CDA revision that will trick SEUS into Updating W508?

Hey, guys, after unsuccessfully trying a couple of CDA revisions to force SEUS to debrand my phone for me (was a W518A) I finally just went the full flash route with an older firmware (R1EA028) via A2uploader.Then I tried SEUS again, thinking it would update to the latest firmware, but says I already have the latest, and does not give me the option to reinstall.

Anybody had sucess with any particular CDA with this phone, that will force SEUS to install R1GA026? According to the SEUS database, this is the latest American firmware revision for the W508.

Thanks all!

You can try these CDA's:

W508 AMERICA CDF1223-7208 R1GA026
W508 AMERICA CDF1223-6738 R1GA026
W508 AMERICA CDF1224-0448 R1GA026
W508 AMERICA CDF1224-9609 R1GA026

Thanks for the reply, Senter, but I tried each of your suggestions individually, but each got the same response from SEUS, latest software already installed. I did upload them one at a time via A2 uploader, and turned the phone back on each time to let the update take effect before trying SEUS. If I could find the files myself, I'd just flash the phone and be done with it. None of the websites that have firmware downloads seem to have R1G for W508 yet, though.

Thanks again for your help!
