I'm trying to get all of our SG200-26 Port switches to the latest firmware.
I know that there needs to be an intermediate step to version 1.3.5 where the boot code also needs to be updated.
It worked on all switches except for two, which are running the oldest firmwares in our company.
Both of them are running on Boot Code 1.0.0.6 and FW 1.1.3.1.
The problem is that it is not possible to update those two to any newer versions.
Trying to update the FW results in an error message saying that it has an illegal format.
Updating the Boot Code is not possible at all. When selecting TFTP there should be an option to select Boot Code like on the other switches I updated, but on those two there are only options for Firmware Image and Language File Updates, no matter if TFTP or HTTP are selected.
Does anyone know why there is no option to update the Boot Code on these and why it is not possible to update to any newer firmware (even below 1.3.5)?
I even tried factory reset on both, which did not change the behavior.
There must be some way people could update from these versions, but I can't find it anywhere.
