    Smile [Tutorial] How to testpoint downgrade bootloader and unlock OTB 1.1.2

    For those who don't want to wait on a software downgrade, i have written a tutorial on how to downgrade the bootloader using testpoints. This method is basicly the same as the first unlock geohot published.

    Tutorial here: http://iphone.unlock.no/bootloader_downgrade.htm

    Thanks to geohot (and the people he thanks): http://iphonejtag.blogspot.com/


    Update at 30th Jan: 1.1.1 baseband firmware files are now included (thanks drh!), so instead of restoring your phone at the end, you can just write tha baseband manually and unlock with anysim, and you have an unlocked 1.1.1 phone. The tutorial is updated with this info - please give feedback on that last part in this thread!



    Read this if you don't have WiFi:
    I have made the files available for offline usage as well:

    Bootloader Downgrader PXL
    PXL package is untested - does it install ok in iBrickr? The files inside are OK, just not sure installation in ibrickr works. Files should be installed to /usr/bin/bbtools/

    Bootloader Downgrader ZIP
    This is the exact same file downloaded when installing Bootloader Downgrade package in Installer.

    Usage:
    (do this first in all cases)
    Code:
    cd /usr/bin/bbtools/
    launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
    Then:
    To flash baseband after you complete iunew (testpoint downgrade):
    Code:
    ieraser
    bbupdater -f 111.fls -e 111.eep
    bbupdater -v



    Unlock.no's faster and better way to jailbreak 1.1.1 phones!
    Today i studied how jailbreakme.com jailbreaks the phone etc, and i noticed that jailbreakme.com copies a 736KB archive with the needed files, but also LOTS OF CRAP (sourcecode, hidden mac files etc). So i decided to tweak the solution a little.

    • I have removed all the crap jailbreakeme.com serves, so my archive is only 136KB, but still have ALL relevant files. This will make it much faster and more stable, since the file transfer is reduced 600KB.
    • Latest version of Installer (b10) is installed, and also latest version of Community Sources (modmyifone repository)
    • http://i.unlock.no/ is addded as a (trusted) source in Installer.


    To jailbreak using this method, instead of adding URL jailbreakme.com, you add url: i.unlock.no (http:// not necessary) to the contact you create after dialing *#307# etc. Have your phone docked to the computer when visiting the jailbreak page.


    Note: Jailbreaking using this method will add i.unlock.no as a trusted source. If you don't trust this Installer source, don't do this.

    Note2: I did not develope this solution myself. I use jailbreakme.com's solution, and just tweaked it. All credits/donations goes to everyone who worked on this solution: http://jailbreakme.com

    Tutorial is currently untested, but as mentioned, it's the same as the first unlock method so it should work.

    Seems quite simple IMO.

    My only question is...

    I assume after you SSH into the phone, you're not turning it off when you proceed to opening it?

    I mean common sense says so, if you say "Don't restart" I just don't see how that's possible with the phone open.. Which is why I'm a tad bit confused.

    It honestly looks like a simple procedure. But I can see where failure to pay attention to detail would cause problems for some people.
