I understand that point; just like normal updating process or suddenly lose power of Wii U in game (memory corrupted I just read last night); bad memory card when backing NAND... all poses some kind of bricking risk.
So let me just ask this straight away. With the updated sysupdater, it is as safe as KTM can get in case I get the correct firmware package for the 3DS (model, region), right? So no point to wait for KTM? I thought of KTM as some kind of stable sysupdater (downgrader), but new info seems to dimiss this notion.
