Iphone disconnected problem during backup

Can you make an iCloud backup? If you can, do.

But the idea is you delete apps one at a time, try to back up after each one deleted. The problem is you will lose app data when you delete the app. If it's an app that syncs data with a server (such as multiplayer games, note apps like Evernote, 3rd party mail apps...) or that don't store data that you need, this isn't a problem, so perhaps start with those.

I discovered the cause of my problem when I was looking for large app data

to delete... when I deleted the app with the data the first time backup

worked... so I thought that I might be the size of the data.... when I

installed the app without any data backup showed the same problem.... I

admit it was luck but a more learned intuition would make me look for apps

that have their own storage and can transfer files directly from

iPhone..... if that has ever been the case

Hi. I realize the problem I am facing since I have upgraded my iPhone to IOS10.3.3 is exactly the one described here. My iPhone 7+ disconnects at the latest step of syncing, and the backup cannot properly end. My ipad upgraded also to ios10.3.3 is syncing correctly. This problem occurred right after upgrading my iPhone IOS. So I am pretty sur that it is a bug that happens with ios10.3.3 in some configurations only, as it doesn't happen to everyone.

If it happens when some apps use a large data space, then I don't know why apple sells iPhone with 512GB memory.

I was wondering if anyone had considered to upgrade to ios11 (currently beta4) to see if the problem is solved?

If it solves it, I wouldn't mind using it, as I think beta 4 should have solved the most annoying bugs of ios11 already.

Anyone tried it and could share his experience? thanks a lot.

I have one file over 3.0 GB and it is my music app. How do I stop my music from backing up to Itunes on my PC? I don't need it to but don't know how to make it not backup. iCloud backups work but I don't have music backing up to there.

I would delete all music and check if that solves the problem before asking

about music backup..... it may not be this app or the size of "this" data.

Thanks for the information. I still have the problem on my iPhone 7. It started about 8-5-17. I do backups to ITunes almost ever day and the backup gets about halfway done and disconnects! I will try deleting music another day.

I suggest you look for file manager, photo manager, or document manager

apps that are installed on your device... I guess the problem would be

there.

You are welcome, but I didn't say anything about "size" of data.... I only

mentioned the kind of apps that could be associated with the problem "even

without storing large data"

I tried all the Internet-suggested modalities. None of them worked. My problem is conditional. An iPhone 6S completes a backup, and an iPhone 6S+ does not. Same iOS, same Windows 7 Pro sync PC, same USB port, same lightning cable. Same everything, just two different iPhones. The thing which makes the backup go sideways on the 6S+ ? Where do I start? Apple refuses to support the open architecture FLAC lossless audio codec. The only lossless codec supported by Apple is their own, the ALAC codec. This forces everyone who wants to play their lossless FLAC library to find A) another audio player, and B) another way to get the lossless music into their iOS device. I use the Onkyo products on some of my surround systems, so I decided to use their iOS app 'HF Player'. I also have some mid-to-high tier Onkyo headphones which this app supports nicely. Putting the app in my iPhone causes no grief. It's only when I put an album worth of FLAC music in the 6S+ that it will refuse to backup. And FYI, the message is actually incorrect. The phone does not actually disconnect. I've gotten that message, then seen it continue to move several books into my phone during a sync. New contacts sync, everything actually syncs. Just the backup crashes. If I pull the FLAC files out, the backup goes off without a hitch. The two iPhones are about as identical as one could hope for, Same 128GB storage, same processor, same iOS, same everything but screen size. The 6S backs up and the 6S+ does not if there's FLAC files involved. I'd really like an answer. It previously worked on an earlier version of iTunes and iOS. Something seems to have gotten broken along the way.

Hi again - I've followed your instructions. FYI, "Pause" didn't stay paused in my version of iMazing (no "Resume" option popped up either) - so I let it run all the way and then just used the search bar at the bottom of the console to look for the "no operation..." language, which I found.

There were several instances and I have been unable to find anything by googling the file, or by using a Spotlight search.

All of the file names ended in M^Arias.html

All showed first throw call stack

All showed NSInternalInconsistencyException

All showed Terminating app due to uncaught exception

All showed cphlocalcachedirectory

I confess I don't know what any of this means - if someone reads this & says "Oh yes, I know what to do..." I'd be so grateful if you share! Thanks!

I guess I will remove all the music from my iPhone 7 to see if that fixes it next time I try. I did notice that one of the back-up that I saved that is now in my mobile sync folder is much bigger than the original one I looked at when the backup problem first happened as once the backup went 3/4 of the way through the process before quitting and the sync on that one had seven steps instead of five steps. I had removed the old backup in that folder to my desktop at the time and tried that a bunch of times. I have no way of knowing if this is a full backup and the date of the last back up in Itunes still says the same date, 8/4/17. What is FLAC music and how do I look to see if something is that type?

FLAC stands for 'Free Lossless Audio Codec'. iTunes does not recognize nor will it easily sync it into your iOS device. Typical resolutions are 24 bit / 192 kHz and 24 bit / 96 kHz. It compresses the audio to be a smaller package, but it reinflates it to be identical to the original waveform. MP3, MP4, WMA and other popular codecs are lossy. You choose your level of loss versus file size and just live with the results. For most portable uses, lossy codecs are no big deal; we're listening through earbuds, or in a moving vehicle or it's just background music for dinner. For serious listening on a high res system in a controlled environment, lossless is radically better. If you had a FLAC collection, you'd know about it. Apple will sync their version of a lossless codec, ALAC .. the 'Apple Lossless Audio Codec'. Microsoft has their lossless codec as well. FLAC is open architecture and a universal exchange medium for studio quality sound.

Well I haven't changed my music or added any new music in many months so that can't be the problem I guess unless it does have something to do with a recent update either on Itunes or iPhone...I just know it started after an 8-4-17 update on Itunes as I couldn't update when I tried again on 8-6-17. What about what I have read about the lockdown folder on other sites. Can I delete that folder or empty it and see what happens?

You can copy your music to a directory on your pc ( copy files in the

iTunes transfer pane)... then try deleting the app with the music

altogether

When anyone writes code, it is always imperfect. Updates typically do two things: fix known bugs and introduce new features. Sometimes those updates introduce some unanticipated bugs in the process. iTunes and iOS track each other. A new iTunes release usually predicts a soon to be updated iOS. Whatever coding changes we've had recently, my Onkyo player and it's FLAC files previously caused no issues in a sync. More specifically, the size and method of importing the FLAC files did not interfere in the backup that's part of a sync. In my estimation this is an Apple oops that will only be resolved in a future iOS release.
