Still trying to fathom why this device can be a pain to boot....

Still working out why this device can be an absolute pig to boot from cold or reboot especially after an update.

This is my observation.

I have mopped up a few of these tablets that are broken with various issues and have got them running again.

So experimenting, I have some devices that reboot and cold boot into UT with no issues whatsoever.
I have some devices that are terrible to get UT running, but get there.

So I have found, if the device fails to boot switch it off and leave it for half an hour.
Then power on holding the volume up button. Release the power button when the Lenovo splash screen appears, then count to ten and release the volume up button and most of the time, the device will boot into UT.

The hardware experiment continues.
