hello people i have a tablet Arnova 7H G3 short since it makes when starting a Factory reset. Apps are no longer saved, I only access via the adb console as root. According to other forums is a firmware update help, unfortunately I have found none. Can you help me? I do not want to throw away the tablet. my guess is that it may come from two apps for the first bussybox or Lucky patcher. Please help me I'm really stumped! If please with detailed description please. with the ADB Console I have a little experience.

Thanks in advance
Best regards from Germany
