    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

    I am in /var root# and it tells me when I type "chmod 755 BBUpdaterExtreme" I get an error saying chmod cannot access 'BBUpdaterExtreme' no such file or directory.

    Not sure how to fix, if anyone can tell me where I made my mistake I would appreciate it
    hey i had the same problem.

    before you do number 3, try cd /var/root
    and try 3,4,5
    it worked for me.

    I run the BBUpdaterExtreme per http://www.modmyi.com/forums/general...ml#post3877511 and after it runs through everything at the end it says:
    !!! Exception at :0:
    - BBUReturnError(1)/2:Unsupported memory class CodeClass for EEP transfer. Are you sure ICE2_02.28.00.eep is an EEP file?
    Re-enabling sleep....OK


    I rebooted and I'm still at 2.30 baseband. According to "Tom" at On the iPhone: 5.8 Exploit I'm screwed. He said "When you get the .eep error: Are you sure this is an eep file? Or something similar, that means your bootloader cannot be exploited, i.e. you're screwed for now."

    I don't get why I can't do this if I have the 5.08 bootloader? Anyone have any insight on that?


    Just saw that someone else at that same site had success with the same version of the bootloader that I have....

    It worked with my 3g iphone boot loader ICE2_BOOT_05.08_G2M3S2
    firmware 2.2.1 baseband 02.30.

    Thank you George, and thank you Tom for your post, it helped me very much.

    Good luck




    Doesn't make me very happy! LOL
    In case anyone cares I used method 2 that involves using the bspatcher and it worked.

    Went from 02.30.03 to 02.28.00
    Thanks


    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


    ****Remember "Don't eat yellowsn0w!****



    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

    Good Luck and thank Everyone who made this possible
    Sorry I will Go back and Press the Thanks Button tattoojack

    Thanks

    NICE, it actually worked. But the only good that this will do is allow those who currently cannot use their phones because they unknowingly upgraded the firmware right? I mean doing this won't prevent you from having to do it again with 3.0 comes out right?

    so if your with a carrier already, this is completely useless? if not how so(curious)?

    darn.. i have 5.9

    /private/var/root and /var/root are two different places...copy files into var/root and try again.

    method:2 worked like a charm for me
    I downgraded the baseband, installed yellowsn0w and unlocked my 3G phone previously jailbroken with 2.2.1 firmware
    btw /var/root and /private/var/root are the same folders
    /var is a symbolic link to /private
    Thanks to him121213 and tattoo jack

    Found this site on the internet...... thought it was cool to read about this topic and MMI

    Downgrade your iPhone 3G baseband from 2.30 to 2.28!

  22. #120
    I have read that there are 3 bootloaders depending on when your phone was made. Can you just clarify, does this mean (at the moment) its a fixed value that does not get changed with firmware updates etc i.e. if you 5.09 you have always had and always will (at the mo) have 5.09
