No, that's not what I meant. Before you flash a fresh copy of stock rom, make sure to do a complete wipe. You cannot do that with the stock recovery mode and hence you install CWM. Just follow my instructions in the above post. Once you have wiped of all data, then flash the stock rom back. Always remember Root first then install CWM. If you do it the other way, you will end up getting status 7 error. Do post the result.
