Is there anyway to check nand dump. As im guessing its encrypted. Viewing with hex editor shows nothing useful.

Ok, been investigating. I have 2 original backups from before doing anything. Now those hash's match. However if I write it back to DS and then read it back, the hash is different to the original ones. Is this why its not working?

if you write the nand back to the 3ds and start it then read it back then the hash will be different as the 3DS changes stuff on the system every time it boots
to check if the FIRM downgrade process is being done open the original nand backup and the "modded" on in a hex editor and go to the offset 0x0B130000, and make sure that there is some differences, im not100% sure what first offset than changes, but its around 0x0B130005, but side by side there will be obvious changes in that area

I read that some where, however on opening them to compare they look like they are encrypted.

Forgot about you, I'll download and get patched right now.

yeah they are encrypted, but if the FIRM has been changed it would obviously be different regardless of its encryption

Would like to thank vb_encryption_vb & gamesquest1 for trying to help.
Has anyone else ever got freakyhax to work in regard to downgrading?
