Thread: Downrgade 3GS from 4.1 to 3.2

  1. #41
    Ahhh Hacktivation issue. Do you have an AT&T simcard that you can use to activate the phone? Once activated, you can then JB and install ultrasn0w.

    If this is not possible, then your only choice is to downgrade to version 3.1.2 and below coz that's the lowest firmware that can be hacktivated such as by blackra1n.

    If you are using a 3G, you should be able to downgrade but you will not be able to unlock since your baseband has been upgraded.

    I think your iphone is with official carrier, restore to snowbreeze without activating it.
    You can try this, just restore to official 4.1 and no jailbreak, you should have signal and if you want to jailbreak, use Redsn0w 0.9.6b1 (Mac only) to jailbreak at 4.1, then you will be jailbroken and still get signal.

    As for your girlfriend, her phone is not from the official carrier, she can only jailbreak but N0 unlock.

    Yeah, yeow is right. Telekomsel is the official iPhone provider in Indonesia so if you're setting up sn0wbreeze, you should set-it up without activation (as the phone will look for Telekomsel simcard to activate automaticallly).

    I am a bit surprised though coz I would have thought that Indonesia would be selling Factory Unlocked iPhone just like Malaysia/Singapore.

    so, if im not mistaken taking these conclusion, would be just go to the TELKOMSEL and ask them to provide the simcard and my iphone would be activated n ready to use? same as well to my gf iphone?
    thanks 4 all ur advises.
    cheers

    The question then is, Did you buy the iPhone from Telekomsel? If you did, then yeah ... just go to TelekomSel and request a SimCard and you should be able to activate the iPhone.

    What SimCard are you using now?

    i didnt bro :-p

    first i bought both unlock iphone 3g jailbreak inside (ex AT&T), but we did wrong by updating auto via itune 10, and now we cant use both the iphone.

    when i start using the snowbreez, i bought a new simcard (TELKOMSEL-WITHOUT BUNDLING THE IPHONE PACKAGE, ONLY A COMMON TELKOMSEL SIMCARD, WITHOUT ANY ACTIVATION, SINCE IPHONE IS SELLING BY BUNDLING WITH TELKOMSEL PROVIDER IN INDONESIA) and trying to activated via snowbreeze. but my gF using other carrier, 3 INDONESIA. after successfully snowbreezing, my iphone may detect the carrier (TELKOMSEL) but no signal, and my gf may not detect the carrier (3 indonesia)

    Lord saputra .... if it was AT&T before and you have upgraded to 4.1, then you're out of luck. The baseband has been upgraded and there is currently no unlock at the moment (ultrasn0w will not work with the new baseband).

    You need to wait for the unlock (which is probably going to be a long time as mentioned by the dev team).

    hi, i have a 3gs with old bootrom and yesterday upgraded from 3.1.3 jailbroken with spirit (blobs saved on my HDD from before i jailbroke), to 4.1 which i tried jailbreaking with ultrasnow but failed. so my question is can i go back down to 3.1.3 and just use spirit again?

  23. #56
    Jailbreak with ultrasnow? Ultrasnow is for unlocking.

    What are you jailbroken with at 4.1? Are you even jailbroken? What's your baseband (modem firmware)?

    If you upgraded to standard 4.1 firmware from apple then you can downgrade and rejailbreak but you aren't going to be able to unlock it again until a new unlock comes out (and apparently no one is even working on it at present so it could be quite a wait).

    snowbreeze sorry. and im not jailbroken on 4.1, i created my custom IOS with snowbreeze and then tried restoring my phone to it but kept getting error 1600 (think it was this) so im just on standard 4.1 atm. how can i find out my modem firmware?
    im not bothered about unlocking it, just wanna jailbreak.

    ive just tried doing this:
    4. Add a line at the bottom of the host file with this information
    127.0.0.1 gs.apple.com

    and its saying i cant save it :S even though im admin on the comp

  25. #58
    OK, I can talk you through it, but before we start, can you go to settings>general>about and confirm the "Version" (which is your current firmware) and your "Modem Firmware" (which is your baseband)

  26. #59
    version is 4.1 (8B117)
    modem firmware 05.14.02

  27. #60
    Yes, that confirms you are on stock 4.1

    Download tiny umbrella from here:

    The Firmware Umbrella

    Now, plug in your phone and start tiny umbrella. Go to advanced options and select 3GS 3.1.2 from the drop down. Hit Save my SHSH (from Cydia) and see what it says. Now move on to 3.1.3, 4.0, 4.0.1 and 4.0.2 to see which ones you've got.

    Depending on which ones you've got, and which firmware you want to be on we should be able to do just about anything since an unlock is not important.
