Apple Devices.
The process gets to the "Verifying iPhone restore with Apple" step and then I encounter Error 9 every time. Now the phone only boots into recovery mode, and I've checked all cables and ports. I've made sure to have the latest software for iTunes and Apple Devices. Does anyone know what might be causing this issue or how I can get around it?

Error 9 is often related to USB connectivity issues. You might want to check your USB cable and try using a different port or a high-quality cable. Apple has some guidelines on this too if you want to look them up.
Definitely give another computer a try if you haven't already. And just a heads up, if you're using a Windows PC, make sure to try both Apple Devices and iTunes for the restore.
Sometimes, this error can happen if there's a problem with the boot firmware. I faced this issue when downgrading from a beta version. I used the iMazing app to fix it, but it's a paid option. If it comes to that, maybe check out the app as a last resort!
