    I've been waiting for this day for a long time. I realized having iOS 4 actually sucks due to much disadvantages and It's time for an upgrade.

    With no experience in actually jailbreaking an iDevice (I bought it jailbroken), I have taught myself in 1½ years, most things about jailbreaking and all about tweaks, themes, apps, repo's etc. As time flew by, many newer iOS version came around which have soon limited iOS 4 users a lot by making tweaks and apps for iOS 5 onwards only. Due to this, who wouldn't want to upgrade?

    Alright, I have an Jailbroken and Unlocked 4.3.2 iPhone 3GS running a NEW Bootrom - Baseband: 05.16.02
    As iOS 6 has problems with some Cydia tweaks, I thought I'll upgrade to iOS 5.1.1 (if it's possible :rolleyes:)

    I wanted to be sure I'm taking a right route, so I don't mess anything up
    So if you guys could help me a lil' bit, I would really appreciate it :)

    Thanks!

    Download the latest version of iFaith (v1.5.6) and run it. Plug in your iPhone 3GS and click "show available shsh caches on server". If it shows you have 5.1.1 shsh blobs, save them and it'll check if they're valid which it should

    From there, you can stitch your shsh blobs to the 5.1.1 ipsw firmware package.

    Do you rely on a software unlock? Or any kind of unlock for that matter

    5.1.1 is on the available blobs list. It has verified successfully and I have installed it ^.^

    Oh and can you clarify your last question :3 Do you mean a sim carrier unlock, if so, It's already done on the phone I believe.

    So you have installed and are successfully using 5.1.1 right now?

    My last question was referring to whether you have an official unlock. If you are successfully using 5.1.1 right now, you don't need to heed my last question

    LOL No, I think you have misunderstood. I have installed the 5.1.1 blob from that iFaith or something. I have no clue where to actually start this XD

    I'm not even satisfied whether I have everything backed up! I just need to have everything set up and I know what I'm doing before I begin the actual upgrading.

    Oh, you should've said downloaded the shsh blob :p

    Running iFaith, click build signed ipsw with blobs. Browse for the 5.1.1 blob. If you already downloaded the ipsw, click browse for an ipsw.

    It'll verify the ipsw and then you click build ipsw. It'll start building it.

    It'll then say it has finished creating the custom signed ipsw. You'll need to put your device into pwned DFU mode to restore to the custom firmware. Then if you continue, it'll tell you steps on how to enter the pwned DFU state

    You could wait for another person to verify this is the correct way before you do it though

    Well I haven't downloaded any IPSW's in advanced, so I clicked "Download it for me" button instead of Browse for one. It should be the correct one I guess if it's downloading for me. However, if I should download an alternate, please send me a link.
    Here are some good sites for most iOS firmware's for all iDevices:
    http://www.coolestguyplanettech.com/ios-ipsw-firmware-download-links-5-0-1-5-1-5-1-1/
    http://www.felixbruns.de/iPod/firmware/

    (EDIT: It's downloaded (686 MB) and it's finished building the IPSW! Thanks :D)

    Now, do I need to use redsn0w or something, or iTunes to restore the custom IPSW? Also, would this preserve my baseband? Now I don't want to loose my sim carrier unlock.

    P.S. On the sidenote, I'll use OpenBackup to backup my repo's/tweaks/packages etc. Is this a good choice? I don't think that PkgBackup works for me.

    you could click download it for me and it should download the right one for you. i personally would download the ipsw myself just because i like to know for sure if it's correct and such. 686MB should be the size of the 5.1.1 ipsw for the iphone 3GS

    you need to put it into pwned dfu mode in order to restore the custom firmware. if you open ifaith, you should see "use dfu pwner (ireb)". once it is in pwned dfu mode, you can shift + click restore that custom package via itunes.

    i'm not certain if it preserves your baseband or not. if you don't rely on ultrasn0w for your unlock, you'll be fine whether you update your baseband or not. if you DO rely on ultrasn0w for unlock, i wouldn't do this update yet until someone chimes in. earlier, you said you got an official unlock from your carrier, right?

    do you have it with AT&T?

    edit: i know for sure sn0wbreeze never updates the baseband though so you can use that to create your custom firmware instead?

    I have no idea how the device was SIM unlocked and who the original carrier was, which doesn't help at all. However, as the baseband is not supported by ultrasn0w right now, but it's unlocked, it could have been a carrier unlock. If not, should I still preserve it? I wouldn't have to re-unlock unlock it, right? *sigh* To be honest, I don't have a clue. If there is no other way keeping the unlock, I'll just update it without preserving my baseband and have my phone without a sim :/
    Also, I live in the UK and I'm currently using 3 carrier SIM - no AT&T.

    EDIT: I forgot to ask, if this does go on ahead, is this method a untethered jailbreak?

    I'm really unsure about the unlocking business. Does your phone currently have ultrasn0w installed? If the phone was officially unlocked by the carrier, you don't have to worry about unlocking it again. If your phone works fine and doesn't have ultrasn0w installed, then it shouldn't matter if you update your baseband or not since it doesn't seem to rely on a software unlock

    Yes, iOS 5.1.1 is an untethered jailbreak. After you update to 5.1.1, you can use absinthe to jailbreak

    Cool Beans. I've checked, ultrasn0w isn't installed on this.

    Alright, what I have to do:
    • Backup my stuff with OpenBackup
    • Enter pwned DFU Mode with iFaith
    • Restore custom 5.1.1 IPSW on iTunes [Shift click]
    • Jailbreak with Absinthe
    • Restore my backup from OpenBackup and re-install apps/games

    I'd personally recommend restoring your cydia tweaks manually. You should make an iTunes backup though

    Thanks darrick!
    If I have to re-download all my tweaks and stuff, I think its best to use AptBackup. I have also downloaded OpenBackup to use as well, you know, double backup. However, I would have used PkgBackup, but I'm too cheap :p

    I have also actually written all my packages too. I might just consider the traditional method.
    Screenshot's off SpringBoard also taken.
    Contacts, Notes, SMS files copied to PC.
    Code:
     Located at:
    /private/var/mobile/Library 
    I think I'm just about done. A few last checks won't hurt ;)
    I'll return if I'm stuck, arise a problem, or once I'm finished :D

    That's weird.

    iFaith tells me I have failed to enter DFU Mode, however, iTunes says it is in Recovery Mode. My screen is black.

    What's going on??

    EDIT:
    I checked on the sinfuliphone forum, and some guy was having this problem. Another guy told his solution:

    URL: http://www.sinfuliphone.com/showpost.php?p=716527&postcount=131
    If this solution doesn't work, I'll be bummed :/

    EDIT2: It's done and now restoring :D

    Done

    I can now refer to this :D :p

    Yes, I have finally finished with an "unlocked" jailbroken iPhone 3GS running 5.1.1 WOOP!

    Thanks darrick for all your help. Just a quick note, I did receive a message saying your storage is almost full. However, I checked iTunes and Cydia and it seems alright.
    Anyway, thanks again :)

    EDIT: For some odd reason, I installed AptBackup again and tapped the restore button. Now just before it finished, a message poped up stating storage is almost full :?
    Now it resprang and I was suprised that AptBackup did work almost. Most packages were restored, I have to add the repo's and the rest of the packages back manually. I checked the storage and it's normal.
    Is this a glitch or something?

    Honestly, I'm not sure. Manually installing your tweaks is always better than an automated process. It may take longer but at least you have full control and actually know what's happening

    Glad you have your iPhone up and running :D
