Prompt [Q] I9300 Newbie ROM Help

Hi

Just managed to get a dead S3 into download mode with a GPG Boot cable , as a iPhone user (please dont boo me , I'm jailbroken at least) I have very little understanding of the Android ROM system , I'm unable to find matching files and have to wait about 10 hours to download every one.

If someone could tell me the right files I need to flash this phone back into stock rom I'd be very grateful.

Its a I9300 UK Vodafone with the stock OS it came with , I'm assuming 4.04 ?

I'm not sure which version of ODIN I need , nor either the .tar all in one or .pit / csc / phone / modem files.

I dont mind waiting a week to download these files so long as they're correct.

If you could tell me this it'd be much appreciated and If I can work out how I'll tip you in some xda-developers forum way.

Many Thanks
Keir Lawson
