Can you please remind me how to do this? Without the extra features I'm with you that this early version isn't worth the beta battery drain. Is it just a DFU restore or do you have to download the ipsw separately and then ALT restore. Its been a while since I rolled back.
Sure thing, yes you have to DFU restore to go back to a previous version. I hope you have a backup or are ok with setting up as new. I went back to 18.1 so I had to download the rc ipsw.
Plug the phone into the computer and do volume up, volume down and then hold the power button as if for a hard restart until you see the recovery screen.
The do the option + restore option and select the ipsw for 18.1 or just click restore and it will download latest release software automatically.
Hope it helps!
