Any image hosted by a forum user, that is not in OMV's repository, is a BETA . This image transfer.sh/abKmQ/OMV_4_Raspberry_Pi_2_3_3Plus_4.img.xz is not in the OMV's repository at the time of this post. Further, OMV's SBC support is unofficial and for the current version of OMV only.
To say or suggest otherwise is misleading users.
