Surf Soho 8.3.0 firmware update fails validation

After downloading the latest Surf Soho 8.3.0. firmware and attempting to upgrade, I get the error message “Error: Invalid firmware image.” I have tried downloading the image twice, and I have upgraded twice with the same error, so I don’t think it is a downloading issue. (I am upgrading from 8.0.0.)

Hi…

You need to go 8.2.1 before 8.3.0.
Download it from here. Firmware & Documentation- Peplink

I tried 8.2.1, and got the same problem. I then tried 8.1.3 and got the same problem too.

Hi…

Please… share your status screen… not the serial number…

Model and Hardware revision are the information to be visible.

Turns out I have a Surf Soho Mk3. The MK3 is not specified anywhere on the acutal router, hence my mistake. I installed the latest MK3 8.3.0, and it worked. Thanks for all the help!
