Well you can take a look at the picture, maybe i am missing something but i dont see bootstrap or charge pump anywhere... They all are n channel mosfets... I removed them for testing, but they are ok... I tested almoust everything on the board, nothing is faulty but it doesnt work. Maybe mc died, but i cant see a reason... I understand how h bridge works, but i cant see how this speciffic one works, to be more accurate how upper mosfets connects 12V from drain to source ... If you want i can take more photos
