Hello, I am currently trying to JTAG my Halo3 Edition 360. It one of the older model....and I will go ahead and clarify.

Yes - Kernel version is able to be exploited
Yes - I do know how to solder and it is soldered correctly

This is a jist of the errors I am getting...I seen another thread that was posted in the past and copied theirs, but it is the exact same problem....invalid errors.

I have tried removing the resistors and it doesn't help. I have tried all the BIOS settings and nothing seems to be working. I fully understand there is something wrong, and I would appreciate input from anyone who could please help. Anything that could be wrong or that people have encountered BESIDES soldering? I am using an LPT cable ... (Yes I know...barbaric at best...waiting on my USB SPI flasher to come in any day now.) Please help...thank you!
