Hello, this is my first post here so I apologise if I make any mistakes. I have an Allwinner A33 tablet (at least that's what it claims to be) which I purchased from the British Tablet Company on Amazon. The model number is L701. When I switch it on it sticks on the Allwinner Android KitKat 4.4 screen (the last stage of booting) and will not budge. I've tried all suggested combinations to try & get this tablet into recovery mode, but nothing works at all. It just does a normal boot and then sticks. I also tried ADB but my PC won't recognise it when I plug it in via USB, it just doesn't appear at all. Is there anything I can do to get it working again? I really hope someone can help, thank you!
