CUSTOM RECOVERY:So most of you guys who've seen the previous post on "How to root the international GS3" need to have a custom recovery as it offers more options than the stock recovery and you can use it to flash software to your device instead of using ODIN downloader, so basically installing custom recovery is the same as rooting your phone [Check previous post] the only difference is the file you're going to flash isn't the CF-Auto Root but it's going to be the custom recovery itself.
There are lots of custom recoveries out there, but this is a very good one called Clock work Mod (CWM) which has a pretty good list within the interface, the recommended one is 184.108.40.206 version as most ROMs are compatible with it. DOWNLOAD CWM 220.127.116.11 BY CLICKING HERE.
What CWM offers:
1. install zip from SD-card
a. choose zip from sd card

the download link is here.
The download process as I mentioned earlier is pretty much the same as rooting your phone-check previous post- but you would rather flash the file I've linked in here.
