Hi all. I've just bought myself a elsse 7" rockchip2818 tablet. It won't recognise most of the apps I want to use, so I wanted to flash it with a more modern OS (it's currently on android 2.2). I can't get the computer to recognise it with any of the programs, adb, rkcooking, rkandroidbatchupgrade or anything. It shows up the disk drive alright, but anything under the hood it just won't find. Just says device not found on ADB, and nothing else. I've tried everything I can think of, and I managed to get it into the recovery mod using ROM manager. But it won't do anything from there either, and there aren't many options to choose from in recovery either. It just won't recognise the device I can't think of what I need to do to get it to work. I've got usb debugging turned on too. Any help would be greatly appreciated. I've read through all the tools and everything and I just can't get it to work.
