Fixed the errors from earlier, had to remove the resistor on the jtag wires (which stop E80) to be able to w and r.

correct, you have some major issues here. Did you flash the KV and config files back? I am assuming your dump did not have these errors in it.

I have a taggable xenon that the solder points are in bad shape,  been seaching all over looking for a way to pic up other points . there are the points that are bad. where the resistors are and where the wires go across from them ... looking for a way to altenate these points to make the the jtag useable. thanks.

You may be SOL.

I know where the other end of your wires come through on the underside of the mobo, but not the resistor side. I have a zenon at home I can trace out this weekend if you would like. If you find some post them here so I can update the tut, but I dont think you are going to find a picture already posted...

thanks . I think it can be done just going to take time and patients to add a wire to the traces, I just want to make sure i get the right traces and make sure i dont tear them or anything.  thanks matt. i been looking havent found any pics or anything yet.

try this method using 2 x switching diodes from j1f1-4 to j2d2-2 and j1f1-3 to j2d2-1 the diodes are 1n4148
and add a 100ohm resistor on j2d2-4 to j2d2-7
if not get out ur multimeter and check the V j2d2-1 and j2d2-2 they should read 1.5k with no power connected

oh lol didnt know if it was confirmed that the pads were bad
any evidence of tampering before u got ahold of that console rodent?
and i dont think there is alt points for xenon boards
yeah the only thing i can think of is try to make a connection before the pads by scratching the traces

yes it was tappared with and the J1f1  area in pretty bad shape and the j2d2 pads the traces are gone around some of the points so hopefully i can get time to sit down and follow the traces and get this thing jtagged... I just asked cause i been looking for 3 days now and think i looked at everything twice maybe 3 times over again.


Thanks for all your help guys. hope together we can get this working :)


 November 14,2012 Edit: if i have to I will totally rebuild the trace i have another xenon here that i can see the traces good, and i will try to rebuild each trace ... If you guys think that is impossible tell me know before i pull my hair out....lol

November 16, 2012 Edit: well i been up since 4am this morning now 3 1/2 hours later I checked everything twice seems like i got all good connections, hard wired the 3 bad traces everything seemed to be going good , dumped the Nand , Flashed xell and Still E-79... removed the resistors and the wires again. only thing i guess i try now instead of Jtaging the xbox i update it, dump the nand again after i Rgh it to get the key and make this a flashed console instead. looks like its the only hope to save another xbox from the junk pile.
