Surface 3 LTE is stuck installing the 2/4/2016 Firmware update while trying to get the latest Preview build - 383.
I had a similar problem with 379 but that update eventually finished.
This time, it got to 99% after a couple hours but then just sat there.
I restarted the machine and the Firmware update download restarted (at around 40% complete).
Now it's stuck at 59%.
Switched from Fast to Slow and restarted.
Firmware update still stuck.
Removed the SD card and restarted.
Still stuck.
Latest 'stuck' means that it's been at the same % for around 10 hours.
I'm going to let it continue the update for a while and hope it makes some progress and eventually finishes.
