Unhappy [Q] stuck by all means

Hi all,

I wanted to get back to Stock Firmware on my Tabblet 10.1 but something wend wrong.
When I now go into Recovery Mode normally you have 2 options:

1. The icon on the left, to go into the Recovery option (whipe data, etc.)
2. The incon the right, to go to ODIN2 Download Mode

Option 1 doesn't work, I can try click it, but doesn't go to a next screen, instead the icon disappears for 1 sec and comes back. I can only go into ODIN3 Download Mode.

So, now i tried to install a CMW package, got error that the ''Partition size is small!!''.
When i triy to install the Stock Firmware - Also got the error that the 'Partition size is small!!''.

I tried to load a .PIT file to set the partitions back - what seamed to work - but still the same error when I try to install anything.
My main problem is that I can't remove any data on the Tabblet and install the any Rom or Recovery Tool to solve the issue.

Do you have any idea how I can solve this paradox? I cant install a recovery tool or a Rom or anything due the Partitions error

Thanks for the Support!!!
