    So I am right know in process to setup A9LH on my old3DS and now I want to downgrade my 11.0 emuNAND to 2.1, but everytime I try to downgrade it fails and says :

    fs.cpp:117: Result: 0xD8E0806A
    Failed to write to file!
    Did you store the update files in '/updates'?

    Yes I stored the files in the updates folder...
    One thing I noticed is that the checksum from the downloaded zip file "2.1.0E(Full).zip" doesn't match the checksum from the Plailect guid... But I used the link in this guid!
    Is this maybe the error? Where can I get the right 2.1.0E(Full).zip?

    I really need help :(

    Thanks for reading my problem!

    you must redownload the files if the checksum doesn't match and delete the previous one
    also, what cfw are you using right now?

    Never mind xD This was my fault. I compared the md5 checksum ^^
    But this doesn't help me pretty much, because the downgrade still fails again and again... :/

    Try using devmenu_2x.cia (do NOT use any other version!), I've had a lot of good luck with it. Go to the updates folder and import all cia's with L + R + A. Wait a good while for it to finish.
    Then immediately, don't forget this, go to *0004013800000002.cia and select Start + Y to finish the native firm installation.

    *It will be 0004013820000002.cia on new3ds.

    DON'T FORGET to verify the downgraded emunand in OTPhelper before you go ahead and copy it to sysnand.

    I'm going to ask what might be a dumb question but did you place the updates folder on the root of your SD card? Your error is saying it can't find the files because /updates means it needs to be on the root of your SD card.

    Yes I did...
    Everything went fine until NATIV FIRM.
    NATIV FIRM installed succesfully but after this this error appeared.

    Read steps 10-11 and then the Overview of steps at the top of Part 4.

    Did you format your RedNAND/emuNAND twice?
