If you want to post the actual command xml that you have tried we can try to spot any errors.  Otherwise we are just playing pin the tail on the donkey.  Except it is a lot less fun.

I tried both script, same result.

<?xml version="1.0" encoding="utf-16"?>

Try replacing the original iPhonePager.py file with the attached.

same thing 

for the device number, do i start from 0 then 1 and 2 and so on until it works?

I don't know, as that is Haddood's implementation, not mine. But it doesn't matter since the script no longer works.

I suspect it's because Apple has made some changes: http://thenextweb.com/apple/2014/09/01/this-could-be-the-apple-icloud-flaw-that-led-to-celebrity-photos-being-leaked/

Yea that's what I thought too 

At least people would now know this no longer works.

So thanks anyway.

If it's an important function for Apple people, someone could try posting an issue for the script developers at GitHub (link in the first post) to ask if the script works for them, and if not, if any updates are planned/possible.

EDIT: Based on the fact that even the official Apple Find My IPhone app only works on machines with iOS 8.0 or later, I think people can safely give up on the idea. https://itunes.apple.com/ca/app/find-my-iphone/id376101648?mt=8

I confirm the script stopped working a while ago, I thought it was on my side and never had the time to debug.  may be nime5ter is right and it is linked to leak happened ... so for the time being this is on hold till things get solved

P.S. I did not put a link in the Gems forum, since was not sure if this still works ... I will update the first post to warn users ...
