ok this is a follow up on my post from earlier. i was having issues with upgrading - Treo Pro SprintPCS/Win 7/WDM - Was having issues when the tri color screen came on and WDM would disconnect and i would have no luck. Tried a bunch of steps that I read on here. This is what worked for me with the HSPL and the 6.5.1 ROM upgrade.
1. First I didn't have to change USB ports or restart laptop
2. right when the SPL tri-color screen came up and WDM would lose connection then i unplugged the usb cord from the phone not from the laptop
3. I would wait a second and plug it back in.
4. After that it was smooth sailing from there.
5. Now I had to do that on both but once I tried that when I got home and had a chance it worked the first time.
Just wanted to say thanks guys for bringing these out and will be donating for your work,
everyone needs to donate something if this worked! Keeps these guys going for the Treo's we need more modds and hacks like i had when i owned my HTC phones.
