Hi Does the chip s905x support emuelec 4.0 or 4.1 or 4.2
I need to know
No I cannot help you.
First of all, that device is not supported. Supported Devices · EmuELEC/EmuELEC Wiki · GitHub
Second if your IP was blocked there must be a good reason.
And third the API keys are blocked on the site, not on the device.
