Method 2 will always work since it flashes over the entire ROM. This may or may not preclude future updates (I don't know; I have updates disabled and am running VRALG1 build with VRALHE modem--I don't plan to rebuild until JB is officially released.)
Whatever you try, feel free to post results so we can see, from experience, how different combinations work.
I am new to the galaxy s3 and took the 4.1.1 update, only to realise: 1) the update was available a while ago and 2) i would lose root. Not very bright, I know. But I have only had this phone for three days. Would method 2 work with the JB update? That is, using ODIN to flash a stock rom. Thanks.
