If you can do one for a 50x50 matrix the result can be added to

I've just upgraded my old iPhone 4S to a new 6 Plus.
It's still small enough to fit in my pocket, and the
extra screen real estate makes running J nicer.
Of course the new phone comes with the current version
of iOS: 8.4. Thinking it would be the easiest way to
move files in and out of J, I purchased iExplorer as
the easiest way to move files in and out of J.
Well! It seems that as of 8.4 (or maybe even 8.3) it
is not possible to see the files of applications that
have not received permission from Apple for this. (It
is possible to see the files in the "backups" folder,
but I don't think it would be easy to import data this
way.)
iExplorer says on their website that the app developers
should contact Apple to have the restriction on their
app lifted, implying that this would be granted (?).
So has anyone faced this issue with an iPhone 6 running
8.4? What is the best way to move files into J? I am a
bit reluctant to jailbreak this new phone (though I did
that with my old 4S).
Thanks for any help,
Patrick
