I have a cloud ibox 2 plus with "tune failed" on all channels and SNR (etc) to 0%. Nothing works. I've check tuner configuration and settings are ok. I didnt use this box for some year but before was all ok. Everthing was work very well. What's happened? I tried this box on two my dish and different lnb. Nothing changed. Firmware: OpenMB 4.0 Cloud Ibox3 2016 Edition by Robijay [751 Mhz]. I have that bootloader, J-CFE-0.5 for clones (I remember) Anyway, i have 751 mhz cpu . I hope to fix that, thank you all.
