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!
