WiFi greyed out after Updating to iOS 13.1.2

Hi everyone,

I updated my iPhone 8 Plus to iOS 13.1.2 a few weeks ago and since then my WiFi button has been greyed out. I’ve reset the network settings multiple times, restarted/rebooted while in airplane mode, and reset all settings multiple times. I’ve also tried taking out my SIM card. I tried to update iOS through iTunes but received an error saying that the firmware is not compatible. Checked my security settings and firewall settings on my MacBook Air, and made sure my iTunes was updated to the latest version. Tried to restore my backup & update through iTunes, but received the same error. So now I’m stuck on 13.1.2 because I can’t update OTA or through iTunes. I’m trying to avoid resetting my phone to factory settings because 1. A lot of people with the same issue have said that it hasn’t helped and 2. If it doesn’t work, then I’m afraid if I try to restore my phone’s backup through iTunes it will give me the same error thus, leaving my phone completely blank without my contacts, photos, etc.

Anyone else having this problem? I wish I never updated to iOS 13 because it’s been nothing but problems smh. Any help would be appreciated!
