How do you unlock the bootloader?

view story

http://forums.androidcentral.com – Have my device rooted and running a rooted rom. Would like to unlock my bootloader so I can run a couple roms I saw on xda developers including an updated rom by beans but they need to have the bootloader unblocked. The instrucions and video on xda seem too complicated. Is there a simpler way or should I wait for one to come? I dont know about adb mode which it seems you need to know to unlock it their way. Any thoughts? Sent from my SCH-I605 using Tapatalk 2 (HowTos)
