Earlier today we told you that Dev Team releases Ultrasn0w 1.2 Unlock for iOS 4.2.1 it turned out that in order to unlock iOS 4.2.1 you need to update your baseband with iPad baseband. if you are stuck on Baseband 05.14.02 or 05.15.04 you can update your baseband to 06.15.00 with pwnage tool or redsn0w and enjoy the Ultrasn0w unlock.

Following is a step by step guide to update your baseband to 06.15.00 with pwnage tool. Pwnage tool is available for Mac OS only, if you are looking for a Windows solution then check our Guide to Update Baseband 06.15.00 With Redsn0w

Tethered vs Untethered

  • iPhone 3G are untethered up to iOS 4.2.1

    WTF?

    This device isn’t eligible for the requested build

    Hey Vinay how about addressing this issue…

    Also why when the file “iPhone2,1_4.2.1_8C148a_Restore.ipsw”
    is downloaded from your own link does pwnage say it cannot find the firmware?

    i tried this method and got to point when im restoring custom IPSW with itunes. Getting error 1015 and getting stuck on recovery mode.. What can i do on this?

  8. Sam Davidson December 4, 2010 Reply

    Currently i have valid AT&T service however moving overseas so paying term fee on 3gs Version4.2.1(IC148a) with broadband 5.15.04. As i update via PWNAGE when it asks if i have “authorized through itunes” do i say yes or no? Next 30 days in the states but moving first of january to China. I’ve tried few times and it worked once (i think) however when verifying with “apple” it rejected the package i had built through PWNAGE. Suggestions?

    Hey I got through the whole process until the final step and it says this iphone could not be restore. This device isn’t eligible for the requested build. any ideas?

    Hi, I have a locked iphone 3GS with 4.1 intalled.
    Followed the whole procedure to create a custom firmware on 4.1.
    When restoring to this customfirmware itunes notifies: this device isn’t eligible for the requested build.
    On the other hand, if i try to create a custom firmware on 4.2.1, pwnagetool does not want to accept this ipsw.
    I do not care if i have 4.1. or 4.2.1, I just want my iphone unlocked.
    thanx

    Hello, I recently purchased a 3g Iphone, and it came with 3.1.3 FW and 6.15.00 Baseband. I cannot unlock it, id does have cydia but it wont even let me install ultrasnow. In the middle of the install process, the iphone freezes and shuts down, then when I try to reboot, it is stuck in the apple logo.

    What can I do?

    Thanks

    I have 4.1 3GS new bootrom and followed the directions, however, I get the error “Device is not eligible for requested build”??? Looks like Apple is making everyone upgrade to 4.2.1?? However, the tool will not let me use the 4.2.1 bundle….please help

    I have an Iphone 3gs and when i followed all of the steps in itunes it said this iphone is not “compatible”. What does this mean? how can i fix it because i use t-mobile and i need an unlock. i havent used this as a regular Phone in two months. everything worked fine until itunes popped up. When i tried doing 4.2.1 on Pwnage tool it didnt accept it and now i am without a jailbreak and unlock. If you have answers reply to this message

    Asad, I had the same problem. Everything seemed like it was working until the reboot and then I checked my baseband and it did not upgrade. Remained at 5.14.02 =(

  17. Asad November 30, 2010 Reply

    Like you said 4.2.1 , when i browse 4.2.1 pwnage tool rejects it saying wrong firmware bundle. but it does take 4.1 firmware. I would say the directions are not clear on this page. I used the 4.1 bundle and i am still unable to upgrade my baseband. I was able to create custom firmware based on 4.1 and 3.2.2 ipad but that restore did not upgrade my baseband.

    Hey there!
    I did this method to my Iphone 3G and it worked successfully! However, I also tried this same procedure with my Iphone 3GS 4.1 5.14.02, and it didn’t work..Cydia however did appear, But the ultrasn0w source addition didnt work, and the baseband also remained the same at 5.14.02, I did download the Ipad stuff and it worked successfully with my Iphone 3G..

    any tips?

    My software is 4.1, 5.14.02
    I upgraded to 4.2.1, 5.14.02..and still same results..

    Hi Vinay,

    i am with a 3GS 4.1 Baseband 5.14 newbootroom.My question is:Can i just upgrade the Baseband to 6.15.00 with Redsnow without updating the firmware to 4.2.1 in ordre to unlock with Ultraswon.Or should absolutley update my firmware to 4.2.1 via Itune before using Redswon.I sorry i’ve been searching for an answer and have not been succesfull.

    Thank you very much for your reply

    Unlocking phones is silly. Go Android!

    On Step Seven:
    You will be asked to enter your administrator password. Do this then click the OK button.

    For what the password is required? The tool must read and write IPSWs – and for this the tool has all rights. It smells.
