Ok, some small remarks to be made how to get the FactoryTool flashing the C67ML.
1. I was stuck in the boot with the animation. No way I could get it into some recovery/fastboot state. So when you follow the instructions on prepping the FactoryTool (selecting img, tick the demo box, selecting Restore), nothing happens when you press Run. The animation still continues to spin.
3. So I pried the backcover open using the nail of my thumb. Be careful when splitting the device halves as a wire is still connecting the two sides.
4. I attached the USB once more and the blue USB symbol is shown again, but with the wrong type.
5. The trick is indeed shorting the SanDisk chip with a small screwdriver and make it reboot again. Take a look at the attached img file. I've marked the spot where the pins are located. The device needs to reboot and you will see the blue light go off and on again. The device will now just reboot and try the previous upgrade and will fail again.
6. Now open the tool, do all the prepping of selecting fw image, restore, demo tickbox, oem image, and select the usb port in blue with the Msc state. Now press run.
7. We will now reboot the device using the pins, but you need to apply pressure on the CF slot so the backbutton is pressed against the surface the ereader on. You also need to have the powerbutton pressed. So apply pressure with one hand holding the screwdriver, press the powerbutton so two buttons are pressed. Now short the SanDisk chip.
8. Take a look at the FactoryTool screen as the USB port will immediately have the
Loader type and the prepping of the ebook will start. This will take a couple of minutes. At some point the Tool will say it is finished and you will see the backlight come on, indicating that the ebook is rebooted. From this point you are golden.
