I tried the update last night but I ended up getting an error I think it was E78 or E79 when I started up my xbox? I can't remember because I panicked when it happened and took my nand dump, renamed it updflash.bin and restored it through xell reloaded and that fixed me up. I'm not sure where I went wrong though. I followed everything but I think maybe it didn't choose the right Jtag SMC hack? I didn't do my JTag so I wasn't sure what wiring it was, I let the bottom right of the program choose it for me. I have the two wires inside with a jumper all on top of the board and one of the wires goes to the board on the front next to the ring of light. I have a picture of my xell cpu key if you need to see it and my current kernal version is 2.0.14699.0 and dash version (from fsd) is 2.2 rev692. Not sure you needed to know that but thought it all might help. I was trying to update to the most current version. Also it says my Motherboard is Falcon/Opus and it automatically selected the normal SMC Hack. Thanks for any help you can provide. I'd love to master this updating.
I have a picture of the xebuild screen before building if anyone can help me from seeing it. I also have a picture of what I believe to be my jtag wiring.
