@JonEnErgYv2 To test if your Pro is compatable with linux try the 'NO-USB-Linux-Loader.bin' below.
You will need to use my exploit menu because it has a modified version of BinLoader to load large bin files.
(In the menu go to 'Tools 1' > 'BinLoader Extended')
Because the 'NO-USB-Linux-Loader.bin' is 10MB it will not work with the regular versions of BinLoader.
Just extract the zip and load the NO-USB-Linux-Loader.bin with 'BinLoader Extended' in the usual way woud load any .bin files on your PS4.(Do not plug in your USB drive)
If it works and it loads the Linux rescueshell screen it means that your Pro IS compatable with Linux and it was your USB drive that is causing you the problems.
If it doesn't load the Linux rescueshell it means your PS4 is not compatable with Linux.
