EDIT: YOU want to try, you try, else DO not flood the thread with useless comments about how safe is this or what not. If you are afraid the chinese will take your close to useless info and kidnap you, can't help you with that.
I unlocked my BL with this file. Currently waiting for people to make 3rd party roms for it.
Attached link to my gdrive.
Download and install. It will prompt you if you wish to unlock BL. It will not wipe ur internal. You can proceed with ODIN to flash TWRP.
TWRP is available too.
