I've rooted my phone a while ago, deleted random apps I didn't really need that were pre installed. But now there's a potential buyer so I'd like to restore to the way it was the second I've brought it from the shop. Default factory reset didn't help as I've deleted games and stuff. So, is there a way to get everything back?
You can use their official update software, it has been called "PC Companion" the last time I used it:
This is mostly for modding, so it won't be that useful to you:
