Hi

Please help.

I was flying this same build-- ( apm 2.0 on a dji 330 frame motors and dji esc ) before and loved it.

It has sat for a few months,with better weather, I plugged it in and updated to the 3.1.3

No way will it arm the APM2.0

Originally, I was getting throttle failsafe error and HUD screen showing the error and double flashing red led, but turned off failsafes and error went away. ( just did that to get it arming OK first

Now It just won't arm, no lights, no errors, no esc It also fails to run the motors in the motor test on the CLI. 

.I have checked and rechecked many many times and no idea what to look for.

Twice I have hit the arm button and it has armed. arm unarm, arm unarm, tried on off, on off seem to  be fixed, although I dont think I did anything. turned it off and went to bed.

Next morning , wont arm.

Screwed around for another 4 or 5 hours redoing the same processes over and over again and suddenly, it armed. This time, I went in to some basic settings to set back to make it flyable, and guess what, I wont arm. I am probably 10 hrs in just sitting here trying to arm this thing.

There are no messages on the HUD

The LED does not double blink like it does on a pre test.- just the notmal singe blink and it does not change

Pre-check has been disabled to ensure that was not my issue.

I do not get any reaction form the motors when in CLI motor test, they do nothing.

It has armed a couple times throughout the process, but by the time I got the props on it again, it would not arm.

It looks like I am not the only one that has had this issue.

My wife is kicking my *ss for sitting here for hours on end, any help would be appreciate.

BTW it also seems that the " load previous firmware" that was in previous versions is gone? can not even revert to an older version ( or at least I dont know how)

Any help is appreciated.
