flyride Posted October 25, 2021 Share #2 Posted October 25, 2021 DSM is archived on Synology.com website. https://archive.synology.com/download/Os/DSM Maybe you know this already.

Nikalas Posted October 26, 2021 Author Share #3 Posted October 26, 2021 Hi @flyride The Version: 6.2.3-25423 is not available on the archive. The problem is that I have an installation that crashed and is requesting again the firmware that was installed previously (25423).

flyride Posted October 26, 2021 Share #4 Posted October 26, 2021 I'm aware 25423 is not on the archive, that is why I asked the question. Usually there is no problem installing a newer version (25426), only a prior version. If that doesn't work (you say it doesn't), I'd search for threads on reinstalling a backrev version (i.e. bricked because someone installed a new version they should not have). There should be instructions to modify the loader and complete the recovery install, which should allow you to use an earlier version (I suggest the latest version you can download prior to 25423).
