Spondoolies SP30 - firmware update

[rogales141]

Hi All

I'm heaving some issues with software on my SP30, currently running on the SD card. I really think the update will be a solution, plus it gives lots of options compare to my current: 2.3.27.

Have the image of 2.7.1 but in my current webUi doesn't have an option to upgrade from file, and automated option doesn't exist since Spondoolies servers don't exist. Have you got any suggestions how to upgrade it?

Is it possible by SSH? How?

Thanks in advance!
