I want to remove the Record Type applied to a Custom Object. There will be no record types at all.
I cannot remove one of the record types because its set to the default for several profiles (in fact all profiles). Therefore it seems like I have to manually enter each profile and delete it. Joy.
However, for Chatter type profiles I don't have the option to enter "Object Settings". So I can't remove it it from these profiles. Which means I can't remove the Record Types attribute at all.
Any ideas how to get around this?
Ideally I'd like a page, like the one I was offered when I created the record type, that lists all profiles and has a picklist for each row ('default on' or something).
The only "solution" I found was this: https://success.salesforce.com/answers?id=90630000000h2pXAAQ which seems like its out of date now. I can't navigate to a setup/ui/profilerecordtypeedit.jsp page as described in that link.
