These are instructions on how to downgrade your iPhone's Baseband using KiPhone. This software is a patched version of ZiPhone released by kIREmk. It has not been found to cause the issues some have experienced with ZiPhone.
To follow this tutorial you must have 1.1.4 firmware installed on your iPhone. If you accidentally downgraded to 2.0 then use this tutorial to downgrade to 1.1.4.
Step One Download KiPhone from here to your desktop: Mac, Windows
Step Two Double click the downloaded zip file to extract its contents.
Step Three Double click the extracted file (ZiPhoneOSX patched by kIREmK 04.05.04_G [En]) to launch the application.
Step Four Once the application has launched make sure the BL 3.9 & 4.6 tab is selected. Also make sure the Baseband downgrading checkbox is selected.
Connect your iPhone to the computer and click the Start button. ZiPhone will put your iPhone into recovery mode and you will be informed that the process will take 2 mins and 30 seconds.
Windows: If you are a windows user then simply check off Downgrade Baseband and Debug Boot and click the Start button.
Step Five Once the process is complete you will be informed that it completed successfully. You now have downgraded your Baseband to 04.04.05_G!

I wish to express some arpieciatpon to the writer for rescuing me from such a instance. After looking through the search engines and meeting views which were not helpful, I believed my life was over. Existing without the solutions to the difficulties you've sorted out as a result of your good posting is a serious case, and those that might have negatively affected my entire career if I had not discovered your web page. Your personal competence and kindness in playing with every part was invaluable. I am not sure what I would've done if I hadn't come upon such a stuff like this. I can at this point look ahead to my future. Thanks so much for the reliable and sensible help. I will not think twice to suggest the blog to anybody who should receive guidelines about this matter.
I have observed that over the csruoe of creating a relationship with real estate entrepreneurs, you'll be able to get them to understand that, in every single real estate deal, a commission rate is paid. In the end, FSBO sellers tend not to save the payment. Rather, they try to win the commission simply by doing a strong agent's job. In completing this task, they commit their money and time to complete, as best they could, the assignments of an realtor. Those assignments include exposing the home by marketing, offering the home to willing buyers, making a sense of buyer desperation in order to make prompt an offer, arranging home inspections, taking on qualification investigations with the mortgage lender, supervising maintenance tasks, and facilitating the closing.
Hi There !
I have update the version 3.0 Os ( newest iphone os ) but that bring me a problem with baseband , so i want to ask how can i downgrade 04.05.04_g to 02.30 ??
please answer me , Bye.
Hey guys, please clarify me this...this tool allows you to downgrade 2g firmwares or 3g also? Because y tried everything on my 3G iphone and it gets stuck in "Entering Recovery Mode"...i already tried and got bricked...only thing was to restore the custom ipsw but still with the 2.2.1 baseband...i got into the iphone.forums.de site but i can't read german :-(
if your iphone is tuned into an ipod touch, if u have no signals and itunes is rejecting your phone and if any of unlocking programmes like iliberty is not helping, u will ind your peace with this little zip file.
no matter how u did it, if ur baseband is changed to 04.05.04_g and u want to downgrade it, this works and this is the simplest way that works also. after u download the file, rght click on it and click on extract to****filename****. than click on the 'ziphone patched by kiremik' file with orange logo.
if u tray to run the ile in winzip without extracting, it will not work properly.
well , same F problem, i just follow this tutorial but when im tryin to open the ZiPhoneOSX patched by kIREmK 04.05.04_G [En] it crashes and the stupid system tell me the application quits, its F 2.44 in the morning and im tired of this problem , is there any other place to download this patch or what can i do, i need my F phone back!!!!

I just want to thank the people who posted this thread with the file. I am from Manila, Philippines and i'm just one of those silly guys excited to upgrade my 2G iphone to version 2.0 and wala.. i got BRICKED. I've tried everything.. unlocking jailbraking and activating my iphone with every software i know.. but yes.. the IPOD features works but it has NO SIGNAL, therefore no SMS or Calls were sent in and out of my phone. I'm desperate of finding solutions in the internet, almost gave up.. until i've found this! IT"S BACK TO NORMAL AGAIN! THANK YOUUUU>> SALAMAT PO!
I'm running an iPhone 1.1.4 which was downgraded from a iPhone 2.0.
Since the baseband didn't get downgraded in the process, I used KIPhone to downgrade my baseband from 04.05.04_G to 04.04.05_G. It did downgrade, but downgraded all the way to 04.03.13_G??
Any idea why or how? From here what is the best way to upgrade to 04.04.05_G?
Thanks.
