Relative died. Another relative trying to make use of their iPad (6th Generation A1893) gave it to me (the family "tech guru") because it wants a passcode and he never wrote them down. They don't care about keeping any content, they just would rather not throw it away. I plugged it into my computer (running Catalina). The iPad would not appear in Apple Music (1.0.6), or iTunes (10.7, I maintain it because it has depreciated features I like), or in the Finder.
There is nothing indicating it is locked by the Find-My feature. After some research, I put the iPad into Recovery mode. It appeared in the Finder. I ran the Restore option. After some time, the process was done and the iPad rebooted. Unfortunately, it still wanted a passcode. I tried a random passcode and it now says "iPad is Disabled. Connect to iTunes" (which, as noted, it does not appear in iTunes).
After more research (https://discussions.apple.com/thread/6146220), I tried running Update first. Unfortunately, after going through the process, I received the error "The iPad iPad could not be restored. An unknown error occurred (2015)." I've done more looking, and all paths seemed to lead to https://support.apple.com/en-us/118106. However, I've already done all of these steps.
So what do I do if I get the 2015 error while following the instructions for the 2015 error?
Additionally, if this IS locked by Find-My, would they have to go through his iCloud account to unlock it since it no longer offers passcode entry? (If so, why does it insist I connect it to iTunes which offers no such entry?)
