well i guess bottom line is if it doesn't specify its for your device specifically
Dont Risk It! Call me paranoid but being a skeptic with such situations is better than being too curious and daring lol. anyways yea theres two options for ya.listen up carefully.
you guys can go ahead and file a claim with metro guard and pay the $130 deductible or since this device is less than a year old we still all have a 1 year warranty from samsung so u can call their tech support and they will have you try certain trouble shooting methods which has been mentioned here already but just play along lol once they see theres no turning back on they will send u a prepaid postage for you to send them your bricked phone and they will mess with it and eventually fix it via jtag. only issue is doing it with the samsung warranty means you will be without a phone for quite some time if i remember correctly i got a samsung indulge back in 3 weeks, so yea best to be patient but hey fixed for free and u cant complain lol.
metro guard: Pro- they can over night you a new phone and you will get it next business day. con- cost $130
samsung 1 year warranty: pro- fixed for free. con- gotta wait a long time
hopes this helps.
