Homebrew (REQUEST) How to modify a Ninjhax QR Code to run on a different firmware

[cokacommando]

Hello,

As some of you may know, I've recently acquired a 3DS on firmware 7.2.0-0U, and was hoping to exploit it. After reading this thread (https://gbatemp.net/threads/how-can-i-hack-1-0-0-0u-3ds.394976/#post-5616896) I was wondering how to modify a Cubic Ninja QR code linked by Normmatt (https://i.imgur.com/7Q35Tuy.png) to run on the above firmware!

Cheers and thanks in advance!!!

Try to run an 8.x or 9.x qr code and see if it worked. I was able to install on an 8.1 console using a 9.2 qr code

Freezes at 70% sadly

The problem is I have no access to the web browser...

EDIT: I apparently need someone with knowledge of ASM/ROP/xploits if at all possible...

I could have sworn that @yifan_lu wrote a tutorial explaining how to upgrade a 8.1N3DS to 9.0 or something but I can't recall if it worked on o3ds or on 7.1
