[FIXED]Xenon cant read nand, Zephyr it can!Nand-X FIXED E79 also! read

Dear people,

Just gonna start off, i know some of you will see me as a troll/rat name it how you want it ^^ But i got a problem and wanna ask it here :p

I have bought myself an jtaggable xbox Xenon cb 1903
dash 6717, but updated to 7371.
I have installed my nand-x directly to the motherboard with the pcb's cause ive read that the most secure way is directly.
In the beginning he read SOMETIMES my nand but gave 'reading error 0' for ALL the blocks. So after some googling i was told bad soldering. Wich i could not believe. He did the reading like 2 or 3 times but always error 0 and from then my nand-x refuses to read my nand.
I have tryed everything from the sequence plug in first power cable (but not turnd on ofc!) av cable, usb, you name i did it :D

Then i was starting to doubt if my nand-x still worked perfectly, cause my Xenon refused to be read.
So i tryed my nand-x on a Zephyr motherboard i have and guess what my nand-x read it from the first time. So im sure that my way of working: plugging all in, soldering, software related is OK.

So now im here to throw it inside the group to hear some ideas about what can i do?? Cause im getting desperate :(

I will upload pics in a little of my decent soldering work!

Kind regards :cool:

The soldering looks fine.....

Maybe the wires themselves have some problem. Wait, on the Zephyr, the NAND QSBs are soldered, right?

that trace is not used by the nand-x connections.
and i did not use the qsb's for the zephyr, so the direct wires to the board.
ps it was the connection more up, so i fixed that.
Now i can dump my nand, but i got a 3rrod with code 0020
So i can read my nand but not dump it with xell cause no screen since the xbox wont boot.
Any ideas on this problem?

0020 is more than likely your GPU needing a reflow.

could you give me some more information what a reflow is and what it does? Cause the error code 0020 showed up from nowhere. Before he booted fine.

Maybe you guys will call me crazy or w/e:
but before i found that bad solder i tryed to short the nand also used pin 41 and 44. there was also a tut with pin 28 32. Is it possible that i f**ked up my nand wich gives me error 0020? If yes is there a way to fix it?


ps: if i founded the bad solder connection sooner i did not do the shorten nand tutorial ffs :(

On a 360, a GPU reflow is where to attempt to increase the board temperature and that of the GPU to a level where the BGA (Ball Grid Array) solder is molten, thus reflowing to the GPU and the board underneath. It's carried out using proper reflow equipment and needs to be applied using a 'profile', so the temperature raises at the correct rate so as not to damage the GPU or board.

Ok and my answer what is a reflow is answerd but what about:
but before i found that bad solder i tryed to short the nand also used pin 41 and 44. there was also a tut with pin 28 32. Is it possible that i f**ked up my nand wich gives me error 0020? If yes is there a way to fix it? :D

No, it wouldn't give you error 0020.

I've shorted all the pins on the NAND before now and at worst, you blow the NAND. 0020 is generated from the GPU.

so can I fix it with an x-clampfix? I did those before, but i dont know how to do the reflow and i wont risk doing it. Dont wanna brick ymy xbox :p

So main question: Will i fix the 0020 code with an x-clamp fix?

btw already thanks for the help :p

It depends on how bad the BGA connections are - you MIGHT get away with it, however you may need to get someone to reflow it should it not work.
