I accidentally locked one side of my ring to read-only. Any way to undo that?

Sorry if this is the wrong place to post.
I was playing around with an nfc app and accidentally locked it :C Is there anything I can do?

Try Trigger, I'm pretty sure it has that function...it can also erase the tag completely also.

I have a sneaking suspicion that once locked to read only they can't be unlocked again.
I'll be interested to hear if I'm wrong!
