I accidently deleted some pictures from my galaxy s3. I looked online to see if I could recover them, well apparently something went horribly wrong. I am now stuck with the "firmware upgrade encountered and issue" on my screen. I downloaded Kies and put in my model number which was fine. I've been trying to find my serial number for the last hour and a half and everyone I input is wrong. Is there a way for me to get my serial number somewhere or to get my phone to actually work again. Mind you my service provider is metro pcs, so I don't know if that also affect where my serial number might be located.
