I need help repairing my OS puleassse!
 

LG Optimus Extreme (LG L40G)

I screwed up. About two weeks ago I rooted my phone and I uninstalled the default browser which was also a system app, and now no internet browser is working for me. Firefox doesn't work; Internet Explorer doesn't work, etc. But apps that take you straight to a webpage do work 7 out of 10 times. Apps such as: YouTube, Play Store, Gmail, etc. This is driving me nuts. Rebooting the phone doesn't work because I deleted a system app and system maps don't come back. Please help.

If you know of any way to fix this please, for the love of ***, tell me. Do I need to download any internet drivers or something or would it be possible to completely wipe the whole OS and install a fresh one? /grovels
