MSP430F5510: BSL Python Upgrade Tool with Info memory

I am trying to use the Python upgrade tool to flash the MCU using the BSL.  

I run into an issue if the hex file contains code to load into Info Memory.  hid_1.py will hang on line 66 with self.write_report(txdata).  It shortly times out and throws this error:

File "D:\Work\Active\Semler\BT Sensor\MSP430USBDevelopersPackage_5_20_06_02\Host_USB_Software\Python_Firmware_Upgrader\python-msp430-tools\msp430\bsl5\hid_1.py", line 137, in write_report
self.hid_device.send_output_report([ctypes.c_ubyte(x) for x in data])
File "C:\Python27amd64\lib\site-packages\pywinusb\hid\core.py", line 559, in send_output_report
raise HIDError("Write timed out")
HIDError: Write timed out

If I remove the Info Memory code from the hex file, programming completes normally.

I understand there is a lock for Info Memory A.  Is there something special I have to do to mass erase the MCU and update the code including INFOA?
