Have you ever upgraded your firmware on your Synology NAS server (maybe to a BETA version) and regretted it badly ever since? Do you lie restless at night knowing that Synology firmware is not down-gradable? Fear not... Here's (a) the solution.
This article describes how to downgrade your firmware on a Synology NAS server. This method should work with any version/model.
Please note that I cannot be held responsible if anything goes wrong - nor am I able to help you with your problems whatever they might be afterwards. Continue on your own risk!
1) Extract the VERSION file: First - I extracted the VERSION file from the synology_ixp420_junior_0368.pat file. I am planning to use the synology_ixp420_junior_0385.pat for the actual downgrade, so I use a firmware file which is older than 385 - in this place it is the 368 file. I used WinRAR (ver 3.51) to open the pat-file, which in fact is a TAR copressed archive file. The VERSION file is placed in the root of the TAR archive. I extracted the file to the public share on the synology 101j
2) Enable telnet or ssh. Use you webinterface on the DSM to do this.
3) Finding files: DiskStation> cd / DiskStation> find / -name VERSION ./etc/VERSION ./etc.defaults/VERSION ./volume1/public/VERSION
4) Verify content of file: DiskStation> more ./etc.defaults/VERSION majorversion="2" minorversion="0" buildphase="3" buildnumber="0426" builddate="2006/12/26"
5) Replacing VERSION file: DiskStation> cp /volume1/public/VERSION /etc.defaults/VERSION
6) Verify content of file after replace: DiskStation> more ./etc.defaults/VERSION majorversion="2" minorversion="0" buildphase="3" buildnumber="0368" builddate="2006/06/29" unique="synology_ixp420_junior"
7) Downgrade firmware using the web-admin-tool: - Logon via web-browser as user "admin" - Go to "firmware upgrade"
The folowing information is now showing: Model Name: DS-101j Current Firmware Version: 2.0.3 - 0368 Firmware Date: 2006/06/29
- Browse for the old firmware pat-file (synology_ixp420_junior_0385.pat) and click OK
- End -
