Hacking R4i SDHC problem

[Kusan]

Argg..hello, I have an R4i SDHC (r4isdhc.com), yesterday it worked completely, flawless. Today I try to run it and the "an error has ocurred" appears, I know the most possible cause is a 3DS update, which wasn't done since I'm in 5.1.0-11, the flashcard worked on it yesterday...today it won't, I tried using a different SD card but the problem remains the same.

Possible solutions? I remember old R4s needed a little piece of paper on the SD slot to make contact or something, could that be the problem or this is a flawed card? Because as I have repeated: it worked fine, with no problems at all.

Please help D:

Do I have to run the update? 'Cause on the flashcart's site it says that the update is for 4.5.0-10 and this new flashcarts (with the 2013 label) don't need it. As I said it worked on the 5.1.0-11, it suddenly stopped working. I will try to update to see what happens.

Thanks.

If it's not a contact issue then it's likely that the bootloader has been modified somehow (it can happen on accident in normal use in certain very specific situations), in which case you'll want to run the "update" in order to rewrite the important parts of the cart's bootloader.

In many cases, flash carts that worked on 4.5.x still worked on 5.x (5.x did little blocking it seems), so if your cart's site says that nothing needed to be updated you should be good (assuming they're not handing out incorrectly-worded info, which happens since they're all Chinese).

Makes sense, I'm going to try it then. Thanks a lot.

Is it legal to double-post? If not, then I'm sorry. The flashcard doesn't run on the DSi (it isn't updated), so I'm thinking something inside the cart is broken and it's good-bye. Any tips?

The police will come to your house and shoot you in the face.

In my opinion double posts that come later and add more important info (like in this situation) are fine, but I don't run the site.

Anyways if it doesn't run on the DS Lite either and it does the same thing with a different MicroSD that has the right software on it, then yeah it sounds like too much of the bootloader was damaged.

"Unbricking a bricked cart" shows what to do. It's for the Ak2i, but the update method the AK2i used is what most flash carts that came after it use anyways so the instructions will be similar. You will need another flash cart, and to do this on the Lite.
