[Sk8r4life]

Hello all. I have a UN50M5300AFXZA Tizen 1401.1 OS. I don't have the factory remote but i can access the service menu. Im not seeing Wiselink anywhere! Looking to Mod Firmware through USB. I've tried access through PuTTy Telnet...No Luck! If I switch USB Serial to "on" will it recognize laptop for CLi ? Help Please!
