W10 10.0.10166.0

Same problem on Lumia 625, but solved...
Maybe it was again the overheating problem: clicked to install update, then put the phone to the fridge (it is not a joke!). The downloading had finished, the preparing to install finished. After restart i put back the phone to fridge while installing. now everything is fine... :grincry:

Its same with me

What build are you on? I'm planning to test windows 10 on a Lumia 520 for the first time just to get a feel of the OS. As far as I know the slow ring is currently on build 10166(that's what the update screen shows me) which is older than the build 10536 offered for the fast ring.
Is 10166 more stable than 10536 on the Lumia 520? Anyone who's tested it on the 520 please comment.
