If I am not mistaken (have in mind that I have just returned from the bar

)...
Things to have in mind: shutdown the phone, take out the battery, wait, put the batteries again and start the phone.
Then if I dont remeber wrong, I think I RSD 3.3 with the "For_25P_yan0.sbf" image, then I waited some time to let it finish, then I restart the phone and lastly I installed MPKG yan0 directories to my SD memory (I mean .system and the inside stuff over my SD memory .system directories (remember that you will have to reinstall the softwares you already installed, to see it again in your programs list!)
Then I restart again, and the MPKG and the "two swords icon" showed up in the programs list.
Hope this helps!
