The IPSW for 236 is still available online if you wanted to go back. I doubt it would help your issue tho. Probably a re-install of the current one would do just as good.For me the v2 (not OTA) is borked. First one was fine, i did the mistake and upgraded, my very own fault.
I just went to an Apple Store, asked them if they can install the v1, because my Mac is a few thousand miles away- of course they can't do that![]()
