My Xbox 360 Doesn't Turn On Anymore Options

[Farid]

My Xbox 360 just doesn't turn on anymore; it seems it is dead completely!

My Xbox 360 specs :
Jusper
512MB Nand
Manufactured Date : 2009/08/11

The story beyond it went like this :
About one year ago I lost my DVD Key during LT Plus update.
Two weeks ago I wanted to recover my DVD Key with new RGH method.
I started investigating and found out I can dump my nand by USB and LPT.
I build a USB SPI flasher and dumped my nand three times. All of them are identical (they are 553,648,128 bytes)
Unfortunately every time I got some errors from 74A0 to 74A7.
I decided to use LPT method, but same errors came up for that addresses.
Then I updated my dashboard from 12611 to 12625 and then used USB method to dump my nand, but this time I got a lot of errors! (I think that, at this stage I had messed up my nand)
After a lot of works I pushed power button but my Xbox 360 didn't turn on!
I used LPT method to dump my nand again but it also gave me a lot of errors.
I wanted to write my first dump but after a little search on the net I found out this is considered as a downgrade and it mess with something called efuse, so I decided to ask here before doing further destruction!

Now I appreciate anyone who can help me to continue my work!
Thanks in advance

When I update the dashboard I didn't connect the fans. After updating successfully a massage pop up stating that XBOX console is designed in a way to turn off automatically if the CPU gets too much hot! I just ignored the massage and turn off my console.

Can someone tell me which part of nand changes after dashboard update? Maybe I can dump my damaged nand to some extent and mix it with my pervious good nand and use it :
Also which file is containing the DVD Key?

ok first make sure you have a good ground connection as that can cause issues reading and writing your nand

now to get your console back up and running is gonna take some work

open cmd and get to the nandpro folder with your original dump run this command

nandpro originaldump.bin: -r64 nanddump.bin

download multibuilder 0.3

place just your nanddump.bin into the my360 folder and click the run command to build the ecc for a 512 jasper

now copy the generated ecc to your nand pro folder and run this command

nandpro usb: +w64 image_00000000.ecc

install the RGH chip and make sure xell boots

now write down your CPU key

go back to the multibuild 0.3 my 360 folder and create a txt file named cpukey copy the key (all in caps)into the file and save

double click run and select 512 jasper again wait for ggbuild to finish DO NOT CLOSE the window write down the cfldv #


go back to my360 folder and open the file named options_r.ini look for cfldv= now take the number you wrote down and add 1 so if it was 3 your should have something that says cfldv=4

save and double click the run command one last time select 512 jasper when ggbuild finnishes it should refect the +1 cflvd you told it to use now use rawflash v3 to flash the image and hopefully if all went well you should have a RGHed 360

Is this command in correct format, NO lpt: or usb:, it seems strange :

CODE

nandpro originaldump.bin: -r64 nanddump.bin

****************************************

I read a bit of my current nand with this command :

CODE

NandPro.exe lpt: -r1 microsoft.bin 0 1

I opened it with HxD (Hexeditor), it is full of nothing! All I got is FF.

Last offset of this file is 4200h with 16,896 bytes size.

I opened my previous good dump with HxD and extract 16,896 bytes from its beginning. I named it microsoftw.bin then I wrote it to my nand with this command :

CODE

NandPro.exe lpt: -w1 microsoftw.bin 0 1

Now I can turn on my Xbox but it won't boot and after blinking green light, it gives me three red lights!

Conclusion : I have lost the nand of current dashboard (12625) but still I have a good dump of nand from the previous dashboard (12611)

Please someone answer these questions :
1. Which file of nand contains DVD Key?
2. Which file changes after dashboard update?
3. Now I have to rely on RGH to run the games, right?
4. Can I return my Xbox to its original state after doing RGH successfully?
Thanks in advance

ok to answer your ?s yes that command is formatted properly it would tell nandpro to mount your 12611 nand image and read the first 64mb of it to a file named nanddump.bin

as for your other ?s
1. the kv contains your dvd key (block 1 of your nand)
2.it depends on the dash update but alot of things are changed from dash to dash
3.and 4. i can answer together you should be able to do either..you can use the RGH or use a donor nand to make a stock nand image for the console

Well reading the entire thread it doesn't say you flashed your image yet. Also your going to need your console updated to a newer dash. Think the one that most tools are using is 13604 for the rgh.

you actually don't need it updated i have glitched 8955 original dash consoles to 13604 without an issue

OK, thanks for the help. Now I have my CPU and DVD Key. Please help me to make a retail dashboard of 12625. I couldn't make it with xeBuild-GUI-2.01. It gives me error on 12625 but I could make a retail dashboard of 14719.
