+Your `00000001.sav` and/or `otherapp.bin` files may be misplaced. Ensure that `00000001.sav` is in `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `0017c100` -> `data` and that `otherapp.bin` is on the root of your SD card.
+
+If your files are in the correct locations, re-create the save using the [PicHaxx Save Tool](https://3dstools.nhnarwhal.com/#/pichaxx), then place it in `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `0017c100` -> `data`. Ensure that the file is named exactly `00000001.sav` and that you used your console's `movable.sed` to create it. Re-download the latest release of [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/releases/latest), place the `.bin` file relevant to your console from the `otherapps_with_CfgS` folder to the root of your SD card, and rename it to `otherapp.bin`. Do not add the `.bin` extension if you do not already see it.

Re-generate your `movable.sed` from [Bruteforce Movable](https://seedminer.hacks.guide), then re-create the save using the [PicHaxx Save Tool](https://3dstools.nhnarwhal.com/#/pichaxx) and place the resulting file (`00000001.sav`) in `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `title` -> `00040000` -> `0017c100` -> `data`.
