Restoring teach pendant with original backup

Can someone advice proper steps to restore with .dt file ? Initially disabled dcs in order to jog robot but after the reboot asked me for mastering . Decided to do a back up and found out when I clicked all of the above that it did not send over the features that were initially on robot and now have srvo 056 servo 006 servo 037 alarms . I also noticed the start up program is not the same as the original when I did the back up using this method . I soon discovered that image file was mot available on roboguide . So in short what is the suggested method or approach to restore the original set up ? All I have is all the original tp programs , .dt file and approximately 397 other files that I attempted to load into the teach pendant . Thanks
