Those who are stuck on spinning gears, try this:
1) plug in your phone
2) do the soft reset (with the power button and volume down)
3) at the Nokia screen press Volume Up, Volume Down, Power, Volume Down (one at a time, quickly)
4) do the same sequence at the carrier logo screen (not sure which if it would help as my phone is unbranded)
5) let the gears run for about 10-20 minutes. If it doesn't finish up, do it at least 2 more times.
The above worked for me when my phone got stuck on gears after portico and after hard reset, though its not going to work on the 0x80188308 error lol. Hopefully the next update they roll out addresses it.
Anyone notice any UX changes?
