1: copy e3downgrader fix BD beta.bin into e3 upgrader disk
2: insert E3 card reader into ps3 right usb port (near BD driver)
3: jailbreak ps3 like normal way, after few second, console will off autoly.
4: remove E3 card reader from ps3, and reset console, it will enter factory service mode.
what diffirence with old e3dowgrader firmware ?
after jailbreak ps3 with old downgrader firmware, it will enter ps3 menu, you need reset console to enter factory service mode.
with new firmware, it will switch off(no need enter ps3 menu)
