    Default [BootLoader] How can I go from 3.9FakeBlank to 4.6BL original ?

    Hello I am planning to downgrade to 3.9FBl but I want, to Have the option to upgrade back to 4.6 original. I searched the forum but I couldn't find any tutorial of commands so that I can upgrade back to original bootloader. Can anyone help me to upgrade? Thank you very much

    Ps. I have downloaded the original bootlader . Its filename is " BL-46-ORG.bin ".

    I'm interested in the same thing as well. Basically it's only thing keeping me from restoring to 1.1.4 and then use the iPlus utility.

    Anyone ?

    why would first reflash BL to 3.9fakeblank and then flash it to 4.6fakeblank?
    It's dangerous enough to do it once

    I want flash back to the original bootloader in case I have to return it to apple. I do not want to flash it to 4.6FBl and return the phone. I also wanto to downgrade to 3.9FBL so that I can upgrade and unlock to 1.1.4

    Yeap, I'd like to have the option to return my iphone to apple as well in case something goes wrong. I want to have the ability going from 3.9FBL straight to 4.6Original BL without any problems

    Let's start to collect information..
    this is what i know.
    To go back to original 4.6 we will need 4 files..
    1- original 4.6 nor
    2- testcode.bb
    3- iunew
    4- latest secpack


    then we will need to run iunew and you are on 4.6bl
    I did not try it. We need some guru to comment it.
    And process is similar with Geohot HW downgrade form his blog...

    Solor, who created iphone-tools might now the procedure. As far as I know iunew is an executable command of the iphone(i am not quite sure though). Why do we need the secpack though??

    i have read here that apple take only back your phone if you a a LEGIT at&t customer...
    <<<--- if you find this post usefull, give me a good reputation by clicking on the THUMP up symbol

    1.1.2 OTB
    Restore to 1.1.4
    BL 3.9FB
    BB 4.04

    If you know what you do an you like commandLine use iPhone-Tools from SoLaR
    If you dont know what you do use iPlus
    If you want to f**k up your Phone use ZiPhone

    Nope if you restore your iphone and virginize your baseband , apple will replace your phone. If you read the warranty it doesn't say anywhere that you have to have an A&t contract
