A few months ago I attempted to update my Nokia 3 TA1020 to Android Oreo, as I was impatient, but I've managed to render the device unusable.
I've tried several steps I've found online but it's stuck on the Android Recovery screen. I've tried applying an update from an SD card and plugging my phone into my computer, via USB, also doesn't work-Windows 10 attempts to recognise the device, then it fails.
I suspect I may be able to get it up and running again but it's how I go about it.
Many thanks for any hints and tips.
