Flex 5 1470 BIOS Update 4QCN42WW

Has anyone successfully updated a FLEX 5 1470 to the new BIOS update? I can download it and start the utility, it goes thru the windows restard and then once it tries to install the BIOS (outside of windows environment with the BLACK screen with RED letters) it FAILS and then the next screen you press SPACE to restart the computer. Any ideas?

What's DOS?

Re: Flex 5 1470 BIOS Update 4QCN42WW43WW

I am also looking for ways to downgrade the most recent BIOS upgrade (i.e., 4QCN48WW(V2.12) of 13/DEC/2018) to factory settings (that is, version 1.0) for my Lenovo Flex 5-1470 (Type 80XA).


This is because, after the upgrade, my touch screen stopped working. I noticed that one of  the "I2C HID Driver" driver in the  "Device Manager >> Human Interface Device" application has not been "migrated". This was not happening before the upgrade.
