Update 2: Latest is Installous 3.1.10. This already includes all the programs I listed below including AppSync so you don’t have to install them separately. Make sure you’re on iPhone OS 3.0 and up. You may get some error messages during the installation of Installous but just ignore. If you have problems installing an app, try setting the Native Installation “ON” or “OFF” and install again.
Update: Try the new Installous 2.0.3 in Cydia before performing the fix below. I tried it and works great.
Many have reported problems downloading cracked apps from Installous after jailbreaking to iPhone 3.0 firmware–such as “unable to find executable”, “Script failed. Unable to decompress”, previously working apps no longer work, white icons, deleted apps, etc.
To fix these problems, you need to do the following:
In Cydia, upgrade all essential files when prompted.
Re-install the following files in Cydia (use the search function and if not found, add the Source first):
- Cydia Installer (Source: http://apt.saurik.com)
- Erica Utilities (Source: http://apt.modmyi.com)
- UUID Generator
- Darwin CC Tools
- Installous (Source: http://cydia.hackulo.us)
If you haven’t already installed an app on your iPhone from the Apple App Store (a free app will do), install one now.
Open Installous and Download an app. Install only after downloading. Check to make sure the app is working.
To sync cracked apps to iTunes, install AppSync for OS 3.0 from Cydia. Reboot.
Note: If after syncing to iTunes, your apps failed to transfer to your iPhone, unselect all applications in iTunes and sync. Then select all applications and sync again.
