Hi guys

I have littlebee 20a a , with betaflight.
There was working fine, i have already flashed them with blheli 14.3 .
Now, i wanted to activate damped light, so i opened blheli 14.4 and i see "erase or unknow firmware"


so i tried flash them to last blheli version, and then flash failed, adn i got this error messages :






and now , when i power up the quad, the esc get into boot loop.

HEEELPP !

what can i do now ?

Am I correct in thinking you are flashing all the ESC's at once?

Have you thought about doing each ESC individually and see how that goes.

Yes i first tried flash all in once, then, everything failed I tried one but one
