Its all has to do with the timing of the exploit eexecution. Has nothing to do with what firmware your currently on. Also the nand type could be a factor, the sd card brand as well. But it all really boils down to the exploit which is not 100% stable.ok that is just lame why didnt the software fail on other firmwares, I was using all the same files, and on both 3ds systems that were on 9.9
the downgrade went exacly the same way with the same error, so lets just agree to disagree ok I dont care either way.
