    Hi guys! first, excuse my bad english.

    A quick explanation: So, 6.3 and lower uses Old keys, and 7.0 and higer uses new keys. Let´s uses, NK (NEW KEY) OK (OLD KEY).

    We need to upgrade real NAND to 7.x or higer to apply the NK so.. why not...?

    1.- Backup real nand (better by soldering because GW sometimes in normal 3ds, not XL, don´t dump as well some special NAND chips..)

    2.-Update real nand to last version, i think, bootrom will be updated too.

    3.- Restore 4.x nand; bootrom will continue updated but we will can continue using the ds profile exploit because we´re in 4.x

    4.- Launch GW 2.1 (or not?) not probably, but is probable that emunand will load the NK title like youtube. Else, gateway would make a new launcher that supports the NK.

    Ok guys.. is probably that ?
    Thanks for your attention!

    No, the bootrom is on the NAND. If you revert to an older firmware by loading an older NAND you will get the old bootrom as well.

    I love theories!

    Question: Since exists, did ever one of these "user-theories" came true / did work?

    Hehe, my thoughts entirely.
    Theories on the internet only come from people of sub standard IQ who don't know what they're talking about, hence the theory, they don't even realize the complexity of the problem they have a theory on.
    ...The irony :)

    Unfortunately for the more intellectual amongst us, the internet gives every idiot a voice, that's great on the whole...just when it comes to "theories"'s one of the negatives we have tolerate.

    get your superiority complex elsewhere, all-perfect being.

    Let's put it this way: if it really was as easy as update->downgrade and it works, the solution would have been found ages ago.

    So either we need CFW or we need a 7.X exploit. Preferably both ^^

    This won't work because boot rom is part of the NAND that you backed up. It gets reset back to old 4.5 when you restore it. The only way to do what you "theorized" is to decrypt the NAND, and go into it's file system and separate bootrom code from the rest and replace it with the newer one. That on top of the fact you might get a blue screen crash due to possible incompatible code. It's like trying to get Win7 to boot by using Windows 98's old kernel. You're gonna have a bad time... :P

    Since you'd need to know the private key of the 3DS you are trying this on, it's a moot point. If you had the ability to decrypt the NAND, you wouldn't need to do this in the first place. At this point I don't see 7.0 keys working until a 6.0+ exploit is found that has the same kernel access that the current 4.5 one does.

    You can't alter the filesystem at all if it's encrypted. Even if you know the specific sectors the bootrom was stored in, swapping it out will cause the 3DS to fail to decrypt it due to multiple CRC checks failing and the encryption means that it needs to be consistent with with the rest of the filesystem.

    That's just another random pipe dream. There's a hacking theories sticky thread...where you not aware of it? Mods/Admins have repeatedly stated that you need to post stuff like this in that thread. Stop cluttering up this section with random theory threads when there's more important stuff to be filling that space. :P

    When has the bootrom ever been on the NAND?
    The NAND is R/W, which would invalidate the term bootROM.

    Yeah another reason why this is a useless thread. Boot roms are typically permanent, thus the 7.0 keys wouldn't be stored there anyways.

    Which is why a old Wii with an exploitable boot rom can't be patched by Nintendo without a hardware revision. If there was such an exploit in the 3DS, it would be a major fail on Nintendo's part. Sure it would be pretty kick ass if there was one, but don't count on it. I would bet Nintendo learned their lesson with the Wii... :P

    Well the best solution would be to find a solution to definitely flash the eeprom with a custom firmware, so if Gateway really wants those new keys, they will be looking for potential flaws in the bootloader to bypass those silly checks...
