I have been able to downgraded my New3DS to 9.2. I formatted a new emunand with Gateway launcher, and I can boot rxTools with Browserhax. While I'm in emuNAND (RX-E 9.2.0-20U) I started again Browserhax in order to start FBI.3dsx. But I can't install any .cia. Tried first with the FBI.cia and then another .cias. I got this: Install failed! FBI.cia Source: SOURCE_AM_START_CIA_INSTALL (0x13) Module: MODULE_NN_OS (0x6) Level: LEVEL_PERMANENT (0x1b) Summary: SUMMARY_WRONG_ARGUMENT (0x8) Description: DESCRIPTION_INVALID_COMMAND (0x2F) Press Start to continue. Any clue what I got this?
