Jasper 512 wont boot

[Gasek]

Hi Guys,

I have installed the coolrunner in my Jasper 512. No problem for me, I have installed modchips in PS2s before, so soldering isn't a problem. I've got down to writing the ecc on ht enoob tutorial. When I've got to the let's turn on your XBOX step, it will not turn on. So i have checked the soldering points with a multimeter. On the excellent tutorial by ccNick he says: If your first NAND dump was bad and you then write over your XBOX's NAND with a patched version of your bad NAND dump then your xbox is totally useless to you. Is he saying that it wont even turn on? BY THE WAY: I did check the nand files before I performed the write.

I have removed the coolrunner completely from the motherboard thinking that perhaps it would at least turn on when pressing the eject button, but it didn't help.

My guess is that this Jasper is bye bye. Is there anything I can do? (Rewriting the XBOX with a bad NAND would make it not boot?)

Can you read the nand now?

if not then sounds like you have a bad flash! You can try shorting the nand, or give it the 5v requried, do a quick search on here for shorting nand etc..

Thank you for your reply. I can try that but I am interested in knowing why it wont even turn on. When the coolrunner was installed, after the write to the nand, the red led on it was the only thing that would be on.

Right now it is disassembled (the XBOX) and I haven't screwed in anything. I wonder if there is a step in assembling (for testing purposes) that I missed. I have it inside its cage (motherboard), with the front ON/OFF panel attached, no screws anywhere, fan is plugged in however DVD drive is not. I tried plugging it in but it doesn't make a difference.

In the mean time I will read what you suggested: shorting the nand

 

[seanr28]

only do this if you are unable to actually read the nand. and the best option to try first is to give it 5v...

I've got down to writing the ecc on ht enoob tutorial. When I've got to the let's turn on your XBOX step, it will not turn on

1. What command did you use to write?
2. Can you check your original NAND dump in 360 Flash Dump Tool and let me know if you have any bad blocks?
3. Try Multi_builder to create the ecc file.

Hi Martin,

1 I've used the JTAG tool to write. From this tutorial: http://www.team-xecuter.com/forums/showthread.php?t=75945

2 I have a windows 7 64 machine and the bad blocks tab is not showing. I tried the windows compatibility modes but the tab wont show. I eve ndownloaded version .97, but the bad blocks tab wont appear. I will keep trying ...

3 Multibuilder does not work on my machine WIndows 64, even if run as administrator ( I am logged in as administrator). Is it supposed to work on on win 7 x64 machines? (Damn, damn, damn)

 

[Martin C]

Can you still write to your NAND?

Try writing back the 1st 50 blocks of your NAND:

nandpro usb: -w64 nanddump.bin 0 50.

See if you can get it to boot.

If there's no bad block tab then there are no bad blocks - it's all good

What happens when you try to run multi_builder?

 

[Gasek]

It (multibuilder)gives me this message: Windows cannot access the specified device path or file, you may not have the appropriate permissions. I am logged in as admin and have run it as admin. It is the run command when I double mouse click on it. My guess is that the modules work fine. It seems to me that the run command is just like .bat file which puts together the other modules

Now to the NAND. I thought the QSBs were too difficult to put on the board so I soldered all wires (I am ok with soldering) and I have removed them all to try and make the XBOX boot back. To try anything I will have to solder them back or work on the QSBs which now make perfect sense as to why you would use them as opposed to soldering the wires.

Please be patient with me but keep helping. Your suggestions make a lot of sense. I am starting to think that the programs to read and write the nands on my computer were not working properly due to Windows 7 64. If that is true, I would think that other people would have reported this before. So I will be off for a while to, this time, solder the QSBs to the motherboard and check back with you but it might take a while.


This is very comforting: If there's no bad block tab then there are no bad blocks - it's all good but I thought it should show even if there were no bad blocks... You know it much better than I do so you must be right.

Thank you very much for your help so far.

ok - post a screenshot of what you're trying to run for multi-builder.

As for the wires etc. You don't need to remove ANY of the CR stuff to read/write the NAND. It has no impact on the work whatsoever. I solder everything in place first, then do all the software stuff.

maybe you've damaged the orange wire pad, thats usually the mess up some people get, i know uve got alot of experience but you never know, I did a trace repair on my mates xbox the other day and i was the one that damaged the pad in the first place and i concider myself a good solderer.

Just try reading the nand, if that doesnt work thats the problem, if it works fine try flashing the first 50 blocks like MartinC said, if all of that fails then youve broken the pad, i know u said u used a multimeter but just look it over again.

 

[Gasek]

THanks Martin, that's what I did. Soldered everything then attempted the software part. I must have screwed up somewhere for it not to turn on but after removing the soldered wires I checked everything with my magnifier/light arm, they all seem fine.

So you are saying that I can solder everything back directly to the motherboard both for the coolrunner and Nand -X wires and leave them there? Like you said, if the dumps are good I don't really need to resolder the nand-x wires, just the coolrunner wires, right?

 

[Martin C]

yep, you can leave everything in place.

 

[Gasek]

Anything is possible Modcus. I will recheck the pad but you mean the point on the xbox motherboard right? It looks fine and I just checked with the multimeter again. I also took a picture previously with my CrApple Ipoo 4S. Solder is not splashing over to the neighboors. I use a 15 w solder, the 30w might be too intense for this kind of work.

Unless you messed with the soldering after flashing the ECC and powering it up, it's not going to be that. JTAG Tool has been known to build the wrong ECC, causing your console not to boot.
