No write access to internal sd (not ext. micro sd)

Hi all Im looking for some assistance with this issue please.

My problem...

no write access to int. sd when I had it prior to installing a modded obb file. (I think)
I can not move any file or folder with any file manager
camera will not store pics to int sd or display any pics in the gallery
No app with a obb file will install from the play store and gives error code (911)
Flashing a stock lollipop tar fails in odin.

What I have tried....

I have restored different 4 back ups. (stock rooted lp. sacs darklord and norma)
I tried to flash lollipop tar in odin and it failed.
I ran a command with a terminal emulator said to fix my situation.

I am currently back on sacs darklord rom via a back up and I can write to int. sd with my laptop.
