Hacking Homebrew Error while dumping NAND. Seeprom error

[MillKeny]

When I try to dump NAND, it gives an error. I tried both via Homebrew Channel and via the exploit website. What is the problem? I have seeprom.bin file in my SD card though, what is that?

---------------------------------------
Writing otp... Success!
Writing seeprom...
Failed to open /seeprom.bin for writing!
Error! -> rebooting...

Run a file system check in the card and also make sure it is enough space left

God damn it, the problem was lock switch on card! I forgot about that thing, thank you!

Then it should have already failed on the otp
