What was written to the NAND? Have you tried SPI read/write since?

I believe the Original nand was written to both demon as xbox before taking the demon out. I haven't got to it to read/write yet since i reall need to go now, my wife is giving me a headache..., I'll try that when i come home again and report back. Just added the repair picture

R1T15 and R1T16 could now be shorted due to that colossal wire you used.

 

[xzanox]

Hmmm yes I see what you mean. I did check with magnifier and couldn't see any bridges but ill check again when I get home. I'm on my phone ATM. I'll get back to you soon.

 

[xzanox]

Just to be sure i cut the end of the wire on the resistor, it is def not touching anything else now. I have continuity between these points (via point) to nand legs. Just soldered nand x wires and attached nand, plugged power brick and av cable (no power on) and then

so at the moment i cant write any nand back to my mobo to see if it starts/boots (even though i'm convinced it has stock nand already.

 

[Martin C]

Check all active NAND points to ensure they all have resistance. Use any NAND diagram out there to determine this. I have a feeling something else is amiss.

You should also check for adjacent shorts on all NAND points.

From your nand x troubleshootguide my nand points now give ( without adjecent bridging) the following values:

 number 1 : 1.32 volts  
number 2: -0.01 
number3: 1.59 volts 
number 4: 40 ohms  
number 5:-0.01 volts  
number 6: 6.06 k ohms

here are two fresh pictures from it, topside and underside mobo Does it seem I have to try the bad flash recovery? I haven't tried that yet...

 

[xzanox]

So i just did the bad flash recovery with the flathead screwdriver, i attached after that the nand x to pc and nand x wires, pressed get mobo type and got this:

Flash Config: 0x00023010

Can not Continue

But when i press read nand if gives me can not continue again. I read that 0x00023010 is for trinity so i guess i am advancing right? i disconnected power and nand x, plugged back in hooked nand x again, load up nanddump and press write: can not continue...

 

[Martin C]

yes, that's good.

I think you have a bad flash. Do it again and this time, erase the NAND (Assuming you have a good dump).

Then try writing the good dump back.

 

[xzanox]

I never before only erased my nand. I assume i have to do that in Custom Nand/CR options? After i set it on 16 mb do i add blocks? (I have a good dump, saved it in three different locations.)

 

[Martin C]

TBH you only need to erase block 0.

 

[xzanox]

Ok I can try it in 15 min I think, I'll report back

 

[xzanox]

Just did the bad flash recovery again. I removed the screwdriver, left the psu plugged in, connected NAND x again and pressed get my type. Again it shows me 0x00023010. Then custom NAND erase 16, block 0-10 and than RUN.

after I press run it doesn't respond for like 5 seconds (jrunner doesn't grey out, not that not responding, jrunner keeps working like normal) and after those 5 seconds, it says again 0x0000000 can not continue and gives me that happy melody of "djinngg" like if jrunner finished a NAND read or so.
I have the feeling I am running out of options, or are we getting closer in your opinion?


Btw do the voltage of the points I've posted a few posts up, show something "special"?

 

[Martin C]

Yes - the NAND isn't initializing so it indicates you have damage elsewhere. Check all 8 resistors on the underside to make sure they're all connected and reading 10k.

 

[xzanox]

R1T9 = 9.90
R1T11 = 9.95
R1T12 = 9.78
R1T13 9.77
R1T15 = 9.89
R1T16 = 9.83
R1T17 = 10.02
R1T18 = 10.00

They seem all good...

Btw I tested this with the red stick on the near side of the via point resistor. When I switched the probes it gave eventually different values some of them 6.35 and around those values. 1 or 2 resistors gave 9.55 or so with black probe on via side of resistor

 

[Martin C]

But do you get continuity between the NAND I/O pins and the sides of these resistors with no adjacent shorts?

 

[xzanox]

Correct

Edit: I hope I'm not causing you a headache with this...I'll take care of the headache, it's causing me all day and last night already

 

[Martin C]

There's def something else amiss and it's NAND related, since bad flash mode gets the right flashconfig.

 

[xzanox]

Yes right after the bad flash mode I can get the correct flash config, but after than anything else I try gives me the incorrect status again. Btw it doesn't say it's a trinity at the last rule in Jrunner after "get motherboard type" only the flashconfig number

 

[Martin C]

Did you try to erase the entire NAND then see if you get a valid flashconfig after a full PSU power cycle?

 

[xzanox]

The moment I try to erase some blocks or the entire NAND, it gives me the incorrect status again, so even after a full psu power cycle it gives me straight away the incorrect status.


Edit: Still getting this.

Once I get the bad flash config, I need to redo the shorting on the resistors for the bad flash recovery to get the correct flash config again. But nothing after that works
