my brand new nexus 5 just came back from replacement and worked flawlessly for a week or two,
The thing it that after the update, i had this strange "Stuck at turning wifi on bug".
I tried everything i saw on all the forums i managed to find and google usually tell users to replace their devices.
The thing is i just flashed the radio-hammerhead-M8974A-184.108.40.206.17 Radio, and at reboot i was able to turn wifi on.
The main problem now is, that the device freeze 15 second after succefully showing me nearby wifi networks, and then proceed to reboot.
I think many users are in the same situation, has someone managed, somehow, to patch the error ? I can't even tell if this is a software or hardware related glitch, but more and more users are experiencing troubles and i think google should talk more about it.
