Firmware Upgrade - New Firmware could not be uploaded

This is a known issue. The following usually helps:

1. Please use Chrome to upload (If this doesn't help, try firefox instead)

2. Please make sure, you do upload Firmware via a fast LAN Connection (Not via a slow Internet Connection, this probably makes the Upload fail)

I've tried using FF, Chrome and IE, but I get the same issue. I'm performing the upload from a fast LAN connection.

Then the following steps are next:

• Proof, you really try to upload the correct Firmware (Version).
• Reboot Firewall, Try again.

If that still doesn't help you should consider Sophos Support... It's maybe related to your Cyberoam Hardware which I do not know very well.

I'll open a support ticket and report back with whatever the solution is.

Update: The tech support guys suggested using CRLoader to upgrade the firmware, however, when I tried that, I get informed that this firmware can't be used with the current loader. This would explain why the firmware upload is failing in the web interface, just a pity I had to the take the firewall offline to discover that I need an updated loader.

UPDATE and RESOLUTION:

After a week with dealing with Sophos support, and several hours of remote support, it was finally discovered that I'd somehow managed to download the firmware for the virtual appliance, rather than for the dedicated firewall.  Oops!!

In my defence, both the filenames are very similar, and the Sophos support guys didn't even realise either, even though they had tried to upload it themselves.

Dedicated firewall firmware filename is: HW-SFOS_16.05.6_MR-6.SF210-266.gpg

Virtual firewall firmware filename is: SW-SFOS_16.05.6_MR-6.SFW-266.gpg

It's only now that the filenames are obviously different, but I was obviously paying too much attention to the versions numbers in the middle.

Thanks for your Update. That's why I suggested to proof, you really try to upload the correct Firmware (Version) :)

It's really a big painpoint of Sophos's Firewall that they are not able to give us a better feedback, if we try to upload a wrong File.

True. It would have saved a lot of time of the firewall had reported back with a helpful error, such as "Incorrect Firmware File" rather than just "Unable to upload firmware"

If device is Cyberoam , please upgrade the cyberoam  firmware with the latest version than you can migrate to SFOS.

Thanks

Just an FYI that may save someone some time.

We had a similar issue on an XG86 trying to upload v18.

We downloaded the firmware for a 125, then downloaded the 86 firmware. They were the same file, so windows created the file name with a (1) in the name.

The XG rejected it due to the filename being different. Renamed the file to the original filename and it uploaded perfectly.
