I apologise if my earlier post was a bit abrasive.
@Popesuperb you said in a post last night, you 'presumed' openatv 6.2 was flashed
I think this is your problem, you can't assume anything, the box could be only partially flashed with a corrupted download
If you are indeed on the same network, (box and laptop/PC) AND you have a fully functional openatv 6.2 on the box, there is no way you can't access 'Terminal', which means either it's not flashed or the network is not connecting box and laptop together
Download a
new openatv6.2 download (not the one from last week)
put it on a freshly formatted stick
flash as normal
then follow infinity installation instructions to open webif and use Terminal in the normal way
