Surface 3 4G LTE: "critical" events logged for IA7260 Firmware Update

If you are doing all of this as part of the other thread http://answers.microsoft.com/en-us/surface/forum/surf3-surfmobile/surface-3-4g-lte-critical-events-logged-for-ia7260/cb5150f1-1928-4a50-85e5-4195a1f98394 - and this is a continuation of that thread, it would seem you have had issues since you purchased the device, but these issues disappear when you remove the SIM.

I would have thought you would have exchanged your device long before now..?

I'm going to merge this thread back into the original thread you started. I think that if replacing the SIM was not a fix, then exchanging your Surface 3 under warranty is the next step. See if the retailer where you purchased it will do this for you (preferable over exchanging via Microsoft).

Thanks Barb - It certainly seems that way, but its odd that the procedure appears on a few MS support articles stated to apply to Surface 3 (e.g. "What to do if a Surface is running slower", "Surface touchscreen: Problems with touch"). From out of the box, my Surface 3 has suffered from quite a few problems to which I thought this might be relevant, including  numerous user-mode driver crashes of the IA7260 Firmware Update "device" associated with the mobile modem (I have the LTE version) and severe problems with phantom touch (though this has now apparently been fixed by the N-Trig calibration tool, despite it being no longer supported by MS). Most recently, however, the Broadcom GNSS 47531 location sensor has also been showing prolific user-mode driver crashes of BcmGnss.dll, so the sensor is now permanently offline (I can disable/re-enable it to get it going, but it soon crashes again). I have re-installed the driver with no improvement, so wondered if a "battery out" shutdown might reset the hardware - before embarking on a third reinstallation of the OS (so far, one from the original recovery partition, one from a BMR download - with little effect on any of the issues). On top of this there are a few miscellaneous BSODs and the Reliability Monitor is sitting around rock bottom. So it's a mess... I've run the Microsoft Memory Diagnostic, showing no errors, the file system check shows no errors, sfc /scannow shows no problems - not quite sure what else I can try. Was thinking of trying to reinstall from a standard windows.iso image rather than the customised BMR image but can't really see why that should be any better.

Yeah, the 2 button restart does not apply to the Surface 3. What problem is causing you to want to do this?

Hello - I have been trying to apply a two-button shutdown to a Surface 3, using the standard procedure (1 - normal shutdown; 2 - press and hold power and volume-up buttons for at least 15 seconds; 3 - release buttons and wait 10 seconds; 4 - press and release power button to turn on again). However, I am finding this does not lead to shutdown: instead, it opens the UEFI/BIOS screen (AMI version 2.17.1246). I am not releasing the power or volume-up button early, as in the standard procedure to access the UEFI/BIOS. Can anyone suggest what might be going wrong here, or suggest any other way of performing a hard "battery out" reset? Thanks!

Mike_P_416 - Yes, I just removed it completely, so there's an empty SIM slot. (Initially done as part of preparations to return the device for repair/exchange - but I'm still fiddling with it, still faintly hoping for software/firmware remedy from MS. Have also disabled touchscreen to work round "phantom touches": so, with no touchscreen and no SIM, my Surface LTE is just fine. Sort of.)
