Do not use this file for any reason as it has major bugs and can brick your phone.

If you dont know what this is check xda forums.

If like me you have used it then we are the lucky ones.

dude. you need to get your facts right.

1: its not a CWM error.
2: the bug is in the ICS Kernel released by Samsung themselves. It has an incorrectly written eMMC wipe procedure that causes the handset to hardbrick IF and ONLY if you perform a datawipe.
3: Enthropy512 is working with Samsung to fix this issue.
4: not all kernels are bugged. Chainfire from XDA has a VERY simple app to check if your chipset contains the bug or not. Google for it. its called.....surprise surprise "GotBrickBug.apk".

Do a lil more reading before hittin the panic button and tryin to scare the crap out of everyone here. Seriously.
