nand keeps corrupting

[afsilver]

is it possible to test it?

i'll solder the wires and test anyway..

Looks like i smashed c3b8 wile installing the pin-headers, what is it and is it relevant?

Get a reading from the damaged side of C3B8 to C3B9.
If it goes to zero it should be okay

13ohms but it beeps...

Should be okay. It beeps because there is a connection. It should go to zero if you connect test leads to same side of the 2 caps

it's writing! awsome! now to see if RRoD has gone.. or is there more to do before i hook it to the tv?

Not really i guess. All your trouble comes from bad header pins connection. Credit to MARTIN C for spotting wrong FlashConfig.

But what about your original nand. Hope thats ok!

so heres the thing, during read back after the successful write i noticed the fans started spinning!! and at the same time i started getting errors in nandpro...

wierd thing is only thing i had connected at that time was nand-x and the fans, no RF-module, not even the wind-tunnel was in it's place! earlier i've been dumping/writing without fans connected. perhaps the reason i get errors is because the xbox is actually running?

Sounds crazy! Wouldn't you have noticed the heatsinks getting burning hot then.

 

[abyss]

that's pretty weird yeah. you got the rf module in place when doing this?
if so, do it without it.

greetings

 

[afsilver]

only nand-x and fans (and of course the psu) the RF module is sitting tight on my table..
does the xbox or nand-x take damage if it happends again?

 

[esbmaepo]

Hope you have good original nand. As I understand you have read it with bad pin header connection, so you may not have a good nand!

NandPro v3.0a by Tiros

Looking for usb interface device
Flash Config: 0x00023010

this is what i get after earase with 5volt mod..

i'm not giving up until i can't write any longer

If needed, you can build a good NAND as long as your decrypted keyvault and config can be extracted from the original.

Yes thats the right Flash Config.

 

[afsilver]

so ive got the flash config... and i can write and erase the nand but it errors if i read it..

reads the first 10 or 20 blocks fine then error 600 reading block xxx...

this is still with the 5volt mod. since the xbox turns on if i use the psu..

if i ever get it up and running again that is.. is it possible to check if my KV and config is good? without cpu key?

 

[Martin C]

I think you should stop. You have a short somewhere if the console is turning itself on. It's also the reason why you're getting errors.

You might be better to flash an ecc to it and then do the full reflash with your good nand via Xell and rawflash.

If you are reading with your original nand and getting these errors then I think your original nand is corrupt. And it does make sense that it is!

I beleive you can download a clean nand from JTAG TOOL, and then try to build a GOOD nand as MARTIN C points out

as martin c recomended i stopped..
put the console back together and booted RRoD 3 times 4th time i actually booted to dash!!

i could stroll around, found no mem unit so def a SB lol.

once i turned off on the other hand RR f**king oD! but no green center light just 3 red lights..

so my nand is ok at least! anyways gonna get a professional to either repair it or buy it!

thanks too all for your patience and help much appreciated!!!

Then you do have a short. Try this: plug in power supply. Get a voltage reading on that damaged capacitor, it should give you 5v. If not then replace it.

 

[afsilver]

How can i get the values for it?
I did look over the board several times only thing i found was the damaged cap..
