hallo
mit den beiden anleitungen wird es nicht funktionieren da man die 2.28.0eep patchen muß. ich habe gestern eine anleitung mit downloadpacket gefunden womit man sein iphone downgraden kann und es funktioniert:winkiss: habs getestet . ich werde die anleitung im laufe des tages übersetzen und hier posten mit den downloads:winkiss:
hier die englische anleitung:
Download BBUpdaterExtreme here:
http://rapidshare.com/files/198571862/iP...seband.zip
Download BSPatch Here:
http://gbatemp.net/index.php?download=1741
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. C:\patcher). 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 C:\patcher
"C:\patcher" 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!
viel erfolg
