Hello. I have a Gigaset QV830 tablet which is use by my older daughter and haw taken quite a few falls. A few days ago the tablet started to freeze right after booting. I did a factory reset an then it worked ok for a day or two. After that it started being unresponsive if the screen was turned off. As long as the screen was on everything was ok. If it timed out.... I had to reboot it by pressing the power button for 10 sec. Yesterday i went into the stock recovery menu and did a factory reset form there. Nothing changed. so I figured I should try to format the cache. The tablet was stuck formating for about an hour so I rebooted it. From then on, when it boot I get the Gigaset logo and right after that it shows the android robot with a blue line passing over it.... and thats it. I stays there forever. I tried pressing the power button with volume + or - but with no luck. The outcome is always the same. Is there anything I can do?
