Lumia 635 ATT boot loop

[darkoman4]

So I went through all the install process to get Windows 10 technical preview on my phone. Everything went fine with update to Denim and just about when it got to the point of booting in windows 10 in shots down and reboot. And like that forever. I pulled SD card out and now it boots to some kind of mix of windows 10 and 8.1. I get notification center expansion, but settings are still 8.1. No keyboard is available in any app so I can not sign into my wifi network. OS version is 9941.12.12498.
​Does anybody have any idea what went wrong?

Roll back to 8.1 then try again

Maybe you shouldn't have updated to denim while on a tech preview build?

I restored the phone to factory settings and now everything is fine. Windows 10 is on the phone. If anyone else gets this problem, you will have to restore your phone.

When did AT&T release Denim?

While updating to windows 10 it briefly updated the phone to Denim. Once on W10 it reversed back to Cyan.
