Got it thank you. Here are steps:
1. Use DfuSe Upgrage Tool and Upgrade (Devo7E v2 latest or stock firmware goto to www.walkera\upload\radio\devo7e and download devo7e.zip).
2. After updating back to Devo Firmware, run updates on Library.
I thought it didn't work because when I boot up the TX it stuck on window "Throttle Stick". Then I realized that the walkera firmware always flash back to mode 1 and naturally my right stick is at midstick. I push down the right stick and Devo software comes up. I go and change stick mode to mode 2.
Now I can go back to Devo 7E if needed. I really like Dexiation but can't get my Ladybird to get to 3-axis.
