Si vous avez une erreur 16xx, mettez votre iPhone en mode DFU et recommencez. Vous pouvez également essayer un autre port USB, d'enlever votre carte SIM ou redémarrer votre ordinateur. Si la restauration échoue encore, essayez un autre ordinateur !

Dixième étape
Maintenant vous pouvez utiliser votre methode favorite pour sortir du mode Restauration l'iPhone et le débloquer.

Ci-dessous vous trouverez des instructions pour vous aider, cependant, nous vous suggerrons d'utiliser PwnageTool car il se chargera de downgrader le baseband.

Windows: iLiberty+, WinPwn
Mac: iLiberty+, PwnageTool

La première fois j'ai essayer d'ouvrir iLiberty+ avec iTunes de lancer. Cela a eu pour effet de sortir l'iPhone du mode restauration et de fermer l'application. Je l'ai ré-ouverte et j'ai pu débloquer mon iPhone du premier coup.

PwnageTool va downgrade votre baseband. Il n'y a aucune raison d'utiliser un autre outil cependant si vous êtes obligé... Ici, se trouve les instructions pour downgrader votre baseband avec KiPhone.

Onzième étape
Cliquez sur Software Update à partir du menu Apple dans le coin supérieur gauche de votre écran.
Comment Downgrader Votre Iphone en Version 2.0 vers la Version 1.1.4

I only want to suggest a thing. Before Pass No. Six, I had to reinstall Apple Mobile Device, thats Quicktime. You did not cmment anythig about it in the tutorial and without that program the computer is not able to detect your Iphone. Thanks. :)

Hey, sure! the risks are very simple: buakcp all your data before attempting to jailbreak, in the very rare event that everything doesnt go according to plan, you can restore your iphone/ipad through itunes and it will be as if you havent done anything! now if you decide to go through with it, just download absinthe 0.4 for windows/mac/linux, according to your os and follow the onscreen instructions.Let me know what happens
