i dont think a deleted app can be recovered...still you can find suitable app for your model and push it into system...tell me your model...may be ill help you out...you can always download some other browser like chrome and others from he play store...should work like a charm...
The page you are referring to needs a base recovery. I am not sure what to put in there.
