Unable to flash MK802IV AP6210 8GB using RKAndroidTool.exe

[MisterMic]

Hi, I am completely unable to flash my device (MK802IV AP6210 8GB)

I start the device in the bootloader and it seems to detect (screen 1), and then I press run and it always fails on this part (screen 2):

I have tried this on multiple usb ports and on multiple computers (laptop running vista, and desktop running win8). All attempts fail with this same message.

I've also tried both 1.20 and 1.24 bootloaders.

Each time, I can reflash it to stock using RKBatchTool.exe just fine, but the video frame skipping issues in the stock ROM make this device unusable for me.

Okay, so I got it to work by unchecking the parameter checkbox and flashing the device like so:



Then I unchecked everything else and checked the parameter box and ran a second pass.
