I never successfully booted any modified NAND even though my connections may have not been the prettiest but they were electrically sound. Everything was working fine using my original unflashed nand with the JTAG and flasher wires in place.

Once I received my usb flasher I proceeded to wire it up and make three successful identical dumps. I then injected my keyvault and config into xbr and flashed it to the nand. When I booted it up I got error 79 and then everything after that has been three flashing red lights with no video output (with variations to some degree, ex. 4 solid green lights then 3 red flashing red lights).

Ive tried everything I can think of and nothing seems to work. Ive replaced the jumper for j2d2.4-7 with a 330 ohm resistor (from a thread I saw on here), and then replaced it with a switching diode, Ive resoldered and cleaned up my connections multiple times, Dumped images multiple times and made sure it was valid, remade the hacked images, and probably more things.

Ive been screwing around with this thing for a week now and havent gotten anything other than 3 flashing red lights and no video output. I fear that my falcon is dead....

don't give up man, I've been trying to jtag my xbox too and it took me forever to finally get it, but once you get it its way worth it!
pretty sure its not dead, but just check your connections again, you could've splashed solder somewhere and shorted something out, iirc E79 is when your jtag connections are a bit off, I got that when I was using diodes on my xenon, then went with the 3x 330 ohms and it worked great.
Also when flashing, what I had to do was put on a blank xbreboot, then patch ONLY my kv.bin to my xbox directly (nandpro lpt: -w16 kv.bin 1 1). After fiddling around with my connections and writes I finally got it after a long time, then after I got it once, I was able to do my 2nd within a couple hours(mostly dumping/writing).
Basically just keep at it man, I highly doubt its dead

Thanks for the pep talk (IMG:style_emoticons/default/biggrin.gif) I meant to post pictures of my connections but I forgot to, Ill add them now.

I think someone... Needs to practice their soldering...

[thwack]

You've got shorts (and lots of em).

Looks like between pad 4 and 6 (J1D2), and all over FT1U2 - @FT1U2 look slike you've also got a broken trace.

Heat up your soldering iron, add flux to the areas of shorts on the mobo, and gently brush your soldering iron ove the excess solder. It should stick to the iron and get rid of a lot of the shorts. Be careful though.

I cleaned the flux off of the areas with 91% rubbing alcohol and I did find a stray line of solder between the nand and the southbridge, but fixing all of that didnt change the state of my problem at all (IMG:style_emoticons/default/sad.gif)

Heres new pics:

Did I miss anything?

Edit: Can someone show me where the grounding pad is on FT1U2 because apparently thats my main problem and I dont see it.

Upon closer inspection of the pictures I see where stuff is being grounded out, hopefully that will fix my problems.

[brando56894]

Here's the most recent pics I've taken and as far as I can see nothing is shorted by messy solder, I will attempt to fix the FT1U2 trace with window defogger trace paint. In the mean time I scraped another trace before it (just the wire this time, didnt touch the grounding pad!) and soldered the wire to it. Its connected but not extremely secure since there isn't a lot to solder to. There was a little bit of solder bridging the trace for 5 and pin 6 on the rf panel connector which I cleaned up also. But even after all this I still get the same red lights.

The capacitor C1D7 needs re-connecting - dunno what it does or if it's the cause of the problem though.

Also what's the secondary error code of the 360?

[brando56894]

Re-connect it? It looks connected to me, can you show me wheres its disconnected?

If by secondary error code, you mean whats displayed on the tv, I've got nothing. I haven't had video output since the first time I flashed the nand a week ago.

I think its officially dead now, I was trying to connect where I thought it was loose on C1D7 and the capacitor melted and disappeared.

Well it doesn't look connected on the left side of the cap in that picture. And your secondary error code is the code you get when you hold down sync and press eject whilst the 360's rlod'ing.

I think you should probably find someone to do the soldering for you (no offence), the 360's saveable, but if you're having difficulty with it it's a good idea (IMG:style_emoticons/default/smile.gif)

Ive been getting ripped apart for my soldering over on xboxhacker for the past few days so what you said it nothing compared to what ive gotten over there (IMG:style_emoticons/default/laugh.gif)

I think I'm finally going to give up trying to do it myself, one of the guys I work with said he's pretty good at soldering but cant help me for about another week or two since its exam time here. Any idea where I could get a capacitor like the one I melted (C1D7)?
