goto team xecuter's website and look at the step by step diagrams. make sure you are looking at the guide for 1.6 xbox's i know you are gonna come back here and tell me that there is no x2.6 pictures even though the x3 and x2.6 are almost identical so here is a install guide... http://www.yoxbox.com/tut/xecuter2-6v1-6/ once you have the chip installed and the xbox boots to Flashbios, follow this guide for flashing your bios...it is very important you flash according to the guide. http://forums.xbox-scene.com/index.php?showtopic=351619
triple check your solder points, and look for solder splashes(if you soldered the chip in) once the chip is installed correctly the xbox will boot to Flashbios
