HW - G1 FW - 7.11 (Orange gui) Region - India
I'm trying to upgrade my firmware to Blue White gui from this link - ftp://ftp.d-link.co.za/DIR/dir825%20(new)/firmware/G1_BlueWhiteGui/
But when I try to upload the file onto the router it keeps saying "Invalid image file. Please select the correct image file...". I've tried factory resetting and IE, FireFox & Chrome browser but nothing seems to be working.

That version may not be compatible.
I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this.

We find that phone contact has better immediate results over using email.
