Just an FYI for PPCKitchen users.
If you want your Build ID to show up properly in Device information and in the RUU screen when flashing a new ROM, create a PROVXML in the following format. Replace "BuildID" with whatever you want to show up in device information.
You can create a PROVXML by going to <\BuildOS\TOOLS\OEMizer.exe> and fill in your information. The first screen will be the information that shows up in your <Option.xml>. Then on the left side of the windows, put a check in "PROVXML" then click on "PROVXML" and fill in the box. Remember that in OEMizer, "<wap-provisioningdoc>" and "</wap-provisioningdoc>" are already entered for you, so you don't have to type that in in OEMizer.
Code:
<wap-provisioningdoc>
<characteristic type="Registry">
<characteristic type="HKLM\Software\OEM" translation="filesystem">
<parm name="ROMVersion" datatype="string" value="BuildID" />
</characteristic>
<characteristic>
</wap-provisioningdoc>
This entry is verified to work on the Titan and should work on most other devices as well.
