Pfffftttt brickproof, bricked my o3ds today its still luck based on the otphelper part, did everything as mentioned in the guide got to the one click setup all stages failed injected firm into both emuNAND and sysNAND one stage passed another failed, led to a ineviteble brick, the only thing which has been made better is the otphelper app, before it was much worse when trying to inject the emuNAND into sysNAND, otphelper only saves you because it has the ability to restore sysNAND and thats all it still is dangerous as it will always lead to a brick if all stages fail regardless, so its not a brickproof as people here want to make you believe.
