Here's my problem:

Whenever I'm trying to use the "FileSystem Tool" in A2Uploader, and press C on my phone (while it's turned off) my phone turns on.

I had no issues with my w910 on Windows XP. Now I'm using Windows 7 with the latest A2Uploader, I'm getting this issue. I have installed the necessary "Gordon's Gate" Flash driver to no avail.

What am I doing wrong?

Remove drivers and install seus. Then connect your phone and it will install the drivers.
Now you should be able to work with a2uploader!
This worked for me!

Hm, I tried that but it's still just turning on the phone :S It's entering USB Share mode or whatever it's called.

It works perfectly with SEUS though. It even gave me a message about a new firmware (finally). Took Vodafone quite some time to put out new firmware.

Could you maybe upload your A2Uploader version to see if that helps?

I'm using the 22-09-2009 version, nothing else..
But here you go, good luck

I've just tried the "FileSystem Tool" and it works with your A2Uploader version. Turns out I had a somewhat older version from a site where it said it was the latest :S

Yeah you had the non CID53 version.

That's the most logic explanation. Thanks a lot for the help guys!

Good you've got it working now!
