Xbox 360:Standard NAND

This guide will walk you through obtaining NAND dumps, creating a patched dump, and writing it to the console using a NAND-X, JR Programmer, Matrix Flasher, or xFlasher 360. Although JR Programmer clones may work, you might want to check if your JR Programmer is a clone in case you expected an original and received a clone.

This guide applies to all motherboards except 4GB Corona motherboards.

Equipment Needed

* A NAND-X, JR Programmer, Matrix Flasher, or xFlasher 360 * A mini-USB to USB cable * A soldering iron, solder, and flux * Isopropyl alcohol (90% or higher recommended) and cotton swabs * 28AWG or 30AWG wire

Installing Drivers

1. Download and extract J-Runner with Extras.
2. Press Win+R and type devmgmt.msc and press Enter to open Device Manager. You can also get to it by searching for it in the Start menu. Plug the USB cable into both your programmer and your PC. Windows should find it and it will appear as J-R PROGRAMMER or NAND-X or two USB Serial Port entries under the “Other Devices” category in Device Manager.
3. Install drivers:
   • (xFlasher): Launch J-Runner with Extras, plug in your xFlasher, and click the xFlasher menu and “Install Drivers”.
   • (JR Programmer / NAND-X / Matrix): If you are on Windows 10, you will need to disable signed driver enforcement. Once done, right-click the programmer’s name in Device Manager and select Update Driver Software… > Browse my computer for driver software > Browse… > navigate to your JRunner folder > common > drivers > OK > Next. You may receive a popup saying that Windows can’t verify the publisher of the driver, select the option to install it anyway. It should successfully install and file your device under its own category in Device Manager. Your programmer’s LED light should also turn green.

Soldering to the Motherboard

xFlasher / JR Programmer / NAND-X

1. Your kit will come with a cable with a white plug on one end and open wires on the other. Solder each wire according to the diagram below. Note that the wire colors may be different than the picture below in a knockoff kit, so go off of the wire position and not the color of the wires in that case.
   

1. Once you’ve finished soldering, clean up any flux with isopropyl alcohol and cotton swabs.

Matrix

1. Solder a wire to each of the labelled pads on the Matrix and to the corresponding pads marked J1D2/J2B1 (phat) or J2C1/J2C2 (slim) on the motherboard in the diagram below.
   

1. Once you’ve finished soldering, clean up any flux with isopropyl alcohol and cotton swabs.

(Corona Only) Solder Bridges

Ensure to check these resistors and solder as noted.

Reading the NAND

1. Plug your Xbox 360 power supply in, but do not turn the console on.
   • If you are using an xFlasher, set the switch to SPI.
2. Plug the white end of the cable into the bottom port of the programmer. Plug the mini-USB cable into the programmer and your PC.

3. Launch JRunner. Select “Read Nand” in the top left. It may prompt you for your Xbox 360’s model, make the correct selection and click OK. If everything is wired properly, it will read your NAND twice and automatically compare the dumps. If it says “Device Not Found” or anything about missing CB/CD files, see the troubleshooting steps at the bottom of this page. If you get messages about bad blocks, ignore them. When it has finished, it will tell you if the two dumps are an exact match. If they are, you can close JRunner and proceed. If they aren’t, take more dumps until you get matching ones.
4. Copy one of the dumps to a safe place such as cloud storage or send it to yourself in an email to keep it safe. They are located in the output folder in the J-Runner directory.

Writing New NAND Image

1. In J-Runner, select “…” next to the Source File field and choose your nanddump1.bin. In the top right of the window, select the latest the dashboard version in the dropdown menu next to “Dash Version”.
   • If you want to add a dashboard, extract it to the XeBuild folder inside your JRunner directory, and restart JRunner.
2. Select the appropriate radio button in the top right of the window:

• Glitch - For RGH1
• Glitch2 - For RGH1.2, RGH2, and S-RGH
• Glitch2m - For RGH1.2, RGH2, and S-RGH if your eFuses are in a non-bootable state.

Put a check in the appropriate check box (if applicable) in the top right of the window:

Model	RGH1.2	RGH2	RGH2+	S-RGH
Zephyr	-	SMC+^1	-	-
Falcon	SMC+	SMC+^1	CR4	-
Jasper	SMC+	CR4^2	CR4	SMC+
Trinity	-	CR4^2	CR4	SMC+
Corona	-	CR4^2	CR4	SMC+

^1 X360ACE chips only

^2 CR3/CR4 and X360ACE chips only

1. Select the “Create ECC” button and wait for it to finish.
2. Select the “Write ECC” button and select your system and press OK. It will write the modified NAND dump to the motherboard.
   • If it says “Device Not Found” or Flash Config 0x00000000, see the troubleshooting steps at the bottom of this page.
3. Once it has successfully written to the motherboard, unplug the power cable from your Xbox 360 and unplug the USB cable from the computer and programmer.
4. Go back to the RGH Hack page and continue at the start of the Xbox 360:RGH.

Troubleshooting

• “Device Not Found”
  • Re-insert the USB cable
  • Check that the drivers are properly installed
• “Flash Config 0x00000000”
  • Check that your power brick is plugged in, with an amber colored LED, and that it is plugged into your console completely (console turned off).
  • Check your soldering to your motherboard. Each point should be solidly connected and have a shiny round joint.
  • Check that you’ve cleaned up any flux you had used. Depending on the type, it may be conductive and cause issues. MG 835 is strongly suggested to avoid this.
• “Wrong Version”
  • Re-insert the USB cable
• What should I do if I ripped off a soldering pad?
  • Look online for an alternate point to solder onto. Practice more on junk electronics before attempting to continue.
