Updating XG310 running 17.5 MR15

Hello RJN,

Thank you for reaching out to the community, for the mentioned Bug: NC-61506 the Affected version was SF 17.5 MR12 (17.5.12.664) [Components Firmware Management] and similar Bug: NC-70753 the Affected version was SF 17.5 MR15 (17.5.15.746) [Bali] -  [Components Hardware].

You can download previous SFOS Installers [ISO] from here: https://download.sophos.com/network/SophosFirewall/installers/index.html

And if you want to just download the previous firmware then that can be downloaded from here: https://download.sophos.com/firmware/HW/index.html

Thank you for the firmware links. I see that there are both "HW-17.5.17_MR-17.SF300-837.gpg" and "HW-17.5.16_MR-16.SF300-830.gpg" that would appear to be compatible with my XG310. However, this KB seems to indicate that 17.5 MR17 was only for XG85 and 105: https://community.sophos.com/sophos-xg-firewall/b/blog/posts/xg-firewall-v17-5-mr17-released 

Is there any more information about NC-70753? Is it a hardware fault since it is listed as "Components Hardware"? This XG310 is a rev 1 and I have a newer XG210 rev 3 that it could be replaced with if necessary.

In the scenario NC-70753, hardware was processed for RMA !!
