Xenon install issues

[Skinleech]

Ok, so a few weeks back I got hold a Xenon console from a friend so I could JTAG it. I'd already used the QSBs that came with the package on another console (typically, the CB was not exploitable) so went straight for a wires install. I was able to solder each wire without issue except for the yellow wire on J1D2. I had a major struggle in getting that in place but eventually succeeded.

From there, using Jtag Tool 1.74, I was able to dump the NAND 3 times, with no bad blocks. I compared each NAND dump and they all came back 100% ok. I then flashed Xell back to the NAND using the Jtag Tool and soldered in the Jtag kit. Each time I tried to boot Xell, no matter what jumper setting I tried or whether I used the regular power button or the eject button, I got the E71 error, so figured it was probably my soldering. My plan was to re-solder & try again, then remove Xell to make sure it was all OK, and use Nand Pro to flash Xell manually.

I redid a few points, and in moving wires out of the way from the NAND-X install, pulled that frustrating yellow wire away from the board. again, I tried several time to solder it back in place, but had no luck. In the end I gave up, removed the wires entirely and ordered a new QSB set, soldering them in. Now, when I try to hook up the NAND-X I get the flash controller error, so I'm somewhat stuck with the following:

1. I must have messed up the yellow point at J1D2 and need an alternative so I can remove Xell and try again
2. Either my Jtag install must suck or the Jtag Tool flash of Xell has gone wonky.

But without fixing one I can't fix the other.

From reading around, am I right in saying that J1D2 yellow is a ground point, and I can just solder a wire from the NAN-X pad to a board? Presume I need to use a fibreglass pen to expose some copper on the board? Any assistance will be much appreciated.

Here's pics of each of my installs - I know there's too much solder round most of them. I re-applied some to try and ensure that all the connections were being made.







Thanks.

the yellow wire from the nand-x is a ground, the other alternative spot is J2B1.12. The earth points are always the harder ones to solder for some reason I find. You can just get a little solder on the end of your iron and dap a spot on the point then tin the yellow wire and tack it to it. The e79 error is probably beacause of your soldering and using the qsb's. Try the direct wire method again, doing this has worked for a few people ive helped lately with the e79.

Great, thanks for the advice. I'll hopefully get a chance to take a look at it this weekend - it's been sitting in the corner of my PC room for about 2 weeks now.

I'll report back with my (hopeful) success.

Fingers crossed mate!

OK, so I finally had some time to look at this last weekend. I removed the QSBs and went back to a straight wires install. It's a bit messy, but I think all the wires are soldered in a-ok. A continutity test came back fine for each point, though it was fluctuating between a readong of .000 and .001 having falled from a higher value once the connection was initially made on each side of the points.

I'm still getting a "cannot detect a flash controller" error however. Any further hints? The ROL & PSU are plugged in when I try, I've used the jtag tool and nandpro directly. I'm sure this isn't an issue, but would I have more luck if I used a motherboard USB conenction to the Nand-x? I'm currently using a front panel.



There's the current install - I'm wary of desoldering & resoldering anymore as I'm already concerned I've damaged the points.

Thanks.

hello mate, i had the same issue, what i do now is cut off the end of resistors or diodes and solder them to the wire itself....Then heat shrink them in place, it works like a treat and took me around 10 mins in total to complete. I can post pics if needed

hope this helps

Thanks mate, but I assume you're referring to the Jtag portion? At the mo I'm ignoring the fact that Xell isn't booting as I want to be able to read/write the NAND again, which is where my issue is coming in. All the NAND-X points seem fine in a multimeter, but I get the "no flash controller" error and really don't want to desolder/resolder again for fear of damaging the board.

Cheers.

try soldering the wires directly to the same points on the bottom of the board,

I tried that, thanks. The black point was deffo bad on the underside, no flash controller detected again.

I'm going to send it to a pro to get it taken care of, as the alt points are likely going to be neded now and are probably beyond my skill.

Cheers guys.
