[Q] Please ............ help - Galaxy S III Q&A, Help & Troubleshooting

Hello,
1- sorry for my English
2- I have got galaxy GT - I9300 , I was able to connect to ( Samsung Kies ) and ( Odin3 )
3- I un-rooted the phone and upgraded it to Jellybean 4.2.2
4- Now I can't connect to both of ( Samsung Kies ) or ( Odin3 )
5- I installed different drives and they all failed
6- I still can see my phone connected to PC as portable media player ? it appears in the device manager ( GT - I9300 )
7- I need to know how to come back to the original firmware ( step by step )
8- am I supposed to uninstall kies and driver before starting ?
9- Finally , Does ( Samsung_Galaxy_S3_ToolKit_v7.0 ) concerned with original firmware or custom roms ?
thanks

There is no other way than odin or mobil odin , if you are on a custom rom it maybe rooted already so try installing mobile odin and flash with it.
Link for mobile odin : http://forum.xda-developers.com/showthread.php?t=1347899
EDIT : I forgot to add try uninstalling Kies and samsung USB drivers then install this drivers.rar it should work .

I usually find stock roms use more battery as custom roms sometimes have a lot of bloatware removed which would run in the background and consume ram, cpu time and could wake the device from deep sleep.
Ps: Fygaroo post that helped you would look even better by pressing thanks on it.
