I recently backed up my 4S to my Mac Book Pro with goal of resetting phone to reset & fix a problem with no sound from Music. In the process I was prompted to install latest versions for both my phone and my computer.When I have gone to restart my phone I get a greeting scree showing "Hello". I click on that and am then asked to activate my phone-with the original ID used to set up the phone. It can only be 1 of 2 ID's both of which I have tried with just about every password I have ever used. Have tried changing passwords. To no avail Cannot open phone. HELP!!
