pull power cable...  and plug back

restart and update again...   used lan cable...

Do you have any usb connected (pendrive or hdd) while rebooting?

How to reset to factory setting

1. take power adapter off.
2.press pin hole upside down of the box.
3.turn on power adapter and keep pressing the pin hole at the same time.
4.keep pressing pin hole after you see recovery menu on the screen.
5.After you see it ,take remote and go for factory reset option.
After that you will make factory data reset by hard way.
Box will reboot and you must to wait for entering desktop mode.
Now you will have all new sw ,like from factory ,and go again for Ota update menu and it will work.

From my usage, it's almost the same... Only using different launcher...

If you're into modding, try Supercelerons mod. I'm on SV8C rom on my normal GT1 for about 2months now. Super solid, nice launcher, and no hang or reboots.

Using it primarily to casually play hearthstone now lol with some tweaks to reduce graphics as S912 chip isn't that powerful enough for this game to consistently go above 30fps. What a joy playing the game on TV compared to on phone or PC.
