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.

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 site but i can't read german :-(

can i downgrade baseband 2.30.03 to 2.28.00. im on orange uk using 16GB iphone 3g!
ai - February 15, 2009 at 12:26am
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.

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!
contactmypics - August 4, 2008 at 8:10pm
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.

Doesn't work mang... it's sitting on "Entering Recovery Mode" for last 15mins... oh well
kIREmK - July 21, 2008 at 11:32am
Hi, i have seen it yet that iClarified release a "How to" of my little toy.... @ Zibri: i don't want to make it my own tool, i wanted that the people can see that is YOUR tool that i have patched :D Sry if i had insulted you ... that wasn't my idea to do this.... KiPhone (patched ZiPhone) isn't working perfect i know.... but for 80 % of the peope how downloaded it, it works good. And by the way .... iDemocrazy3 is the same script how it ZiPhone 3.0 it is .... sry for my bad english...
Troy - July 20, 2008 at 1:37am
I'm using the windows version and get to the GUI. I check off downgrade baseband and debug boot. When I click START the GUI disappears and nothing happens. Is anyone else experiencing this ? I really need my baseband restored badly. Thanks
Hausi - July 17, 2008 at 2:37am
Thanks so much - after hours of trial and error: it works! The funny thing is, that KiPhone crashed always - so i tried it on my desktop, iMac, and so it worked.
waylor - July 16, 2008 at 2:47pm
oh my good it works i tried with bootneuter and everything and it doesn't worked but with this it works yeah thanxxxx....!!!
N41 - July 16, 2008 at 2:26pm
Alright, lets fix all of this.. a. Yes you cant be on 7.7, downgrade to 7.5 or 7.6 b. Richard Burns, if youre phone goes into recovery and nothing happens we suggest you do another restore to 1.1.4 and try again c. The purpose of this tutorial is for those that accidentally upgraded to 2.0 but dont have an ATT sim to unlock or jailbreak d. Genna, uninstall everything and delete it from trash. Make sure your itunes is 7.5 or 7.6 Also, if you have a MAC, pwnagetool 1.1 downgrades the baseband for you. You just need to re-pawn and re-create a new ipsw N41
waylor - July 16, 2008 at 2:07pm
oh my good it works i tried with bootneuter and everything and it doesn't worked but with this it works yeah thanxxxx....!!!

Hi the iTune 7.7 keep on popping up on my mac... Do I need to uninstall the iTune back to version 7.5 or just leave it? Thanks

Richard Burns - July 16, 2008 at 7:39am
iClarified help! I upgraded to 2.0, i followed your instruction, but when my phone goes into recovery mode nothing happens
LadiHood - July 16, 2008 at 1:51am
OMG!!!!! I wanna cry... 5days w/o a phone and FINALLY a solution!!! KUDOSSSSS!!!!!!! ;-D
Gustavo - July 15, 2008 at 8:38pm
Still cannot understand the purpose of that. Someone said that it is for those who miss upgraded to 2.0, but the tutorial says you have to be on 1.1.4.
rob - July 15, 2008 at 5:22pm
too bad zibri that this one works and your downgrade feature doesnt, ziphone 3.0 couldnt come close to cracking my baseband, you should be so pleased
Genna - July 15, 2008 at 12:55pm
After I download kiphone I keep getting the message "The application ziphoneOSX quit unexpectedly." Any ideas? Please help. Do I need to completely remove it off my computer and do it again? Does that entail throwing it in the trash or is there more to it?
Number_41 - July 15, 2008 at 12:40pm
No but i dont mind taking all the credit. N41
iClarified - July 15, 2008 at 12:01pm
@Zibri, if that is really you... Please note that iClarified did not release this modified tool. We are simply instructing people on how to use it. The modification was done by kIREmK at
iClarified - July 15, 2008 at 10:07am
You may need to downgrade your Baseband if you have updated to the 2.0 software and you wish to return to 1.1.4!
miguel - July 15, 2008 at 9:50am
hi, it might sound silly, but why would i need to downgrade my baseband? Thanks if you can let me/us know. ps. i am on 1.1.4 iPhone 1st gen, 04.04.05_G miguel
N41 - July 15, 2008 at 9:08am

I want to show some appreciation to this reitwr just for rescuing me from this condition. As a result of searching through the the net and meeting ideas that were not powerful, I was thinking my life was done. Being alive without the presence of approaches to the problems you've sorted out by means of your blog post is a serious case, and the kind that would have in a negative way damaged my entire career if I had not come across your blog post. Your own training and kindness in touching all the stuff was precious. I'm not sure what I would've done if I had not come upon such a solution like this. It's possible to at this point look forward to my future. Thanks for your time so much for this professional and results-oriented help. I won't be reluctant to propose your web page to any person who should receive tips about this matter.

Le inconve9nient est donc que cmeipuseoent de fils (et au sein de eux les policiers) e9liminer en bloc ce entraeenement qui peut bien entendu que laisser non toutefois de accuser des connaissance brutal et xe9nophobe de9shonorant la re9publique, mais meamement et plus infiniment de impliquer dans quoi rue sans issue nous ont habituer les manoeuvrier se9curitaires qui se affermir sans rele2che de8s le introduction des anne9es 1990, et plus mais depuis les insoumission de 2005. Retenir donc inde9niablement que nos enseignant se montrer de force e0 d’entendre un commission un minimum composite et de refaire la part des choses. Dans un ne9cessaire temps, nous nous accumuler sur la subvention chemin de fer et inde9niable de ce denier au discussion sur l'organisation de la rousse domestique en france. Dans un sous-verge temps, nous bavarder palpable de ses explication homme de guerre qui nous avoir l'air plus fragiles.

What's wrong zibri? Dont like the fact that someone took your work and modified it? hahahaha N41
Zibri - July 15, 2008 at 6:41am
How lame. I have nothing against patching and modding. But geez, you also used the same interface and patched the donate button. That's really LAME ! You could just ADD your name to it. Or contact me to add it. c'mon! You could do better than that.
Jano - July 15, 2008 at 4:15am
Thanks for the patched app!!! It worked perfect, really thanks. I updated just to see if this worked and it does.
myk - October 19, 2009 at 10:48am
I'm trying to restore my baseband. When I execute downgrade using the app, I'm getting the error below. USBMuxListenerCreate: Unknown error: 0 Thanks in advance
