'No pen or touch input is available for this display' after reinstall
'No pen or touch input is available for this display' after Win10Home reinstall
After five solid days of bashing my head against a wall* trying to get Win1709 to update to 1803 on my Tesco Connect Win 10 Home tablet, I finally resorted to doing a reinstall from an ISO/usb from Media Creator. (The old version of Win 10 worked fine, but new security updates were backed-up behind a repeated failing/redownloading 1803 update and never installed).
.
The fresh installation won't respond to any touchscreen access (also is stuck in portrait mode), which is pretty useless for a small tablet with no external mouse or keyboard.
Hardware is Tesco Connect 8, manufactured by Viglen (both reasonably big-name companies here in the UK), otherwise I don't have much info on the hardware.
Atom processor; 1GB RAM, 32bit Win 10 Home, 32GB SSD, with a slot for a 32GB microUSB card
.
I found these drivers, but they don't help.
download.viglen.co.uk - /files/Tablet_PC/Connect 8/
.
I have looked for other drivers via a Windows "Check for updates". Windows found a few minor ("Defender", MST etc) updates and a couple of intel drivers, which didn't help.
Windows>System>About shows:
Device Specifications: Pen and Touch: No pen or touch input is available for this display
(the older (1709) version said "Limited Touch Support with 10 Touch points")
.
The machine is stuck in portrait mode (it used to rotate to landscape with the machine was rotated). The Action centre has no button for "Rotation Lock" and Windows> settings doesn't have an option to add it to the Action Centre. I can toggle 'tablet mode' on and off, but still no touch-screen.
.
I have rigged-up an external mouse via the microUSB/charger port (that is the only port, plus the uSD slot); The Accessibility on-screen keyboard works, so I can limp around to do some basic diagnostics, but can't (for example) do anything in Bios except look at the first page, as it needs an external keyboard, which I don't have.
.
I do have a Macrium image of the old, "won't do updates" 1709 version of Win10, so I could roll back to that if really necessary, but is there anything I can do to make the touchscreen on this new 1803 install work?
TIA

* don't ask! - Stuff I tried to get the old version to update before giving up on it (probably redundant here, but included just-in-case):
regular positive path update gives 0x800706ba
Updates Troubleshooter gives 'Potential Windows UPdate Database error detected', not repaired.
Standalone troubleshooter (file: (20170905.cab) gives "Ununexpected error has occurred. The toubleshooting wizard can't continue".

0x800706BA - 0x20003 The installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation
new w10 install tool (Windows10Upgrade9252.exe) run from C: gives "Something went wrong, 0xc190020e"
