Need help!
I've got an N3 flight controller, which I connected to the Assistant software after several months. It got detected by the software, but did not allow me to access any of its parameters. I quickly realized that I have an old version of the A2 (V1.0.7) and immediately deleted it, and downloaded the latest one which is V2.0.0. This is as of August 14th, 2018. The N3 then got not only detected, but allowed me to switch between all the parameters like gains, PMU, GPS, LED, etc. It asked me for a PMU and LED upgrade which I attempted. PMU upgrade failed, and then I tried LED upgrade. It failed at 99% and then gave a message "Lost connection to MC". Ever since, the N3 is not detected by the A2 assistant.

Earlier, each time I powered up the N3, the LED used to cycle through all the colors and then end up with 3 yellow blinks, as if in Atti mode. Ever since the firmware upgrade failure, it is now blinking just white, every 2 seconds. PMU is blinking blue and GPS is blinking red. Tried different cables, both Windows and Mac, and reinstalled A2 Assistant couple of times. Absolute symptoms of the Flight controller becoming bricked. Out of ideas now.

Sorry, by A2, I meant to say "Assistant 2 for Autopilots" and not confuse with A2 software or A2 flight controller.

Try again. There are new updates.
Best regards,
Wilhelm

DJI Assistant 2 For Autopilot v 2.0.0

https://www.dji.com/n3/info#downloads

Do not install multi Assistants.

Uninstall all, then install v 2.0.0

After upgrade perform a factory reset: dashboard, restore.

Did not work. I have the latest assistant software version.

Also, no explanation of blinking white LED on the N3 anywhere on the internet.

google and try NAZA hard reset.

I am seeking help from this forum as a result of not getting help from multiple sources. DJI email support did not help me after a chain of 15 email conversations. 5 other N3 owners were clueless with the symptoms my N3 has. Please do not assume I did not google out every possible solution.

Kindly guide me the steps of how to hard reset an N3 flight controller without any software support since it does not get recognized on the Assistant 2. Thank you!

Usually DJI FC become hard reset by connecting F1 and F2 with a patch cable and then power on the FC.

Обычно DJI FC становится жестким, подключая F1 и F2 с помощью патч-кабеля, а затем включите FC.

A3 to do a reset? After installing the jumper F1 and F2 to supply power?

Hi,
I have an n3-ag flighcontroller and now I can't use it.
Because I can not detect the voltage level in flighcontroller and my pmu led is red.
I used 12s 48v battery.
