i cant think of anything since the phone has such a small amount of support (as you can see from all the chimes lol) i doubt anyone can solve this problem seems like you bricked it some how so try factory resetting it, here's a link to do that
http://support.sprint.com/support/t...Reset_via_Hardware_MOTOROLA_ADMIRAL/26293-396
if that doesnt work try registering your phone to motorola they dont ask for receipt or proof or purchase just say it was a gift, once it asks for purchase date make it a few weeks ago and then you'll have a year from your "purchase date" to mail in your phone if you encounter a problem, you only pay for shipping.
lastly if you have insurance on your phone you can call sprint and tell them that the phone broke on its own its a internal problem and insurance covers that and they have to send you another phone free of charge and you will send that one back
hope one of these solutions help, if you have a questions PM me cause im barley ever in this section
