hey, I'm having trouble getting my q89 recognised by the RK Batch Tool, i've plugged it in, held down vol+ and the power button, but i'm not having any luck - even tried the driver assistant and everything.
Any ideas?
This is the method I used to flash my GPD Q89 on windows 8.1 and it worked. The only difference is, I was able to install the drivers beforehand and the computer would recognize my GPD, so did not need to do steps 1-3. Even with the drivers installed the RKBatchTool would not recognize it until I edited the config.ini in step 4. Hope this can help.

This solve the drivers problems in Windows 8.1:
1) Connect your device to the computer in flash mode.
The computer will say ?USB Device Not Recognized?.
2) Go to Device Manager and you will see your device listed as ?Unknown USB Device (Device Descriptor Request Failed)? in ?Universal Serial Bus controllers? section.
Now in ?Universal Serial Bus controllers? section you should also have ?USB Root Hub??s (might be several of them).
3) Click through them and find the one that has ?Unknown USB Device (Device Descriptor Request Failed)? in the ?Power? tab (should be next to General).
4) Right click on that ?USB Root Hub? and press ?Disable?.
Now you should have a small arrow pointing down on the USB Root Hub icon and the ?Unknown USB Device (Device Descriptor Request Failed)? should have disappeared.
Now you have to go to the folder where the RKBatchTool is located on your system.
Find the file "config.ini" and open it.
Find the section where it says:
LOGFLAG=TRUE
#SUPPORTLOWUSB=TRUE时,扫描支持full speed usb设备,默认只支持high speed usb设备
SUPPORTLOWUSB=
Write TRUE next to the second ?SUPPORTLOWUSB=?
It should be like this:
LOGFLAG=TRUE
#SUPPORTLOWUSB=TRUE时,扫描支持full speed usb设备,默认只支持high speed usb设备
SUPPORTLOWUSB=TRUE
Save the file and open the RKBatchTool as usual and you should see the green square in Connected Devices.
Now you will be able to flash the rom.
