An error occurred installing IOS 10.2.1

I'm having a similar issue. Only my messages are being deleted, not my pictures. Now my text messages aren't showing in chronological order. I'm receiving the same error when trying to update to 10.2.1

My pictures just came back this morning, but I don't want to jinx it. My texts are not back, but the same thing as you - they are not in chronological order. If I text someone, the most recent text doesn't appear at the top.

I've been having this problem too! My phone deleted all my pictures (more than once) and then tried restoring them.

My phone runs so slow. I'll open up the lockscreen and sometimes it will freeze around 5 minutes, it freezes up when I try to open any app and then, sometimes, my phone will crash and restart itself.

I'm trying to update it but it just keeps saying I can't.

I'm having the same issue!! I'm so glad it's not just me. I've updated iTunes and tried everything! My iPhone 6 won't even connect to iTunes. It wont sync. It's. wen driving me crazy. I hope there is a solution soon!

I am having the same issue. I thought I needed to upgrade, because pictures were taken however when I open them from the albumn or try to send them via text....it is a grey box. Then I had all my text messages disappear, even though my storage says they are still there. When I try to update, I get the error message.

I am also having trouble with this- I tried to update it via my Mac aswell but I kept getting the same message 'unable to verify' because my phone wasn't connected to the internet even though it was.

As a result, not only can I Not update, but the phone keeps freezing, the emails keep crashing and my pictures won't show up. :( I'm a bit frustrated...

So after updating Pokemon Go.. still crashes and it started crashing less frequently in other apps too albeit infrequent.

Eventually I gave up, made sure my iPhone was backed up (I do backup to the iCloud)... did a full wipe of the device

"General -> Reset -> Erase All Content and Settings".

Took a day to restore all my data and.. RESOLVED!! Yes 4 realz. No more crashing at all..

So I've been digging and from what I can deduce, the update messed up system files when there was not sufficient disk/flash space. Unfortunately this is the ONLY way I was able to fix it.. I tried the "Erase All Settings" option but no such luck.

Anyway.. Its been 3-4 days of using it a lot with PokemonGo too.. no crash at all.

PS.

Scouring the net I've read that iTunes backup, while less bandwidth intensive seems like it may migrate issue. 2ndly if the backup & restore still doesnt resolve it.. there is only one other way.. i.e. back up media, wipe device, reinstall all apps (pain 😟) and then restore media. Thankfully I did not need to do this.

I'm having the same problem! I've tried resetting the network settings, resetting the phone over and over, freeing up space, deleting all my most used apps and it's just not updating! Apple, please sort this out so that we can update it from our phones and not do it through a computer which is so much more long winded. It's even affecting my battery :(

My phone also won't let me update; my texts all deleted and when I began texting again, the messages didn't appear in chronological order; and my phone flashed all of my pictures as if they'd been deleted before they immediately reappeared. However, in addition to all that, last weekend, I went to text someone back and my iMessage app crashed. It's been spottily crashing every time I go to text someone back since then. I thought updating my phone would help, but I'm unfortunately unable to update, as each time I plug my phone into my Mac, my computer won't recognize my phone. I'm not sure what to do. I just updated my Mac, so hopefully that will make it possible to plug in.

FINALLY!!!!!!! After many many months of not being able to download the update and running into the same exact issues that are mentioned in this thread. I was able to download and install update 10.2.1 via ITunes and being connected to my laptop. Thank you so much for help on this thread.

I also have the same problem, but not only with this version of iOS, I had a problem with some previous 10.* updates. And I think it started when there wasn't free space on my iPhone and it cleared something

I have my pictures totally disappeared as well, but under the storage i could still see their existence. I have to reboot the iphone a few times to see the pictures slowly restoring back but as i have about 20k pictures, it took **** long a while! Not only that, it will reboot by itself and start from 0 pictures many times. The sub albums were all gone, all pictures were only in camera roll album, selfies, burst etc. I quickly deleted many unused app to free up the space to about 1GB. I have never had this problem before. Also, i cannot seem to login to my icloud after this. I initially thought this was due to the fact that i have yet to install 10.2.1, i was so wrong after reading all your replies. Apple, do something.

On top of the exact same issues you have listed I can not make in-app purchases on ANY apps. Yes I've logged out of iTunes Store, deleted apps, shut down phone to clear it, add app back, log back in and still same issue. All of these issues are quite frustrating and wish Apple would fix.

Same thing happened to me. All my text messages disappeared. My pictures disappeared then reappeared. Text messages never came back. Ever since then I have not been able to install new update.

I have had similar problems. Still not able to install update.
