Download either:
this if you have Android 5.1 firmware v1.0.7 - 1.1.0 currently installedor
this if you have Android 7 firmware v2.0.3 currently installedUsing an unzipping app (7zip, winzip etc) extract the update.zip file from the download archive to a USB pen drive.
So you have a USB pen drive with a single file on it, called 'update.zip'.
2. Insert the USB pen drive into any USB port of Q10 Pro.
3. With Q10 Pro turned off, use a paper clip or pen to press and hold the the pinhole UPGRADE button on the back of Q10 Pro (next to the power port).
4. While keeping the UPGRADE button pressed, turn on the Q10 Pro.
5. Q10 Pro will show either the Android 5.1 droid logo (5.1>>7 version) or the Android 7 coloured circle logo (7>>7 version).
6. When you see the droid/circle logo you can release the restore button.
7. A progress bar will indicate update progress. Do not turn box off or use the box/remote during update!
8. When update is complete the box will automatically reboot.
9. First boot will take 3-5 minutes. The box will reboot into new firmware. Allow boot to complete.
