I'm trying to factory reset my Android tablet but I can't get it to work. I have tried to press power and volume down to make the device go to boot configuration but it only shows the Android logo and doesn't give me a any options to choose to wipe all data or restore it back to factory setting. My tablet is a A710, I don't know the brand.
I want to reset the device to factory settings because I can't remember the pattern to unlock it. I have tried searching and tried everything I can, such as install Android Sdk Tool, run Android Multi Tool but the device cannot enter adb shell and I get an error. My android device has not got usb debugging enabled so it's more difficult.
