Nandpro Error -> PC Turns Off while Reading

[Tom-Soja]

Hello guys i got a xbox 360 Xenon and want to read out my nand with lpt wiring.

my setting:
xbox 360 1.0
3x 330 Ohm Resisters soldered in (for jtag)
-resisters not connected to jtag points!
LPT Port Connected without resisters
BAT41 Soldered for PIN 11 (free60 diagram xenon)
LPT Protocol: SPP (Normal) (EPP "works" too)

History:
[TRY 1]
first soldered in with 5x Resisters 100 ohm and N4148 Diode
-> No Luck by connecting lpt <-> xbox
[TRY 2 (or ..50??)]
Desoldered Resisters & again used N4148 Diode for pin11
-> Connected Fine but FlashConfig was wrong and Each Block got "Error: 0" or some other in hexvals
!!!!! WHILE READING BLOCKS IN RANGE 250-290 MY COMPUTERS IS POWERED OFF BYSELF - EVERY TIME!!!!
[TRY 3 (............)]
Replaced N4148 with BAT41 & Again without Resisters
-> Correct FlashConfig(!!) the first few Blocks got NO error mut after that every other Block got an Error.
!PC POWERS OFF BYSELF AGAIN WHILE READING BLOCK 250-290!

Big General Problem:
I have much Problems that Nandpro detects the Xbox, it seems that the Xbox must be very long without voltage and than it work. after i cancel (can not finish) a read im not able to read the nand fast again.

I have Uploadet the last File what Nandpro has Written in the 3. try before the pc was powered off, thats why its only ~9mb.

 http://www.filefactory.com/file/a213c2g/n/nand1.bin

The most Blocks was Error 0 or other hexval but First few Blocks should be Ok.

It would be very nice if anyone can Help me i want that f***ing Homebrew waiting so long with Dashupdate *crying for xbr* =)

well good news and fair news ,my friend......you can install the jtag hack...
cb 1920 cd 4342

now because of what happen you have to do this...short the nand out a certain way to make it read again
power everything up to read the nand  but the 360 keep the back of the 360 unplugged..then

as you have typed in nandpro lpt: -r nand1.bin loaded up .....press enter and plug the back of the 360 power in...it should read ok. as you see i did get a clean somewhat of a copy to load 9mb into 360flashtool so <any questions?


good luck with your Xenon

Hello and many thx for help, how can you open the damaged bin in flashtool? it gives me a error. with short the nand you mean this bridge pin41-44 thing like on http://www.xboxhacker.org/index.php?PHPSESSID=fa8c53192da01db7cf61764888a436eb&topic=14088.msg100529 or, must i bridge pin 41 to 44 only or the whole range (41 42 43 44) i have read this will delete the nand but i dont have a working image.

have i right undersand:
plug out power (waiting..)
solder switch to pin 41-44 to short them all on switch
plugin lpt to computer
turn switch to on (shorting)
plug in power of xbox
turn switch to off (no shorting)
DOS: nandpro lpt: -r nand1.bin

-> Nand can read out? that would be nice

why only -r as option and not -r16 (like descriped in free60 nand readout wiki) are there any differences?
sorry for much asking but i dont want to brick the device

Wow, hold on there.

The shorting of the NAND pins is only if you Xbox wont startup!!!(this with the lpt cable disconnected), if i understand this is not the case with your setup.

Your xbox should turn off while reading(if you have it turned on for some reason) and not the pc.

I think something is really wrong, pc will only turn off if there is a problem with the software(unlikely), or if you make a dead short and your Pc powersupply cannot handle it.(almost overloaded or just bad)

Check everything in the LPT setup before trying again, measure everything and try to use another pc, first with the resistors and diode in place and if that doesn't read correctly you can halve the resistors to something like 30-50 ohms.

How long is your cable and what kind of cable are you using?

[Tom-Soja]

hi i will try now to solder in 100 ohm resisters to the points and try reading again.. i have used wires of a standard ide cable ~25cm long.

x while i do all this read outs i get a rod error by starting the xbox errorcode is 0102 (unknown error).







why is the Pin located at 5 & 6 not groundet in the xenon diagram like the other console diagrams? should i do that?

[Arakon]

You only need one ground point, since the grounds are all connected anyways.

hey im back and have tested with 22ohms and 100ohms + bat41 on pin 11. no luck at all only with the bat41+no resisters wiring i get a connection. any ideas ?

If you have a 3,3v LPT port the resistors can cause problems, the 100 Ohms are primarely there for 5v LPT -> 3,3v Xbox and for some added protection.

As i said you should try another pc,  maby ,measure the lpt Data and control pins before using the cable without resistors.

First thanks maximilian0017 for paring in and stopping him on my user info error .

i took your 9mb and patched it into a good 16mb nand and 360flashtool seen it as valid and read it

!PC POWERS OFF BYSELF AGAIN WHILE READING BLOCK 250-290!

ya sorry ,I was to fast on the draw for a cure for you...lol

also make sure your diode is the right way.....pc powering off is a problem and getting spiked(to much of a reverse flow on whatever your doing)... make sure your grounding you pc to the 360 with a wire to...just for the heck of it...

[Tom-Soja]

diode is with black ring to mobo. my pc is a little bit outworked not good groundet, if i touch the pc i can feel a little voltage but it dont kill me there is plugged in so much pretty usefull stuff i cant belive that the lpt port is the problem. i ground the pc on the xbox (it will be a good team) and desolder the resisters. measeuring lpt port gives me 3v. to make it shorter:any other ideas if that dont will work?

monday i try this and make a copy and upload a later image. hope this time the pc dont shut down.

thank to all the great hackers helping me

you got the keyval in the image?? how can it be so much errors in so many blocks was that faked or what? that mean i have all to flash a valid xbr or?!

not good for stuff like pc's and such....

bad grounding in the house or rooms socket......you need to plug a filtered surge suppressor on outlet then maybe your problems will clear up raw low AC current running through your ground from something....

I myself ran a 8 foot copper ground rod into the ground outside and and grounded my fuse box.....most places are like this but oxidation can cause many faults with grounds...if not even a loose ground outside on the electric meter...or your pc's powersupply isn't filtering out the ac in, to it to convert it to a clean dc...
worked out great and was installed a while ago for my CB.HAM linear equipment.....

First thanks maximilian0017 for paring in and stopping him on my user info error .

Had to read it 3 times myself, i just answered another topic of the TS when i read this one and made the connection...normally i dont interfere.

If you "feel" current running through you it normally is a voltage of 50V or more, or high voltage/low current.
(this can be dangerous)

Try this:
1. Disconnect everything from the pc and only connect the mains(110/230v), try "feeling" if the pc still has that feeling.
2 A. If the pc doesn't have the problem then remove the mains and start adding devices, connecting mains and testing until you find the problem device.

  B. If the pc has the problem with only the mains connected you should try another powersupply and check every connection from the pc to the earth pin connected to the fusebox(what ReverseAffect said), normally (in Europe) the ground triggers a failsafe device that disconnects the group if a defective device is connected, this will not work if the groundpin is disconnected/defective.

One important tip!!!, if you connect you 360 to the pc first connect the lpt wires and then connect the 360 PSU to mains, also make sure the ground wire is sufficient.
Otherwise you could blow up your pc/360.....
