How To Recover From A Bad Nand Flash (Dead 360)

I realized that a lot of people are having issues with their xbox's not powering on. Use this guide to recover your nand. I did not write this tutorial and I take no credit for it.

I didn't see a post for this anywhere on 7s.

Ok if you have tried the jtag hack and have been unsuccessful (Xbox wont turn on at all and "Cannot detect a flash controller" in Nandpro) do not panic there is salvation.

You can recover from this Hell by shorting out the nand there is two methods on how to do this and both accomplish the same thing. The first method is the one that is most recommended but is a bit more difficult to do. what you want to do is short out pins 44 and 47 by connecting them with a piece of wire (or anything conductive ex: screwdriver or pin)


METHOD 1

SHORTING OUT PINS 44-47

Here is a detailed diagram I have made showing the pin outs on the nand so you know which pins you need to connect together to short it out.




The procedure for causing the short is the same for both methods and will be reviewed below





METHOD 2

NOW THE SECOND METHOD IS A LOT EASIER BUT IS ALSO MUCH MORE LIKELY TO CAUSE DAMAGE TO YOUR 360. USE AT OWN RISK!!!!!

This method involves getting a piece of stripped wire and laying it across all of the legs of the nand at once. Thus causing a short and forcing the nand into a recovery mode where you can than erase or rewrite it. below is another pic i have edited to show you what i did.




*Note the wire can be held in place with your index finger on one side and your middle finger on the other while doing the procedure.


PROCEDURE

This procedure works for both methods but i am going to demonstrate Method 2 because it is easier to execute and illistrate



Disconnect all cables from your console. Reconnect the video cable and get your wire in place on the nand.

Pic Below









Now while still holding the wire in place with your finger reconnect the power cable to the board

This is what everything should look like






Now remove the wire carefully not to touch anything on the board. (best method is to just let go of it and pick it up after.) check your xbox 360's power bar if the light has stayed orange than you should be fine if it turned red than the surge protect has kicked in and you need to repeat the procedure.

Now open the command prompt and go into nandpro and test reading from the nand.

ex: C:\nandpro\nandpro lpt: -r16 test.bin 1 1

this command will attempt to dump your keyvault if you get a flash config and it succeeds than your nand is able to read and write again.

* At this point i would suggest erasing the nand (ONLY DO THIS IF YOU HAVE PROPER BACKUPS OF YOUR NAND)

To erase the nand go in to the nandpro directory ex: C:\Nandpro\ and type type: nandpro lpt: -e16 0 400

This will completly erase the nand than just flash your original back or the proper version of XBR (If you flash your original back you must remove the jtag wires or the console will not boot)

Your Xbox 360 should now be alive once again.
