I just upgraded to 7.8 on one of my routers.

It appears the SFP ports don't work (Which is bad ).

My question is, per this link: https://help.mikrotik.com/docs/display/ ... g+RouterOS

It shows that I have to use the factory default version on the router, but I just want to go down to 7.7. What is the simplest path to this solution?

first -> drag and drop v.7.7
second -> /system package downgrade

@DaneelOlivaw200, I think you are misunderstanding what it says: (quoting it)
-------------
Yes, you can downgrade RouterOS, but only until the factory installed version, which you can check with this command:

/system/resource/print

uptime: 4w4d18h21m5s
version: 6.49.6 (stable)
build-time: Apr/07/2022 17:53:31
factory-software: 6.45.9
The factory-software is the oldest version supported by this device.
------------

The point it is making is that you can install any version from 6.45.9 or higher, but nothing lower than the factory-software, which is 6.45.9 in the example they gave.

So you can downgrade to the version you were previously using directly, no need to go all the way back to the lowest version your device supports, and then upgrade.

If you have not done so already, make a backup and save an export as well.

You may want to watch this youtube video. MikroTik Tutorial 101 - How to Downgrade your Firmware (but I don't understand the reason for downgrading the bootloader firmware (the routerboard firmware) "upgraded" in the last step of the video, I have never done that, I never use that step unless it is actually going to upgrade the firmware). The official docs don't instruct you to do that part when downgrading RouterOS)

You don't specify what device you have. If your device has enough flash storage, you can make a backup of your running partition to another, so it makes it possible to revert more easily. See Partitions

This worked. Thank you!

Yes, I think you're right. I may have misread it. The process was very easy to downgrade though, I must say!

Is the https://mikrotik.com/download page showing any ROS software for anyone?

Here is what I see:

You have to manually upload NPKs for all packages currently running (e.g. routeros and wireless) for the target version and correct architecture. then execute "downgrade" and reboot.

After router boots up, it should have something in /log/print explaining why upgrade or downgrade did not succeed.

Don't forget to upgrade the firmware the RouterBoot, if you have very old version.

Ah sorry there must have been some misunderstanding i have uploaded the npk file in mikrotik then downgraded but still didnt worked. Please have a look in the files of mikrotik i have provided above "0 routeros-7.13.5-mmips.npk package 9.0MiB 2024-04-03 14:54:15"

Did you check log after reboot (which was supposed to downgrade but failed to do so)?
