Wow! I've been tearing my hair out for a long time now trying to get the tablet recognised by the tool. I did as you suggested and found Rockchip Batch Tool 1.5. The 1.5 version of the tool found the tablet first time I tried. Once I saw that the support field of the Rockchip tool wasn't blank I knew it was going to recognise the tab. Thank you so much. It's great to finally get a straight useful answer.
