Hi - I have the AOC all-in-one 24 inch Android tablet. You mentioned that Kingo worked for rooting your 22 inch version. I've tried Kingo with a USB cable connected from my Windows PC with Kingo to the micro OTG port on the AOC tablet. However, Kingo can't connect even after I check all USB debugging. The cable was a standard USB A to USB micro type I use with my other smartphones. Was there anything special needed on the Windows PC for a device driver so Kingo can see the AOC device? Or are there any special steps you took? Thanks so much for your advice.
