Help with Jasper 256 no glitch and 0022

[xostia]

Hi:

I have a Jasper 256 CB_6750 with dash 13599.

With nandpro, I get always:

...
Flash Config: 0x008A3020
Block Size: 128KB Block Limits: 0x000000..0x000FFF
File: minand.bin
Reading
Error: 250 reading block F70
Error: 250 reading block F78
Error: 218 reading block F7E
0FFF
...

I did it many times and, always different in block F7E (no problemas with F70 and F78). Opening all of them with XNand Healer 0.73 there are no Badblocks or ECC errors.

Is that normal?

Anyway... whith one of them, I prepeared with Multibuilder 0.7 the image_00000000.ecc.

I soldered the cables around the motherboard and started up the XBOX with the original NAND. It boots normally, no problem.

I soldered the cables to the CoolRunner but... It does not glitch at all, Xell never appears on screen (HDMI or composite cable with 2 audio outputs).

I revised all again and I did not find any problem in the solders...

I gave up... flash again original nand with:

nandump lpt: +r64 mynand.bin (Edited)

... and now... 3RL with 0022 code.

Anybody can help me? because I do not understand anything. The cables were connected and the XBOX started up perfectly and now, disconnecting the CR, I does not boot (with again the original nand... and sure I copied it right because I read it again and compared with the bin I wrote).

Can it be due to the ECC errors I got at first? because the solders I think they are OK (at least they were). I tested connectivity in CPU_PLL up/down and it is ok, connectivity in HANA and all seems normal...



Thanks.

Cr flashing grean ???

 

[xostia]

Yes... flashing green without dvd, solid with DVD... after around 15-20 seconds, 3RL 0022... always black screen, nothing on tv.

I am getting fool testing all but I do not find anything.

 

[esbmaepo]

I gave up... flash again original nand with:

nandump lpt: -r64 mynand.bin

... and now... 3RL with 0022 code.




Thanks.

If you used this command then you havent reflashed your original nand.

The correct command is nandpro lpt: -w64 mynand.bin

 

[xostia]

Oh! sorry... I used nandpro -w64... and later again -r64 to compare with backup file used to test if they match... and yes, they match. Theorically, it is well flashed.

I was comparing my NAND with another NAND with the same dash version, JASPER 256 and, in the blocks with ECC errors, there are only Fs...

I am suspecting of any kind of ECC errors detected by the console and it shows 3LR 0022 but why? the data is the same than before! I suspect of block F7e (the one I read more than 30 times from the untouched nand with nandpro and always gave to me slightly different values).

If you have any idea, I would be greatful.

Thanks.

P.S. This is my first XBOX 360 but I prepared more than 20 old XBOX (Xecuter) and my solder skills are quite good (and in fact this damn machine booted whith cables in the air before I installed CR).

pics of your soldering then please.

Hi:

Thanks for your help. Here can you see some pics of the difficult points (I removed the easy)

https://picasaweb.google.com/101558303146911777176/XBOXDead

I released the CPU_PLL (no boot) and joined it again... touching the leg of the resistor thinking that this could be the problem (no boot). Later I release the X and tested the continuity with the other side (idem). I tested continuity with all the points around (spots and resistors) and no problem, all seems ok. There is no ground connection... I do not know.

I measured the resistor near hana (33Ohm) and all the lines are independent (the contact next to where I soldered is not communicated).

The incredible thing is that (except the CPU_PLL that I resoldered to try again) all is as it was when I soldered the cables and booted the XBOX with the original NAND (I even read 3 backups before... with that 3 ECC errors at the end of 64 KB).

Yesterdary I gave the CR to a friend (I warned him about my case :facepalm and... It is working in his Falcon (3-10 seconds to glitch).

I think that something burned out... oh sh*t. I prepared (for friends... I never earned a $ of these things) so many machines (routers, old xbox, satellite receivers, etc.) and this is the first time I fry something. I feel disapointed... It is not the money (at least this one is mine) its my proud .

I keep on thinking that is some kind of nand-software error... or any soft hidden protection on this Jaspers (simulated as ECC or badblocks). Sorry if this idea is stupid.

I you have any interest about research what can happen (I red a lot in forums and I know that more people is suffering similar cases) I can send the motherboard to you for free (no return, no problem at all).

Thanks and I apologize for the inconveniences.

- Xostia -

P. S. You can see the CPU_PLL a bit big but it is simply that I soldered two threads of the cable and joined the rest on the upper part (to make it a bit more solid).

 

[chossy]

That soldering is awful looks like you have got some shorted points there remove and clean it up with braid then check the points for damage.
I personally would leave it and get a pro to sort it out before you cause any more damage.

 

[Martin C]

Take a pic of your coolrunner.

"I keep on thinking that is some kind of nand-software error... or any soft hidden protection on this Jaspers (simulated as ECC or badblocks). Sorry if this idea is stupid."

The problem is you can't solder. CPU_PLL_BYPASS is bridged. If you're happy to kill the console, remove all of your wires and flash the original NAND back. Make sure it boots.

 

[xostia]

...all of them are tested... and once installed the cables it was working with original nand and booting games beffore the CR soldering to these cables.

I only "retouched" CPU_PLL... (to try again) and now it is not nice but all seems be ok as before (tested all around the board).

... probably I wil desolder all... but this will not be the solution, for sure.

I think that will need to give up.

 

[xostia]

Hi again:

OK... that is what I will do. The coolrunner is installed in my friend's xbox... and working without problem.

... Tomorrow I will go with the box (as is) to meet a colleague that repairs any kind of small electronics. He will test... and we will see (no hope).

Thanks.

Hi all:

Finally my friend called me today and... we were testing - disconnecting - testing all last hour and a half.

We started with HANA cable. We tested Hana and the line is perfect, the resistor next to it is 33 Ohm.

CPU_PLL was OK (with connectivity with the other side of the board and no joints around... the next spot, most dangerous, was covered/protected with small piece of tape when I soldered). After getting out the cable... the small spot was out and no connectivity with the resistor and the other side (we only can see in the spot place the tube through the board). The resistor measures 10KOhm. The board in this zone is completely clean exept no spot. We will try tomorrow to bypass the connection between resistor and the small point on the other side of the board.

Anyway... for your information, every time we disconnect a cable we tested the box and the effect as:

- More or less 5 resets, I suppose (fans were up and down), and after around 20 seconds -> 0022 (that was the behaviour always after CR disconnection but whith cables on the board soldered). That is, no change.

After last disconnection -> CPU_PLL (and without the spot, CPU_PLL clearly "disabled" on the board)

No resets... simply after 5 seconds -> 0022

Right now, I have 2 problems on the board: the original one (I still believe software) and broken CPU_PLL. I am sure that, when I repair it with a cable... motherboard will start to reset again as before.

I will post some pics but I am flashing with nandpro lpt: -w64 mynand.bin the original (yesterday I tested with *w64, that reconstructs the ECC data). This way, it will be "original" when we restore the CPU_PLL connection.

I thought about efuses... but It should be impossible because I updated dashboard - tested a original old game - and made the backups after that.

... I think that this will be my first and last XBOX 360.

God saves old XBOX with Xecuter2 and XBMC.

Thanks for your help.

P.S. I will post some pics of the motherboard cleaning when the flash procedure ends.

Here are the pictures of the difficult points without the cables:

So you've lifted the VIA pad below R7R17. You MIGHT be able to get it working by repairing the trace. When I say 'you', I obviously mean someone who can solder.

 

[xostia]

Hi:

The pad was out removing the CPU_PLL_BYPASS cable. Before there was connectivity with the other side (near CPU).

In fact, the 0022 appears too... but now after 4-5 seconds with no resets, and before there were some resets (fans jumping... witout chip) and finally 0022.

I will repair this point with my colleage... but I believe that all that I will get will be the "previous type of 0022", for sure.

I'll keep you informed.

Thanks.

 

[xostia]

Hi again:

We CPU_PLL and now the box keeps on showing the 0022 (as previewed), again resetting 5 times (fans jumping like a glitch but without glitcher !?) and, at the end 3RL and 0022 (fans normal). With CPU_PLL disconnected the 0022 appeared instantly after boot.

My coleague soldered it on the same side (the bottom), joining the resistor to the tube that goes through the board, the tube was very visible. Here are some pics:

https://picasaweb.google.com/101558303146911777176/RepairCPUPLLAndICSChip

We tested with the other side and there is continuity between the points (tested before and did not).

At least now I have the same problem with wich I started...

We were looking for something all around the motherboard and only saw small solder rests on the ICS chip (NIC) ... we cleaned but it seems that all was ok, no difference booting.

So many people whith exactly this behaviour... it is not normal, in this and another forums...

:mad2:

Thanks for your help.

 

[Martin C]

What resistance do you get on CPU_PLL_BYPASS?

 

[xostia]

Hi:

When the CPU_PLL_BYPASS was disconected I had 10KOhm, not shows around 9KOhm.

We tested the points around and there is no continuity or short with ground.

It is a mistery for us.

Thanks.

 

[Martin C]

Can you post a pic of what points you connected for the trace repair ?

 

[xostia]

Hi:

Here:

https://picasaweb.google.com/101558303146911777176/XBOXDead2

you can see the image before reparing and the same with two orange circles indicating what we joined together (we put the end of the cable on the tube, via as you say, and solder there and on the resistor leg).

I do not know if there is something between them... but theorically not, only the broken line from one to the other.

Thanks.
