if you have an sd card with redNAND, it may be possible to fix it. you'd have to use sdio, op, to get the slc, then flash it with a hardmod. it should work, but your system will revert back to that time. sdio won't get you the otp.bin. the rednand nand dumper doesn't do otp or seeprom from what I remember. wait, nm, I think you might be screwed, because you need to use nandfixer on the slc, since the nand dumper misses about 16MBs. iirc, you need the otp.bin for that. sorry.
