manufacturer for code FF not found

[Ty13r588]

I just installed my demon on my trinity and plugged everything in to read my nand before proceeding to install my rgx. I get manufacturer for code FF not found error each time. Any suggestions?

Use a multimeter that tests for continuity (most do).

First of all, test the points next to each other (on the DemoN) to make sure that none of them are bridged.

Once you have done that, test each point against the NAND pins on top of the board.

If they all check out fine, test the pins on the ribbon socket against the pins on the external module.

My last two nand qsbs appear to be bridged but Im having a hell of a time disconnecting the two

Use some solder wick

Flux the area and use some solder wick to mop up the excess solder.

There are videos on YouTube which show you how to do this properly.

It really helps to apply a little bit of solder to the wick first and then use it to remove excess solder from the board.

I bought solder braid at radio shack but this may not do the trick. It sticks to the board and appears to be entirely copper

Did you read what I posted?

 

[Ty13r588]

Yes. Is this different than solder wick.

Not at all.

I think you should watch a couple of videos on YouTube and learn how to use solder wick/desoldering braid properly.

the two no longer appear bridged but i recieve the same error

I'm not even seeing a power light on the DemoN USB in your pic. Do you not have the PSU connected?

 

[Ty13r588]

I have a multimeter but am unsure what to do with it

Why do you think there's a card in the DemoN box? I suggest you read it.

 

[Ty13r588]

yes the demon is recognized in jrunner and the light has been on. Ive toggled both nands but still cannot read

- - - Updated - - -

after the second attempted read each time jrunner quits

 

[Ty13r588]

I realize this. I get the same reading on each oint but the four in the corner get no reading

So it's failing continuity, meaning it's poorly soldered.

Where are you located?

 

[Ty13r588]

U.S. Should all points have a consistant read?

 

[Martin C]

Each QSB point on the DemoN should have continuity with a point on the console's NAND, because that's what it's connecting to.

 

[Ty13r588]

Where do i measure the consoles nand

You need to get some closer pictures in particular the smaller points on the board. Did you try and read the nand before connecting it up in the board by any chance?
