Question [Q] PC's won't recognize my S3

I have flashed a stock rom on my S3 with mobile odin, because any pc wouldn't recongnize my s3. but that didn't solved the problem it made it worst. Now my s3 says it isn't on stock and I have as a standard app mobile odin and Super User but my phone isnt rooted.

I installed drivers kies ect. tried different pc's and cables. tried rooting my phone with framaroot but it didnt work. search whole xda and google but could found anything.

Also I'm on 4.3. If there is a way to root my phone i would be happy that pc won't recognize my phone isnt the worst thing so.. anybody?
