    Hi,

    I was trying to follow this guide to the letter
    https://3ds.guide/

    After the CTRNand steps I boot perfectly into 2.1.0 but when I was copying over the NAND backup to my PC I noticed that the files in the SD:/CTRTransfer/ are listed:
    2.1.0-4E_ctrtransfer_o3ds.bin
    and
    <serialnumber>_nand.bin.sha.

    Does this mean that there where no proper NAND backup made in the process?

    I went to http://2xrsa.3ds.guid and it seems to have worked.

    If I press select while booting I get into LUMA settings but I cannot boot into firmware or mount CTRNAND.
    I cannot restore the <serialnumber>_nand.bin cause it's not in the folder.
    Any options here?

    I have the OTP saved.
    I have another hacked identical New 3DS XL of the same region. Any chance I could use that one to save the day?
    Make a decrypted NAND backup on my other 3DS and make some magic with the OPT of this problematic one?

    Also after restoring the 9.2 CTRNAND image as suggested by proflayton123 i can't see the the actual CRTNAND partition get any larger. The image is about 1gb and the partition is still about 700 something.
    I compared this with my other New 3DS XL on the latest firmware, and that CTRNAND partition is 1GB.
    So I tried backing up the ctrnand_full.bin from my working 3DS to the non-working one following official instructions:
    • Transfer CTRNAND images between systems: Transfer the file located at S:/ctrnand_full.bin (or E:/ I:). On the receiving system, press A, select CTRNAND Options..., then Transfer to NAND.
    (https://github.com/d0k3/GodMode9).

    And it's still showing up as 700 something MB and giving me the same error.

    Im not sure whats going on here
