Hi people, I'm going through something new to me: A friend of mine screwed up the A9LH installation and ended up with his 3DS on the 11.0 FW. I already donwgraded it with the System Transfer method (I guess he's lucky I have two 3DS's) and downgraded again to 9.2, but here's the question. He wants to install A9LH, and have the otp.bin already. Do I need to redo ALL the steps to install it? Is there another (faster, please!) method to install it? Thanks in advance!
