I am trying to downgrade from iphone 4S to iphone 4. Most importantly is the contacts and text. I ran a backup job of the iPhone 4S in iTune on macbook pro and try to restore it onto iphone 4 but NONE of the apps open. The apps look like its open but after about 1 sec it stop. There are tonnes of apps I am trying to preserve. I have try reset the setting on the iphone 4 after the restore. I have try deleting the apps and then download it from App Store but still not working. I power cycle the iphone also but nothing works. Any suggestions?
Basics from the manual are restart, reset, restore.
Try those.
Your contacts will be on your computer in whatever program/service that you have beenn syncing with your iphone. Just sync them to the new iphone.
I am not following the first part of your recommendation. Are you saying that I have to restart the iphone 4, reset and restore. If so that is what I have done with the phone but it did not work.
Reset= hold down home and sleep/wake button for 15-20 seconds until the apple logo appears on the phone. Then release and turn the phone back on.
Once it boots up, apps should open.
Also, try to delete just one of the apps. Then go back in and redownload it, and it should let you successfully download and install all of your apps.
Okay I will give it a go again and see! This is really bugging me and will let you guys know.
