Okay I'm pretty sure what happened is that the 1ST nand was accidentally overwritten by a bad nand. So I don't have a good nand on my 360 or Computer. Is this 360 totally done? Please tell me there is a way to get a good nand back.
Always make backups! I am not sure so don't do this unless someone agrees with me Nandpro LPT: -E16 0x000000

K, I was typing the command wrong with a b instead of a d after nandpro. Anyway now I get this no matter what setting I use for the parallel port.

EPP, ECP, AT, or PS/2......278,378,3hbc don't matter same thing.
Help me please, this is it not finding the port right? Not an issue with wiring yet I hope cause it all looks good.

ok well i successfully wrote xbr to my xenon, and it booted up just fine, with 8955 and no e79 or rrod. but sometimes, the xbox goes weird and wont let me do things, for example if i hit the xbox button on the controller, then go over to profile, the profile will pop up, and then go away. it wont let me edit my bio and stuff. also, when i boot up xexloader, it wont let me create a folder on the root. it pops up, and then goes away. another thing is when i exit to the dashboard from XeXloader. i get the 1 red ring and e71. i am starting to think this is a bad flash. should i re-flash, and maybe without my rawconfig.bin injected this time?

Not exploitable.

Why does Xbins detected by lots of av`s
The nature of the program is detected as a trojan. Its safe though.

Yes you could have a patched CB. This is how to know.

If you console has a manufacture date of 6-1-2009 or later its patched. Anything before that is safe and not patched.

You don't need it to jtag but I think it allows you to downgrade your kernel.

I just spent over $100 on an exploitable xbox and I am really really nervous I might mess it up.

I say that because the tutorial for modding the xenon is different here:

http://www.se7ensins.com/forums/modding-tutorials/207681-tut-noob-proof-installing-jtag-xexon.html

In that tutorial, on the actual jtag part, the connections are different than the one in this thread.

I would use the tutorial in this thread, because I have tried it and it works perfectly. Except when your computer craps out on you when it is dumping your nand <_<.

Okay, I still have E79 error and I have been Resoldering for a day with testing. Should I try the other 330 Ohm Resistor connection?
