I ended up buying Nolimitdronz and at first I tried that one but it didnt allow me to either get rid of either the Altitude limit or the NFZ restrictions , but the 102 version did allow for both of them to be altered,the reason this all started was because of the firmware upgrade the did to my bird made a place that I"ve been flying at for years a NFZ, it works great , I flew there this morning , I noticed after a flight that one battery was tough coming out and after getting it ouit I noticed it was swollen a little, I checked it during the charging process and the swellings down but I"ll check it after the next flight and if it swells up again I'll scrap it and buy another one.....
