I am trying to update my iOS version without loosing data. Initially, I was trying to update from iOS 10.3.x to the latest 13.4.1 (iPhone SE). Because I have not had much storage space left, I downloaded the latest iOS manually as an ipsw file and tried patching it with iTunes. All went well for a bit until I got an error message from iTunes saying something like "The iPhone could not be restored. An unexpected error occurred (14)." Now, the iPhone is in Recovery Mode. I cannot effort loosing my data and still hoping that I can somehow just update it and it magically works again. All my research just lead me to the various recovery tools e.g. EaseUS, minitool, dr.phone Toolkit that do not really help me. I am using iTunes version 126.96.36.199 and OS X 10.11.6 El Capitan
4 Days later and I have tried every single possible solution from the net without luck.
- USB connection (different cables, ports)
- Re-download IPSW file and making sure it is not corrupted
- Different computer(s)
- Different iTunes versions
- Tried the update over and over again (error 14 triggers every time)
- Tried mounting the iPhone (see) to clear space (not possible in Recovery or DFU mode, internally everything gets encrypted to one big file once the phone enters Recovery Mode)
- Tried useless third party apps: dr.fone, EaseUS, MiniTool, iPhone Backup Extractor etc. -> These "Freemium" Software cannot do more than iTunes. They are using and abusing the desperation of people to buy their overpriced products. They pay $$ to appear first in Google search results.
- Tried useful third party apps: RecBoot, 3uTools (see below, very useful tool but Windows only), iFunBox,
- 3uTools powerful tool. Can try lots of different things, like update to beta versions, repair drivers etc. That is probably your best all-in-one solution.
- Called Apple AASP (they don not have a magic tool either)
- Jailbreak in DFU mode with checkra1n
- Downgrade (requires either more than one IPSW-file still signed on ipsw.me or you have saved the right SHSH2 blob)
iTunes error 14 is likely to be caused (see)
- Due to a bad USB cable.
- Due to an error with an firmware upgrade.
- Due to a lack of capacity in the iPhone.
- Due to an unstable network connectivity.
- Due to an outdated iTunes.
Error message from 3uTools
Flash error explanation: AMRestorePerformRestoreModeRestoreWithError failed with error: 14
If it is not a hardware error, you may consider:
1. Connect another genuine cable to the rear USB port of a fully powered case 2. Repair drivers with the iTunes Utility in Toolbox and flash again later
The problem in my case is most likely a lack of capacity on the iPhone so during the update the system got corrupted/ "bricked". There is no known solution/ workaround to me to keep the data (without having a recent backup). I have to factory reset my device (wipe all data) to get it working again. So yeah, backup your files kids!
