Error 29 might also be about security software:

Check for hardware issues

Try to restore your iOS device two more times while connected with a cable, computer, and network you know are good. Also, confirm yoursecurity software and settings are allowing communication between your device and update servers. If you still see the alert when you update or restore, contact belyvn.com support.

thanks for your reply,

i have no problems with the connection, the update fails after the restore is done and wants to install the actual update, on my iphone" s screen its at more or less 60%, its checking the software, and then it goes to install the update and i get error 29, i doubt it has anything to do with my connection
