This is a tale of praise for this Tutorial/Method and a word of caution on using other methods. This method worked perfectly on my two RGH Xbox 360s. However, I got a little greedy and wanted to update to 16756. I tried to do this on my own, without this idiot proof guide, using Xebuild. On the first (and only) try, things went very wrong. It wouldn't even boot into Xell. There are no real tutorial/guides that I could find that tell you exactly how to recover from a bad flash if it doesn't boot to Xell. I think they all assume you did the original RGH and would know how to "reflash the Nand". However, I didn't, I had the RGH done by someone else. So if you are basicly a RGH/JTAG Noob, stick with Begallegal1's method for updating. This is the second dash update that Begallegal1 did and both have worked perfectly. However, if you are a little greedy, and screw things up, here are the basic steps I took to get my Xbox working again: 1. Get the following: a. Nand Programmer (like Matrix, 360 Nand Flasher or Nand-X). b. Nand Drivers (Nand-X or Maximus seem to have generic drivers that worked on my Matrix) c. The image_00000000.ecc and updflash.bin files from the original RGH/JTagging (hopefully you got these from the guy who did your Xbox). d. A tutorial for RGH/Jtagging the Xbox that uses NandPro to write the files (because, from what I've read, NandPro seems to work when others might not). e. NandPro (versions 2e and/or 3 seem to work). 2. Use the tutorial(s) you got, install the Nand Programmer hardware (this assumes the guy who did your RGH/JTag removed it). 3. Power the programmer by only plugging in the Xbox (do NOT turn on) and plugging in the USB cable to the computer. 4. Install the Nand drivers. 5. Using NandPro, test the Nand Programmer by seeing if it will read the Nand. 6. Using NanndPro, write the image_00000000.ecc file to Nand. 7. Unplug the USB and test to see that the Xbox boots to Xell. 8, Put updflash.bin on a USB drive and plug into Xbox. 9. Reboot Xbox into Xell and it will flash the Nand with updflash.bin. The Xbox should be back to normal (at least mine was). If you have questions, I almost certainly will not be able to help. For instance, the tutorials indicate ways to prepare a new image_00000000.ecc file and probably any updflash.bin file you have will work (like a backup made from Simple 360 NAND Flasher). However, my actual experience only consists of the above steps and I post them here for fellow Noobs that mistakenly venture beyond the outstanding guidance that Begallegal1 has provided.
