I have made a unofficial CM for you.
#include /* * Your warranty is now void. * * I am not responsible for bricked devices, dead SD cards, * thermonuclear war, or you getting fired because the alarm app failed. Please * do some research if you have any concerns about features included in this ROM * before flashing it! YOU are choosing to make these modifications, and if * you point the finger at me for messing up your device, I will laugh at you. */
You can go back to stock with Odin
Do a full wipe
Flash via CWM & report back!
I think USB doesn't work! Use Odin for flashing back
