JTAG Advise on what to buy for a bricked system.

Greetings,

I am VERY new to this and all that I've tried to figure out is from reading things online. So if something does not make sense I apologize for the mix ups in terms.

I purchased a JTAG'ed Falcon xbox and it was working prior to my attempt to update it with a 3599 update that I built with CoolShrimps JTAG tool with default SMC settings. The update was attempted via a USB on a memory stick.

I did not do the work for JTAG'ing so I was unaware of which "method" was used. In the process of my attempt, I have bricked it. On boot-ups it goes straight to E79 error and nothing else.

Since then I've taken it apart and see now that the seller used the AUD_Clamp method. He has a soldering line to Q2N1 (with a capacitor), a solder line to FT1U2 (with a capacitor) and the last one is a bridge on the DB1F1 (no capacitor). All work was done on the underside of board.

I do not see any soldering done for the "eject" button I've read about.

I've attempted to boot but all I see is an E79 error. Methods I've tried:
* hold eject button
* hold sync and main power button
* USB wired controller attached to back, hold X and power on from controller

All attempts would boot to E79 error with a single blinking red light on the lower right of ROLs.

I was looking to use the NAND-x to try and (hopefully) flash my system back to life.

Can you please advise me if NAND-x kit with the QSB is the best way to go (I have noob soldering skills).

What is the minimalist invasive method I can use, I would like to preserve the original person's work (if at all possible).

I have a flashdmp.bin from the system before I did the update. I have the DVD key, CPU key and the fuse numbers from the person who did the work.

Also, I've had a friend try to boot up to get to XeLL but when he did the eject button method, he got a black screen with words instead of a blue screen as all the tutorials say.

Thank you in advance for your help and for any advice you will provide me.

You will need to write the NAND with new image make sure to enable alt smc option in jtag tool.


I'll add some more info if your a noob at soldering please do not learn to solder on this console. I would send it off to someone in your neck of the woods and have them do the NAND work. NAND x and qsbs are the semi easiest I prefer direct wire. But that's me. Qsbs save lives tin your points then put the qsbs on heat the qsb. And draw the solder up to it. Flux flux flux. If you ruin the points a rebuild will cost ten times the amount then for simple dump and write.

Thank you for the quick reply and I will heed advice. I do not plan on doing the actual soldering, will be asking someone who is an expert, but I will need to know exactly what to do in order to direct him to do the work. I would like to use the QSB because I'd like to have it as "neat" as possible when I put everything back together leaving the QSB's attached.

Any information for noob soldering is greatly appreciated as well. I feel so dumb for not being able to do this myself. It will make for good reading and practice on spare parts I find around to learn on.

If you could answer a few more:
Will the NAND-x kit be sufficient or will I need to buy more parts for my console?

I read somewhere in the guides that NAND is one thing while JTAG is another. Would I need to install both as in the guides or just the JTAG portion (since I have my keys). I am looking at this thread for the install guide:
http://team-xecuter.com/forums/showthread.php?t=54423

If you can you point me to where I can find a tutorial or guide that is similar to my type of hack or is the type of hack irrelevant (except to choose AUD_Clamp in the "SMC Points" section of the JTAG Tool). I was only able to find this thread but it isn't exactly like my setup:
http://team-xecuter.com/forums/showthread.php?t=55189

Can you tell from my attached image if I should be using "AUD_Clamp Only" or the "AUD_Clamp & DVD Tray" in the dropdown of "SMC Points".

I originally followed this thread to do the update:
http://www.team-xecuter.com/forums/showthread.php?t=58111

And I do not know if this is important but I do not know if I originally booted up to XeLL or XBR, because it was a black screen (not blue). I also had a 750GB HD that I used the system to format previously.

You will need to select the aud clamp only as it is not drawing power from the dvd drive you are using an alt point for db1f1. Nand x kit will be all inclusive everything you need. Jtag is the hack and the nand is where your image is stored. Jtagging is the process. If you have all your info keys config stuff like that start fresh and build a freeboot image. All those tutorials are top notch and ones I still follow if I question myself.

use all the qsbs and you will have a pretty motherboard

You don't need to disturb any of the soldering under the board. Just fit the 2 QSBs for the NAND-x (J1D2 and J2B1) which should reduce the amount of work you need to do in order to resolve this.

Thank you.

If you would not mind verifying (and correcting) if this is what I need to do as I am going through the threads:

I am using this as a reference as I do not have my kit yet:
http://team-xecuter.com/nandx_pics/NAND-X_CONTENTS.jpg

* Install #7 (QSB J1D2)
* Install #8 (QSB J2B1)
* Connect #4 (QSB Install Cable) to NAND-x
* Don't bother with any of the JTAG QSB #9, #10 and cable #5 install portion (because I have the AUD_Clamp installed already).
* Connect USB to PC
* Plug in power to XBox, do not turn on

When I am done with the above, my board should look like this and ONLY this:
http://www.team-xecuter.com/nandx_pics/install/J1D2_J2B1-1_0526.jpg

Am I correct that this will take care of all the physical parts of my JTAG'ed Falcon XBox?

After that, I should:
* nandpro usb: -w16 original.bin (I will rename my "7371 original.bin" to "original.bin")
* follow: http://team-xecuter.com/forums/showthread.php?t=55024
In the section titled, "Flashing XBR to your nand".

Then build a 13599 bin in "CoolShrimp's JTAG Tool v3.50" and update it from a USB flash drive via Flash360.xex?
Or can it be done through the JTAG Tool itself like the video:
[ame="http://www.youtube.com/watch?v=kuO5upHjaJM"]Jtag Tool Tutorial (Install FreeBOOT) - Cooshrimp - YouTube[/ame]


Thank you for the advice.

PS. I also noticed I made a mistake earlier, when I said, ".. bridge on the DB1F1 (no capacitor)" .. I meant J2D2.

Spot on with the wiring points.

Then open JTAG Tool

Copy in CPU Key

Choose your console from the drop-down list.

Go to settings and change the wiring config to AUD_CLAMP only.

Click Create Freeboot and select your original NAND dump.

Once done, click write .bin and select the newly created Freeboot.bin

At least with the NAND-x fitted you can read/write to the console at will. Just take your time installing the QSBs and you'll be fine.

Just wanted to say a BIG THANKS!

Console is up and running .. just took a little bit more since I needed to learn about moving bad blocks as well.
