Hi. I want to install OpenWRT on a Cudy M3000 router. It lists two different images - one for install and other for upgrade. From what I can gather, install is for installing OpenWRT from within existing OEM firmware, and sysupgrade is for upgrading from within OpenWRT. So I should pick the install option, right?
What confuses me a bit is in my other Cudy router (WR1300), both install and sysupgrade images are the same. So does that mean Cudy uses OpenWRT by default in WR1300 but with a different UI? And it uses some other custom firmware in M3000, so install and sysupgrade are different images?
Is the following a safe general assumption for all routers?
If install and upgrade images are different, then choose install for OEM firmware --> OpenWRT, and upgrade for OpenWRT --> OpenWRT. But if they are the same, then it doesn't matter.
I just want to double check because I read somewhere that choosing the wrong install image might brick the router. Thanks.
They are not the same in M3000. Kindly take a look here. One is openwrt-24.10.1-mediatek-filogic-cudy_m3000-v1-initramfs-kernel.bin and the other is openwrt-24.10.1-mediatek-filogic-cudy_m3000-v1-squashfs-sysupgrade.bin.
From what I understand, I should first install the official Cudy version of OpenWRT (intermediary), then install the latest OpenWRT sysupgrade from that. But why is there a different install bin file there?
I see. Thanks a lot. For future references (in case of other routers), can you verify if the assumption I made in the post is correct?
If install and upgrade images are different, then choose install for OEM firmware --> OpenWRT, and upgrade for OpenWRT --> OpenWRT. But if they are the same, then it doesn't matter.
