Hi.

7fg3 not working, found instructions on here, great I thought.

However windows recognises it as an MTP USB Device not a RK29 device and will not install drivers.

Is there any hope or is it total knackered. Cry

Cheers

When you try to do what i said above, try to keep the device disconnected from any power source.
Than, after you do all the steps that i said, connect the tablet to the pc, the screen should be black.

you can find arctools here

and here more info about the app

Thanks for your persistence, will try again tomorrow night.

I don't think it actual goes into flash mode, goes out (black) when you push rest and will then shortly pop back on again.

will report back, cheers

I'm afraid you've totally lost me now, adb?

found adb tutorial but

Extract the files (remembering where you put them), then connect your tablet in debug mode.) Debug mode is not the same as recovery mode (required to flash the RK29xx tablet). You set Debug Mode from your tablet by going into Settings –> Applications –> Development –> check the “USB Debugging” box.

as I can't get anything on the tablet screen, how do I get into debug mode!

Some progress I thought, tried it on another PC and it came up in device manager as a AN7FG3 but no luck finding driver

Through a combination of holding down volume - inserting pin in reset hole and then plugging into USB port at the same time the tablet screen stayed black and device manager found a RK29 device.

drivers were installed from rockchip batch tool and all seemed to be going well, until it reported Device cannot start (code 10), now assuming there must be a hardware fault, unless anyone knows better.

Does not appear in Rockchip batch tool v1.5 under connected devices

Cheers for all the help
