FYI it is assumed for Installation guides that users read/know basic OpenWrt (and Linux OS as a whole) before flashing, so they would typically know the default root/no-password login to any clean OpenWrt install. Nevertheless, it could be forgotten after using the Askey oem login, so I added a note to the doc for clarificaiton.
@Tobias I just plugged a 32GB drive (way beyond FAT capacity) into my Windows 11 PC, right clicked on it, clicked Format, selected FAT32 from the drop down, and it formatted in seconds. What am I missing here this is very easy in Windows.
