As far as i remember, j-tagging fixes the 8882 error & bad flashes. I had the same power issue as above but managed to send it back before the new software was released and just received replacement today Not much use to me now though cause sports and movies are gone.
The power issue wasn't just with clone boxes. It was with genuine boxes also. Either way, no fix for them.
Yes but not the ones that got invalid box, and that prob has now been fixed with the release of the V1.12.
