Are you talking about the "[How To] Reset your phone in order to return to Verizon(Updated 12/11/2012)" and "[GUIDE] Debrick your bricked SCH-I535! [BOOTLOADER/HARDBRICK]" stickies? Those are the only ones I see in this section. I currently haven't done anything to my phone so, those don't really apply to me yet. I did however browse through them. I saw the mention of Odin, a ROM flashing tool. And rooting would probably give you access to the system settings required to flash these ROMs onto your phone. This is all I can make out at the moment.
