Rollback Firmware

Taz

I have 4 of the Reolink E1 Zoom camera's.
I have them added to the app on my phone and that works great.
I also had them added to my Synology so I could record the video to my NAS and that worked great.
I have been using them for some time now and recording to my NAS for some time.

I noticed a new firmware was out, so I installed it on one camera. Opened the app and it was still working and functioning so assumed I was good to go.
So I did 2 more, but then I stopped and I noticed that they stopped being recognized by my Synology.
The one I did not upgrade the firmware for still works great. The three I did stopped.
I removed all three from my NAS and started from scratch and they still do not work.
I removed the one that works and re-did it from scratch, and once again it still works. The firmware is the issue.

I am looking for previous versions of the firmware so I can roll it back on the other three, and I can not find it.
I am specifically looking for v3.0.0.65_20071008 as that is working on one.
I went to the download center and it only shows the current firmware.
There are no previous versions and no link to find previous versions.
I tried to use search and that did not come up with it either.

Please help.
