I have what is probably a very dumb question, but I will ask nevertheless as I do not want to screw anything up rooting my S3 The last thing I rooted and flashed was my D2 and that was trivial. I was reading the thread on rooting the S3 ([GUIDE] Root for Jelly Bean OTA ***UPDATED*** - xda-developers ) and it asks you to download ODIN to you PC. It then asks you to boot your phone into ODIN mode. Yet they never mention downloading it to your phone in the first place...is there a version I am supposed to DL for my phone or is this something made by Samsung that is already there? Again, excuse my ignorance regarding ODIN...I had never heard of it until I started searching around to root my new S3.
