UPDATED 13 sept 2017. Unbricked with acekard ntrboot. I complete more then 100 NEW 3DS OTPLESS INstall. With 1 unic brick it was downgrading from 11.0. But no OTPLESS BRICK. Today my first case. Like i said its more then 100 NEW 3DS dont with OTP LESS. I started using UNSAFE then when SAfe was release i just used that. I was updating it always when a new release come out. But i stoped updting SafeA9LHInstaller because it was working verywell. Didn't expect to happen. Like always i run SafeA9LHInstaller 2.X. Asked for press "select" and then black screen. Console will light on (blue) but screen still black and nothing happens. Tried everything. With ou wihout MicroSD. Well. I just updated my files to SafeA9LHInstaller v2.6.6 with A9LH files from Plailect guide. With SHA Hope never happen again. But my problem its. I alredy bricked 2 console. Someone perform a hardmod for me. But i had NAND backup. But now i dont have. I just do have the "F0F1_N3DS.BIN" from DSiWareHax downgrade. So what can i do? I can't believe after more then 100 tries, 1 console bricks. The microSd was the same. The operation and files was the same. It's not the MicroSD or files inssue, because i alredy did today 2 consoles OTPLESS with same card and its working verywell.
