Hi,

Is there a way to obtain and safely downgrade to the older firmware (v 1.0.4) of the T3700G-28TQ switch that was installed by default?

Ever since I updated to 1.0.5 I cannot establish certain sfp links that worked perfectly before despite using genuine tp-link optics.

I get confirmation in the logs that ports have had the optics inserted correctly, but the ports never become active.

The same links with these optics worked correctly in 1.0.4, after an upgrade to 1.0.5 they are dead. Surprisingly other switches that I tested like tplink SG3424 work OK with the same links and optics, so it must be 1.0.5's fault.

The T3700G-28TQ switch has one primary (image1.bin) and one backup image (image2.bin). Does the backup image contain the previous firmware (1.0.4) and I could boot with it if I select it?

Thanks.
