This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.
I told you not to drink and root.
