OK thanks for info.
Next problem of mine… when I flash to a USB drive, all is well, Windows shows the drive as the two partitions and the COREELEC partition can be browsed as expected. However, when I flash to a microSD card (I’ve tried 2 different ones), the card becomes unreadable in a PC, and despite Rufus saying the flash went fine, in my N2 only the red light comes on, no blue light, nothing on screen. This is an extra microSD card I am trying to set up to test nightlies, I already have a working microSD card that came with the N2 for my daily usage. The cards I’m trying are 32GB class 4 microSDHC cards. Card really needs to be class 10 as per instructions? Maybe the cards are damaged, I’ll buy a new one. They seem to behave OK when formatted for use on the PC.
