ROM Hack Where is cfw stored?

[TychiUK]

Hey guys,

I have a broken 3ds, wont turn on, and i'm thinking i need to replace the main board. I'm just wondering where the CFW would be stored on the console. If i change the main board will it remove the CFW? Ideally, i'd like to fix the DS and reinstall everything back onto it.

Cheers

B9S is on the internal NAND of the 3DS. Replacing the mainboard means:

• You lose B9S.
• You lose access to the installed games. The contents of the “Nintendo 3DS” folder on the SD essentially becomes garbage data. Replacing the mainboard is like a complete different console.
• If you did not backup your saves with JKSM or Checkpoint it becomes hard to impossible to recover them (depends).

What makes you sure the mainboard is defective? “Won’t turn on” can have a lot of reasons. Can you describe a little more what happens, when you press power?
Does the blue light come up and fade out? Do you hear a sound?

Basically, my top screen went black about a year ago, it happened quite late at night so i impatiently tried to fix it, making the issue worst. It's got to the point now where there are a few damaged ribbon cables and i've decided to try and fix it again. I think at this stage, i need to find a pre owned DS and either use that, or gut one for new bits inside. A ribbon clip also broke off the mainboard, so the speaker ribbon cable would not stay in the console.

I've worked out that the parts im sure i need would be £46 all together, which isn't too bad i guess

Your best hope in salvaging your SD card data is buy a fully working, used 3DS system (of the same model) and swap the motherboards.
