Default [PROBLEM] N7105 LTE Internal memory problem since 4.3 uodate.

I recently updated my Note2LTE to 4.3 via Odin, everything went fine as normal,
but after a while I opened Root Explorer to check my internal drive for my data and the update had wiped everything (exept a few folders, but theyre all empty!)

The problem is that my phone is stating I have 16bg (10gb before update) but only have 856mb left! Its like all my old data is still there but I cant see it anwhere. Has I corrupted during the update? I had a search online for this issue but cant see an exact match for this problem.

If anyone has experienced this can you please get back to me.

Thanks
