刷機 & 解鎖 - Android

最近小弟在XDA上找到了這個ROM

http://forum.xda-developers.com/showthread.php?t=1942116

我本身是已經解鎖的Xperia Ray 也順利成功刷機了

但是我有個小問題

文章裡面有寫:

For Locked Bootloaders:
1.Put the rom on SD Card
2.Reboot to recovery
3.Do a factory reset
4.Go to mounts and storage and format system
5.Flash the rom
6.Reboot

For Unlocked Bootloaders:
1.Put the rom on SD Card
2.Reboot recovery
3.Flash the rom
4.Reboot till you see lockscreen
5.Reboot one again to get Wi Fi working

所以是不用解鎖也可以刷機的意思嗎?

小弟不才 煩請大大們指教
