I have not been doing any kind of research about bridging those pins because I just read about it first time, but my experience about charging problems are very similar to yours. My TyTN won't charge normally via USB-hub or car-adaptor, and after failing the charging process, it won't start charging again. Resetting helps after this, but I think that also waiting resets the situation. But that I'm not so sure about.
When I connect it directly to PC, it works just fine.
If bridging those pins helps, my car charging problems are wiped out
