Firmware update fails

[fxwalsh]

Hi
I'm using SiPy board with Expansion Board 2.
Details as follows:
(sysname='SiPy', nodename='SiPy', release='1.6.3.b2', version='v1.8.6-470-gf41d0f27 on 2017-02-22', machine='SiPy with ESP32', sigfox='1.0.1')
I followed the instruction for updating the firmware.
All progressed as expected (selected siPy board and Europe region) until the downloading part where it just stalls.

The next button is available but if I click it just says Result.
I would expect to get the ID and PAC.
I'm using Firmware Upgrade tool on Windows10 (v1.1.2.b1)
I have managed to connect and run code on the board using Atom and relevant plugin - ID and PAC are all 'fffff's.

Any help would be greatly appreciated. Is there a way to manually flash the board?
Thank you!
