The recommended exploit for system versions 1.0 to 11.3 is [soundhax](https://github.com/nedwill/soundhax), in which case you just have to put `otherapp.bin` onto the root of your SD card.\n\n## Technical details\n\nWe leverage a kernel exploit to alter L1 translation tables entries that were never previously accessed, then run `kernelhaxcode_3ds` which does the rest of the job.\n\n* **Below system version 9.3**: we use memchunkhax1\n* **9.3 to 11.15**: we exploit `sm` then leverage this to exploit `spi`. SPI sysmodule has access to `GPUPROT`, subsequently allowing us to GPU DMA over the kernel memory\n    * `spi` vulnerability has been documented on 3dbrew for years, and hasn't yet been fixed\n    * `sm` vulnerability is an unreported 0day. Fixed in system version 11.16\n    * `safehax` or `agbhax` used depending on version. `agbhax` hasn't yet been fixed\n\n## Testing with Luma3DS\n\nNeed to disable firmlaunch patches \u0026 build without custom `sm` sysmodule if using Luma3DS.\n\n## Credits\n\n* @zoogie: testing and debugging on exotic firmware versions\n* @fincs: exploitation ideas, etc.\n* @aliaspider: memchunkhax code\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftuxsh%2Funiversal-otherapp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftuxsh%2Funiversal-otherapp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftuxsh%2Funiversal-otherapp/lists"}
