Hi,

I don't know if this can be linked to your pb but I notice you mention :

Listing directory: /config
|__ FILE: config.json (0 bytes)

And I have lot of problem when my config.json file is corrupted to 0 byte.
In my case the config.json file is corrupted quite often when I flash my device... I don't know why...
(See my #41 issue)
