Hello :)

Here is Intel TXE FW 1.2.1.1153 (1.375MB) Date 20.08.2015

Intel TXE 1.2 1.375MB Firmware v1.2.1.1153 BYT-T

The latest driver (1.1.0.1064) can be found at the first post, section A1.

No, v1 drivers are for all BayTrail systems whereas v2 drivers are for all Braswell/CherryTrail systems.

There have only been 3 TXE 1.x driver releases since 2013:

1.0.0.1050, 1.0.0.1054 & 1.1.0.1064

At Device Manager > System Devices > Intel Trusted Execution Engine you should see the driver version of 1.1.0.1064. That's the latest, generally TXE very rarely has driver updates.

Any TXE 1.x system can be upgraded to latter minor releases so 1.0 --> 1.1 --> 1.2. However, the minor version upgrade requires an unlocked flash descriptor and then custom work with Flash Image Tool and Flash Programming Tool flashing. To detect is the flash descriptor is unlocked (almost never is on tablets) you can run fptw -d spi.bin command via Flash Programming Tool. If you get Error 26 then you have a locked flash descriptor and nothing more can be done via software solutions.

@ Arise:

Use v1.1 System Tools, they are newer and compatible.

* I made some major changes to how TXE 1.x is detected and categorized based on some recent findings. Some firmware remained the same with a slight name change when others were wrong and got replaced completely. In detail:

1.375MB v1.2.0.1149 BYT-M/D --> 1.375MB v1.2.1.1153 BYT-M/D
1.375MB v1.2.1.1153 BYT-T --> None

3MB v1.0.7.1133 BYT-T --> 3MB v1.0.2.1160 BYT-IT

Note: The above firmware changes will be visible with MEA 1.4.x or later. It will be released in the near future. The current version does not detect properly the M/D or I/T platform.

Intel TXE 2.0 1.375MB Firmware v2.0.1.2091

@clio

Honestly, the difference between M/D and I/T same-version firmware is non-existent content-wise but not check-wise. I have seen many people manually (programmer) flash M/D firmware on I/T platforms or vice versa and it was working just fine. In general, TXE 1.x is such a big mess. Nothing like ME on that regard.

Anyway, you need to update to the same firmware that your SPI/BIOS has, even if it's "wrong" in theory. If that's what the OEM has flashed then that's what you can update to. In your case:



So, from the first post you need Intel TXE 1.1 1.375MB Firmware v1.1.4.1145 BYT-M/D.
