Once you have JailBroken your iPhone 4S and iPad 2 using Absinthe, it would open up the application and redirect you to greenpois0n.com, the website of Chronic DevTeam which is responsible for running the code for the further progress. At this time, you may encounter ‘error establishing database connection’ error in mobile safari. If it happens, just follow the following steps and you are done.
1) Go to Settings>VPN>Turn it ON.
2) It should be performed only if Absinthe says that it is done or it will not work on your Mac.
3) As soon as you would toggle VPN, it would throw you an error. The device would crash and reboot in a while.
4) If something similar to it doesn’t happen, you need to re-run Absinthe on your Mac.
5) If you face any other strange problem, the device should be restored from the iTunes. We are hoping that you had taken the backup before. So it could be easily pushed into the device once again.
6) Apple still allow you to restore to iOS 5.0.1 even if you don’t have SHSH Blobs saved for the respective device. You shouldn’t worry until you care about software unlock.
I hope that this has solved all your problems while JailBreaking your iPhone 4S and iPad 2. For further doubts, shout out in the comment section.
