Derrek has given some clearer instructions on how to use SigHax Installer. New SigHax Installation Do not try this without a Hardmod! Copy "arm9loaderhax.bin" onto your SD card Copy a chainloader firm (such as B9S) to the root of your sd card and rename it "target_firm.bin" Put it back into your 3ds Press A a bunch of times SigHax has been installed Old Post As of writing this, 11 out of 18 users have bricked from using SigHax Installer 0.1 9 out of 21 users have bricked from using SigHax Installer 0.2 2 out of 460 users have bricked from using SafeBS9Installer The obvious solution is to just use 3ds.guide. Sighax.com is in beta, it has a rushed release. It shouldn't have been released early, which was the cause of these bricks. "But the bricks were probably caused due to user error, they wouldn't release something which was unfinished!" They were not caused from user error. Having seen the installer, there is very little room for user error. Old SigHax Installation This is wrong, do not follow this guide, or you will brick! Copy "arm9loaderhax.bin" onto your SD card Copy "sighax_installer.bin" onto your SD card Rename "sighax_installer.bin" to "target_firm.bin" Put it back into your 3ds Turn your 3ds on Press A a bunch of times SigHax has been installed/Your 3ds has been bricked I fail to see how user error could be made. The only thing I can think of is if you forgot to rename sighax_installer.bin, or had a file in the wrong place, in which case it wouldn't make any changes to the nand at all. There is no way to brick from user error with sighax.com or 3ds.guide. The sighax installer will cause bricks!
