哪敢童鞋成功了？H大，你试验了吗？

还是XDK用用吧！用自制太麻烦了

lz的步骤好像跟英文原版顺序上有些不一致阿
短接方式我个人建议将其焊上，测试一下能够正确读取了再焊开，当然一直焊着是什么状况偶没有测试。
具体流程为：
1，焊接44-47.
2，给主板供电，只插电源，不开机！
3，读取NAND信息。
4，焊开短接的4个脚，完成。

shorted pins 44-47 with a flat head screw driver (gash I know).
sequence of events,
I disconnected power brick,
shorted pins,
connected power brick,
un-shorted pins (removed screwdriver)
ran NandPro 2.0b. It now shows correct flashconfig again hooray!!

最近开始动手改造

先留个备份，以后没准能用到

虽然希望这一次成功，用不到最好，呵呵

读取NAND有什么用呢？

This is what you nand looks like, you'll notice in the top left hand corner a dimple on the chip that is signifying pin 1.
This is a shortened chip with leg/pin numbers.
the objective is to prevent the SMC from retrieving its instruction code/firmware, by shorting and confusing the data lines.
I shorted pins 44-47 with a flat head screw driver (gash I know).

Pins 44-47 are I/O pins don't carry any voltage so to speak so chances or blowing something is less but not impossible so only do this if you are completely stuck and the alternative is to remove the chip bench program it.
Re-flashed with correct xell image booted linux flashed xbr all is fine now phew!!

原来解BAN过硬盘，现在刷脉冲自制就读不出NAND了用这个方法试试看
