Xenon JTAG FreeBoot Install/Update 12611 If you are like me and tried every program and way to update or jtag your Xbox 360 to new dash 12611 and had no success. All I would receive is a black screen. Xbox booted up fine but then it just sat there. Hopefully I can help with some of this. All props go to ChaosChief as he showed me the way. I hope this helps somebody out there. You must have: • Your original nand with CPU key • Flash360 • XeXMenu • Usb Stick • Easy FreeBoot For updating your 9199 freeboot image: First you want to still have your Xbox flashed with the freeboot 9199 image. If you were like me and returned it to stock and tried rejtagging it and it still didn’t work, then you will want to reinstall your 9199 freeboot image. Once that image is flashed your xbox should be working fine. Go to step 2. For fresh JTAG install (not update): You need to jtag your console with the 9199 freeboot image. I used Jtag Tool 2.01 as its easy to use and uses 9199 dash. Make sure its not the new Jtag Tool. Now just follow all these instructions and completely write the 9199 freeboot image. You DO want 9199 freeboot image on your xbox and working. After you complete this, your Xbox should be working, jtagged, and have 9199 dash. Go to step 2. 2. Now using Easy Freeboot 12611 GUI click “create image.” Once the dialog box pops up, you select your original/stock nand. After you select the nand, a box opens to enter your CPU key. After you enter your CPU key, Easy Freeboot will open 2 command prompt windows and after each one you simply hit “enter.” Once done it will ask you to save your new 12611 image. 3. Once you have your new 12611 image named “updflash.bin” you want to transfer that and flash360 onto the root of your USB stick and insert that into your Xbox USB port. Start your xbox and go into XexMenu . Once in XexMenu, select flash360.xex and it will start. 4. You want to follow all dialogs to write “updflash.bin” to the nand. It will ask if you want to write keeping your current KV and Config or write without keeping your KV and Config. You MUST write KEEPING your current KV and Config. At one point it also stated that my KV was zeropaired and asked if I wanted to continue, you just select continue. Let Flash360 do its thing and follow all the on screen instructions to finish the flash and after it will shutdown automatically. DO NOT shut it down. Now remove the USB drive once the console shuts down and power back on your Xbox. BRAVO! You should have a jtagged console on 12611 Dashboard. Please feel free to give any feedback. I only tested with using the original nand and did not experiment with creating the 12611 image from the 9199 freeboot or from a dump of the current nand. It very well might be possible to use either of those.
