My Q10 Pro box is currently on CFW 5.1.1 (build 1.1.0 by pcristi). The problem is I cannot revert to Official firmware 5.1.1 (build 1.1.0) by flashing the official firmware 1.1.0. The fixing droid logo appears, but gives "Error" and resets the box.
Similarly, I cannot upgrade from the CFW to Android 7, using the upgrade instructions (i.e. by flashing Android 7 2.0.1 --> 2.0.3 --> 2.0.4). Upgrading from the CFW to 2.0.1 already gives "Error" and resets the box.
Can somebody please help me? I can't seem to undo this CFW 5.1.1 (build 1.1.0 by pcristi)!
[Solution]: What worked for me is that instead of only powering off and powering on the box, I totally unplugged and re-plugged the power cable of the box while holding the reset/upgrade button on the back!
