Same problem as above, unpacked my new box today t8 v4.
I installed wookie on kodi. When prompted I disconnected power. Then I turned on box and I get the loading screen. Then a blue screen and it stays like it please could any one advise? Do I have too factory reset?
Disappointed as I purchased this box, to replace my T8v2 that is coming back to you soon as not able to update due to faulty SD.
