post 1 YAY!
anyone else having issue with their internal (not sierra) GPS not working after latest windows/defender updates?
been bringing in our 31's to update and the GPS is going wonky. sees data, but never gets a location
tried "reflashing" with the ubx / DOS script, but it fails on step 1
almost like its being blocked

That had me thinking. Try swapping hard drives between working//non working units.

If bitlocker is disabled on both machines there should not be any problems with just swapping 2 working drives..
Get into bios and verify everything on the security page is disabled.
I do it all the time. Sometimes you end up having to reactivate windows, but that is simple.

well-- back to square one.... getting some more of these not working
tried the GPS viewer- It shows data coming in (lots of 99,99,99,99,99's mixed in there.)
it will pop up about 5-10 satellites on the screen for about 1 second, then disappear for about 5 seconds (repeat)--
never gets location, shows ZERO sats in use, and Status: Invalid
I have been sending these things in for "repair" and they put in new GPS modules...so far most have come back, I run the UBX thing on them to get NMEA, and they work.....buuuuuuuuuut, I got one back yesterday, and it was not cooperating.
the latest updates I have done: win updates, latest java, anyconnect 4.4, BIOS (intel security fix), and latest Mawarebytes.
Note that I have one in here now that has not had those updates yet--and its not working--even fully removed malwarebytes.
its almost like something is interfering with the GPS---maybe not all of ot, but some of the signal or connection to the device somehow.
I reaaaly need to find out what's going on.
