I read on comparisions between flashing the DS and simply using a passkey that you can brick your DS using either method. I understand that Flashme has a security feature that, once correctly in place, can allow you to re-flash your DS in case your firmware gets messed up. I can understand how you could brick your DS in the process of putting the Flashme firmware on the DS in the first place, so I can see why that is handy. But I also read that if you don't use Flashme and just use the passkey that you run the risk of permanently bricking your DS because you don't have that security feature that the Flashme provides. My question is this: what would you do that that would cause your firmware to get corrupted or overwritten if you never flashed the firmware to start with? Does the simple task of using a passkey device risk deleting your firmware? This rationale doesn't seem to make sense to me as a con of not flashing your DS. Can anyone clarify?
