By mistake, I applied the 250 update again to my X7. Before that, the box was working well. After that I've been experiencing lots of problems in several aspects, there is a lot of flickering on my tv, the wifi sometimes responds very slow it is the same for an ethernet connection, most of the apps when installing or upgrading say "this app may not be optimized for this device". Some apps misbehave so I decided to reinstall according to the procedure outlined by Villa in this forum. I have made it 3 times with no luck that is the malfunctions persist I also have the feeling that the computer response is slower than normal. I even downloaded the update again (x7-rk3188-250.rar) for the 3rd update. The apps still send the message "this app..." upon installation but they in general work well. Nothing else has changed, it is the same tv, the same cables, etc. I am lost, can someone help me? I will appreciate it very much.
