Hello all. I recently bought myself an 3DSXL as a graduation present and wanted an R4 card to go with it. I had a ds lite back in the day but gave it to my sister so want to revisit all those old games. Anyways I was aware of the cat and mouse game of releasing new cards with each fw update (thanks to lurking on this forum) and decided that investing in a DSTwo would be the best option. I bought it from 'TheGamerDepot' and it arrived about 7 days later. and once I followed the instructions I got the 'error please power off' message, so I tried to redo the installation process. I did the same thing and this time it worked and I got into the DStwo OS and even played a game. However the next time I got the error message so began to think I needed to update the firmware. I followed both methods on this site for updating my card's fw (leaving for 3 mins on error and trying to do the traditional method) but neither seem to work. When I get into the DStwo's Os I do not get any message prompting me to update. TheGamerDepot say they ship each card with the latest fw so I suspect it's already updated and this is the reason I cannot update. However I'm still left with a card that I cannot play. I have played it a few times and it seems to work when I put my microSD into my computer, eject then power on my XL. But returning to the home menu and trying to load the OS back up again I get the error message. This is very frustrating and I'm at a loss of how to fix my card. It works 100% of the time in my sister's DSlite but about 5% of the time in my XL. I have also tried to update the fw on the dslite but cannot get the update to prompt when it's loaded on there. Does this suggest it's already on 1.19? I've sent an email to the site I bought it off and two days later I got an 'out of office' response. Sorry for the long post, but looking for some help and advice Also forgot to say my 3DS is on the latest firmware. Cheers.
