How is one supposed to upgrade an SG-300-52 from 1.3.0.62 to current?
The release notes for 1.4.7 say:
Upgrading from Versions Earlier than 1.3.5
When upgrading the device from version prior to 1.3.5:
• For Sx200/Sx300 models, first upgrade the device image to image version 1.3.5.x and upgrade the boot file to 1.3.5.06
Yet there is no available download for 1.3.5 and none of the 1.4 images will load.
