The second time I turned on my new tablet it will only boot to the "android" page and will not go past. I contacted the seller and all they would do is send me what they called a 'refresh' file, which I believe is an image file. They would not tell me how to load it when I can't do anything with the tablet (won't reset with usual button combos and it doesn't have a reset). Can anyone help?! Thank you! More info if it helps: It is an Allwinner Model Q27B, CPU Model A13, CPU Type Cortex Q8, OS Android 4.0.4.. I'm so frustrated I could scream! The vendor that sold it to me is no help at all! Any help is greatly appreciated!
