Hello,

The version flashed is 2.4.2. The héli fly very well, but the fbl system is not recognize. I can't change any parameter. No blue light on the "cable".
I changed the cable ( I have 6 spirit) and it's the same thing.
Impossible to be recognize.

Hello,

please check this guide:

2 How to revive the unit
Connect the USB interface to your PC and the unit (SYS port).
I suppose with battery connected ?
Start the software. Select NO when prompted for Demo mode.
Go to the Update tab and select firmware you want to flash (4df file extension).
Press the Flash button (and then OK) - you should see "Recovery mode" label in the software.
Power up the unit (from your BEC or a battery). Immediately after power up, flashing should start.
In 20 seconds, unit should be operating again without any issue. Your settings are untouched.

No, you have to connect battery at the step: Power up the unit (from your BEC or a battery).

ok, it's clear, thank'a so much

OK, I flashed the 2.4.3 version with recovery mode. All OK. The heli is good but again not recognize on my PC and MAC...
Perhaps the cable, I can try again an other ...No blue light on the cable when it is on the heli (but not on PC).
It's the 2 em cable I try, I have other (I have 6 spirit) but it's very strange..

edit
OK I tried with an other cable, the same. I tried with an other heli (oxy3), the same. I tried on both my mac or PC (windows 7), the same .
Perhaps a driver problem on my PC or Mac...I don't know..

edit
OK I think it's my fault.
before
put battery on heli and connect the link on heli and mac and switch the soft on mac: nothing

after
put the link in first on heli and mac, put the battery on heli and switch the soft on mac : ok recognize

strange because before I think the first metod was ok.

Great news!

Yes, it is always needed to start the unit, wait for initialization and then start the software.
You can find the procedure described in the manual in a greater details.
