    Default What if Ultrasn0w doesn't work?

    I have tried every iPhone version with every different baseband and Ultrasnow will not unlock my carrier. I have also tried Blacksnow but also unsuccessful.

    So, my question is....am I completely screwed now? If Ultrasnow won't unlock my phone with any OS on any baseband, does that mean my phone is now an iPod? Do I throw it away?

    Does the DevTeam look at the instances where the unlock doesn't work, or do they just continue forward with iPhone 4 now?

    iPhone 3G Model A12421
    OS: 4.0.1
    Baseband: 05.13.01
    Bootloader: 5.08
    Carrier: Telstra NextG SIM

    Default What if Ultrasn0w doesn't work?

    Okay, for anyone that is interested, I managed to get my phone back online. After hours and hours of searching online and trying every possible combination I could think of, I managed to restore carrier unlock and my phone is again usable. Thank god because I was starting to think I was screwed forever! Obviously, Ultrasn0w 0.93 didn't work for me, which is weird because Ultrasn0w (or Yellowsn0w back then) has unlocked my phone in the past.

    Anyway, I upgraded my 3G iPhone to OS4.0 and jailbroke it with Redsn0w 0.9.5 which then allowed me to install Fuzzyband through Cydia. I downgraded my baseband to 4.26.08 and then downgraded my OS to 3.0. I had to then use iRecovery to complete the downgrade (just google it if you need more info) and then jailbroke it with Redsn0w 0.7.2. I then downloaded UltraSn0w_Unlock_0.6_by_Rizwan.rar (again google it if you need as I can't remember the exact site I downloaded it from). I connected my phone and ran the Unlock3G_3.0.bat file. I rebooted my phone and...oh my god....I had SERVICE!

    I made a call to another mobile and was sucessful. I then turned my phone off and back on because I wanted to make sure it would continue to work if my phone ever went flat. It came up with 'No Service' so I ran the batch file and rebooted again. Bingo! Full Service - even after many restarts.

    So there you have it. Obviously the latest version of Ultrasn0w (0.93) has some major changes in it that my phone just doesn't like. So for all you people out there that have a 3G iPhone and have updated to OS4.0 and can't get service, this is something to try. It definately worked for me and I'm just stoked that my phone is back working. I think my phone will stay on 3.0 for a VERY long time now. Stuff updating.....it's NOT worth the stress!

    Good luck!

    You are very lucky to be able to use fuzzyband.
    There have been a few reports that some newer ultrasn0w versions don't work for some people. However the vast majority of users have had no problems.

    It would be great if you gave some feeback on what network(s) you tried to use ultrasn0w with and which ultrasn0w versions did or did not work.

    Also.. it is possible to use baseband 04.26.08 with newer iOS versions than 3.0 - you need to use pwnagetool to prevent baseband upgrades - or use fuzzyband to downgrade baseband again. You might find that iOS 3.1.3 and baseband 04.26.08 with ultrasn0w might be a good combination.

    I think I'm pretty lucky indeed to be able to get my phone working again. I was at the point where I didn't think anything would work.....this was pretty much my last hope.

    My phone was originally on OS3.1 with Baseband 5.11.07 (before I decided to upgrade to OS4.0) and was working well on the Telstra Next G network. I think (not 100% sure) that I unlocked my carrier with Yellowsn0w back then.

    However, after moving to OS4.0, I couldn't get Ultrasn0w to work. I was only able to install Ultrasn0w 0.93 because I couldn't find any reference to any other repo's in Cydia that hosted older versions. I ended up trying Ultrasn0w 0.93 with OS4.0, OS4.0.1, OS3.0, OS3.1.2 and OS3.1.3. I also tried baseband 4.26.08, 5.11.07 and 5.13.04. After all that failed, I then tried Blacksn0w with OS3.1.2 and OS3.1.3 but again nothing.

    As a last resort, I downgraded my baseband to 4.26.08 and went back to OS3.0 as I found a reference to Ultrasn0w 0.6 within the Unlock3G_3.0.bat patch but it was only for OS3.0. After running the batch file twice, I finally got (and maintained) carrier unlock.

    I had tried all of the above with both a Telstra Next G SIM and Optus SIM. They were the only two SIMs I had access to.

    As for moving to OS3.1.3 and trying Ultrasn0w 0.93 again....I'm thinking I won't risk it. I don't believe the latest version of Ultrasn0w likes my model iPhone for some reason. In saying this though....I do have access to another phone (same model, same specs). I might play around with that and see if the results come out the same.

    Sounds like a weird one.

    Never heard of any problems with Aussie networks and ultrasn0w.

    Sometimes these problems can be resolved by getting a replacement SIM from your carrier - however Telstra NextG SIMs are not very old.

    I also have a relatively ancient Optus SIM (I know it's not really ancient because it can hold more contacts on the SIM than the very early SIMs) that works fine in my 3GS. I don't need to use ultrasn0w though.

    Digging around in old posts here I found a location for ultrasn0w 0.9.2 (the version that should support ultrasn0w on all iOS 3.x versions with your baseband)

    http://www.hackint0sh.org/f159/76588-7.htm#post472395

    That bundle also includes mobile substrate (which is updated a lot more often than ultrasn0w). This bundle is intended for pwnagetool.
