There is a hall and phase wire combination that will make any brushless motor run forwards and backwards. You need to mix and match the wire combinations to figure out which combination works in the forward direction. The annoying part is that there are some combinations that will seem like they are working but will draw way too much current and damage your motor. I would suggest you monitor the current draw and look for the combo that yields the lowest current draw in the direction you want.
I have always heard that once you find the proper combo for one direction then you only need to swap any two halls and any 2 phases to reverse the direction. In my experience THIS IS NEVER THE CASE. I don't really understand it.
There are lots of threads around here with flow charts and strategies for searching for the right combination. I usually make a chart and systematically try every combo.
Be very careful increasing the current past the manufacturer recommended amount without a temp sensor in your motor. Its super easy to kill them. Cheap speed based ebike controllers ramp the current up super fast.
