Yes I did, as I said one esc works perfect with both soft version 1.4 and 3.3, but the other one works only with softwere ver 1.4, i've done the updating process and reset properly. I repeated this 3 times but i gave up.

The one that doesn't work with soft 3.3 i have received from LRP on warranty after i had burned my earlier flow esc, it's almost unused.
