Well... I want to go from iTunes 7.7 to 7.5 to downgrade my device to 1.1.4. What I', running into is an error message after installing 7.5. When I uninstalled 7.7, I rebooted, then installed 7.5. The error message I get is "The file iTunes Library.itl cannot be read because it was created by a newer version of iTunes."

I wanted to delete this and reinstall, but I can't find it. Is there something I'm doing wrong? Help!
 
Before attempting to launch iTunes 7.5 for the first time you need to delete or rename the iTunes folder..

Windows:
Rename the C:\Documents and Settings\**your user name**\My Documents\My Music\iTunes folder to iTunes Backup.

Mac OS X:
Select the iTunes folder in your Music directory and rename it iTunes Backup. You press the Enter key to rename a file in Mac OS X.

:apple:
 
Its best if you rename those folders to anything OTHER than iTunes, that way 7.5 can create its own new iTunes folder which you can delete when you go back to 7.7 and use your old renamed folder again to be back where you started

If you delete the folder you lose all media/settings

To do what? are you using a mac and did make sure to rename the folder before ever launching iTunes 7.5. It seems 7.5 is still trying to use your 7.7 library instead of creating its own. My advice, quit iTunes move ALL iTunes folders in the music folder to another location (even trash/recycle bin temporarily but dont deletw) and then launch 7.5 again

I apologize. I am using Vista on a PC. iTunes launches now. The issue is the error I get because of the 2.0 software that is on the iPhone (my assumption). Are any of the 2.0's supported? 2.0, 2.0.1, or 2.0.2 by iTunes 7.5?

Nope. This is where you downgrade your phone to 1.1.4 by putting the phone in DFU mode, using shift+restore and then selecting the 1.1.4 firmware. NB this only works on on-3G iPhones

What does NB mean?

Also It doesn't even show me the iPhone within 7.5 to do this. The error prevents the iPhone from being recognized.

Is the another way to downgrade aside from using iTunes?

NB means Note. Its not showing because you haven't put the phone in DFU mode

Use the following guides and follow them carefully.

Guide 1

Guide 2

R u sure you entered DFU mode?...if you did then do as it says uninstall iTunes, reboot and then re-install 7.5 and try again or brave 2.0 firmware till tues. I'd like to help but the fact that you're running vista means some other things maybe happening in the background that i cant comment on (i use a mac)

Uninstall iTunes, reboot, remove ALL iTunes folders in your music folder, install iTunes 7.5, launch it (it wont want to recognise the phone), put the phone in DFU mode and then proceed from there.

If that doesn't work then i dunno what else to say
 
Thanks for helping. I guess I'm SoL. :(

It's almost like I will have to update/activate through iTunes, which I can't do as I don't have a spare sim or spare line (don't want to mess up the ugrade eligibility.)

Im surprised it still didn't work for you. Have you read this sticky, maybe it'll give you some more info

It's good to go. The only problem I may have is the tmobile sim card I put into the iPhone is saying "no service" but I will look into that when I get home.
 
I have two iPhone 2g devices that I downgraded to 1.1.4 on. My issue now is that both do not get service. I am able to connect to wifi though.

I put both my at&t sim and t-mobile sim and still no service. Am I doing something wrong? Should I be upgrading to 2.0 now?
 
I have a belief it has to do with unlocking the baseband. One of the iPhone's did not have 2.0 and this was the one that is now working after using BootNeuter. The second one in which I did d/l 2.0 and now back to 1.1.4 is the one that I can't use BootNeuter because I upgraded.

I am correct in this belief?

Yeah you need to have used Bootneuter before upgrading, if you didnt then here's and excerpt from Guide 2

"Step 6) 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. Unfortunately, this only works if you have neutered your phone before the upgrade. If you did not, you will have to follow the steps below instead.

If you get a boot neuter error like 05, 02 or such, you need to follow these 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. Direct download link for pc and mac and instructions for use.

Troubleshooting:
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."

If you plan to downgrade anything/anytime then using Bootneuter would make it easier
