cmon guys, some of you people at least read the topic before you post...
First of all, update at your own risk.
ok, then.
1) You NEED a DSi, DSXXL, DS lite or Original DS to update your flashcard. NO, I repeat, NO updating possible with a 3DS. So if you have none of the old DS's anymore, don't bother posting
2) If your Hardware ID is 81, you can update it normally.
If your hardware ID is 44, YOU CANNOT UPDATE. Don't bother posting or asking, it won't work. Wait for an official update.
3) No matter what you do, YOU CANNOT BRICK YOUR 3DS with this.
How to find out your Hardware ID?
Touch the start button/word in the lower right corner of your bottom screen. Tap more, tap help. That should give a pop-up window. Your HW ID will be written next to the Akaio version on the bottom of the window.
So, you have a DSi, DSXXL, DS lite or Original DS and a HWID:81 card? Great. Follow these retard proof steps:
1) Put the update file on your MicroSD card. (get the correct file for the correct console, so DSi version for your DSi, DSXXL for the DSXXL etc...)
2) Run the file on your DSi, DSXXL, DS lite or Original DS.
3) Press start. Don't touch your DS until the process is finished
4.1) Follow any instructions the application tells you to do (i.e. Read English!)
4.2) Reboot your DS when the app tells you to, not before.
5) Try running it, if it works, congratulations, you now have an updated AceKard 2i
6)If it doesn't work, remove all the Akaio data from your card (_aio folder and akmenu4.nds) and recopy the latest version on your card.
7) Enjoy
