Hello!
Anybody could me post firmware for 4K which is older than latest?I don t  know exactly with which firmware number,but previously than 1.5.4 I  reached 1427 m distance without returning to bad signal or anybody can  you give advice how to downgrade it?                                                

The previous version should be on your computer under downloads unless you manually deleted it.  Good luck

From the main home page, if you press the graduation hat (upper right corner) and press it for 5-10 seconds then let go, it will take you into the downgrade menu.
