    Are you using the same method used back when people were stuck in 3.1.2 boot loop without SHSH and had to preserve baseband while going to 3.1.3 (ie removing the LLB image)?

    Was just wondering if that method still worked for 4.1. Could be very useful until a updated pwnage tool is released with the new exploit.

    Hi,
    I'm definitely interested. I have an iPhone 3GS with the newbroom and iOS 4.0.2 that I want to jailbreak but it has been impossible because it is really new and the SHSH are not on Cydia. Please let me know

    Hi guys. I follow the procedure, and I'm stuck with an apple logo after "kick it out of recovery" with TinyUmbrella.
    Any ideas? Do I need to do anything else?
    Thanks

    Gave error 10 after verifying. I tried the old way and got the same results. It used to get error 6 with the method of 3.1.2 - 3.1.3. It did get error 10 before the baseband update so still safe there, but nothing will kick it out of recovery. Even tried running limera1n.

    If you have SHSH, restore to a previous firmware. If not you will have to wait for OP to come up with something else (though he seems like he has disappeared) or wait for an updated pwnage tool that uses the new exploit.

    It is a brand new iPhone 3GS with iOS 4.0.2. so using Tiny Umbrella... I could only save the SHSH for iOS 4.1, nothing before that. I tried to reinstall 4.0.2 and it keeps giving me errors... it says that the phone is not allowed to install the firmware... or something along that lines...

    So you will have to wait for an updated pwnage tool too if you want to be able to unlock.

    Default Not sure if it works
    I tried it but not sure if it works.

    But do need help.
    I have a 3gs with new bootrom, I assume since I got the phone in July. I was previously JB n Unlocked on 4.0 and saved SHSH.

    Problem: I upgraded to 4.1 and JB but can not unlock it. Reading all the threads, I think I know the answer but have to ask. Can 4.1 be unlocked with baseband 5.14.03?
    Can I restore to SHSH that was saved to 4.01 and will that get me back to 5.13.02? if so, how?
