Same here, happens for me in Android as well, I've tried loads of things with no luck, I have found though I can turn the box on with your TV remove if you have CEC enabled....
So, is a problem of the p212 platform?
i tought 2 solution:
1 - Rii i7. If i buy this remote, can i turn on the box? if yes, is a way...
2 - remote controlled Socket...
@ kszaq : your last devel workink like a charm on Scishion V88Pro ( a cheap p212 platform). But, with this
remote, i cannot turn on the box after total turnoff or suspend. Only remove energy cable... ...
