Q: "Console powers on, but I get a black screen."
A: Well, there are many reasons here again. First, wait some time (~1
  minute), and see if you get a RROD. If you do, the VM code failed to
  handshake with the SMC (error code XXXX), which usually means that it
  crashed, and the SMC watchdog triggered until it retried too often.
  Did you use the proper 2BL/4BL image for your machine type? Did you use a
  recent enough SMC version? Since the VM code took more and more time
  (from roughly a half second in 1888 to several seconds in 1920), the SMC
  code was modified to time out later. Be sure to use a known-good SMC
  version, if possible, based on the version which was installed before.
  If you don't get a RROD, please try checking your POST code. You can do
  this via CPU jtag, or by measuring the 8 POST pins.

  Post code 6C:
  The exploit failed, somehow.

最新:

搞错了,8 pin 不是JTAG 的 TDO

是FT6U1---FT6U8

具体方法在07年的Timing Attack有详细介绍.
