Flashed my apad RK v2 earlier today to RB5.1D/L the hiapad.com RKandroid_ENG and put it in folder on desktop (Win7 Home Premium 32 bit), D/L RB5.1 and did the same. Switched off the apad, toggled it on, connected the usb to the Netbook (using the usb cable that came with) held the button down, inserted the mini usb into the apad and waited till Win7 detected it. It did but wouldnt allow me to install the driver. So, copied the folders across to my XP drive (dual boot) and rebooted the Netty into XP.Did the same as above and this time got the driver install menu. Run through the procedure, installed the drivers, run the upgrade tool but the device wasnt detected. Then I couldnt even get the device to register. SO I swapped the cable for another I had lying around and hey presto. Re-installed the drivers and First time, device found. From there the update was simples.SO my advice to anyone having troubles is to ditch the usb cable they send with the device and use a different one.......
