Updating jailbroken ipod
This process is only possible using a downgrade, which can be a fairly difficult operation to complete (Apple authenticates all new software installs using their own servers).
SHSH blobs are in the process of being phased out in favour of the tougher-to-beat APTicket.
For the purpose of this guide, I will use as an example upgrading from 2.0.2 to 2.1. First off, if you have never jailbroken, you don’t need to worry about this guide. The complications come when you have a jailbroken device and you want to upgrade.
Just hook your i Phone up to your computer and tap the “upgrade” button and wait. Say you are running 2.0.2 and have a lot of Cydia apps installed.
If you’re not making warranty claims, you still might want to hold off creating a backup.
Jailbroken i OS firmware can run riot accessing different parts of the filesystem usually only reserved for apps and system components.
The moved files become inaccessible but stay on your disk which means you essentially just lose the space. Here are the steps that you should take on a 2.0 device to upgrade without any loss or issues: Sync with i Tunes. It may take you a while on 2.0 – 2.0.2 but you need this step. At this point, if you are a contract subscriber (AT&T or such) you need to activate your device in i Tunes.Do this instead: There are a lot of tales online – mainly anecdotal, which comes with the territory when it comes to jailbreaking – that creating a backup of a jailbroken device is a bad idea.There are a few reasons for this, one of which is that if you’re making a warranty claim it’s possible for Apple to tell that your device was jailbroken once some evidence of the jailbreak has been copied back to the freshly restored phone.If you upgrade, you will find your hidden icons are still hidden but the apps required to unhide them are not yet installed.
Here are some steps to help: First off, you never use “upgrade” on a jailbroken device.
Important: For this reason, you shouldn’t upgrade the software on your phone or restoring to stock if you depend on your jailbreak for an unlock.
