Hello. I have N3DS E with version 10.3 and I want to downgrade it. I have some questions. 1.I tried to downgrade before and I got an error of missing cia with the same pack file at the first time, which lead to incompatible downgrade. the wired thing is that the MD5 check file is good and also the sha1 and I also checked the pack with SafeSysupdater and it said that everything seems good. is it okey to use those files again? 2.I know there are a lot of SysUpdater kinds, which one is the safest and which one I need to use? 3.Something else I need to know/do/follow to increase the rate of successfully downgrade? Thanks for the help!
