Installed the core and 57mm butterfly display today. Upgrade to 2.79 went smooth. Tried to upgrade the butterfly display to 3.01 from the core. Negative on the butterfly upgrade. The release notes say it does update from the core. I could not find any special procedures. The website says version 2..8 should also upgrade the butterfly directly from core.. so maybe the next release. Antenna's mounted on glare shield of V2. Let me know if anyone wants some pics installation.

I recently upgraded with 2.79 with no problems - to 3.1. One thing that is different in the release notes - mine took about 10 minutes, once it was "loading" (it seemed longer).

From the release notes CL31_en.pdf:

Butterfly firmware/FlarmNET update on Co
1. Copy Butterfly firmware (.bfw) and/or flarmnet (.bfn) to a USB stick.
2. Connect stick to Core.
3. Switch on system with BF display knob pressed.
4. Verify BF display goes into UPDATE MODE with 'WAITING', then 'LOADING'.
5. Wait until BF display restarts (can take up to two minutes).

I only put the .bfw file in the top level of my USB stick - no flarm config, no .bfn file... then I did the .bfn flarmnet separately, after I moved the .bfw to a file folder within the USB stick.

I had good luck doing each update - Brick, then display, then flarmnet separately.

Good luck - the better fonts on the Butterfly display make it better.
