Hello! I got my hands on an old generic China tablet model number F902P it's a 9" tablet. The problem is that i can't uppdate the system. It's done by something called OWL update, but it always says Server busy try later. Is there any other way to update this thing? On system page it says: Kernel-version 3.4.0+ liuhy@gpt-server-sw #29 Thu Apr 10 09:59:03 CST 2014 Version full_gs702c-userdebug 4.2.2 JQD39 eng.liuhy.20140411.091818 release-keys. I'm totaly new to this so please explain very simple for me. If there is a file to download for local update please point me in the right direction.
