Could Not detect flash controller / Read 0 / 2 good dumps and never reads again

[EiRUZ]

Ok... first I soldered the QSB's onto my board

Falcon 360.

I tried to run nandpro and I keep getting "Could not detect flash controller"

so I go back over my solder, same error. you can only solder it so many times before you start to put damage to it.

so then I recheck every solder and I even try and bubble the solder to give it a little ball on each QSB pad. I get results.. I get a full dump with 1 bad block.

so i run another dump. Same dump, 1 bad block in the same spot. SO i am like ok great! i think were working... then i run dump #3. half way through dump 3 it starts throing Read Error 0 over and over in a infinate loop. So i stop the dump and I try and dump 4. "Could not detect flash controller" Reboot, same thing.. go back to soldering... try again... "Could not detect flash controller"

So is my soldering bad?

Here is one thing that I wonder about...

I have a xenon XBOX360 and a Falcon 360. I do not have my falcon power supply because I bought the box with no supply.. so I am borrowing my XENON power supply to run the falcon during this read / dump / etc. Now the power supply boots the box up and it works on a HDTV but I wonder if the power supply is causing these weird anomalies or if its really just my solder??? i have never heard of something so finnicky that I can get 2 dumps and the 3rd on never work without touching any boards, no wire movement, no anything... i feel like i can't even breathe when I do a dump in hopes it starts reading...

also I installed the JTAG QSB. Does that matter during the initial dump? I was under the impression that only the first 2 QSB's were needed to dump and the JTAG was only needed to actually run the written XEL image.

3) I don't have DVD drive or SATA plugged in during the read of the nand. does this matter?

4) I am running out of ideas

The dvd drive ishould not matter i also have a xenon MB which i was working on all day i i tryed over and over to get the qsbs to work but slways had the could not detect flash controller untill i pulled up the qsbs and soldered the wires directly to the board, i used an nand-x installation tutorial i found on google for the color coded wire so u can place them correctly... I hope this helps ur problem even though im new at this too

Please read some of the posts and stickies on the NAND-X section, there is enough mention of this topic on there.

yes sir, I read all the stickies... and there is absolutely NO information on the question I asked, which was why I was hoping to get a direct answer in my own thread.

If i have a power brick from a XENON and I use it on a FALCON

XENON uses a 203 watt supply and a Falcon uses a 175 watt supply.

yet the power supply for a xenon has more than enough watts to power the board and run the machine, but not the other way around, obviously.

so I was wonder if the NAND is so sensetive that it needs the EXACT power of 175 watts for a falcon to get proper NAND reads? because I have soldered over and over and over and after 3 or 4 solders I am thinking I am going to do more damage in the long run to the board than if it was a actual issue with the setup, like a power brick. or even the NAND-X itself is bad...

was hoping someone had some insight into the matter

Hey mate, Have you fixed your problem?
I seen to have the same issue sort of. I also have a falcon, I dumped 3 times all identical then when i dumped xell in the board it just died and im getting could not detect flash controller. Im sure its not the soldering because i removed the QSBs and soldered the wires straight to the board.
It seems its a falcon issue to me or wemay have overheated the traces on the board. Dunno, im out of ideas .

Yes. I made a new thread. I solved my problem. It was the type of solder I was using. I soldered 3 times and eventually I was about to pull the quick solder boards off and do pin headers so I got some desoldering braid. Then since I was at the store I got some nice lead free tin. Thin. Shiny. New. And I used that instead of my 10 year old fat solder that was sitting in my toolbox. And it instantly picked up and I've done 16 dumps in a row with no problem.

As this been mentioned so many times, its either one of two. A bad soldering or one of those lately boards that seem to stop working after a few nand reads/dumps.

Lets hope it stays like that until you manage to finish the JTAG and run freeboot.

Well done mate. I hope its my solder as it's quite old as well, because it was dumping fine till it happened thats why im confused. Hopefully its not those bad boards that manwithoutname was talking about.

Thanks for replying btw.
