Invalid response from itunes


Apple is not supporting the earlier models of iPhone with the later versions of iTunes.

iTunes provided this error message "iTunes could not connect to the iPod touch because an invalid response was received from the device." using my Generation 1 iPhone (2007) and iTunes version 12.6.0.100

There are two solutions for this, either find an Apple computer running an earlier version of iTunes, or find a PC version of iTunes that is earlier than version 12.

I found iTunes Version 8.0.2.20 for the PC (64bit) and that worked fine on my Win8.1 PC.

Caution - If you try to reload iPhone firmware holding down the power plus home button, and keeping the home button pressed, but you dont have a working iTunes - you risk "bricking" the iPhone until you can reload the firmware with an older version of iTunes.

The FileHorse website provides many older versions of iTunes for the PC.

I would like to downgrade firmware on iPhone 3G from 4.0 to 3.1.1 Please help


There is no 3.1.1 firmware version available for the iPhone 3G. 3.1.1 is only for ipod touches. To downgrade to 3.1.2 (http://modmyi.com/forums/downloads/firmware/6/iphone-3g-3-1-2-32353/) or 3.1 (http://modmyi.com/forums/downloads/firmware/6/iphone-3g-3-1-32183/), download from either of the provided links, go into iTunes and to your iPhone tab, shift+click on restore for windows, or alt+click restore on mac, navigate to the downloaded file, and open it. Your phone will restore to the downloaded firmware.

That is DFU mode. It's there for software upgrading/downgrading. If you can't get out of this mode, reloading the firmware from Itunes will release it.

Open up Itunes.
Connect your IPhone.
Select your IPhone in the left window frame.
Press the "Check for Updates" button located in the summary frame.
Click "Download and Install."
Don't disconnect it while it's doing it's thing.

Once it finishes you will be out of DFU mode.

Hope this helps,
BReady

My iphone 2g currently running 2.0.2 firmware after jailbreak received msg on screen ''Repair Needed'' contact apple/support pls help


Contact apple and say you tried to downgrade your firmware but you downloaded the firmware from a internet site because iTunes wouldent download.
The error is in the CPU can be fixed by going into DFU mode and restoring .
Google "How to put iPhone/iPod Touch into DFU mode"

Iphone not detected in itunes8.2.0


Hi, welcome to fixya! I've read a lot of blogs about itunes 8.2 which is the latest version of itunes. The problem is when you update your iphone firmware and when it restarted your iPhone will be locked up, so beware of that. Why don't you uninstall your updated iTunes and install the 7.6 version and run the process. If still nothing detected, if you are using PC computers transfer your USB connection at the back of your CPU, cause front and back connection has a power speed difference. Try it first before downgrading your iTunes to a 7.6 version.

This is how really people downgrade from firmware 2.0 to 1.1.4 on an First Generation iphone. all other videos just show what you have to do if you use a touch or if you have a at&t sim. Now dont forget that the extra steps are just for people that have the iphone with t-mobile.
Before you start make sure your phone is not on DFU or restore mode... and Itunes has detected your iphone...
You need to have an ATT SIM Card from an active phone for downgrade (it doesn't have to be yours)

1) download link.
http://www.filehippo.com/download_itu...
http://download.ziphone.org/
http://www.modmyifone.com/forums/down...
the next file is only is you have t-mobile.
http://www.mediafire.com/?oxyhnldjm1g


2)Uninstall itunes

3)Install the itunes that was downloaded from link

4)Go to start menu, my music, itunes. change the name of a file called iTunes Library.itl to iTunes Library.itl9

5)open itunes, make sure phone is detected by Itunes and restore iphone by press down SHIFT , clicking RESTORE bottom at the same time, and select the file that what download that should say "iPhone1,1_1.1.4_4A102_Restore"

6)After the restoration, an error number '1015' may come up, that okay its part of the downgrade. After downgrade is done, ur phone should be on recovery mode

7)Open ziphone from your desktop and click the "do all button".. it will take like 5 minutes if if takes more than ten minutes go back and start from step 1. After this process is done your phone should be unlock.

8) If you are a at&t customer then your done. but if u have TMOBILE follow the next steps

9) Close all applications; (iphone and ziphone). Click on the file that was download that say "KiPhone" unzip it and start the app. that says this "ZiPhoneGUI - patched by kIREmK". once open you need make sure you select "downgrade baseband" and "debug boot" and then just click start. THis process may take several minutes.

10) After Kiphone has finished now you have to redo steps 5-7.

11)now this is for both at&t and t-mobile user go back to start menu, my music, itunes and rename the file that u changed in step 4 back to iTunes Library.itl
