When it finishes, you’ll be presented with this
  • Hit any button on your controller, and when you’re back at the Dash, take out the USB Drive.

Backup the flashdmp.bin in case you need to flash back!

  • Download and Extract XeBuild 17544.
  • Open the file named XeBuild GUI 2.0.
  • On the top of XeBuild, to the right of Source File – Hit Open and select the file “flashdmp.bin”.
  • If you have a 4GB Corona (48mb Nand) it’ll give you this error
Hit Yes.
  • A little bit under that same spot, you’ll see Keys.
  • Next to the text box of CPUKey, hit the button “Get CPUKey from Keys.txt”.
  • Select the file “cpukey.txt” that Simple 360 Nand Flasher made
  • Double Check the Build Type!!
  • If you have a Slim Trinity or Corona, it’ll be Freeboot (RGH 2.0).
  • If you have a Phat, you need to know whether it’s RGH 1 or 2.
  • If you’re unsure, Dashlaunch will tell you in the bottom right.
  • Always select Freeboot, not ECC.
  • The last thing needed to do, is to select the 17559 Kernel.
  • It should be auto selected, but if it’s not:

Please make sure all boxes on the bottom are Checked:

  • If you’re on a 4GB Corona, this step is very important.
  • You NEED to enable ‘Open Parameter/Argument Editor‘:

  • If you get an error saying it cannot find files, hit Yes.
  • After it 100% Downloads, hit Generate Hacked image again.
  • If you get an error message that says this:
  • Then double check your build type again.
  • If you are 100% positive that you selected the correct one, then hit No.
  • Then it’ll bring up another Popup asking if you’re sure you wanna use it, hit Yes.
  • If you have a 4GB Corona, you’ll be presented with the same error you had earlier.
  • The only difference is, you’ll get a Popup that looks like this:
  • All you’re going to do, is add 4g to the end of Corona like this:
  • Then, just hit Save the New Parameter.
  • In the Right window of XeBuild, if all is successful you’ll see a Log that looks like this:
  • Go to the Output path, where XeBuild saved the file, and you’ll see the file “updflash.bin“.
  • Drag that updflash.bin into the Simple 360 NAND Flasher folder on your USB.
  • Once moved, take the USB, and put it into the Console.
  • Go to Xex Menu and start the Default.xex for Simple 360 NAND Flasher.
  • Once it is loaded, hit A to Write Your Nand.
  • Then hit Start to confirm the Write to your Nand.

  • Rebooting in 5….4….3….2….1…. and then the console will automatically reboot.
