BQ78350-R1A: Can't write DF

Part Number: BQ78350-R1A
Other Parts Discussed in Thread: BQSTUDIO

Hello;

Out of the blue while updating the CC_Gain in the DF, the 78350 seems to have crashed, because now I cannot undo it. I cannot write the DF at all. I note that the OperationStatus reads 0x00002D0F, which would indicate that it has shutdown: SDV (Bit 10): Shutdown triggered via low pack voltage, despite there being 14V at cell 5.

Oddly, if I let it run anyway, it will run for a few seconds, reporting valid cell volts (but bad current readings)...but then stop replying to my host micro. 

Is there any means of correcting this via some command? I've sent the reset command but it does nothing. And unfortunately, the board is not designed to support bqStudio.

Thanks
