I have mislead you about NEO-M8T-0-10 TP 2 capabilities, sorry.
https://www.u-blox.com/sites/default/files/products/documents/NEO-LEA-M8T_ProductSummary_%28UBX-16000801%29.pdf does not differentiate between two outputs and lists range as 0.25Hz-10MHz.

Regarding flash/no-flash bootleg versions - mask ROM firmware residing on the die does not support FTS functions (there is not enough space for extra features and increasing the die size would increase base product cost) so if you have FTS product then it must have flash inside to run the code from. Whether this flash IC is of adequate size to accept future updates or whether its erasing and writing is supported by the main firmware in ROM is a separate question. It is technically possible to create operational but non-upgradeable FTS product .

Hello Time Nuts!

Sunday, January 20, 2019
Thanks for all the replies, I am now in e-mail contact with Alexander
at the sellers place. He asked last night if there's a jumper on the
underside of the GPS board. At first I thought there was a tiny SMC
resistor or capacitor. It was in an area where flux residue existed,
so looked like a post manufacture addition. Upon cleaning off the
residue I now think there IS a solder jumper fro pin 1 of the Ublox
to somewhere else, maybe to the power supply area. I wonder if pin 1
is being held high or low? I am impatiently waiting for Alexander to
see the photo and advise, what do you guys think? The photo is at
http://www.chriswilson.tv/gps.jpg Up to now all attempts to get any
output from pin 1 have failed. Thanks for all the replies again!

Best regards,
Chris mailto:chris@chriswilson.tv

Hello Time Nuts,

Tuesday, January 22, 2019

The Ublox M8T is now fixed! For future reference this is what was
wrong. CSG Shop ship various versions of this GPS module on a generic
board, as far as I can tell, and reading between the lines. Some
versions need this jumper across two of the three normally bare
solder pads. Mine seems to have "escaped" with a Neo_M8T but the
jumper soldered in place needed for NEO_M8L and NEO-M8U modules. Upon
removing it the device now outputs under control of the current
release of U-Centre software on TP0 and TP2. On another list I have
been warned to only capacitively couple TP2 to "whatever" in case
"whatever" pulls TP2 to low, which would put it in Safe Mode. If
anyone wants a photo of how the pads should be for the M8T I can take
one and link here. But basically the M8T module should have NO
jumpers across the three pads on the reverse side of the board...A
learning experience I could have done without, but at least I have
learnt something and it can now be cased up :) Thanks to all for help
here and by direct e-mail.

Best regards,
Chris mailto:chris@chriswilson.tv
