Downgrading firmware on P3P from 1.10.9 to 1.7.6

how to make file "P3X_FW_DEBUG" to force downgrade

I rolled back from 1.11 to 1.7 too with debug method. Can confirm it is working for me. I'm having the board P01012.09 .
I did it like:
1.11 -> 1.10 + Debug
1.10 -> 1.9 + Debug
1.9 -> 1.8
1.8 -> 1.8 + Debug
1.8 -> 1.7
1.7 -> 1.7 + Debug
The last step was important for me, every version step was fine without a + except for 1.8 -> 1.7. There I had to use again debug method on 1.7 itself otherwise I got a + .

EDIT: I have to say that I did the update from 1.10 to 1.11 within the day the update was released the first time on 06.07.2017. And the downgrade was done within the next two days. I don't know whether DJI modified 1.11 to prevent downgrading. I attached the 1.11 I downloaded at 06:30PM at the release day and which I used to upgrade. LINK

On your computer, create a txt file with nothing inside it and then rename it.

Or download from here digdat0/P3I1_FWProject

Hello,

Can somebody tell me why in my log file, the versions checking start with module 400 ? For any other log files starting with 305,306.

Order doesn't matter.

And why - because this is how DJI programmed it. The order probably depends on order of responses from modules.

I have now succesfully downgraded my bird P3P from 1.11.30 -> 1.11.20 -> 1.10.9. In summer I got ESC error and updated to 1.11.30 and managed to fly again, but now when I tried again the error came back. So with fear I had to try and succeeded to downgrade. Thanks for instructions!
