  • yeah !!!!!
  • Got it. Wish could upload a picture
  • Sam - please check you PMs! Please please!
  • K. Replied. Thanks!
  • Mayday mayday! Data and Wifi not working. I may have to do a hard reset. It looked like it installed properly but something went wrong. I cannot activate data or wifi. :(  
  • I am probably the first one who had to wait twice as long as everyone. Well, I did a hard reset and both cellular data and wifi working again. Thanks to backup/restore, most of the stuff will come back. I had already transfered my pictures over to a computer in anticipation of this update, so that I wasn't worried about. Anyway, WP8.1 (finally) up and running... Woohoo!
  • thats why i was not going to upgrade. are you facing any other problem
  • Not anymore. I think during the install, I was taking snapshots of screens. That somehow forced skipping on installation of some files. It would say installing step 12 of XX, and then it would jump to 13. It seems if you don't touch anything, everything goes well. but the installation is not clean enough to handle or accomodate any button presses during progress.
  • When installation reach 60% to 75%, phone shows error (801882d1). Is there any minimum free memory or wifi speed required ? 
  • that's my problem too, it always been an error everytime i tried to update, i have my phone a hard reset but it's still the same..
  • i never experience that one, but try it in wifi conection not over data
  • As per the first announcement the official 8.1 updates will be roles out to current 8 user will be on 31st May'14 right, Then y we have to download preview for developers? When vl be the official release of 8.1 for current 8 users?
  • Hi! I have a question - what happens with Nokia additions - as example Nokia Glance - do they remain after update or dissapear? Thank You in advance.
  • Nokia additions will stay on your phone.  OS updates and Nokia Firmware updates are seperate, if you update one, the other is unaffected.
  • Unless microsoft were to changew something that caused one of nokia's features to glitch out, then obviously that feature would be dead until nokia updated it, but that would be a huge rarity, plus, i think nokia's already updated everything they could without an actual firmware update for 8.1... you should be fine :P
  • Will not install today. Will be waiting for bug report. When safe, then install.
  • will all the apps and games update after installing this update??
  • Yes thet will be there, along with all your apps and data
  • Whoa!! 19 Steps in migrating data -_-
  • At 73% then I had to goto work. Won't let me download without WiFi. Uhhhh. Won't be able to get it until tonight.
  • how much data it consumed 
  • yeah b!Tc#
  • Yeah SCIENCE!!!!
  • Oh sweat baby Jesus!
  • He probably will.
  • Lmao
  • Cant download right now whats going on??????
  • need a hotfix/small updates first
  • Yeah, that freaked me out.  I thought I was getting 8.1 at first.  I had to go do the update again.  Now, I am preparing to install.
  • AHHHHH ITS HEERRRREEEE!!!!! I DON'T EVEN KNOW WHAT TO COMMENT!! WHOOO!!!! :D
  • FU Comcast. You choose a horrible day for an outage in my area :( nothing wrong then an update ready, can't install
  • Downloading it now, doing it on my 925 first.
  • Same here. Lumia 925, from India. It already took 15 minutes in " Migrating your data (Step3 of 6) 65%
  • Completed step one in 40 min...laterz
  • When you say step 1, do you mean when the gears are spinning?  Mine has been spinning for about half an hour now, no text on the screen, a little progress bar that hasn't moved at all.  Is this normal?  I have the T-Mobile 925.  My storage only had a little over a gig free, so I'm not sure if the more used space makes it take slower (by converting the filesystem or something)... but the progress bar has hardly moved (if at all)...
  • its normal  
  • Thanks, yeah it just finished.  The progressbar was basically at 1% for about 50 minutes and then in 10 seconds went up to 100%... migrating now.  I didn't see step 1 or 2 come up at all, but it's migrating on step 3 of 6.
  • I am facing same issue, Is it normal??  
  • Yes this is normal.
  • How is it?  
  • Seems faster
  • Ha!
  • The link does not work. How can Microsoft miss this. :(
  • not for meO.O
  • Im at school and cant use any WiFi to download :(
  • Not sure what I picked up, I checked this morning and nothing. But there was a update when I checked now. So I am updating over data. Not worried, I have 10GB a month to use, since out of my 3 lines, I am the only one with a smartphone, I get it all to myself. Spinning wheels.....
  • I am facing spinning cogs for the last 20 min in the hotfix update. Is something wrong? How long did yours take?  
  • Just wait, mine had not moved for ages then suddenly completed in a minute.
  • Now it is moving. Thanks. I was afraid too much seeing that spinning gears.   Spinning Gears - A Windows Phone Horror Story
  • My 920 is taking a much longer time.. almost 1h with the spinning gears.. but it alsways took a long time for him so I'm confident :)
  • Took my 920 37 minutes to install the first update. I agree, my 920 has always taken a long time to install updates - the progress bar always stops near the beginning, nothing happens for a long time and then it jumps to the end.
  • Shouldn't the gears be touching each other to rotate? =D
  • actuall I sometimes stare at the gears and raondomly make them change direction in my mind. Top turning clockwise, bottom counter clockwise; then flip directions, or make both go right, and lastly both go left. Although I have a hard time making them both turn the same direction in my mind because like you said gears shoudl be touching and logically the should go in agreement with each other. One clockwise the other counter clockwise.   Anyone else do that out of boredom?
  • They go either direction. The gears are really just two images that make it appear as if it is spinning. It is really just rocking to the left then the right.
  • Our brains are wonderous things you are right it is just two alternating images that aren't animated at all yet our brains fills in what it seems to be motion. I wonder if someone who has never seen gears in motion would even realize that they are "moving" in any direction or do they just see the two flashing images.
  • Now, I could tell that this is a long update, hence people making fun out of an image of gears on a phone.
  • My cogs are spinning and YES you are right, think they are goong clockwise and they do. Think anti clockwise and they do. Wonderful, well spotted :D
  • LOL that was bugging me too!
  • yes, I agree. I'm still having my 920 installing the updates, i hope it would not be a troublesome..
  • lol
  • During a hard reset, i had that spinning gear for 2 days!!! Then I had to go to nokia care...
  • my 1020 took 25 minutes spinning the gears.
  • Thanks.
  • Gimme Gimme Gimme
  • Me too
  • And me
  • 24 minutes untill migrating data finished  
  • It seems to have a lot to do with what's on the phone.  We have 3 920s in our household.  Mine has many more apps, e-mail, photos, videos, etc. that the others and has taken an hour to update in the past.  The others are usually done in 15-20 minutes. I installed one update this morning which took 50 minutes.  It then told me I was ready for future updates including 8.1.  I'm downloading that now assuming it will be another 50-60 minutes. I can't wait--its certainly worth a little phone downtime for an update as massive as this one!
  • I just now unisalled a lot of apps to try to speed up the update to the 8.1... Hoping that it will help..
  • How do you download it over data?
  • I too am trying to figure out how to download the update over the air. Can't seem to find the proper settings to allow it. On Bell in Canada, not sure if they have restrictions.
  • You can't. Need Wi-Fi to download update. I am currently in travel and have to wait till I reach home. Then only I can update from my home Wi-Fi.
  • It was only the 2MB one. :( Have to wait till I get home
  • Upgraded to 8.1 Nokia 520 in 8.37 minutes what a phone
  • how yaar i didn't get the update on 520 after doing preview fordevelopers step....pls help  
  • Skip school!
  • YEAH!!!! I plan on doing that :P
  • insufficient battery, :(
  • U should have been ready for such occasions
  • i was just way too excited to check my battery level
  • I know right! I had my battery 100%, Screen Cleaned with Extra Special Screen Wipers, All the BS Apps removed from my phone. And a Cozy room set up for just me my phone and Cortanaa!! :S
  • lmao awesome

  • It seems... Faster... No, seriously. The update download and install are going really fast, I just downloaded it within a minute and it's now just about to reboot to install Edit: shit, that's just the pre-update to prepare your phone...
  • Yeah, I got that too. Damn they're really teasing. At least it's finally here. :D
  • ok, i think there is a first update and them there is the real update Wp 8.1
  • Right. The first one was only for "preparaations" I guess. Now downloading the major update.
  • hahahha - same thing happened to me, but still stuck in 0% in the WP 8.1 update..
  • O no. Now I'm going to be late for work. 
  • F*ck work, 8.1 is here!!!
  • I would agree to this, but co-workers are looking forward to Cortana.
  • How big is the file?
  • The file is about 2MB as usual. It will extract and then reboot the phone to do the install.. that's where the spinning gears come in.. (and where I am now..)..
  • 2mb? Cool story bro.
  • They really need to work on that progress bar during the 'Gears of worry' time. It's been stuck at what seems to be 5% for more than 5 minutes now, but I read online that it then suddenly jumps to 100%. Stressed..
  • No!!! Its huge! First one is the minor update. Major update will be after the restart.
  • not much! I just have to wait 3 minutes!!!! And my internet connection is not so fast
  • Bah, that's just an update which allows you to get the main update.
  • What size is it?
  • its nearly 400mb
  • 920 just restarted to install 8.1 :) Did a 'check for updates' on the off chance it was able to update, and something started to download :P Getting way too excited about this update to be an average person lol.
