NandPro: LPT and USB nand flash programmer with only 7 wires

[B1N4RY]

where is this newxell full dump on xbins? I've browsed everything and can't find it.

It is now known as:
Xbox 360 > Development > Free60 > Xell_DHCP_RGB_1024x786.rar

[B1N4RY]

No problem.

Slightly off-topic:
What is the value of XEX1 and XEX2 key?

[Intersect]

Do you mean what are the keys?  xex2 is calced from the xex1 and something else at init.

[B1N4RY]

Yes, my bad. What are the keys...

[sasoseso]

XEX1=A26C10F71FD935E98B99922CE9321572

XEX2=20B185A59D28FDC340583FBB0896BF91

I'm real lost here Ive tried them all on numerous boxes and always get an E79
CB1903 CD1888 should those pre made for xenon files work with that combo or do I need to wait for a 1888 or 1903 release?

How many dumps did you make per box?
Do they work again if you flash the original images back?
When were they last updated?
Have any of them been sent in for repairs, and how long ago was this?
(you can check the cd version as mentioned here)

Could you make some photo's of the 3 resistors?

Hello,

I could use some help too.
Problem:
My console boots to e79 after a reflash of the original nand backup.
Things that went wrong.
When reading ever single time i got an error at block 57, no matter what, so the final nand dump i kept had 2 bad pages.
Things i have tried.
I tried flashing this back. E79, as the program degrader told me that block 0x57 was found at 0x3ff, i used a hex editor to cut and paste this block back in place, and replace the last block with fffffff..., like other good nand backups, this file also gives e79.
Then i tried this method (http://www.xboxhacker.net/index.php?topic=12265.0), and it gave me the 3rl and 0022. (tried with both the bad nand as a starting point, and the one i fixed with hex editor. both 0022.

Just so you know this worked fine for me with the first console i tried it on, and i have given this a go both with the 3 jtag wires and without them. with a reflash, xell always boots fine.

I also seem to be missing 3 lines of code in the decrypted kv.bin, at hex value ca0, the missing information is my osig, or dvd rom default type. (just thought this might help)

I wonder how much other data is missing throughout the nand.

Any help would be appreciated.

Thanks

Few things I need to mention:

Since we know that E79 means bad dashboard files, your box was working before you tried this and isn't now and XeLL did work for you, we can safely conclude that your copy of the original flash is badly dumped. As a fix I suggest:  (requires the CPU key which I believe you already have)

1- Remove R6T3
2- With Degraded 1.1 and the 1888 FS dump from the usual place build a fresh 1888 image for your motherboard using the corrupted flash as basis.
3- Flash it and see if everything work properly.
4- Update the console to the same version it had when you started (if it was at NXE use the newest pre NXE update you can)
5- replace R6T3

I don't see the console working on live again after that *suspicious* fix though.

thanks for the info, i did try the 1888 fix, but did not remove the r6t3 resistor, i shall give this a go, and let you know how it goes.

thanks for the help.

however, should i use the hex fixed nand, and a keyvault that has some osig info in it, or should i just use the original bad nand backup?

edit, doesnt matter, i shall give both a try.

ok just got  a xenon console today (traded a ps3 for it heh) used hellticks design to make jtag cable (thanks man) now the nand is dumping. cool thing is the unit came with 5787 dash on it. however i got 2 questions. if i only plan on using the box for linux is the removal of the rt63 resistor needed? i NEVER plan on playing games on this unit. my next question is after i flash xell how can i boot one of the linux livecds?

[sonic-iso]

ok nand dumped once no errors dumping 1 more time to compare

Not removing R6T3 might leave you with a weird/impossible fuse count. That would make the console unusable in XBOX live.
If you're going to keep it for homebrewn, removing it will do only good.

cool. dumped twice no errors everything checks out. now time for xell flash

Finished also the last test... Nothing to do... I have 14 dump and there're differences in all of them...

I can try to increase the cable lenght from 30cm to 1 meter?

I have done a lot of testing / dump... .Nothing to do Every dump is different from the others. I have changed 5 computers and changed all the available LPT port mode (Normal / ECP / Bi-Directional), the flashconfig is the right one on each test, 01198010, but I can't sort out the problem. I have got on each dump an error on the address 153 but I think is normal... Every dump the error is on the same address so I think is not a big problem...

Just for testing purpose I've add an LPT extension cable between the computer and the interface, but same result... There're differences between the dump...

Can help me to change these things :

- Move the Ground from the golden ring on the motherboard back to the J1D2 - Point 6
- Change the Eide cable that I have used for transport the signal with a better one
- Try to increase a little bit the lenght of the cable (now is 30 cm)
- Try to remove the connector that I've put in the middle
- Try to reduce the resistors on the LPT connector. Now I have 120 ohm instead of 100 ohm (I don't think the problem is here)

Please advice... Thanks

Would it be possible to use the Infectus in SPI Programmer or JTAG Programmer Mode in combination with NANDPro? I think , if its possible, only with some code changes to nandpro ?!

[sonic-iso]

hmm i dont understand why some people are having problems... i performed last night flawlessly. i made 3 dumps, after doing file compare on the files they ALL matched.i flashed xell than flashed to orig no problems. no errors nothing everything went smoothly. i used a 2002 model hp laptop as the computer. diode was used properly and as i mentioned in a earlier post. i used hellticks wiring method with the network cable method for wiring.

Just a question... Did you have some unreadable page in your nand?

I have got everytime the same error on the address 153... Maybe this's the problem of my nand differences.

Just for your information I have falcon m.b. basically I can only read the nand.... Maybe I can try to erase and write my backup but I need to be sure at 100% to get the right nand before trying something else...

Please reply to my question

[Hoax]

Hm I don't think so! You said the error occurs every time you try on exact the same block. Maybe your dump won't boot but thats no reason for differences in each dump.

Dumped my NAND (also falcon) three times where the first dump was on SPP mode, the other ones on bi-directional mode. Dump 2 and 3 matches 100% whereas dump 1 is different in some points cause it has 16 Bad Pages in it. Dump 2 and 3 got 0 BP. I think (or better hope) that dump 2 or 3 will work soon, if I'm able to try with my falcon. Until then I'll dump the NAND a few more times to be sure I tried every mode!

Did you turn the xbox on between the dumps? is there also a difference when you dump it two times in a row without powering it on ?
what sectors exactly differ? how many bad pages? is the empty pages count the same in each dump ? is the dump readable in the flashtool (can be opened without errors) ? tried different new/old computers/laptops ?

Cause your flashconfig is correct I guess the wires are all correct.

Thanks for the info

Did you turn the xbox on between the dumps?

All the dumps are made without powering on the xbox

Is there also a difference when you dump it two times in a row without powering it on ?

Yes, there're differences between two nand dumps without powering on the xbox

What sectors exactly differ?

Everytime the sectors are differents... but everytime are in a particular area where there are a lot of FF (Please check the picture below)

How many bad pages?

2 Pages at the same address everytime (Bad block at 0x576600 and Bad block at 0x576810)

Is the empty pages count the same in each dump ?

Yes, everytime 1488 empty pages

Is the dump readable in the flashtool (can be opened without errors) ?

Yes, I can open all the dump in flashtool without any errors. Without the Cpu key and 1BL, currently, I can see only the CB / CD / CE / Patch 0 / Patch 1 and on the right side of the utility a list of the files like aac.xexp2 / bootmain.xex / createprofile.xexp2 and so on

Tried different new/old computers/laptops ?

Yes, I have tried with 6 or 7 computers / laptops (old and new)

Cause your flashconfig is correct I guess the wires are all correct.

This's a good point. At least I have done the wires in the right way

Thanks for your help

- Try to reduce the resistors on the LPT connector. Now I have 120 ohm instead of 100 ohm (I don't think the problem is here)

You could lower the resistance, dont make it higher as it will have more problems reading the NAND correctly.

Could you make a printscreen of Nandpro2a's output?
