So I've been trying to update my S2X to Jelly Bean and Kies says that "Your device's current firmware version is not supported to update firmware via Kies". Kies is updated to the most recent version. It tells me my phone's current firmware version is PDA:LG2 / PHONE:LG2 / CSC:LG2 (TLS). I really want the update and this is beyond frustrating. I'm not really tech savvy and would like to avoid rooting or using Odin. Can someone please tell me what the issue is and how I can fix it?
