So flashed the boot.img using fastboot (not sure if that was correct) and..nothing, then factory reset and reboot and its on.. big thanks for both your help. does this mean i should never reset it?
p.s my fingers are killing me

@Luksus Thanks, how do i flash this manually with this image ?

@MrT10001 Thanks for all your help. I had tried most of that before asking on here and now im well past the vodka stage!! it going back into the cupboard

Been nearly a hour, try rebooting?

@MrT10001 Thanks, been about 10 mins on the boot logo on this attempt, keep leaving it like this and wait longer?

Hey..
So i got out my old Lenovo Tab M10 X605F today which had 16.04 stable on it and wanted to give 20.04 ago, so i re flashed it using the installer (app image) all went fine and installed successfully, asked me to remove usb.. then went on to installing updated for 5 mins and then rebooted and stuck on Lenovo logo.

Tried to reboot, factory reset (can get into recovery) nothing, tried to flash again.. still the same.
tried reinstalling 16.04 back on it and it doing the same, stuck on boot logo.

Any tips??
Thanks
