there isn't even a stable 4.0 rom, let alone 4.2, so that would be a themed 2.3.6 rom then?

he didn't, it's themed 2.3.6
Kies / nandroid backup / samsung help centre
@mjz2cool is correct..
This device simply dont have any CM / ICS Rom...
Then how did he flashed JB Rom ?
--
By the way use kies to return back to stock...
---
Didn't you people made stock nandroid backup ??
strange !!
Use Odin
First I would like to tell you that there is no Jellybean for your device........There is a port of Cyanogen Mod 9 which is unstable..........
So the ROM which you installed may be a themed Jellybean i.e. In settings it may show 4.1/2/3.x and look like JB but its not real JB .........
You might have installed ROMS like JellyBlast etc.....
So if you want to revert to stock then you might have to flash the stock firmware using Odin.........
But in your case your PC cant detect your phone so you have to restore CWM backup in case you had it......
Otherwise you might install other Custom Rom and see if the problem persist .......
In case your PC can detect your device then you can flash stock using Odin if you want to............
If helped please hit Thanks

Hi ! Ok first you have to update your phone to 4.3 android that is tge last official built from sammy or you will face efs problem (no network) then root and install cwm (U suggest you philz 's one ) and download and install back to noot rom
Warning : there is no official 4.4 for s3 but arter port touchwiz 4.4.4 for our device with back to noot, that is a heavily debloated rom (lot of sammy app have been deleted for stabilty)
And now there's no 5.0 for s3 let's hope note 2 get it so dev can port it
Cheers !

@yogeshbatra: upgrading firmware to 4.3 as @HawKeyes_XDA said.
Then I recommend a Samsung-based 4.3-ROM, if you like Touchwiz-features or run RAM-intensive games, or otherwise AOKP-5.0. Imho 4.4-ports don't offer obvious advantage (but bugs) and waiting on 5.0-ports is pretty dreaming, because even slim AOKP-ROMs are struggling with 1GB RAM.
