+Note, that RS0/RS1 for both SFP's have permanent pull-ups, but also have the pull-down option.
+Not connected/lost traces can still exist on an internal layer (Reset for example).

+While this switch has no USB ports, the USB pins appear to be on TP2 and TP3 on the bottom (to be confirmed)

The upside is, unless Zyxel recompiled their firmware (unnecessary work for them, but possible), using a smaller flash-chip would be less-likely.

 As an alternative, the XGS1210-12 U-Boot binary can be flashed, which turns the XGS1010-12 'more' into a XGS1210-12, [[https://gitlab.com/olliver/openwrt/realtek_sdk/-/blob/xgs1210/sdk/system/uboot/cmd/uboot_func.c#L62|which puts this self-check at the end of the flash]].
