Ok! I dowloaded my F firmware. All the zt-update content I moved to the sd card root. I pressed "minus" volume +power and rebooted, but the firmware remains the same. What am I doing wrong? Any chance to have a video showing how to upgrade firmware? Thanks!!
Don't use the minus button. As soon ad you start the tablet press the camera button. DON'T TOUCH THE SCREEN AT ALL. it will tell you to puss the camera button 1 or 2 more times. Then the tablet will take control.also make sure you have the update files in a folder named zt-update not just thrown in the root.
We have tested, and the ICS works well on Zenithink C71, and McBub.com already sell the Zenithink C71 with the Newest Android 4.0.3 ICS, the customer who has the android 2.3 os, can download the firmware here to update: Zenithink
please notice your SN number before you do the update.
