I've updated the TFT firmware to BIGTREE_TFT35_V3.0.26.1
It seemed to go fine but towards the end of updating the icons, it couldn't find various icons to update. I presumed it meant it couldn't find them on the current system hence couldn't update them, but read on.
I chose the first Copy to SD card.... NOT the Unified Menu Material Theme?
Once the update had finished, it came up with

There is now no icon for level, but when I touch it, it now shows normal bed levelling, not the BLTouch

If I select to print the test Gcode that came with the SKR/TFT package, if I put the microSD card into the USB adaptor and plug it into the side of the TFT and select to print from it, it see's the microSD fine. If I put the microSD into the main slot (tried powering off), as soon as I select to print from main slot, it comes up with the following and hangs.

It worked fine before I did the update. However the microSD card that came with the printer works totally fine both ways.
So I've put the test code in the USB adaptor and selected to print it, it comes up with

Which seems to be saying there's nothing in that code to heat up the bed/nozzle, not a clue what this test is meant to do, so not that bothered.
and the screen behind that message looks like

I haven't tried updating the firmware on the main board yet, maybe that would help.
I've just retried printing the bed levelling test from the touch screen and it's come out fine (OK haven't sorted out extrusion yet and it's starting each square with a little splodge), so things seem to be improving. Icons on screen still same as previous pic
