@everyone - there are no bricks using SafeB9SInstaller and boot9strap, and I bet you to proof me otherwise. Everyone who disagreed in the vote didn't actually brick, but didn't pay attention in one way or another. These "bricks" are fully fixable by quickly consulting
@Plailect's troubleshooting page (or by paing attention in the first place).
This may sound overconfident to you, but I actually do know what I'm speaking about (obviously). The only way you'd brick is by malicious intent, i.e. modifiying boot9strap.firm and boot9strap.firm.sha before install. You'd have to modify in a very specific way, one that will never happen by file corruption, and one that no noob with a hex editor will manage to do accidentially.
