I have a Jtag Xbox that I no longer have the external HD for which had everything on it. I need to reset my entire system so I can start fresh with all the latest xex menu updates etc. I have a new HD ready to use. I don't know the nand. Anyone that can help me would be great!
You can load XEX Menu from a burned ISO or from a USB drive, download: XEX Menu Once you have XEX Menu working you can dump your current hacked nand and update by following this tutorial: Xbox 360 Jtag or RGH Hack Easy Update to Dashboard / Kernel 17349 with XeBuild GUI Finally to prepar another hard drive to use with the 360 this is the tutorial you want: Upgrade a Jtagged Xbox 360's hard drive, restore the avatars and Xbox 1 emulator. That should hopefully get you started.
That is exactly what I was looking for thank you!! My next problem is I bought this a few years back off a guy and didn't get a copy of the nand and I can't figure out my cpu key.. I tried some startup that was suppose to tell you but it was just blank where those number were suppose to be.
That's all explained in my tutorial on how to update to dashboard 17349, read the part in thats called "How to findout my consoles CPU key".
