I have a Galaxy S2 running on ICS. It is not rooted.
Recently it keeps crashing. No app will start with the exception of lock screen and the notification curtain. My menu button does not work so during my research on this problem the "download GO Launcher and set as default > clear data" solution will not work. I want to keep this post as short as possible so here are some links on my first problem:
(These two posters fixed their problems due to their menu buttons being able to function).
Looks like my only fix is to do a factory reset (though if anyone has a few suggestions, please post them!).
Unfortunately not being able to access any apps means I cannot do back ups. I want to restore my phone to the pre-crash state as much as possible. I have a valuable memo on the "Memo" app that comes with TouchWiz. Can this be done?
EDIT: Forgot to mention that it's best not to void my warranty by flashing or rooting. My S2 has some screen burn ins that I need to get fixed and they'll be checking.
