My GS9000 was bricked from a bad firmware update. I was able to read through the Russian forum and figure out how to re-flash it.
First download the Directusb program from
http://dashcamtalk.com/dod-gs600/
You need to install it on XP computer but I read that people did get it to work on a Windows 7 machine.
Next is to download the firmware files from foxoffer.com
You need to hold the left arrow button and connect the usb to computer. The computer will try and find new hardware drivers. I selected automatically look for drivers. It will install Ambarella Evaluation board drivers.
After drivers are installed, disconnect the usb cable and push the reset button on the GS9000. This step is very important because without pressing ther button it will not find it again.
Now press and hold the left arrow button and connect it to pc via usb cable again and you should hear the pc connect to the camera.
Now open the DirectUSB program and hit connect to see if it see's the GS9000
At the top, select Direct USB driver a2s_1Gb and memory frequency 216 MHz.
Click on erase flash and wait for it to be done
On the download tab look for programming firmware and select choose on the right.
Find the flash firmware that you downloaded and unzipped and you should look for the .elf file and not the Yahama.bin file
Make sure that the verify is unchecked. Very important.
When programming the led will flash blue. That is a good sign
It will say:
"Wait firmware programming ..."
Done!! "
Press the RESET button on GS9000, without waiting for any other messages, such as "Firmware Programming Success" and "AMBA Device found" or "... not found". Then wait 5 seconds 3 ... and take out the cable from the USB-ports!
Now, the device can turn the button and see all the familiar "red Mercedes". And now, the device can turn the button and see all the familiar "red Mercedes".
The device is not operational yet, because it has only a repair elf
Then turn off the camera
Format and copy over the yamaha.bin and the other elf. On the sd card. There should be nothing else on the card
Turn camera on and let it do the flash update and when it shuts down remove the sd card and delete the two files.
Do another reset and reinstall the sd card and power up your camera and you should be back in business.
A special thanks to the Russian Forum for their help.
