here is no 3012 or 3013 firmwares. The latest before 3014 is 3011
1. Your TV doesn`t accept any firmware extept higher one (3015?)
2. We have the "zero firmware" to make downgrades, search on forum for 0000.0 or "zero firmware"
3. It is your game - to test all firmwares released ever for your TV, or do you expect some "improovements" from older firmwares?
