I just tried this on my Samsung Galaxy Appeal 2.3.6. First, I didn't know what it wanted by "Select 'FRODO' or 'ARAGORN' or 'LEGOLAS' on your device". If something was supposed to come up on my phone screen I didn't see it. So, I just clicked OK. Finally at the end it did 4 reboots and just stopped.
