我知道我很奇怪，因为在看到新的错误信息后我会感到一丝兴奋 iTunes的。大多数人呻吟，并且认为它需要一天的时间，但我可以从中发布新的博客文章，并希望能帮助一群人！所以没有进一步的...

今天早上我正在测试一些iPhone驱动器清洁软件并恢复已清理的备份。在这样做的时候，我得到了这样的信息：

考虑到我的iPhone USB电缆有电热带将它们连在一起，我首先假设我的USB连接到电脑出现故障，拔掉了所有东西，吹上了所有东西，然后再将它们连在一起。当这没有帮助，我注意到我的手机实际上仍然连接到 iTunes的，我意识到“因为iPhone断开连接”意味着更具体的“因为iPhone与恢复服务断开连接”。由于我故意编辑我的备份（以减小文件大小），因此我可以推断出我正在恢复的备份可能存在问题。

如果您看到消息“ iTunes 无法恢复 iPhone，因为 iPhone 已断开连接。 “这可能意味着iPhone恢复过程在iPhone上崩溃。可能的原因和解决方案：

您的iPhone需要重新启动。由于我们遇到了崩溃的过程，首先尝试的最简单方法是重新启动设备。这将修复任何可能导致iPhone崩溃的简单问题。
您的iPhone备份实际上已损坏。不幸， iTunes的 iOS支持损坏备份不是很好。尽管我们做了一些工具来帮助！您可以使用我们的修复备份 Decipher Backup Repair 以便您可以恢复已修复的备份 iTunes 。或者，你可以从iPhone备份中保存数据 Decipher Backup Browser 。您也可以留下评论，我们可以讨论我们如何提供帮助！

I need some help! I backed my iphone 6s up to my itunes. I then tried to update my itunes software. For some reason, my phone went into recovery mode. Now, I am trying to put my restore that is on my itunes back on my phone. The first 4 attempts it would run for an hour and then say "Cannot restore the phone iphone is disconnected. On the 5th attempt it just ran for about 8 hours and the time kept increasing. Apple support is telling me to just delete it all and start over but I REALLY need my data for work. What can I do? Thank you.

Kelly HW 四月 4, 2016

Hi I'm trying to update a friends iPad 2 for the first time some it was bought, it needed the update because all the apps wouldn't run because the os was out of date. I plugged it in to my laptop and connected it to iTunes and tried to run the update. It ran as normal and then as the apple sign with the loading bar appeared on the screen of the iPad it repeatedly disconnected and reconnected until an error appeared on the laptop screen. I tried repeatedly and used different USB ports and the charger cable is just out of the box so that's not the problem. What do I do as the iPad is now wiped with no os on it and won't run at all, thanks

Varun Bhasin 十二月 12, 2015

hi.. i am facing a similar situation ...need help badly..need the data back

Nick 十月 10, 2015

You said it was a free trail but I didnt even get to finish my de bugging...

Zoki Todorovic 十月 10, 2015

hi kelly i am also trying to back up my iphone 6. have tried all these options and a few different ones. Get to the end pretty much then get the message. This is driving me nuts not sure what else i can do

Kelly HW 十月 10, 2015

Hi Zoki!

This sounds quite familiar to what we've been hearing from people wanting to *make* a backup as well, rather than restore one. The suggestions that seem to be working for most people lately are 1) put your iPhone in airplane mode and 2) to make sure you don't have a lot of pending app updates on your iPhone.

(If it seems like shortly after plugging in to iTunes a ton of updates magically are needed, let me know.)

Feel free to send me an email using the "Contact" link way at the top of this page and we can dive in to your specifics.

Zoki Todorovic 十月 10, 2015

Thanx i did get it to work eventually had to delete old back up restarted my Mac and re booted the phone and it worked. But do need to instal some major updates but have no internet ATM. Will monitor if this keeps happening and will let you know. Thanx again Zoki

Greg Oliphant 十月 10, 2015

I had the above error. And after 3-4 new iPad resets, deleting of backups, uninstall and re-installs of iTunes, one time iTunes kicked out a new error 0xe800000c, which i read is a bad cable error. Not sure why this error didnt pop up the multiple other restore attempts. I also read that sometime usb3 can be an issue. Fact is - I removed the new cable, used my old apple cable on a usb2 port and presto everything worked fine.

Georgina 九月 9, 2015

I am trying to swap from my 5S to a 6S I have backed up my 6S to my iTunes multiple times, deleted old backups in iTunes, changed cords, changed ports, restarted iPhone and computer.... Keeps working for 10 min and then "disconnecting"

Kelly HW 九月 9, 2015

Hi Georgina!

You've backed up your 5S and are getting the "disconnecting" when trying to restore the 6S, correct? If you'd like to contact us, you can do so from our support page: https://deciphertools.com/s... where we may be able to help more directly.

Brandon Beck 九月 9, 2015

After exhausting all of these solutions and failing each time, it decided to go full retard in my attempt to restore my files from my iphone 5 to my new 6s. First, I deleted all other backups aside from the one I needed. Then, create a new backup of the 6s and go into the folder and delete ALL of the data but the leave the folder intact. Next, go to the folder with the data you actually want and copy all of them. Paste in the new backup folder->win->eat ice cream

Kelly HW 九月 9, 2015

Hi Brandon,

Interesting solution -- did you replace every single file in the "new" backup folder with the versions from your iPhone 5 backup? Or did you leave some?

Nups 七月 7, 2015

Hi Kelly,
I have tried restarting, changing USB port and it is still giving me the message of iPhone disconnected. I have send an email on info decipher email IS. Thanks

Kelly HW 七月 7, 2015

Hi Nups,

I just wanted to make sure I replied here too for our readers', since we have been emailing back and forth. The "disconnected" error message can sometimes be caused by USB issues, and sometimes by errors in the backups that cause the restore process to "hang up" on iTunes.

Ashik Iqbal 六月 6, 2015

Hi,

I am having same problem. But in may be another way, I have iphone 5s (A1530), when i am connecting it to itunes its showing an update file of iphone 6,2 but when i am connecting it in DFU mode its starting downloading Iphone 5,2 file. I am too confused why its happening. In both cases update is terminating during backup. and its some time showing Because Iphone disconnect some time showing error code 32 (which is not included in apple error list in apple support page!!!) can you please help me? now my iphone is running 8.0.2. and i am in huge trouble. I can not find my "Mail, Contacts, Calender" in setting.
I can not add any accounts, Please help me out.

Thanks,

Ashik

Kelly HW 六月 6, 2015

Hi Ashik,

Send us an email to info@decipher-media.com, and let me know what OS you are running on your computer. We'll grab some of the log files and see why the connection is getting severed.

Hi Kelly, I have encountered the issue on itunes "could not restore the iphone because the iphone disconnected" .... And I downloaded the free trial of your decipher backup repair and repair my backup file... and it stills not working! Is that because I needed to pay the license to do advanced repair for my iphone or my file cant be fixed?

Thanks a lot !

Kelly HW 四月 4, 2015

Hi June,

Yes, you'll need to register the program -- the program will then walk you through a few more steps and then tell you it's time to try the restore :)

Scott K 十一月 11, 2014

I just wanted to let everyone know that I was having the exact same issue with iTunes disconnecting and I tried moving my back up so on and so forth. I have an iPhone 5 using iTunes 12 on Windows 8.1. I tried the suggestion of plugging the usb cable in to a usb 2 port instead of using the usb 3 and it worked!

bradclarkuk 九月 9, 2014

Im getting the message just when trying to do a backup through iTunes to my computer - can't seem to get it to complete. Im using an amazon lightning cable. works with everything else, syncing, charging etc

Kelly HW 九月 9, 2014

Interesting. We could try deleting or "hiding" your previous backup from iTunes. Since iTunes does an incremental backup (building on the previous backup) it's possible that a problem in the existing backup is causing this message.

Do you have a previous backup listed in iTunes (Preferences -> Devices Tab)? If you're comfortable deleting that backup you can do it through iTunes, but if you'd rather just hide it, you can rename the folder of the backup and then iTunes won't use it as the "primary" backup to build from. If you need instructions on getting to the actual backup folders, let me know what OS you are on (Mac or which Windows) :)

bradclarkuk 九月 9, 2014

Hey Kelly, thanks for taking the time to reply. I have deleted all the previous backups and reset the lockdown folder etc - nothing is listed in the preferences - could this be due to having a developer beta of ios8 already installed? I am currently trying to do a backup via iCloud but it will take forever and a day.

Kelly HW 九月 9, 2014

Hmm - I definitely took backups of our iOS8 beta phone a lot, but maybe yours has something goofy going on. I have two more thoughts about what we can try:

1) If you want to grab the iPhone Configuration Utility, we can use it to grab the log file from the phone while it is backing up. We can see what the backup agent process's real complaint is.

Windows:
http://support.apple.com/kb...

Mac OSX:
http://support.apple.com/kb...
(The download page will mention a newer version available for Mavericks, but for our purposes, this version is easier!)

The log scrolls like crazy, so it's annoying to copy & paste directly from the program. I usually save to a text file. If you want to email us the log file you can use the email address info AT decipher-media.com and I'll take a look at it.

2) iTunes may not report the backup existing, but there might be one sitting in the backup folder anyhow, being a problem. If you want to go look manually:

On a Mac your backups are in /Users/your username/Library/Application Support/MobileSync/Backup
(Open Finder, hold the Option key, and select "Library" from the Go menu to get to your user's Library folder.)

In Windows, the fastest way to get to your backup folders is:
- (Windows 7 and below) Start -> Run -> type %appdata% (with the percents) and press return.
- (Windows 8) Search -> type %appdata% (with the percents) and press return.

From Application Data, navigate to Apple Computer, Inc. -> MobileSync -> Backup.

You can match your device identifier with the backup folder name by clicking on the Serial Number field in iTunes (which will switch it to your device identifier.)

Removing the /var/db/lockdown/file where file is the same .plist file name as the most recent backup in the local Library also helps.

Catalin Lungu 七月 7, 2014

After many attempts, I restarted the iPod manually as you suggested in the first step, and then restore from previuos backup went smoothly. Thank you Kelly! (This happened after I installed iOS 8 beta 4 and then went back to 7.1.2)

Kelly HW 七月 7, 2014

I'm glad the advice helped!

Dimz 七月 7, 2016

how do you reboot?

Kelly HW 七月 7, 2014

We're seeing a fair deal of traffic to this page from people searching for this error dialog. Are the suggestions helping you? If not, leave us a comment so we can figure out some other fixes to add to this article!

Gaztastic 十月 10, 2014

I'm having similar difficulties to some, when backing up when I get to the end i.e. 7/8 during the back up,I get the iPhone is disconnected error. There are similar threads on Apple support but none of them have worked for me yet. Below is a list of what I have tried:

I'm using an iMac on Yosemite, with iTunes 12, IOS 8 on a 4s, all up to date.

I have deleted all back ups through prefs in iTunes

I have turned off all WiFI

I am not using a Hub or USB 3

I have tried backing up to my Mac which I normally do

I have tired backing up the iCloud as an alternative option, same error.

I have tried a different cable to sync with that works on my wife's set up (same as me only Maverick / IOS 7 & iTunes 11)

I can not find the MobileSync folder (perhaps Yosemite has a different folder structure?) to change the back up file.

Any other ideas? I don't have a back up at all anymore?

Kelly HW 十月 10, 2014

Hi Gaztastic,

Thanks for commenting -- definitely the first thing we should do is find that MobileSync folder so we can look for anymore backups to erase.

In Finder, select the Go menu up at the top of the screen. If you hold the option key, a menu choice "Library" should appear in the Go menu. Select Library, which will take you to your user account's Library folder (as opposed to Macintosh HD/Library.)

In this Library folder, navigate to Application Support-> MobileSync-> Backup. If there's no other backups to delete/rename/move, let me know and we can move on to looking for other reasons the phone would complain during the backup.

Gaztastic 十月 10, 2014

Hi Kelly

I followed your instructions and found the backup folder, renamed it and moved it to the desktop then tried a back up. The same error occurred, when looking in the back up folder an identical back up folder had been recreated which appears empty (folder name: ec658dc7ebadc596f406115f0ce29e3866b39148)

Thanks for the speedy response.

Gaz

Kelly HW 十月 10, 2014

Hi again Gaz,

Thanks for the followup. So iTunes/the iPhone are indeed having an error just when creating a fresh backup. (Usually, the error is due to a problem with the existing backup being updated.)

Can you send us an email at info AT decipher-media.com or via our support page http://deciphertools.com/su... (both go to the same place :)) We should collect the logs while your backup is running, so we can see the complaint. If you want to dig up the existing log files that may already be on your computer from the last couple tries, here is how to do that on Windows:

Windows 8: Go to Search and then type %appdata% (with the percents) and press return/enter. A file browser window will open to the Application Data folder.

Windows 7, Vista, XP: From the start menu, select Run. In the run box, type %appdata% (with the percents) and press return/enter. A file browser window will open to the Application Data folder.

From there, navigate to Apple Computer -> Logs.

Do you see any files in there starting with “asl” (dated when you were doing the restores?) Feel free to send us anything you have, and I’ll sort it out. Usually the log files do not contain personal data, but you are of course welcome to review them prior to sending them to make sure!

For the life of me, I still can't find them on my Mac. But we can just collect the logs directly from the phone in either case too.

Gaztastic 十月 10, 2014

Hi Kelly

I'm also on a Mac, I will send you an Email so you can let me know how to proceed with logs.
