关于在工厂模式安装self的方法

srw008

研究工厂模式时发现这么个说法
Place this Lv2diag.self in the root of an empty USB flash dongle, and use any method to toggle
Factory Service Mode (FSM) (We're partial to the second release we make today, but you can decide
for yourself).

1. Copy the .self in this release to the root of a USB flash drive.
2. Rename the file to Lv2diag.self.
3. Place the flash drive in the right most USB port.
4. Toggle FSM.
5. Boot PS3
6. During FSM boot, the Lv2diag.self will execute.
我照着把self放进U盘根目录，启动PS3进入工厂模式，然后选择选项1重启，结果就变成正常开机，没出现execute情况
是不是我理解错了还是在工厂模式下有其他启动方法？
