I am new to this forum, please do not bash me for not searching i just have a question, im just asking for an answer.

I have an AT&T account so i am not interested in unlocking my iPhone for a different carrier ect.

I am trying to downgrade from iPhone Firmware 1.1.2 to iPhone Firmware 1.1.1 but I am having some problems.

I plug in my iPhone, open iTunes, Hold the Home and Lock buttons then hold Hom button to get it into DFU recovery mode, I then click ok on iTunes and then "option" click restore and click teh restore1.1.1.ipsw file, the restore goes completely through and ends with the usual error "1015", this is where im stumpted.

my iPhone is then in DFU mode with the iTunes and Cable connector screen, and my iTunes prompts me to restore again, all these guides say use iNdependence, but iNdependence is not compatible with iTunes 7.5 which I have, it also says you can use iPhuc which is a terminal program which I am not familiar with, even though im not familiar I typed in the commands and nothing happened.

So to sum it up, i can downgrade all the way to teh end but then i cant kick my iPhone out of the DFU mode.

could someone help?

Firmware 1.1.1 won't work on 1.1.2 baseband.
So, in order to work with 1.1.1 you'll need to virginize it to 1.1.1 aka. downgrade baseband. (only if thats not OTB 1.1.2, if it is - none of this works)

Edit: And use iNdependence 1.3 beta. Works like a charm with iTunes 7.5.

I've published a very easy tutorial on 1.1.2 downgrade here: http://iphone.unlock.no/#how-to-downgrade-1.1.2

On windows, you can easily get it into normal mode with AppTap.

I'm not sure how Independence works, so it would be nice with some feedback from mac users...

Error 1015 is expected. What you got to do is, download a older version of iTunes to make it compatible with inDependece or go get the older version of MobileDevice. The other way which is better then independece IMHO is iPHUC.

Go download it. Install and run it with your iPhone connected. It should show recovery mode. Then type these commands one by one:

cmd setenv auto-boot true
cmd saveenv
cmd fsboot

Wait for awhile. Maybe for a minute. The connect to itunes graphic will disappear and you should be out out of DFU mode.
