I wanted to delete my wallpaper on my android 7 TV-box, but when I used some file explorer for this purpose, it deleted some important file(s) by mistake in /data/system/users/0 and I could not restore them. I could not install any data recovery from Google Play either.

Now, I cannot use my keyboard properly or download apps from Google Play and many other personal settings are not as they were before.

How can I restore system files /data/system/users/0 just like the way it was?

Should I use factory reset at last?

  • Yes you should factory reset. /data/system/users/0 contains - other than wallpapers - all of your Settings configuration, apps permissions and components details, app widgets, login account, fingerprint data etc. I don't think you can recover all of that, but try making all settings if it works. – Irfan Latif Apr 12 at 23:02
  • thanks for the answer. before that, I need to know how I can make a backup of my android on an external SD and then restore it from there, to avoid any surprise. – Leo Sam Apr 13 at 8:33
  • That's a different question and lengthy to answer. I think you will find answer in backup tag. If not, ask a new question. – Irfan Latif Apr 13 at 8:43
