Thread: Can an iPhone 3GS iOS4.1 05.14.02 BL6.4 be downgraded to 4.0 and unlocked?

    Question Can an iPhone 3GS iOS4.1 05.14.02 BL6.4 be downgraded to 4.0 and unlocked?
    Hi, I just got a 3GS running iOS 4.1 and I didn't want to upgrade the baseband to iPad's baseband so I was wondering if it can be downgraded to iOS4.0 and than I would be able to use UltraSnow again, no, it doesn't have saved SHSH blobs
    I really appreciate if someone could tell me yes or no.
    Thanks

    Model: iPhone 3GS 16GB
    Serial #: 86004B6******
    Baseband: 05.14.02
    Bootloader: 6.4
    Model: MB715

    Only iPhone 3G can downgrade basebands and that is only if the bootloader is 5.8. You have a 3GS and your baseband is not unlockable, therefore your only option is to upgrade to the iPad baseband if you want to unlock.

    Thanks buddy, I'll just go with the IPad baseband, hope I will loose just the GPS and not the battery life.
    Would you recommend me any newer iOS version in particular to install with the IPad baseband?
    What's the best one for the 3GS/iPad-baseband at the moment?

    I think the battery issue can be fixed if it occurs. Currently you're at 4.1, which is fine, if you are asking for what I'd prefer a 3GS to be on I would probably say 4.2.1 or 4.3.3. However to upgrade to either of those you'll need SHSHs saved, do you know if you have 4.2.1 or 4.3.3 SHSHs saved?

    Thanks bud, I have just saved the SHSH using iFaith-v1.1, that means that now I have SHSH 4.1 backed up for my phone in case I want to revert it in the future if possible, right?

    Right, saving your 4.1 SHSHs now with iFaith allows you to restore to 4.1 now whenever you need to. The thing I was asking though is if you have already saved 4.2.1 and/or 4.3.3 before Apple stopped signing it. If you wanted to upgrade to 4.2.1 or 4.3.3 you would need those SHSHs to have been saved prior. But if you want to stay on 4.1 that's fine too, nothing wrong with that

    Sorry but I didn't understand it, I got the phone from eBay and it had 4.1, that's all I know, how do I save a 4.2.1 or 4.3.3 like you said? Could you please point me to the right direction?
    Thank you

    You can't save it anymore, you can only save 4.1 and 4.3.4 which looks like you've got 4.1 down. The only way for you to have SHSHs for 4.2.1 or 4.3.3 is if the previous owner saved the SHSHs. You can check with TinyUmbrella by clicking on "Save SHSHs" and view the log.

    Ok so it's either 4.1 or 4.3.4, should I be aware of anything when going for 4.3.4?
    Can I follow the guides on the internet for 4.3.3 when installing 4.3.4 and it will unlock with UltraSn0w normally?
    Lastly, I ran tiny umbrella several times and it keeps complaining about not being able to start the TS server, kill process ID (4).
    Thank you very much

    Just adding, I checked ipswDownloader and it says "Tethered jailbreak", I have no clue what does that mean, is it bad?

    You don't want to check for any SHSHs first before trying anything? Just ignore the TSS Server popup for now, that's nothing to worry about. You should check for any SHSHs for 4.2.1+ first before I try to guide you through doing anything.

    Sounds like your jailbreak right now is tethered. Just a guess. It can be changed to untethered once I figure out what it is you have available in terms of SHSHs.

    Yeah it looks like you only have 4.1 saved at this point. So what you would end up doing is upgrading your baseband but stay on 4.1. I'm going to suggest a restore to 4.1 using your SHSHs because I'm assuming you have a tethered jailbreak. Unless you can test something for me, turn the phone off and turn it back on. Does it allow you to access your springboard or does it get stuck?

  13. #13
    I have full access to the springboard, there's even Cydia installed on it, I downloaded and played Quake a minute ago.
    Are you saying that I will be stuck on 4.1 forever now?
    Thank you

    Since you have your 4.1 shsh blobs this is the only fw you can restore to other then the newest 4.3.4 fw which is what apple is currently signing.

    You will need to install the ipad baseband if you are requiring an unlock

    Edit: what i.Annie said

  15. #15
    Thanks, Annie and iHappy, for the valuable advise. I would like to go to the latest FW if possible since I will have to install the iPad baseband anyways, I just would like to know if it will matter or not installing 4.1 or 4.3.4 in terms of jailbreak and unlock, if not I would go with the latest.
    Cheers.

    4.3.4 is not recommended since the jailbreak for it is tethered and not 100% fully functional.
    Plus ultrasn0w doesn't support 4.3.4. Stick with 4.1

  17. #17
    Excellent, that's all I need to know for now, I will search for a guide on 4.1 and when 4.3.4 becomes "100%" I'll update since I have nothing else to loose with the iPad baseband.

    Thanks iAnnie, iHappy, I appreciate your help.
    Regards

    Last question, based on my serial number my 3GS week is 04? Howcome? RedSn0w wants to know if it is an old or new 3GS.

    Ok looks like you are not tethered. All you have to do right now, is get Redsn0w and install the ipad baseband. There will not be any need to restore or rejb or anything. So that's all you have to do, update the baseband with Redsn0w and then go to Cydia and unlock with Ultrasn0w.

    Redsn0w asks because of the old boot new boot thing but that's not really a concern. If it's an old boot just go ahead and select old bootrom in redsn0w and continue on with it. It shouldn't matter bc all you're doing is installing the iPad baseband and doing nothing else with redsn0w.
