pre9otherapp

Otherapp payload which can be used on firmwares earlier than 9.2 to launch an arm9 payload from the sd card directly.

Note

The otherapp payload which is produced by this repo can be used on all regions and 3ds consoles but works on all between 1.X and 9.2

Usage

The otherapp can be used with soundhax to launch an arm9 payload such as safeb9sinstaller. The otherapp looks for a arm9.bin on the root of your sd card.

Steps

  1. Get the soundhax file for your console and region
  2. Get the arm9 payload, safeb9sinstaller in this case
  3. Download the otherapp.bin from the releases page
  4. Put all the files on the root of your sd(for safeb9sinstaller, just copy the arm9.bin from the zip)
  5. Launch soundhax If everything goes correctly you will be in safeb9sinstaller, this might/might not work on the first try.

Technical details

I have incorporated an edited version of svchax(memchunkhax) and brahma(firmlaunchhax) to gain arm11 and arm9 execution. So we first use memchunkhax to gain arm11 execution, then we map the arm11 and arm9 payload and then perform a firmlaunch. On Pre 4.0 firms we use usr2arm9ldr to gain arm9 code execution
