I tried to update automatically before. Then it become brick. It was just trying to boot but after a few minute reset with boo---p. After long time trying to contact seller, I found this forum. Then I re-installed 1480 and working fine. Then I tried update.zip for 1623 and had same problem of booting. Anyone saw same problem? Good news is I can always reinstall 1480 bad news is no updte.
The best information that I have says that 1480 is not an official update release. If your tablet came with 1170, try pressing the "Reset" button on the bottom edge of the tablet. If it resets to 1170, then you should be able to get the current automatic update 1561. Then try my upgrade method at: http://www.androidtablets.net/forum...factory-upgrade-native-system-update-app.html
