Default sm-n900w8 kitkat csc change

I noticed that when i flashed the mex telcel kitkat leak the first go around that everyuthing was fine....i went and lost my stock 442 backup and thought i would go reflash everything cause there were things i wanted plus i wanted that nice clean backup... i went and flashed the files again over xnote 9.o and lo and behold telcel showed up. so i went and dialed the csc changer.....*#273imei# and it comes up with preconfig menu with TCE at the top and then a big black screen and then next and continue. I went to change it to vtr and there is no way to change the csc code.. I get the typing icon but no input menu....any suggestions???
