Hi, I got my first tablet from ebay: 10 1" Google Android 4 03 Tablet PC Capacitive 8GB 1g DDR3 HDMI WiFi 3G Camera | eBay It has android 4.0.4, kernel 3.0.8+, model number U168. The reason I bought this its build in ethernet jack, which I need to connect to router sometimes. Now, I want to root this device. Update android and maybe flash with custom OS. If I load a new OS, can I still use the ethernet? The seller did not provide any software, links or manual. So I am not even sure how this tablet is called Thank you for helping out here.
