Guys I met a problem. I have a japan N3DS version 10.3, and tried to downgrade. I followed every instruction steps(especially deleting the special .cia for japan N3DS), after the device auto reboots, it shows a message in below, same as in english"an error has occurred, blablabla". So I powered it off and reopened it, but it keeps showing everytime I started it. Not possibe to access recovery mode also. I have also tried remove the storage card, format the storage card, no help. Any suggestions?
