so I am at line 68 - sh-3.2# ### Wipe - Format Data

the top blue area of the screen says Data Format Complete.. next line says successful

but the main window says...

failed to mount '/data' (Invalid argument)

Unable to recreate /data/media folder.

failed to mount '/cache' (Invalid argument)

Updating partition details...

failed to mount '/data' (Invalid argument)

...done

You may need to reboot recovery to be able to use /data again.

Updating partition details...

Failed to mount '/cache' (Invalid argument)

...done

do I have a permissions problem?

here is an ls -la at this point. I am going to continue just in case this is somehow normal... although I don't think it is, but now I know I should be able to start again....
