How to Root the Verizon Samsung Galaxy S III Running Android 4.1.2

Thanks for the thorough guide. I only wonder how to go back to stock 4.1.2 directly without to flash to 4.1.1 and then take the OTA to 4.1.2?
I get FAILED on step 15 =(

This looks very helpful. Going to do it today. Only question is, though: Once this is finished, will my phone be reset back to stock or will all files and configs still be present and unchanged until I put a ROM on it.
worked great!!! thank you!!!
i got failed on step 15 lost
I failed in Step 20. The 1:[COM4] does not show up in Odin. Any suggestions?
Whoopse, figured it out
Thanks so much for sharing this info!
I am not seeing the supersu bootloader file while in recovery. I did what you said and copied the file to phone memory not the sd card.
Any suggestions?
