Default [Q] Accessing Diag Mode from Android Revolution HD

I am trying to extract my MSL from my Sprint HTC One using CDMA Workshop. Have installed Android Revolution HD 31.6, which is running Android 4.3. Have phone rooted, S-Off, TWRP installed. Since AR is Sense based, it should work with the HTC special codes, but when I enter ##3424#, nothing happens. It resets the input in the keypad same as if I had entered an invalid # code. ##3287# and ##778# work, but are not especially useful without the MSL. I would call Sprint, but I try to avoid human interaction whenever possible. Is it possible to access diag mode from AR or do I need a stock ROM for this?
