hey guys i got this to work on my TP and i think the problem you all are having is because of the .cab file being for a Diamond, not a TP.
i went into the file using total commander and made the edits and it worked perfectly. just remember to do a soft reset so the changes take effect.
here are the steps i used for this:
1) open total commander (or other file editing program) and go to the windows folder
2) scroll down and locate the file "26948339_manila", highlight it and select "edit" from the file menu
3) scroll down within the file until you locate the line that says:
<Page Order="5" Name="music.page" PackageName="HTC" Title="[[IDS_MUSICTITLE]]" ExternalScriptPath="HTC\Scripts\sprintmusic.luac">
(note that on the XDA site, the code says "Page Order "4"....")
4) delete this part of the code only: ExternalScriptPath="HTC\Scripts\sprintmusic.luac"
(make sure that this is the only thing you delete)
5) select "save" under the file menu, exit the program and soft reset...that should do it.
hope this helps....im not a programmer but i follow directions well and not too afraid to get my hand durty, lol.
