@aldostools with this test version continues to produce the same failure.
I tried with other standard CFW without cobra (Overflow, Ferrox and Playerkp420) and the last version of Irisman works correctly.
By deduction the problem is in the CFW Darknet 4.81 Cex that @darkjiros public.
@aldostools Irisman does not work correctly with CFW Darknet 4.81 Cex (no cobra), mamba does not work and the control fan, also always the following legend when opening it:
ERROR: Unsupported firmware or the syscalls are disabled!
Some functions will be limited.
