Hi all, I have the 550 firmware too, although it doesn't say so on the webpage. I don't even have a Plusnet account anymore so i'm suprised its still up. When it does eventually get deleted tell me and i'll host it elsewhere.
The firmware is at
www.leedsdig.plus.com/E5D057_GC0S.ab5 The checksum is E946727CEB34C56AA27F80820A278EAB, Use the checksum program at
http://www.irnis.net/soft/acsv/ to check you have an uncorrupted copy of the file. Burn the firmware to a disc and follow the instructions below, they're different to the ones on my site. No need to use a dummy file with this firmware,
Feel free to ask any questions,
Sasquatch
