Thread: Downgrading from 4.0.2 to 4.0.1
10-16-2010, 07:10 AM #1Downgrading from 4.0.2 to 4.0.1
Hello my fellow iPhone users.
I am very new to all of this, and I would much appreciate your help.
I have the 4.0.2 software and would like to downgrade to 4.0.1 as I want to jailbreak my phone.
Is it recommend to do so and could it effect my iPhones performance? And will it effect my iphone, if I want to upgrading iPhone software in the future?
More importantly what is the easiest and safest way to do so?
Please help me out.
I understand if this is a repetitive question but I could not find an answer in any of the forums.
Thanks in advance

None of you need to downgrade to jailbreak. Just jailbreak where you are with limera1n.We're all just toymakers in the game of life.

limera1n jailbreaks 4.02 so there should be no need to downgrade.

Hey guys. Sorry for the late reply.
So all i have to do is download Limeera1n and that should jailbreak my phone?
The only way I know how to jailbreak is by going onto the website jailbreakme and then 'soide to jailbreak' but it does not work and there is a message which states my phone software is to new and I can't do so.
Once again I am very new to all this so If someone can tell me exactly what to do, step by step, it would be great!

But what is DFU mode and will it negatively effect my iphone preformance?
and what is lemera1n?
i thought to jailbreak the phone you have to go onto the website 'jailbreame' and then through that just download cydia.

will it do the same thing as jailbreakme does?
and also jailbreakme is more popular so should i not wait till it is able to jailbreak version 4.0.2?
10-22-2010, 02:29 PM #20
Jailbreakme will only jailbreak at 4.0 and 4.0.1.
Limera1n will hactivate and jailbreak 4.0.2 .
Remember , you cannot apply jailbreak onto an already jailbroken iphone. You need a restore first before you apply this jailbreak.
