I just now rooted the phone using the method from this
page using SafeRoot and Disable Knox. I did have to flash the pwnedkernel Modem in CP using ODIN 3.09 from here
. Now that I was rooted, I installed and ran RegionUnlock Away from here
I finally flashed the modem using to originalkernel.tar.md5 in CP using ODIN and flashed.
I now have my SGH-I537 phone rooted and unlocked.
Using the method I mentioned above, if I ever want to UNROOT and leave no trace, what is the correct way to do so?
Would Flashing the stock firmware be enough?
