  • Downgrade 3G Baseband from 2.30 to 2.28

    For those who have wanted to unlock their iPhone 3G but have updated to the 2.30 baseband, hope is now here. Thanks to the work of dev pH, a tool has been created to downgrade your baseband, and allow a unlock to occur once again.

    only works for baseband 2.30 and bootloader 5.8

    (im sorry if the original post didnt clarify enough because doerrfan decided to reword things when he moved it )

    to check your bootloader version, visit:
    Baseband Commands - The iPhone Wiki

    (run at+xgendata in minicom)

    To run the pHaseBanDowngrader, connect via SSH to your iPhone and copy the downloaded folder (phasebandowngrader) into the folder "/Applications" on your iPhone.
    Note: The folder MUST named phasebandowngrader with lowercase letters!

    To run it, open MobileTerminal and type "login". The user is "root" and password is "alpine" by default. Then type: "cd / Applications/phasebandowngrader/", then, to run the downgrader, type "./phasebandowngrader"
    METHOD 2 (found by tattoo Jack)
    For other people who still needs a full instruction, here is an update to Tom's instruction.

    Download BBUpdaterExtreme here:
    RapidShare: Easy Filehosting

    Download BSPatch Here:
    GBAtemp.net :: Downloads :: ROM patchers & header info :: bspatch

    Here's where you'll need some command prompt skills. Extract the BSPatch program and iPhone_3G_02.28.00_baseband.zip and all related files into a folder you can remember (ex. Catcher). Also, place the ICE2_02.28.00.fls and downgrade.patch in the same folder (downgrade.patch is from Master geohot above found here: http://lpahome.com/geohot/downgrade.patch)

    Open your command prompt by hitting start, then run, and type in "cmd" without the quotes and hit enter. In the command prompt, you'll need to type

    cd Catcher

    "Catcher" is the example directory but you can replace it with wherever you've placed the BSPatch and ICE2_02.28.00.fls files in.

    Now type in:

    bspatch ICE2_02.28.00.fls patchedbaseband.fls downgrade.patch

    In the example folder, there will now be a new file called patchedbaseband.fls, which is pretty self explanatory.

    Copy that file back to your desktop or a folder that you can easily find and also copy ICE2_02.28.00.eep and BBUpdaterExtreme into the same place.

    Rename patchedbaseband.fls to ICE2_02.28.00.fls.

    Now that you have your patched baseband, your BBUpdaterExtreme and the .eep file in one place, you're ready to move them onto your phone.

    You'll need to know how to SSH into your iPhone, and I'm not going to go into detail about that, but you should be able to find that information easily.

    (you can also use DiskAid or Iphone Browser to upload the files instead of SSH)

    Copy the three files *ICE2_02.28.00.fls* - the new one that is patched
    ICE2_02.28.00.eep
    and
    BBUpdaterExtreme into /var/root
    (make sure you're not in private/var/root).

    Now, you'll need to find download and install Mobile Terminal, which can be found in Cydia or Installer, or I guess the new Icy.

    After you've gotten Mobile Terminal installed, open it up and follow these instructions carefully (capitalization counts!) to check what version of bootloader you have.

    (All case sensitive and you may need to use cd .. to change to the right directory you've uploaded the files to)

    1. Type in: su
    2. Type in the password: alpine
    3. Type in: chmod 755 BBUpdaterExtreme
    4. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    5. Type in: ./BBUpdaterExtreme queryversion

    Look for "Boot Loader Version:" in the output.

    Mine said "5.09" which I can only imagine means 5.9 so I did not have the availability to downgrade.

    Here you can stop if you're like me, and don't have the option to downgrade. You can restart your phone (because the phone is now not working since the CommCenter process has stopped running) to restore it to normal, or alternatively you can type in

    launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist

    But you may be in luck and have 5.8, in which case, continue on to the downgrade.

    Close Mobile terminal, re-open it, and type in the following commands.


    (All case sensitive and you may need to use cd .. to change to the right directory you've uploaded the files to)

    1. Type in: su
    2. Type in the password: alpine
    3. Type in: chmod 755 BBUpdaterExtreme
    4. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    5. Type in: ./BBUpdaterExtreme update -f ICE2_02.28.00.fls -e ICE2_02.28.00.eep
    6. Reboot your iPhone

    Check under Settings-General to see your (hopefully) downgraded baseband!
    simplified version of method 2 (Koolman0)
    For those of you that are still having problems This Should be more simple
    .................................................. .................................................. .........
    Download:
    1. Make a folder on your desktop
    2. Extract All to the same folder (All Three Files)
    3. In the Folder there should be a Shortcut file called "Prompt" open it
    4. Now type in:
      bspatch ICE2_02.28.00.fls patchedbaseband.fls downgrade.patch
    5. Now Make a New Folder in that Directory Call it "new"
    6. Three Files need to be copied To the "new" folder
      • patchedbaseband.fls
      • ICE2_02.28.00.eep
      • BBUpdaterExtreme
    7. Rename patchedbaseband.fls to ICE2_02.28.00.fls
    8. SSH into your iPhone
    9. Copy the Three files (patchedbaseband.fls, ICE2_02.28.00.eep, BBUpdaterExtreme) to /private/var/root
    10. Now go to MobileTerminal (on your iphone, This app can be Downloaded from Cydia or installer)
    11. Type in the Following Commands *****Case Matters*****
      1. Type in: su
      2. Type in the password: alpine
      3. Type in: cd /var/root
      4. Type in: chmod 755 BBUpdaterExtreme
      5. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
      6. Type in: ./BBUpdaterExtreme queryversion
    12. NOTE:
      • if you see a 5.8 continue
      • if you see a 5.9 STOP this will not work for you Sorry
    13. Continue if 5.8
      1. Type in: su
      2. Type in the password: alpine
      3. Type in: cd /var/root
      4. Type in: chmod 755 BBUpdaterExtreme
      5. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
      6. Type in: Type in: ./BBUpdaterExtreme update -f ICE2_02.28.00.fls -e ICE2_02.28.00.eep
      7. Reboot Device
    14. Once the iPhone has restarted go to Settings> General> About> At the bottom should say 02.28.00 (then you jump up and down in JOY)
    15. Last But not Least Unlock
    P.S.
    Here are the three Files you will be creating
    so just copy these to you iphone (continue from Step 8 or 9)
    Three Files inside this RAR
    this tool has been tested by multiple people and WILL NOT brick your device. if you have bootloader version 5.9 it will not work. you can try but it will not work (still no risk of brick)

    use at your own risk, but there is really no risk of doing any damage to your device unless you do something absurd

      Why is there so much hostility here?

      him, I am basing my info off a conversation with mn, ls, cd, and a few others. None of them will say anything for certain and are extremely tight lipped about it. You know, you are in that crowd too, you have to probe for answers and decrypt the answers that you do get. LMAO I know there has been progress with 2.30 but your right all focus has been on the newer baseband. I don't have or am trying to give anyone yell0wfever as they are calling it but I want people to know that the situation is handled. From what I understand the new baseband is exploitable. I know they have busted their tails on it and I suspect you will see the new unlock announcement a couple weeks following the release of the new iphone.

      Don't get so wound up! Life's not worth it. The odd capital letter helps but if it's such a biggie for you, don't worry about it.

      If only we could all be like MN!
      I have never heard him be anything other than humble and courteous
      , he never states anything as 'fact', just what he believes. His only fault is, as all us true nerds know, is that he has muscles, which obviously is totally unacceptable

      I know nothing. So when the dev team say
      The commenters on this blog that have high ratings (20 or above) understand this intimately so please listen to them when they try to assist those waiting for any unlock
      you really shouldn't listen to them.

      him121213 is so much more rliable.

      if i was on that blog more i would probably have that rank but instead i am actually behind the scenes working on real things that you and everyone else use everyday. if you decided to do something useful instead of helping people who dont trust themselves enough to read directions you might understand some of this stuff and have an inside ear, but i dont see that. i am just wasting my time coming back here. im sorry but i wont be checking back to see the smart ***** comment you left to make yourself feel better

      Why are you getting bent out of shape? I didn't say I had mn on record with a confromation. You sir are not on the dev team and neither am I. How many times have me and you been burned by our convos on irc? I was just saying that I have heard some things. I have some transcripts you might find interesting. We are suppose to be on the same team, so lets act like it. I need your help finishing all those projects we have going on. So drop me a line when you can

      DId anybody say you had to put it after every word? No. After every sentence, like I'm doing. It makes the readability of your posts easier to read, if, of course, you don't want me to read your posts, then so be it. Be monjy.
