Loading ...I am sure quite a few of us would have accidentally upgraded their unlocked iPhones to 2.0 firmware. Here is what you can do.
I found this on Hackint0sh.org’s forum:
- You MUST have an earlier version of iTunes than 7.7 to do this – I used version 7.6.2 (the one before 7.7).
- Put the iPhone i DFU mode and restore to 1.1.4.
iTunes say error 1015 of course as iTunes can’t downgrade the baseband. - iBrickr couldn’t kick iPhone out of restore mode, so I restored to firmware 1.1.4 one more time, THIS time with regular restore mode. Once again error 1015 in iTunes.
- NOW iBrickr was able to kick iPhone out of restore mode.
- Then I used “ZiPhoneGUI – patched by kIREmK” to downgrade the baseband.
- Restored (regular restore this time) to 1.1.4 again (using iTunes 7.6.2).
- Used iBrickr to kick iPhone out of restore mode.
- Then using PwnageTool 1.1 to put my own custom firmware 1.1.4 on the iPhone.
- WORKING….

Update – 20th July 2008: iPhone users who had upgraded 1.1.4 to 2.0, can now breathe free. Go to Unlock ANY iPhone link now and download PwnageTool-2.0 to jailbreak 2.0 firmware.

This one is from the BigBoss. I am sure this would definitely help us all:
- The first problem in your downgrade is that you probably are getting error 20 in restore mode and error 160x in DFU mode. This is due to iTunes 7.7. So, you now you need to uninstall iTunes 7.7 and install iTunes 7.5. Make sure after your iTunes 7.7 uninstall you reboot your pc as it requests you to. **OSX users, see note at bottom of page to downgrade your iTunes.
- Now that you have iTunes 7.5, you will still have the DFU driver for 7.7. This is good and will allow the process to work. Put your phone into DFU mode using the DFU steps.
- Restore using iTunes 7.5. You will get an error like 1011, 1013, 1015. This is normal and expected. An error 1601, 1602, 1600 or anything else is not ok.
- Once you get error above, leave iTunes open and kick your phone out of restore mode. I recommend just loading winpwn(PC) or pwnage(MAC) and pwning the device at this point. If pwnage fails to work, you need to restore your phone again. You should be able to use normal restore mode, however. Other ways to kick out of restore mode may be ibrickr, jailbreak 1.1.2 (boot phone), iLiberty+.
- Once completed, you have a pwned device with baseband 4.05.04_G from firmware v2.0.
- To get back to 04.04.05_G (1.1.4 baseband) load bootneuter. If you don’t have this, install it from installer. Run bootneuter with Neuter, 4.6, and unlock. When it’s done, you will have an unlocked 04.04.05_G right back where you started.
Note: if you get a boot neuter error like 05, 02 or such, you probably have more steps. Unfortunately, there is no safe answer to this one.The only method I know of to do this is to use a patched version of Ziphone as described here. Before you do this, you should know the risks. Read my Ziphone warning here. Your other option is to just wait for dev teams pwnage v2.0.
Note for OSX users:
If you are on OSX and want to attempt to downgrade your iTunes, you can try these steps:Load up Terminal and type the following:
killall iTunesHelper
sudo -s
rm -r /Applications/iTunes.app
rm -r /Library/Receipts/iTunesX.pkg
rm ~/Library/Preferences/com.apple.iTunes*
rm -r /Applications/iTunes.app
rm -r /Library/Receipts/iTunesX.pkg
rm ~/Library/Preferences/com.apple.iTunes*
rm -r /System/Library/PrivateFrameworks/MobileDevice.framework[via - Sleepers.net]
Update:
Some of you have reported “I am in DFU mode and keep getting error 20 from iTunes restore”. Answer, you are not in DFU mode. Follow the guide and the DFU link. An iPhone in DFU mode has no image on the screen and looks powered down.
Some of you are reporting error 160x (1600, 1601, 1602, 1604 etc) on the iTunes downgrade while in DFU mode. I suggest trying another PC. You may still have some residual files left over from the 7.7 install. Make sure you are in iTunes 7.5 with drivers from 7.7.

i’m doing wht verb wit said but my 7.5 itunes tells me that my iphone can’t be used and wants me to download the new 7.7
how do i connect my iphone to itunes 7.5?
If you have upgraded your 1st Gen iPhones to 2.0 firmware, you don’t have worry any more. Click here now.
I upgraded to the version 2.0 and for almost a week I have been trying to get my phone to work again. Finally I have reverted back to version 1.1.4, but can’t get my service provider on the phone. The phone is like a ipod touch. can’t use the phone. someone please help.
Hmm… can’t downgrade here either because of the “iPod update server could not be contacted (-185),” which I assume is Apple blocking old iTunes versions from contacting them for updates. I’ve used Little Snitch to block the traffic and still no go, now I get the same error message as above, but with no error number. Stuck. Can’t use this keen phone with my uConnect car… argh!
Stefan,
Send me an email address and I’ll send what I have found on the net. I worked for me.
Hello everybody, who has a sollution for the non working service?
Help!!
[...] iPhone India Blog (en inglés) [...]
Hey thanx for all the help…..it was pretty difficult gettin the iphone in DFU mode but after i tried a zillion times i figured the trick was fourteen seconds exactly. My unlockin worked without using the winpwn or wutever i just used jailbreak 3.0 “do it all”. Now unfortunalety my problem is gettin my Phone Provider back on my IPHONE!!!! HELP!!!!!!
so..i uninstalled itunes 7.7, and installed 7.5, now i cant even open itunes. when i go to open it an error message reading something like ‘cannot open itunes library because it was made by a newer version’ or something along them lines. thats as far as i got. what do i do? somebody please help me downgrade. i need my installer back. help me!!!!
Lovely color people,follow this very programe very well,it has helped me alot,l stupidly updated my 1.1.4 iphone to this new 2.0 or whatever for 2 days,tried everything but only this steps get me through withz my windows XP.Bless
I did exactly what you did, however my problem now it’s that I have no service provider. My phone is saying there’s no service. By the way, if you use ziphone again it will install the intaller. I had the same problem so I re-installed it and it worked, but it is not allowing my sym card to work.
Thanks for your information
I have tried all these things and I still get error 20. Something is not working.
After 12 or so hours of trying different things, this method kind of worked for me, but I did some things differently.
I had an first gen Iphone, I guess its called. Not a 3g. I did this on windows Xp sp2.
1st.
I used total uninstaller to uninstall i tunes 7.7. This usually does a pretty good job of unistalling programs and cleaning up the left behind crap.
So after that I had to reboot my computer.
(Yes I am one of those people that will never reboot my computer because I hate waiting for anything. But in this case, after messing with this phone all day, I made sure to do everything by the book. You should do the same thing when troubleshooting that way you can repeat your steps exactly and actually know eliminate possible issues from your problem solving.)
2.Computer restarts, I have Zone Alarm Pro installed on my computer, which monitors when programs are trying to connect to the internet. So I turned the settings way up on this to make sure I would know every program that was trying to access the internet. I wasn’t sure if I wanted itunes to be able to phone home. Later I found out that sometimes it will phone home and then won’t let you use itunes 7.5, it will say you need to upgrade to 7.7
3. I installed itunes 7.5, I believe it did try to phone home, and I blocked it, and then it wouldn’t continue with the install, so I unblocked it, and as soon as it was finished installing I blocked it again.
4.I tried to start itunes but got a message popping up saying “the file iTunes Library.itl cannot be read because it was created by a newer version of itunes.”
5. I used the windows search function to search for Library.itl, and it popped right up and I deleted it.
6.I started I tunes 7.5, it did register my iphone, but said I needed to restore it. I had the screen up with the “slide to make emergency call, and the usb cord and the itunes symbol. I read that I needed to be in dfu mode, and this was not dfu mode.
7. So I put it in DFU mode. I am not going to explain what that is, I read what it is on alot of posts, if you follow the instructions, its not difficult.
8.So now I was in dfu mode, so I hit shift+restore in itunes to bring up the dialog that asks me what ipsw file do I want to use.
9.I seleceted “iPhone1,1_1.1.4_4A102_Restore.ipsw.” don’t remember when I got it from but I am sure you can find it if you look on the net.
10. It went through the restore process and did and everything it was supposed to do, and then I got a 1015 error, which from reading post, I read that this was okay.
***********************************
the first few times I tried this, I got different errors that different posts said were not alright. So I would leave it alone, go curse the world and then come back and try later. I don’t know why it worked this time, but it did, and it definitely wasnt on the first time. I had also installed and unistalled itunes 7.5 twice throughout the day.
so if this happens to you and you get the wrong type of error after the restore. I would recommend trying it a few times before you take a long walk off a short cliff. I am just as impatient as the next guy, but you have to just keep trying.
11.
So then I used the program winpwn, because it some post it said at this stage in the game, I should use it. so I did.
12.In winpwn 1.0 I clicked on the browse .ipsw button and then I browsed to the same file I used for the restore in itunes, “iPhone1,1_1.1.4_4A102_Restore.ipsw”. I had also downloaded some other versions of the .ipsw, earlier versions, and ipwner basically told me it didnt know what the hell I was talking about. So anyways, I used iPhone1,1_1.1.4_4A102_Restore.ipsw and clicked okay. It said a few things in the winpwn dialog box and then I new it was ready for me to hit the ipwner button.
13. So I hit the button and it said quote
”
Ramdisk successfully created
7/14/2008 3:35:13 AM – Sending ramdisk to iPhone.
7/14/2008 3:35:17 AM – Transfer took 3750ms
7/14/2008 3:35:17 AM – Modifying environment…
7/14/2008 3:35:17 AM – Starting pwnage
7/14/2008 3:35:26 AM – iPhone left recovery mode
7/14/2008 3:36:07 AM – iPhone entered recovery mode
7/14/2008 3:36:07 AM – Your iPhone has entered recovery after pwning!
”
***********************************
when I got to this point on another computer I was using, ipwner would crash everytime I hit the ipwner button. So on this other computer of mine it worked.
(yes the times next to the above quoted text are right, and I am on eastern standard time. I finally was making progress at 3am in the morning. So yes sometimes it will take a lot of work and time.)
14. So the last line told me that it went back into recovery mode after if finshed pwning(by the way, I have no freekin clue what pwning stands for, nor do I care, so if you don’t know, your a rockstar like me.) Anyways, I thought to myself,”back in recovery mode, Im screwed, drats, foiled again. Time to sell it on ebay, lol. j/k”
In one of my previous attempts, when I got to this stage, I was told by many posts, that I needed to knock my phone out of recovery mode here, and by the looks of things, it was still in recovery mode, so i used ziphone, ibrkr, and I liberty all at the same time(literally!), I used their various functions to kick it out of recovery mode. Needless to say this method did not work, but at 2 or 3 am, I was willing to sacrifice bricking my iphone.
15.Anyways, so now, I have done the ipwner thing but it put my phone back in recovery mode, I thought i was screwed blah blah blah, but I wasn’t. I actually used Ziphone 3.0 and clicked on the Do it all button and let it do its thing.
*****************************
I had used on Ziphone on a previous iphone so I thought I knew how it worked, as far as how long things should take. When I used it on this iphone at this stage in the game it took longer for the words to scroll down the screen and for the it to actally unlock the phone, I kept thinking it was frozen. But here is the KEY
A WATCHED POT DOESNT BOIL.
I literally flipped my iphone over and did not look at it. Previously as I counted the seconds go by and my iphone magic wasn’t working, I did things like unplugging it, restarting it, or running multiple programs at the same time, when I shouldn’t be “see step 14 for anecdote.” Waiting sucks, but once again, I would urge you to be patient, it even says on Ziphone, if this takes longer than 10 minutes then something is wrong. Well it didn’t take longer than ten minutes but it was close, but it didn’t even seem that long because I didn’t look at the phone every 2 seconds like I had been doing all day.
So next thing I know, I hear the usb chime on my computuer, the phone cuts off and cuts back on and, Voila!!, it works, I put atnt sim card in and I was ready to go.
note****************** the installer app was not on the phone when I finished, but after going through this all day, I could care less. I know I can install things later, “without upgrading”
Well thats it now I am going to go to sleep and wake up tomorrow and with my luck the 2.0 hack will be out.
Good luck to you all.
i have the dfu mode but itunes said tha the ipod software server could not be contacted error 185

search your drive for *.itl (probably located in your profile)
rename or move the file
relaunch itunes and it will re-create your library file. if you are sad about losing your library, don’t fuck with apple.
i have the same problem. it says it can’t open because itunes library was made by a newer version.
You must backup & erase your Music folder; close iTiunes, open Terminal and type:
mv ~/Music ~/Desktop
and open iTunes again, this must works
you have to name your itunes folder to itunes backup and then it will open itunes but i have been trying to downgrade from 2.0 all day and cant get it to work please let me know if you figure it out
The same thing happened to me. When I downgrade to 7.5 it tells me the library was made by a different version and won’t open. I had to install 7.7 again…
so..i uninstalled itunes 7.7, and installed 7.5, now i cant even open itunes. when i go to open it an error message reading something like ‘cannot open itunes library because it was made by a newer version’ or something along them lines. thats as far as i got. what do i do? somebody please help me downgrade. i need my installer back. help me!!!!
