Sorry, this is more a downgrade issue than hard mod issue as title suggests. Ok, so I hardmodded my new 3ds xl and ordered the proper sd card reader to dump the nand, I dumped it 3 times and the md5 and sha1 hashes matched on 2 of them, so I proceeded with one of those 2 dumps. I ran through autofirm and it evenutually was written to the nand on my system, it says the writing was completed OK, but when I goto restart my 3ds after unplugging the sdcard, I get a blue screen with the "signature failed verification" error code. This happens still when I try to write back the original nand. My question is, what are some possible reasons for this? I feel as though if it were the soldering that I would have never gotten 2 dumps with matching hashes that were exact same size (1.84G). Is something wrong with my writing?
