so i have a 3ds with b9s and luma 8.0.2. I wanted to update my 3ds to the latest firmware but from what i read it seems you need to have the latest version of luma to safely update your 3ds. But when i try to go to luma updater and update i get an error that says "update failed" and "could not get A9LH payload" so i was just wondering how would i go about this thank you.
