Es que éso es lo que no me cuadra. Luego a la tarde intentaré traducir con calma lo que dice porque no lo veo claro en relación a lo que se está comentando aquí:

Well okay according to this:

I am really sure what happend. While downgrading the bq really got a wrong firmware command and this caused a fail flash :
From the layout i saw in my Arc (i opened it and tried to track the lines) i don't see that SE has integrated the development board into the smartphone board.
I think the only chance to repair this little bastard is to desolder it, build the development board and use TI bqeasy software to reprogram it. BUT i'm not really sure if it is the real solution to this problem. From what i understood the BQ inside the smartphone is only connected via I2C bus, this bus is not repsonding at the moment. With a little luck we are able to reprogram the little bastard with the development board, but there is no gurantee for that.
I think that the best thing would be to resolder a new BQ chip and program the latest version via SE's modified I2C program tool. THIS MAY work.
