But you don't understand what the guide is doing then. Actually read it. It's based on using fast and safehax, which are only really working on 11.0~ and up right now.
Regardless, the guide has been updated multiple times.
He's on 10.7, he's not going to downgrade to 9.2.0, as it's only risking more of a brick. If he stays on 10.7, he's going to be using a method to get kernel9 access that has not been thoroughly tested and hasn't been made to support 10.7, but has been made to support 11.2. That's why I'm saying he should update. What you're telling him to do, probably won't work very good. It'd be quicker and more stable if he did it through 11.2, but that's your thing if you want him to risk more of a change to brick or whatever.
I misread what you wrote, yeah his best bet would be updating to the latest system and try the safehax+fasthax method on that newly firmware.
When I had 10.7 n3ds I used browserhax dropping connections to the nintendo update servers then I used plaisysupdater to downgrade to 9.2. None of the other sys downgraders would work for me and I had to run PlaiSysUpdater twice as the first time it did most but not all of the downgrade.
Did you use PlaiSysUpdater?
You could use tikshop, then download games directly from the eshop.
install this on fbi using remote install then install through qr code and install the qr code found here https://freeshop.pw/ next google 3ds title keys and scan the qr code through freeshop qr code scanner.
They can say 3ds title keys. They just can't link it. Or they could say that title keys site.
