Is your firmware for the X1 only for 4.22 and up?
It is for any. The loading process is by sd.
That's too bad. Its hosted so I can't access it with an SD.
If you have signature checking disable on it then you can update thru the web gui and not the SD
How do I disable that?
I will look at the files again today to see if there is a way to disable it on the x3. If you have ssh enabled it can be done using ssh
Is there a special way to enable SSH?
Usually it is done using a sd image. If you can access the miner with putty then you have ssh. Otherwise again I would have to look at the image file again to see if there is a whole that can be used to do it from the web gui.
