getting the front and back covers off is less than half the procedure. now you have to get at the pin that that holds the battery cover in place. next the battery cover has a metal contact strip with 2 more screws. but behind that there is a release button and a very small spring that has to be transfered to the new battery cover. then the pin that holds cover needs to put in place. after cleaning the screens. then put on the covers front and back. carefull to use the correct screws in hte right holes. suggest doing work over a white piece of paper. having a well lite area. using a magnofy glass is helpful. als having a magnet and tweezers availble. 1st time be prepared to take well over an hour.
