Lost homescreen and icons when leaving any app

[fabgav]

Hi all, bit of a newbie so please bare with.

i rooted and installed System App Safe Remover and got rid of a few bits of crap, all was until i deleted live wall papers and g+ products

Now when ever i press home button nothing happens, i can reboot and get a homescreen but all icons are missing.
AQlso if i use return button it will not exit any app.

i can access recent apps with double tap of home button and i have tried restoring from the safe app removal program but had no luck.

I am happy to reset the phone all data is backed up but will this restore the problem or will it wipe all apps/data but still have system apks missing?

I did no s-off my device.
had SU installed

any ideas?

thanks
