Once I did update the system and everything was fine. The first would see a A9 logo and then a robot (android logo) with a progress bar at the bottom.
After the update, the system appeared on-screen information about the completion of the two errors but the execution reboot the system everything worked properly.
After some time and installing many programs the system went a little slower. I decided to restore the factory settings.
I entered the android system settings. Then backup and reset -> Factory data reset.
After this operation, the device sometimes freeze on the string mbox.
I decided to do it again update the system.
The procedure was different than before. Toothpick method worked but the robot (android logo) now displays information such as the "erase", "system update", etc. This happens with every upgrade.
On youtube in which is shown the procedure to upgrade the system does not display subtitles.
Subtitle language depends on the language settings before restoring the factory settings in the settings android.
It seems to me that it may have an impact on the appearance of the image freezes when the device starts.
Is there a procedure to restore the device to its original state to not displayed the subtitles when you update the system?
Thx.
