help with Coolpad Catalyst

I used kingroot and accidentally deleted a wrong file. Then I restored and now I can't get that file back.. my messaging app and browser just crash on their own. I tried doing a master reset but it didn't do anything. Maybe you guys can help if you have the stock rom or a cyanogen mod or any custom rom to at least get a working phone? Thanks a lot. I'm a newbie..
