iOS 8.4.1 Jailbreak – Everything You Need to Know
Apple released iOS 8.4.1 patching several exploits that were used to jailbreak iOS 8.4 - iOS 8.1.3. This means you would no longer be able to jailbreak iOS 8.4.1 using TaiG jailbreak tool. With iOS 9 release almost here, following are all the iOS 8.4.1 jailbreak details and precautionary steps that you need to know about to safely stay on a jailbroken device.
iOS 8.4.1 jailbreak: what to do right now
The first and a very obvious step is to stay away from updating your iPhone, iPad or iPod touch to the latest iOS 8.4.1 update as it would stop you from jailbreaking your devices until TaiG discovers some new exploits. In the meantime, you should update your device to iOS 8.4 if you haven't done so yet. Apple will stop signing iOS 8.4 possibly next week giving you enough time to manually install it on your device and jailbreak it.
If you have already updated your device to iOS 8.4.1 then you can downgrade it to iOS 8.4 as Apple is still signing the OS version. Go to our comprehensive guide to manually install iOS 8.4 on your iPhone, iPad or iPod touch. To keep up with the signing status, go to ipsw.me. When the status sign goes red it means you'd no longer be able to downgrade to or install iOS 8.4 on your devices.
If you need to restore...
Next are the possible chances when you might get into trouble due to some problematic tweak that pushes you to restore your iOS device. Install SemiRestore (and OpenSSH) on your jailbroken device as it allows you to restore your device to stock condition without losing the jailbreak. This will be a very useful tool for the times when due to any kind of issues you need to restore your device. SemiRestore also removes all the jailbreak tweaks during the process which helps in getting rid of the buggy tweaks. Jailbreak status is safe, device gets to near stock condition and buggy tweaks are gone. What more can one ask for?
OpenSSH installation is a requirement because SemiRestore needs it to be installed on a device. Install OpenSSH from Cydia and you will be good to go. SemiRestore is compatible with all the jailbroken devices running iOS 8.4 - iOS 5.
Buggy tweaks and why to stay away from them
Since we are talking about the problematic tweaks that often lead to reboot loop making you to restore your jailbreak devices, here is one life-saving (err, jailbreak-saving?) tip. DO NOT INSTALL EVERY OTHER TWEAK THAT COMES YOUR WAY! Please do not. Be very careful when installing jailbreak tweaks as a buggy tweak would leave you with no choice but to restore your device leading you to possibly lose the jailbreak. Try to stick with the trusted names and sources and always be cautious while swimming in the unknown waters of the jailbreaking world.
While you should be super careful when installing tweaks from unknown / unreliable sources, it is equally important to get rid of the jailbreak tweaks that you no longer use. Uninstall all the jailbreak tweaks that you don't use anymore as it reduces the chances of tweaks having compatibility issues with each other.
Also, do not play with the file system using tools like iFile as you might end up deleting some system files leading you again to the restore process. Enjoy your jailbroken devices but do not go overboard either with the tweaks or with the super access that it offers to you and you'll be all good.
TL;DR: Don't install iOS 8.4.1 until TaiG updates us. Install SemiRestore for safe-restore process. Do not play with the filesystem. Stay away from buggy tweaks and uninstall any jailbreak tweaks that you don't use.
Note: You might want to use tools like TinyUmbrella to save SHSH blobs helping you to create IPSW files while they are still being signed on. SHSH blobs help you restore your device to a version that Apple is no longer signing. While rendered irrelevant by Apple, developer claims that it would be relevant again thanks to an exploit discovered by iH8sn0w.
