Well... an update.
I never changed my registry back to list the HTC as my device model. I'm still showing Nokia 735. I have received the anniversary update, currently I'm listed as running 14393.67
I wish I could help y'all more, and I wish no one had problems getting the original instructions to work. Naturally, persistence is key, get ready to upgrade, restart, start over, get frustrated and do it all again. I've been a windows mobile user since the beginning, and I mean the very beginning, some sort of Motorola flip phone, so I'm used to this.
Remember that we're way off the beaten path right now so you have to try try and try again. If this wasn't my daily, I'd start from scratch and see if I could help more.
Keep posting your results, good bad and otherwise and maybe through all this we'll get everyone rolling on redstone.
Cheers
PS. benj1091 deserves all the credit here for posting the original path to upgrade. I was just foolish enough to do it on my daily!
