my home button isn't working, and my phone is acting all funky

[smoham2]

I rooted my phone some time ago and never really got to tinkering with the new features it brings to the table. Today I decided to take advantage of root and delete the bloatware from my phone, so I download the app NoBloat Free and deleted some system apps. Of course, me being the fool that I am, I deleted something important, and now my home button isn't working, and my phone is acting all funky. I can't access the page where apps are, but I can access settings by swiping down from the top. Also, the home button works to access task manager when I hold it. I tried factory resetting it, but still the same problem. Can someone please help?

And if you are willing to help, can you be as specific as possible, because I'm not too savvy when it comes to this stuff. I read somewhere flashing would help fix it, but I don't know where to start (and I'm severely epileptic, so was a little scared).

All jokes aside, I would appreciate some help.

Thanks in advance.

I can't get into details but you can probably recover by first off downloading a software app for windows called Kies. For my s4 it's kies 3. It has a firmware downloading and recovery option. However if I had to do this I would download the stock firmware for your exact phone model. ..this information is widely available on a forum called xda forums. The file size you can expect most likely over 1.5 gb in one zip file. That file is flashed. A windows app called Odin. And most likely version 3.07..would be used to flash the original firmware. Expect a big file some reading on the specific file name you need for your model. A couple windows small app installs to load the stock firmware via the oem usb cable you charge with and plug into the pc where file is stored. ...time. ..and patience. Good luck man
