I have an iphone with 2.1 on it that I am trying to downgrade, this is the 2nd gen and not the 3g. I tried using it with itune 7.5 but it didn't work. A screen popped up and said that I need a newer itune in order for it to read my phone, for some reason my carrier went from tmobile to carrier 2.6. Please message me back asap.
Thank You

just recently i experienced a problem with my phone. ive been looking all over the web and some people suggest that my baseband is corrupted.
gonna see if this actually helps. if not, im going to be needing a new phone.

*This is only for 1st Generation iPhones that have been upgraded... not for 3G iPhones*

1. Download iTunes 7.5 from here: Direct Download iTunes 7.5 to Activate iPhone Anywhere Internationally » My Digital Life
2. Uninstall your current version of iTunes and reboot your PC.
3. Go to My Documents > My Music > iTunes and delete the file called "iTunes Library.itl"
4. Install iTunes 7.5

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

5. Download the 1.1.4 restore file from the here Apple Forums & iPhone Forums, Mods, Hacks, News, Themes, Downloads, and more! | ModMyi.com - Downloads - iPhone 1.1.4 Firmware if you don't already have it.
6. Put your phone into DFU mode using the following steps
a. Plug your phone into iTunes (ignore the message that pops up)
b. Power the phone OFF
c. Hold power and home for EXACTLY 10 seconds
d. Release power (continue to hold home)
e. iTunes will recognize iphone in restore mode (you can let go of home now)
7. Hold shift and click Restore - select the 1.1.4 firmware file you downloaded
8. After it's done restoring you will get error 1015 and the phone should be in recovery mode (iTunes logo with cable)
9. Important! Hold shift and click Restore and select the 1.1.4 firmware file and RESTORE AGAIN.
10. After it's done open iLiberty "other tools" tab and click "jump out of recovery mode". (note - if you didn't restore TWICE as instructed above the phone won't jump out of recovery mode)
Note: On a Mac you can use Independence to kick out of recovery mode. Downloads - independence - Google Code

OK, you now have a phone with 1.1.4 Firmware and the 4.05.04 baseband. Now we have to downgrade the baseband

11. Download KiPhone
*Unzip all files into a folder before you run the program or it will fail*
12. Run KiPhone with Debug Boot and iErase options checked. (Leave the box for downgrade UNCHECKED)
13. Plug your phone into iTunes and shift+click restore to 1.1.4 AGAIN. This will write the correct 4.04.05 baseband to you phone. (You may have to put your phone into recovery mode manually for iTunes to let you restore - hold power and home until the phone reboots - continue to hold until you see the iTunes logo)
14. Your phone should now be factory 1.1.4 with the matching baseband - all you have left is to jailbreak/unlock with you method of choice.

I have an iPhone 2G that was dropping the Wifi constantly. Following this guide finally fixed it, after months of searching hi and low for a solution. I was so convinced it was a hardware problem, I bought some tools in order to try and identify a loose connection or something.

Going back I recall what might have gone wrong. I had jailbroken 1.1.3 firmware, and then updated to 1.1.4 and then 2.0. The update to 2.0 is what broke the stability of the wifi. What I should've done is "virginize" the phone and then update to 2.x.

Thanks again Poseidon for the great post.

at what step do i start the kiphone

[glassofmilk]

i have followed these steps EXACTLY as shown however the download link for KiPhone is not working. I know I must need your copy of it because I downloaded it elsewhere and recieved this message when running the program:

"Searching for iPhone...

This application has requested the Runtime to terminate it in an unusual way.

So if someone could show me where to get the correct version of KiPhone I would really appreciate it.
