my lumia 640 stopped working after the latest update. stuck in reboot loop.

[WPCentral Question]

on 10 dec 2015 i saw an update for my lumia 640. i downloaded and installed it. first it showed the gear image while installing. after completion it show microsoft logo then windows blue logo. then it restarted all over again. the steps are repeating. i have tried the hard reset option but it leads to the same condition.

If you have apps installed on an installed SD card try removing the card and starting over.

did you hard reset on 10581 (previous) build? There's this loop bug for those who did, you'll need to hard reset thru hardware keys and everything should be fine!

I had the same problem on my 640XL and the solution above solved it!
