Thread: From 3.1.3 with SHSH to 4.x new bootrom?

  1. #1
    Question From 3.1.3 with SHSH to 4.x new bootrom?
    Like the title explains, is it possible yet?
    I got a perfectly normal iPhone 3GS new bootrom on 3.1.3 jailbreaked&unlocked with spirit.
    Is it, or when will it be possible to jailbreak at unlock 4.x?

    Thanks in advance!

    use the newest redsn0w beta, google a custom 4.1 ipsw created with pwnagetool or create one with sn0wbreeze and use redsn0w to restore to that to preserve your baseband and unlock with ultrasn0w when done, here is a link for the newest redsn0w beta

    I've got a 3GS firmware activated, which I uploaded, PM me your email address and confirm it's 3GS, activated firmware for 4.1 you want and I'll send you it.

    As j3st3r said, you then just use latest redsnow option to put you phone into DFU mode before doing the shift+restore to the downloaded firmware.

    Unlock with ultrasnow, job done.

    Redsn0w asks for my CURRENT .ipsw, but i don't have it, what is my options?
    If i jailbroke with spirit, then it should be the official 3.1.3 right
    Because that was what it ran on before i jailbroke? (Tell me if im wrong)
    BTW, is the jailbreak tethered, or does have any issues?

    You will have to download the official 4.1 when running Resn0w 0.9.6b2 to put you into DFU mode, once you are at DFU mode, Do the Shift + Restore to your Custom Firmware of 4.1 created by Pwnage tools 4.1.2

    If you have the compass icon, then it is a 3GS

    So just to get this clear..

    1 I'll have to download the 4.1 official.
    2 Use it WITH redsn0w to go to DFU mode (what about when it asks for the current?)
    3 Then do the normal shift + restore way in iTunes with the 3GS 4.1 firmware i got from "westonben"

    (i AM sure it's 3GS, cpu clock is running default for 3GS, so no doubt )

    Yes, when you run Redsn0w, you will have to browse to stock 4.1 in order to get you to dfu. You can practise running redsn0w first without hooking it up your iphone. Remember when you do the shift + Restore to Custom firmware, not a stock 4.1.

    Yeah you can have your phone disconnected when you run redsn0w after you select "just enter pwned DFU mode right now"..Then plug phone in & follow the steps to put in DFU...
