iOS 14 Public Beta glitched out phone completely

Hello people!
I downloaded the beta on my 7 Plus as soon as it was possible, and since then, I had many problems:
  • Microphone not working, therefore no Siri or Voice Messages

  • Safari doesn't work anymore, it just says that there were "too many requests"

  • Flashlight stopped working just today

  • Charging sometimes just stops, saying "This accessory may not be working" (rough translation)

Is there anything I can do? I already tried using a backup from before I installed the beta, but it still doesn't work and it's still on iOS 14...

To go back to iOS 13, you would need to restore your device to iOS 13, then restore from the backup you created while it had iOS 13 installed. Google something like "revert from iOS 14 beta to iOS 13" for instructions.

Same issue. iPhone won't restore through the recovery mode.

It always restarts and remains on iOS 14. Does anyone has the fix?

Device: iPhone 7 Plus.
