Welcome to the iPadForums guide to upgrading your 6.x iPad jailbreak!
From time to time you may be faced with the opportunity to upgrade from one jailbreakable version of IOS to the next. For example, this guide could be used to upgrade a jailbroken iPad on IOS 6.1 to 6.1.2, maintaing all of the Apple and Cydia apps, tweaks, and settings on the way. This guide will only support you upgrading to a version of IOS which Apple is currently signing. At the time of writing, there is no known way to get around Apples security regardless of what SHSH Blobs you may have saved, so only the "current" version of IOS can be upgraded to. This guide also assumes that the "latest" version of IOS can be jailbroken. If it can't, then you are pretty much stuck where you are... Sorry
If you happen to be trying to upgrade from an older version of IOS, such as 5.0.1 or 5.1.1, then this guide is still valid for you, however you need to be more careful around how you approach backing up and restoring your Cydia tweaks and settings. Compatibility between major versions of IOS and tweaks from Cydia is a complex web, and just because you have things running fine on 5.x, does not necessarily mean they will work at all well on 6.x. The best advice for upgrading an older jailbreak is to use the "manual" mentod of backing up your jailbreak. i.e, write down all the teaks you have installed and re-install them manually again once you have a 6.x jailbroken device
PreparationNote: You should never try to use the iTunes "Update" option or Over The Air (OTA) update feature on a jailbroken device. This will simply fail and likely render your device temporarily inoperable until you perform a full restore using iTunes.
Download the latest version of the evasi0n tool for your desktop PC OS from the official site here - http://evasi0n.com/. You will need to jailbreak the device during the process.
Optionally, you can also download the latest firmware directly to your PC to make the upgrade process easier and more reliable. Download the latest version of IOS from our handy thread here - Official Apple IOS Firmware Download Links for iPad
The basic upgrade process is relatively simple...
- Backup your iPad using either iTunes or iCloud.
- Optionally backup your jailbreak apps, tweaks and settings.
- Restore the device to the latest version of IOS using iTunes on the PC.
- Restore your backup taken in step 1.
- Jailbreak the device.
- Restore your jailbreak backup taken in step 2.
The rest of the guide provides a little more information on each step...
Let's Upgrade the Jailbreak!
- Backup! Whenever you are going to make a significant change to your device you should always perform a backup first
It does not matter whether you use iTunes or iCloud to backup your device, although using iTunes on your PC (even as a one off for this process), is usually faster than relying on the cloud.
If you use iCloud, go to Settings > iCloud > Storage & Backup > Back Up Now.
If you are using iTunes, connect your iPad to the PC, open iTunes, select your device, and on the Summary tab press "Back Up Now".
- Backup the Jailbreak! This is an optional step, and how / if you choose to backup your jailbreak data will depend on the complexity of the JB setup you have on your device. You have 2 basic choices...
i) don't bother backing up any aspect of the jailbreak and start again, installing all your tweaks and apps from Cydia once you have completed the upgrade. In this case, you might find it useful to write down all the tweaks you have installed, or take some screenshots to remind you of the setup
ii) use a jailbreak backup application such as PkgBackup or xBackup. These provide comprehensive options for backing up all of your tweaks, apps, settings, and often additional things such as themes, icon layouts etc. See our guide on PkgBackup for more info here - HOW TO - Use PKGBackup to safeguard your Jailbreak Apps & Settings
- Restore the device to the latest firmware in iTunes. Connect your iPad to the PC, start iTunes, and select your device. If you downloaded the firmware file to your desktop, as recommended in the preparation section, you should hold down the Shift key (Windows) or Alt key (OSX) whilst clicking the "restore" button on the Summary tab. This will allow you to select the firmware file and avoid the lengthy, and sometimes troublesome, iTunes download process. If you don't have the firmware file to hand, simply click the "Restore" button and let iTunes do the work. If you do happen to run into an error related to the file not being downloaded properly, consider downloading it manually as suggested at the start of this guide.
iTunes will take around 10 minutes to fully restore the device to a clean, factory fresh state. Remember, you can only restore the current / latest version of IOS using this method. You cannot restore any previous version of IOS 6.x.
- Restore your Backup! When the restore operation completes, allow your iPad to reboot whilst still connected to your PC. iTunes should prompt you with 2 options. Either setup the device as new, or restore from a previous backup. IF you chose to use iTunes to make your backup in Step 1, then you should choose to restore the device from that backup. Allow the restoration of your backup and a full sync with iTunes to complete.
If you chose to use iCloud, now is the time to disconnect the device from the PC. You must then complete the Setup Wizard on the device, and when prompted for your details make sure you follow the flow which results in you restoring your iCloud backup in full. You only get this option whilst initially setting up the device. If you make a mistake, you will need to reset the device from the Settings menu in order to activate the option again (note you should never normally do this if you are a jailbreaker - only in this one special case!).
If you do use iCloud, but have a large number of apps etc. to restore from backup, you can connect the iPad to the PC and sync it once the initial restoration of your backup is completed. Otherwise, all your apps will be re-installed by downloading them from Apple again, which depending on your network connection, could take a very long time!
- Jailbreak! Once all of your stock apps, settings, media, etc are restored back onto the device, it's time to jailbreak it again. Shut down iTunes, start the evasi0n tool, and follow the instructions. Don't forget our guide here if you need a refresher - TUTORIAL - Jailbreak the iPad with IOS 6.0 to 6.1 using evasi0n
If all goes well, you should now have a jailbroken device with a clean install of Cydia on it.
- Restore the Jailbreak! Depending on how you approached Step 2, it's now time to restore your jailbreak to its former glory. If you chose the manual method, then you know what to do. Simply go into Cydia (allowing it to initialise first time as normal) and then install your tweaks / apps until you are happy.
If you used one of the Jailbreak backup tools, use Cydia to install the tool first. Then start the tool (e.g. PkgBackup) and configure it appropriately so that your backup can be restored.
Congratulations - If everything went to plan, you are now the proud owner of an upgraded Jailbroken Device!
