As previously announced the SpiderChip v1.1 met a installation problem. All pogo pins do not touch correctly the motherboard of the Xbox, causing the chip inability to boot.
The screw and the ring delivered with the chip are the main cause of this problem. They are not of the proper size and therefore do not allow a good alignment of the pogo pins.

The pogo pin 'GND' (please refer to the picture),
linked to the problem of the screw, prevents some other pogo pins to fit in correctly. This Pin is a 'security' pogo pin. In fact, it is not used for this Xbox version and it only is here to ensure the compatibility with future versions of Xbox.
One easy and efficient way to install the SpiderChip with perfect result is to remove the bottom of the GND pogo pin (please refer to the picture for more details).
Once this is done, we suggest you to use a 9mm long screw in conjunction with a 2mm thick ring. (If you missed the previous news: Spiderchip has already arranged that all resellers are supplied with bags of correct screws and rings, these will of course be sent to you free of charge. New orders will be sent with the proper screw and ring.)
The installation will be flawless!Source: Spiderchip.com
