Your M8T must be newer product (seems to be spring/summer 2016 onward)
to have shipped from the factory with 3.01 TIM firmware that supports
Galileo, seemingly to the same configuration table provided with the SPG
3.01 release notes.
Although purchased in early December, my M8T has the older 2.3 TIM firmware.
The 2.30 TIM firmware will not support Galileo. It is not recommended to
use the SPG (Standard Product) 3.01 firmware to the NEO/LEA-M8T as you'd
lose timing functionality, and have no route back.
... historically u-Blox has not release firmware updates for timing
products publically, only in parts direct from the factory.
... it is probably a factory-only option, which would align with
previous policies not to release Timing firmwares publically.
In discussion: that after the Galileo constellation has completed its
validation phase, the 3.01 TIM firmware that is already shipping with
newer product may come available.
There is some hope. Various comments in the forum imply the 3.01 TIM
firmware is available, at least to valued commercial clients, via
official support channels.
