Hi, I was looking to download SwOS v2.7p for CRS328-24P-4S+ to downgrade from v2.9 dew to fan issues (works in v2.7p). Looks like its no longer available at
https://mikrotik.com/download/archive. Does anyone have the firmware?
Thank you

Isn't 2.7p factory version? You should be able to run it by following reinstall/reset configuration manual (
viewtopic.php?t=137254#p679168). Since 2.7p would be > 2.7, the lowest available SwOS you can downgrade to would be 2.8 -

@Eider, thank you for trying to help, yes 2.7p is factory. I should have mention that the CRS328 that I am trying to downgrade to 2.7 it is at a customer remote site.

Your best bet is to open support ticket with MikroTik and ask for firmware file. There is no other way to remotely go back to 2.7p.
