Hi all,
Got this charger in "bricked" condition, it got a MA84G564AD4 inside, I have entered DFU using 47k resistor and a tweezers and flashed it with a firmware from Hobbyking (tried both patched and original).
On power-on charger is most likely doing a self-test, and I get EXT TEMP TOO HI message on the screen after few seconds all the time.
I have tried shortening out pins on the external sensor connector, I have checked all PCB for dead or damaged parts, but have found none. Tried to google that out, but there are no solutions in google.
I did read somewhere, that somehow I can disable external temperature check.
Could you please advise what should I do? I have literally run out of ideas.
