I installed ls-kk-v3.0-2014-03-10 kitkat 4.4.2 firmware on my phone and used a notes lite app to keep down some important information. Today, the phone's battery died Nd upon recharging it and turning it on, it was as if the firmware was just installed. I had to set up the home screen again, however my old wallpaper was still intact although out of focus, my bookmarks from the chrome browser were gone, contact names gone, apps still there.
However, the notes in the notes lite app were gone. How can I find my old notes? Why was everything reset like this anyways?
