I got an Xenon and dumped the nand 5 times without resistors.  the first two where terrible but after resoldering i got two dumps with no errors and they matched 100%.  So i extracted KV and Config through nandpro20b.  Injected them into XBR 3 for Xenon from xbins.  I put Jtag wires on and got E79.  everywhere i searched said to check KV and Config.  Since the dumps were perfect they config and KV must have been.

Anyway i seen a tutorial on fixing a bad flash by using a donr nand nump but in order to do it you needed your CPUKEY which obviously i didn't have due to christmas lights.  So i restored the orig.bin but the xbox was just booting and after 15 seconds it would go to RROD with error 1033.  So with the orig flashed i put Xenonhack.bin on to get my cpukey so i could set about creating a donor nand image.  I managed to create the donor dump with my KV in it.  Now it is bad as after flashing Xell i removed th LPT wiring to put it onto my donor board and after reading the nand of that a few times i put the wiring back onto the knackered board but now all i get is no flash controller found.  I have tried on 4 computers with no luck.  And with and without resistors?

I am out of ideas now as Xell boots fine on the xbox so nothing is shorting anwhere and i have been over the soldering and wiring a million times.  I have checked everything else ie power cable is plugged in and on,  Soldering is fine,  Bios on pc is all set up perfect.  

Any info would be mint.  Thank you

PS Something i noticed,  When the xbox is plugged in and has AV cable in and the LPT is plugged into PC,  I turn the xbox on and it boots to XELL and when i type and commands to read or write with nandpro the xbox turns itself off???  Is this normal?

the xbox turning off when you flash is normal.  

when you flash the kv and config, are putting the right nandpro commands in? ie nandpro lpt: -w16 kv.bin 1 1 and nandpro lpt: -w16 config.bin 3de 2.  Alsodid you use those when you read them from your nand image

Try erasing the nand: nandpro lpt: -e16 , then flashing the xbr image without injecting the kv and config, then flash the kv and config directly to the nand.

 That is my method, and it always works.  injecting kv and config into the image has not always worked for me.

thanks for the reply.  yeah i did a falcon a few hours before i did this xenon and the commands were all right.  I cant erase the nand as it is not detected in nandpro anymore.  even though the xbox turns off when the lpt is plugged into pc.

If you can boot Xell try flashing the NAND using Gentoo/xbrflash method.
I could not get XBR to work after flashing over LPT, but after flashing in linux it boots fine.

If you can't get Xell to run, then try the bad flash recovery method (shorting some data pins on NAND), then erase and write just Xell using Nandpro/LPT, then boot in to linux and upgrade to XBR using xbrflash.  This method is much faster and more reliable than writing the whole xbr over LPT.  I just hope your KV/Config files are good.

Well i think this board is dead.  I flashed XBR through the debian minicd following a tutorial on the forum and it goosed it.

The tutorial said to flash the xbr.bin with my keyvault and config already injected.  
So i did and then it said to flash the actual release from xbins after my xbins.  
Something to do with verification,  Now to me that meant that the release would be stored on the nand without my keyvault or config.

And i was right as after i followed the tutorial i turned of the xbox and back on after a few minutes and then i got the E79 error.  And after retrying the lpt bad flash method i now get E64.

So since i cannot flash via LPT and the xbox does not boot i tried to install my cygnos v2 but it is giving errors aswell.


The LPT connections are pretty messed up now on the board so is there any alternates.  I tried to follow a trace from the one i pulled of earlier but i still cannot get any detection.  But it still turns off when i try to read with nandpro and the xbox on.  So its definatly talking in some way.

It sounds to me like your issues with the original board were with LPT wiring issues.  I don't believe your first (and successive) writes were perfect.  It is possible to have a cable which can read good dumps, but have silent errors when writing.  The way to see if this is the case is to flash an image to the nand and then read it back.  If you compare the image to the dump and there are differences, the image wasn't written correctly to the NAND chip.

A way to remedy this problem is to shorten your cable up as much as possible; I had success at about 18 inches, others say 12 inches.  If you have really bad soldering jobs, this can also cause interference.

Solder joints should be shiny and shaped like hershey's kiss candy.  If you have excess solder or bridges, use solder wick or a similar solder removing device, and suck it up. Do this with every connection.

thank for the reply.  The soldering looked nice and shiny and like little balls on the LPT and the one on the board went through the header holes and again were shiny too.  I am in the process right now of attempting the cygnos again.  Two more wires left.  Hopefully i can get it to write my xbr.bin
I have checked the orig.bin over in 360 flash tool with my cpu key entered and everything looks fine so i will extract Keyvault and Config again and hopefully cygnos will not give me any errors this time and just write xbr.

I will keep you updated.

thanks for replying.

If you have balls of solder that means you are not soldering correctly.  Most likely you are heating up the solder directly.  Prior to joining a lead or wire to a point on the mainboard you should tin the lead/wire by heating it up and touching the solder to the wire (not the iron tip).  Then heat up the point briefly, then touch the wire to the point.

I have been tinning the iron tip then touching thw wire to the tip then putting the wire as close as possible to where it wants to go then heating up the motherboard point then pushing the wire through.

Is that an inncorrent way?

Thanks ans i have never had any problems doing any of the other xbox this way.  It is just this one thats causing me problems.

thanks
