W8 刷內核 MSM7227.7z解鎖 手機死機(原廠修理原因) 內看

If the date code on the sticker reads 11W29, or any later date (11W30, 11W31, 11W32, 11W33, ...), DO NOT attempt to unlock the boot loader.
以下引用來自 xdadeveloper 英文論壇 說明11W29以後為何解鎖會變磚
These phones ship with a revamped chipset configuration having the security hole the boot loader unlock uses effectively closed. This means that upon unlocking the boot loader your phone will end up as a hard brick - and you will have NO means to revive the phone yourselves. You either have to send it off to Sony for repair (recommended solution) or find a phone repair shop being able to resurrect shot devices!
