XeBuild GUI

If you are using a modded Xbox 360, then you surely discovered that it can be quite a hassle to find an application that can help you update your customized kernel.
XeBuild GUI is one of the utilities that can come in handy in this situation, especially since if you take the time to analyze all the provided options and ensure your update is successful.

A fully-featured GUI for experts

Although the graphic interface is meant to be as straightforward as possible, since all the functions are neatly organized and presented, it still needs to be mentioned that XeBuild GUI is created mainly for experts.
For instance, you require advanced computer skills in order to dump your device’s NAND and to get the CPUKey required to proceed to the next steps in updating the Xbox 360 dashboard.

Follow all the specified steps to efficiently update the Xbox 360 kernel

Once the previous stages have been completed (dumping the NAND and specifying the CPUKey), you can move on to other steps that are equally important in this process.
You need to choose the destination folder as well as to specify the build type and motherboard that you work with - i.e., assuming these have not been automatically recognized from the source NAND you loaded.
Also, if you switch the GUI to the advanced mode, you get to personalize even more settings, such as the options related to xeBuild (like the game or DVD regions, MAC address and video mode).

Update the dashboard of a modded Xbox 360

If you are not sure about the configuration you created, it is best to spend some time with the research, otherwise you might end up with a corrupt NAND that does not work on your device.
On the other hand, you also need to keep in mind that modding your Xbox 360 is not a practice encouraged by Microsoft and that is should only be performed by experts.
