I think newly added function : _Z39VerifySignatureUsingSSL_ContentsManagerPhS_S_ is responsible for not working applications on CI models.

yep, new file in firmware at game-lib dir: "game_verify_key.pem"

Downgrade method don't too dangerous for CI+ devices because there is some security mechanism checks the image checksum of firmware. Perhaps I advice you try reflash with new firmware but patched with SamyGO Firmware Patcher. Some users are successfully patched their CI+ firmwares with SamyGO Firmware Patcher tool. Thanks.
