I like the 3 x 330 ohm resistor wiring, never had a problem with it. Also to write Nand i use 47ohm resistors and not 100ohm, i found 100ohm was too high causing erratic reads.

Hi

I'm just tryed read a nand and everything look's good but never get a same results.
I did a couple of times but never same the dump's. just only 1-2 row diferent
compare with total com.
any idea what do i wrong?

Changed the massive pic to a link

Here is the output:

Hello there, i'm looking for kindly help, i've a problem writing back my original nand into my xbox board, i think there can be some bad block in my nand i don't know how it happened, is there a way to verify bad blocks?, my board doesn't start anymore and i'd like to recover it in some way, the problem is for sure the nand, anytime i dump it gives to me a different result but reading and writing processes show up no errors so everything seems to be right, i don't have the jtag installed, just the lpt one and i've tried out with and without the diode.
Perhaps my nand has blown up and perhaps could be a way to recover or substitute it.
Any help appreciated, thanx in advance guys!

I just set up the JTAG wires as shown in the diagram. How do I tell if it worked? one tutorial says it wont boot up when JTAG wires are in place but my xbox still boots up, it just takes about 15 seconds. I have a Xenon board with a CB version of 1903.

you really need that pic that big?
good post though.....nice addon .....for the cable at least......as long as the wires ain't to lard to solder...

some11...can you let me know how then wires work out ...

@under420dog
I did PM a mod to edit the post so I could make it smaller..

Anyway - that wire work fine for me! (=

I am just about ready to do the JTAG hack, but i only have acces to 68 ohm resistors and 120 ohm resistors.
Will these do for the JTAG hack ?? I am completely unable to find and/or buy 100's , either locally or on the net.

i got the same problem with my xenon here (CB 1903 LDV0)...

tried new diodes method but did not work (no xell/xbr booting), only green light and blank screen.
flashed the original nand image back and it booted to nxe 7371 like normal.

did some research and found some people did not succeed with new diodes method and suggest to switch back to old 330 ohm resistors trick.. http://360mods.net/i...a...ic&p=129110

tried the old 330 ohm resistors trick but still no go for xell or xbr.
flashed the original nand image back and it booted to nxe 7371 like normal.

fyi, i have good connection of lpt and verified my original nand image with degraded v1.1 which showed only one bad block (error 205 reading block 234) and has been remapped to the spare area in XBR image...

I have this to,just flashed xell for xenon1921 to my xenon cd 1921,and black screen ,green light,My nand dump has no badblocks,my jtag conections are fine there in no way of any bad soldering.I'm using the new method with diodes, I dont understand why its not working:( .... maybe I will try with the 330ohm resistors.

yaro127 · « **Reply #27 on:** February 14, 2010, 04:18:00 PM »

I just flashed xell once again, this time I'v changed the name of the xell file from "xenon_1921hack.bin" to "xell.bin" and now it works!!!

Can someone help me please, i understand everything but one thing what may make me come across stupid.

is there a certain type of diodes to use?

i need to purchase them soonish but one website tells me to use 1N914, another tells me to use 1N4148 and another one tells me to use both :S

Going by this image:
IPB Image

what ones do i need and what one will go on the yellow and what one will go on the blue?

never used diodes before in my life so i dont know what one i need.

Thanks for any help.

Liam

I had a similar issue with a falcon last week, it would not boot with the XBR nand flashed, but would with the original nand flashed.

If you are using the latest version of nandpro, when writing to the nand replace -w16 with *w16

In nandpro 2.0d automatic checksum (error correction) calculation was disabled, the above just re-enables it. Fixed XBR on my falcon.

ex.

wrong:

CODE

nandpro lpt: -w16 XBR.bin

right:

CODE

nandpro lpt: *w16 XBR.bin
