I have tried... and failed. The watch still works, but my efforts to send config bytes to the BMA421 have somehow put it the chip into an unreponsive state. I suspect I have overwritten its NVRAM somehow, as it won't even respond to a reset command.
Even powering down the watch doesn't seem to bring it back, and any reads from the BMA421 registers just return 0xFF.
Any ideas?
