Default Cannot access my Internal Sd card anymore


I have a rooted device and have reflashed a new stock Rom.
To access again my Ext Sd card, I had to modify the file «Platform.xml». I have done it and have restarted my device. Since then, I don't have access anymore to my Internal Storage, External Storage and many programs don't work anymore . I have still access to the file Platform.xml but I can't modify it because my keyboard doesn't work.

I have reflashed it again but it still doesn't work.

Any help please.

Thank you,


Reflashed 3 times and factory reset and it works again
