Hello, I've been trying to install RxTools according to this tutorial. Unfortunately I've encountered quite unusual issue: When I got FBI on my SD card and launched it via Menuhax it launches properly FBI 1.4.17. I wanted to install FBI.cia from root of my SD card but when I select it for installation I get error message: Install failed! FBI.cia Source: SOURCE_FSFILE_WRITE (0x1c) Module: MODULE_NN_AM (0x20) Level: LEVEL _PERMANENT (0x1b) Summary: SUMMARY_iNVALID_ARGUMENT (0x7) Description: DESCRIPTION_INVALID_SIGNATURE (0x6a) Press Start to continue Does anyone know why it fails? I have downgraded O3DS with 9.2E. Thanks in advance.
