I had updated my Lumia 920 running 8.1 with Lumia Denim (was also running Preview for Developers) to Windows 10 Mobile build 10080 a couple of days ago. This was the first time I had tried a Windows 10 build on my phone and was running into several issues, like a never loading Start Screen etc and very (VERY) sluggish performance along with continuously crashing apps.
I assumed that maybe the update had gone wrong and decided to bite the bullet and reset the device (I had never even once reset it since I had gotten the phone in late 2012) despite the fact I'd loose everything on the phone. But even after several hard resets (both from Settings > about and via the Power, then Vol. Dn exclamation mark screen) the problems with the 10080 build remained.
So I finally decided to give up and go back to 8.1 using the Recovery Tool, and it installed Lumia Cyan on my device which I then updated to Lumia Denim via Settings > phone update. I hadn't installed Preview for Developers this time. (I also learned the hard way that if you don't choose to restore from a backup during initialization, that last backup gets overwritten with the new configuration and is lost forever).
Now today, I again decided to give 10080 another shot since the phone is starting from a clean state. I installed Windows Insider app and enrolled in the fast ring, after updating, instead of getting 10080, I ended up on Windows 8.10.15116.125 which happens to be Update 2/GDR2.
The part that's troubling me is that when I updated to 10080 a couple of days ago, I went to 10 build 10080 straight from 8.1 Update 1. But this time, why did the phone decide to stop at 8.1 Update 2 in between. The only thing different this time is that I haven't installed / enrolled in the Preview for Developers.
