Hello, I recently purchased a mid m70003 (7") from China, initially it worked perfectly. Once I got home from China I played with it for a bit, and worked fine. Then I went to bed and my son unknown to me had a fiddle with it and had a look at it and tried to install an application from the market. Aparently it did not work, and after this began constantly restarting and going to the android screen after about 30 seconds of use.So now when ever I turn the device on, after it fully turns on and goes to the menu, i unlock it and go to anything (such as browser) after about 30 seconds of using the device it just goes to the android loading screen (the one with Android in silver.) and just constantly goes on this cycle of going to the android screen after 30 seconds of use, thus making the device somewhat unuseable.I'm looking to this forum for help in fixing this device, as I purchased it directly from a shop in China there is no way i will recieve a refund for the item and am pretty much on my own. Please someone guide me in fixing the device.Awaiting your Responses.Thankyou,
