    [MEGATHREAD] "Failed to update software. Use SKT USIM card to update."

    Can't update my phone because I keep getting this message, "Failed to update software. Use SKT USIM card to update." How do I get around this or where can I get this card? I bought a Samsung Galaxy S4 Advanced (SHV-E330S) on Ebay from Korea.
