You don't have to. I've probably flashed it about 10 times since i got it and haven't had to flash it after the first time. If you run into any problems then you can consider flashing it then.ficklecycler;30187 said:I hope this isnt a dumb question but do we have to format the card each time we want to flash? Im asking bc it takes sooo long to format my 16GB card.
