The title says it all. Nothing good can come of flashing with Odin except returning to stock. Stick with CWM or TWRP flashable zip files. If you disregard this message you will end up with a locked device, or even worse, a hard bricked device. Please use Odin as a factory restore tool only. I'm concerned that after unlock using our methods that people will flash the wrong thing and cause problems in the future.
The unlock method we have provided
is not a standard Bootloader Unlock. It is an IROM unlock. This means you can quite literally flash anything to your device without any sort of signature checks. It is important that you stay safe and try to stay away from Odin unless absolutely necessary.
