Someone has already answered you in the tutorial thread. It is still possible, but you will need to buy a DS flashcard. Also, do not update your 3DS anymore or it will be more complicated to set up.
thanks but i have a question, your only chance to get CFW is to find someone that can setup Ninjhax for you. Ask in this thread or the official thread for more info. i have to get ninjhax first or do the mdset first?
