I got this issue, kinda, I've gotten my Galaxy S3 back from a warranty claim, because I one of the unlucky bunch of the "sudden death" glitch and I can't update from 4.0.4 on my phone not from the OTA anyway, been trying to get it going from Kies and well that didn't work either, because it says the phone can'\t be updated, so the last thing is Odin...thing is I can't find the correct jelly update I've come across several of them and most are for UK, and when I did find mine the PDA and CSC don't match so I'm at loss here, generally I can find my way around these sort of things sadly I just want to be safe and not brick this time xD
I'll just leave this phone info here...
the obvious model is I9300, the international version
baseband version: I9300UBL6
any help would really be appreciated
