Figure 1: No dictionaries via Notes in iOS

If you delete all dictionaries on your iPhone accidentally or deliberately and hereby no cloud[☁] appears any more after the [Manage]-button clicked in the list, then you need iPhone DFU(Device Firmware Upgrade) mode.

Be aware of the following.

  • Any attempts within iPhone itself do not work such as [Reset Keyboard Dictionary], [Reset Network Settings], [Erase All Content and Settings], adding a few other languages like French, and even [Reset All Settings]! I had tested them all. None of them can bring a dictionary back to your iPhone.
  • [Restore iPhone] functionality via iTunes on your Mac or PC after backing up your iPhone first does not work either!

The latter was suggested by Apple Support (@AppleSupport) via Twitter. There was a long conversation. They looked kind, but failed.

A deep search of many possible combinations of key words of mind leaded me to the iPhone DFU(Device Firmware Upgrade) mode. It is the real [Factory Reset] you expect, not [Reset All Settings] or anything else, even though they are often called [Factory Reset] as well. It would be quite unclear why there exist two types of factory resets in iOS. I say again that the DFU(Device Firmware Upgrade) mode is the real [Factory Reset] you expect.

There are plenty of descriptions of how to get into the DFU mode you can find in web. I just summarize the steps how to get my dictionaries back in iPhone.

  1. Make it clear that you remember the password for your iTunes Account that is linked to your iPhone.
  2. Backup your iPhone. The [Encrypt iPhone backup] via iTunes is my recommendation.
  3. Turn off your iPhone.
  4. While your iPhone is still connected to your Mac or PC, Hold the Home and Power buttons together till the Apple logo appears. About 5 seconds later after it shows on the screen, release the Power button only but keep holding the Home button about 15 seconds. Then your iPhone goes to the DFU mode.
  5. Follow what iTunes says.
  6. Restore your iPhone from the backup you made in the second step.

FYI) In the case that you are using the two-step verification by your iPhone, do not worry. You can receive a secure code during the procedure when it is required.
