Hacking Installing A9LH from 9.2, with otp.bin already extracted.

[thewarhammer]

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!

use SafeA9LHInstaller through homebrew launcher to install arm9loaderhax on 9.2, with an existing otp.bin.

https://github.com/AuroraWright/SafeA9LHInstaller/releases
https://github.com/AuroraWright/arm9loaderhax/releases

find data_input_v2 on this page (dunno if I can link directly): https://github.com/Plailect/Guide/wiki/Part-5-(arm9loaderhax)

payloads, firms, and secret_sector go in /a9lh along with otp.bin

Just a thought:
That otp.bin is from is console, right?

Make sure it is and not some that he found from somewhere else, otherwise he will BRICK.

Saying this because if he did the Plailect guide for the OTP, how did he managed to end in 11.0.0-33 without the a9lhax installed?!?


Just wondering...

Maybe he used Decrypt9 instead of Hourglass9 and didn't select the keep A9LH option in Decrypt9?

Thanks, worked like a charm! As I'd always have followed the guide from the start before, I'd rather be sure about how to proceed in this specific situation than make a mistake. Thank you again!

And sorry for not being able to answer sooner, I was at work.

Exactly. I wrote about it before, it was because of a little problem with the guide's PT-PT translation (and the lack of attention from my friend, because the PT-BR translation didn't have this mistake), that at one line said to use Decrypt9, but with it's usage referring to Hourglass9's options.
