    I was discussing with a friend (@mrissaoussama) about how people could extract a bricked NAND from a Wii using bootmii and change files, to fix the NAND.

    It isn't so simple to add random files to a 3DS NAND, but..

    Say you have a bricked NAND on a9lh with no NAND backups.

    You also have another hacked 3DS using updated sysNAND a9lh.

    Can't you make a CTRtransfer out of the brick, transfer it to an emuNAND of the target system, fix the files using sysNAND's files, then CTRTransfer the working emuNAND back to the bricked system? Or are we missing something?

    The steps would be the following.

    1. Open Decrypt9 on the bricked system, and create a CTRtransfer file using the bricked nand.

    2. Transfer this bricked CTRnand to an emuNAND of another 3DS.

    3. Using GodMode9 and sysNAND, copy the files that caused the brick (for example, a bricked HOME Menu on a American 3DS) a content folder named 0008f02 from sysNAND.

    4. Copy the file/folders from sysNAND and paste it into the bricked emuNAND. The emuNAND would now work.

    5. Finally, create a CTRTransfer file from the emuNAND.

    6. Open Decrypt9 on the bricked 3DS, then install the working CTRtransfer file. The system should now be reverted to its state before the brick.

    I don't think that's possible... Correct me if I'm wrong, but also wouldn't a 'unbrickmii' like tool be possible from the Wii?
    This tool would force the Wii to read update data from a disc to reinstall IOS titles.
    Maybe possible with a arm9 payload to find out which title is missing/corrupted and restore it but who knows

    If your bricked how are you going to system transfer?

    I didn't say system transfer. I said CTRtransfer, which is a Decrypt9 tool. (which you can access through a9lh)

    If you have a9lh and no backup, you can CTRTransfer assuming the brick is only in CTRNand, this has been known for a while.

    Did you read the entire post? It was about fixing a brick in CTRnand by using another system's files and transferring the ctrnand back to the original system.

    U can't use Nand files from another system. U can try to do the 9.2 CTR transfer to your sysnand.

    The Plailect guide has CTRNANDs for those situations, if the problems is in the 3DS CTRNAND it should get fixed by using those in Plailect's guide

    End result, your flashing 3ds A to 3ds B which has 3ds A nand info, leading to a brick.

    You need the xorpads..

    It would be easier to just dump ctrnand from the working system and transferring it to the bricked one

    Again. CTRtransfer, not a nand flash.

    No, without using Decrypt9's tool, the CTRNAND would still be encrypted.

    So then dump it using D9's tool? I don't see what's so hard about this.

    Still, if you don't want to lost info from your actual nand.

    That's uh
    exactly what I said in OP

    we can extract the xopads.

    Your missing the point here, its like beating a dead horse.

    You need the xorpads from bricked console.

    Without them your screwed.

    Than fix said brick?

    Here, I don't think anyone here gets it.

    You cannot normally "swap" any parts of NAND between two systems without using Decrypt9's CTRtransfer tool.
    No, Decrypt9 makes the CTRnand usable on other consoles. The new a9lh guide was based off of this.

    you wont lose your info, since this is a clean NAND(IIRC, i havent tried the ctr transfer so idk)

    KEEP 'EM ALL YOURS BACKUPS, ONE ONE YA SHALL NEED 'EM.

    KEEP BACKUPS OF YOUR CELL
    OF YOUR CONSOLES
    OF YOUR PASSWORDS ( WRITE DOWN IN A SECRET NOTEPAD AND/OR AN AES ENCRYPTED ARCHIVE FILE).

    Sorry, about the caps, but its past time for people learning that backups exist because they are worth.

    I think everyone here is confused.

    @astronautlevel, it seems to me that you think this post is about simply transferring a CTRNAND to a new system. Er, no. If system A's CTRNand is bricked, transferring it to system B wouldn't change a thing.

    Mission not complete.

    I would be using Decrypt9's tool to transfer the broken CTRNand to a working system with working files. Then, I'll use the files to fix the bricked files on the NAND while still keeping encryption good, then transfer it back to the original system (using CTRTransfer again), fixing the brick.

    @Tenshi_Okami, the main point of this is to avoid as much data loss as possible. Using one of Plailect's would be the equivalent of having a freshly formatted console.

    @vb_encryption_vb, you don't need xorpads to ctrtransfer. That was the point of mentioning CTRtransfers in the first place.
