I have it working on SD but haven't tried with new device tree for the fix for wifi. I also have a MAC. What's the worse that can happen if I mess it up because that sounds very confusing I've never ssh before.....
What is that s805 at the bottom of your post ?
Make sure you are using correct chip.
Exactly what box are you using ?
If you are on a Mac it is the easiest.
It is not confusing. You Must have a working SD Card LE Install. No If's or Maybe's. It has to be working including WIFI.
If your Mac and Box are on the SAME HOME NETWORK using terminal application to issue commands to your box is easy.
You are basically issuing commands to access the box first then you are issuing commands to write the LE version from your SD Card to Internal memory. That is all you are doing.
Working SD Card version first please.
Let me know if you need more help.
