The title is my frustration summarized . The Mi Box was functioning properly until a week or two ago when it received an update. It was a little laggy but still usable. It would freeze in standby occasionally and I would have to pull power and plug it back in. I did a factory reset after the Oreo update just because it always seems to be a good idea after a major update was released.
I got home from work on Friday and went to go on YouTube and the TV read no signal. I pulled the power and restored it and when it tries to boot it displays the initial Mi Box screen and just sits until it eventually turns off. Using GoogleFu, I found that holding the "OK button" and "back" button when restoring power allows you to get into the boot loader to clear cache, factory reset, etc. I tried to clear cache to no avail and than did a factory reset. It worked! or so it seemed. It worked for less than a day, frooze and had to pull the power again. Now I am having the same issue where it just sits at the Mi Box screen when its initially plugged in.
If anyone has any suggestions or recommendations, they would be greatly appreciated. I am currently using a Playstation 3 to consume media and this is less than optimal. FirstWorldProblems.
Thank You!
I don't have an answer for your issue but I am currently experiencing the exact same problem. I did the same steps as you to try to correct the problem and it worked for one day, then back to the MI Box screen. That is where it currently is at.
