No i didnt cut beyond the light green as that would cut into another trace. What i did was i did those v-cuts which would cut off continuity between orange and light blue lines, but the green line would still have continuity. So what i did to cut off the green line was to make 2 separate deep cuts, 1 on the left of the v cuts and another 1 to the right of it, they were straight cuts.
For the iprep, i use something called iPrep_0.12.2.1 and made my usb drive bootable. So i would boot off the usb drive during windows bootup so it would run in DOS. Then i typed LIT ********(*which stands for what you would like to name your drive which will create a folder on the usb drive)Then i proceed by following the directions which appear afterwards. BUT before it proceeded to detect the drives, i put the pogo pins on point A and B, pressed any key to cont, and it started detecting the drives, however, i had to do this part many many times before i could properly detect it. Afterwards i typed "R" for read and before i execute it i removed from point A and typed Y to proceed and it read properly, make sure your datasum isnt 0000 or else it was a bad read. O yea and i use a VT6421 PCI card to read it and make sure u disable all your drives so it makes finding your 360 drive much easier as there should be only 1 to select from the list, hope this helps
