Cannot change Access Rights

I have an NTAG 424 tag and seem to be having a problem changing access rights with TagXplorer.


When experimenting, I changed access rights on all 4 accesses (read, write, R/W, change) to 0F. No matter what I try, I now cannot change any of them back to any other key.


When I try, i get either ERROR 919D or 917E. 


Appreciate any help.
