RaidSonic IB-NAS4220-B sysupgrade

Hello.

I landed here because I'm trying to update WRT on my RaidSonic IB-NAS4220-B, and this folder does not contain a raidsonic_ib-4220-...-sysupgrade.bin file, only ...-factory.bin. The Techdata page mentions those ...-factory.bin images as "Upgrade URLs" (and to add to confusion, for some reason it links to ext4 versions, even though by reading this forum I got the impression that a 16M ROM device should be definitely used with SquashFS).

Anyway, after a lot of fearmongering I took my chances and uploaded the ...-squashfs-factory.bin image via the WRT's LuCI interface, and it seems to have worked. So I'm leaving a post here just in case another uncertain noob like me ends up in this thread in similar situation.

while i appreciate your contribution, this is a dangerous recommendation.

for DLINK devices it will not brick your router, but certainly would require the use of recovery mode with the correct image.

as @hnyman alluded, there is a lot of variation between manufacturers.

suggests that a 'sysupgrade' image is available.

please do not make this recommendation to noobs since they may faint by mistakenly assuming their router is bricked after flashing the wrong image.

for DLINK devices it will not brick your router, but certainly would require the use of recovery mode with the correct image.

Yes, but (unlike NAS4220) there is a ...-sysupgrade.bin file for D-Link devices in the release folder, so there is no confusion to begin with.

Techdata suggests that a 'sysupgrade' image is available.

I guess I have eye problems because I fail to find any mention of it, barring the "Conventions for dataentry values" example at the bottom...

oic what you're saying.

yeah i saw "Firmware OpenWrt snapshot Upgrade URL" and assumed it would have a sysupgrade suffix, but i guess not.

nice eye, but i would still use that page as the ultimate guide. i guess you sort of lucked out by not reading the techdata page and still flashing the factory image without issues :>

@ScumCoder Yours is an edge case. When available one should always flash a sysupgrade image to upgrade from OpenWrt, when available.

The fact the factory image is linked for sysupgrade in that wiki page means it's meant to work. However, I think nowadays a sysupgrade image is what gets built by default if you don't tell the build system to provide a factory one - and I think kind of the opposite happened here.

Might be sysupgrade wasn't around or as widely supported when your device gained OpenWrt support.
