LoPy SN 1711004932

• The firmware version MicroPython v1.8.6-237-g9d21f17 on 2016-12-15; LoPy with ESP32

Yesterday I struggled to update pysense SN 1714001136.
No success but I was able to connect via Com11 to the LoPy via tera-term and get above info.
Finally today (20+attempts) it succeeded with response:
F:\Development\LoPy>dfu-util-static.exe -D pysense_0.0.8.dfu
dfu-util 0.8

state(2) = dfuIDLE, status(0) = No error condition is present
Done!

I then tried updating LoPy with pycom_firmware_update_1.1.6.b0.exe and it won't connect.
Tried tera-term and com11 no-longer available.
Neither FileZilla nor Atom will connect to ftp port
pysense is detected by Windows10 device manager as libusbK device USB\VID_04D8 & PID_F012
driver version 3.0.7.0

How do I correct situation to move forward?
