So, I have sucessfully updated quite a few SCDSTWO cards for 1.4.1 in my time, and I just got one that will not update. I have tried updating it on a DSL, DSi 1.4 and a DSi 1.4.1... (all Japanese versions) The odd thing is, the card will not boot up on DSi 1.4 or DSi 1.4.1, but will boot up on my DSL. So, it can't be completely broken... and I don't know why it won't run on DSi 1.4 ??? Does anyone have any tips...? I tried re-downloading the 1.4.1 update file, and it still won't update.
