iTunes: How to Fix Error 29

If you see error 29 in iTunes, you cannot restore or update your iPhone, iPad, or iPod touch. We'll show you how to solve the problem.

Fix error 29 in iTunes yourself

Restart: First switch your computer and your iOS device completely off and on again. This removes small problems in the cache.
USB: Connect your iOS device to the computer using a different USB port. Replacing the cable can also help.
Update: If an outdated version of iTunes is used, this quickly leads to problems. Therefore, carry out an iTunes update.
Software: If communication between iTunes and iOS device is disrupted, this can also lead to error 29. Briefly issue all self-installed anti-virus programs and firewalls.

Error 29 often occurs after changing the battery. If Apple notices the change, the process is blocked in iTunes. Either reinstall the original battery or use a higher quality model.
A jailbreak can also be responsible for error 29. Because even this change in the system does not like Apple. The problem can be solved by removing the jailbreak again.
If none of this helps, you can set up your iPhone, iPad or iPod touch again. If you create a backup with iTunes or iCloud beforehand, your data will not be lost.
