i've been trying this method, but it isn't working exactly as it should.
please correct me if i'm wrong..

1. i take an 1.1.3 OTB phone and restore it to factory defaults.
2. Then i immediately try the method OP has suggested..
1. Connect iPhone to Mac/PC - keep iTunes open
2. hold down power and home button
3. wait until red slider appears to shut down iPhone, keep holding down the buttons, count 4-5 seconds (while iPhone shuts down)
4. release power-button, keep home button pressed (there should be no Apple logo! If it appears, you waited too long to release the powerbutton - try again )
5. wait 5-10 seconds - iTunes should then prompt that there's an iPhone connected in "restore mode" - but it's different!


is this the way or after the 1st step i need to unzip and run DFU.
Guys please help, i've been battling with this error 1 issue since yest.
My apologies if it sounds absolutely basic

thanks in advance.

Wish I had found this last nigh when going around the twist with error code 1

This below is a repost of what I posted on a local mac forum of mine:

When downgrading firmware iTunes is giving an error code of 1 & 1015.

The error code of one is because you have not put the phone in proper DFU mode to downgrade. This has nothing to do with iTunes version and has only come up especially when downgrading from 1.1.3

Here is how to properly put your phone in DFU:

This is how to achieve DFU mode. You can do it on every phone:
Attach the phone to the pc
Turn the phone off
Hold power and home together for *exactly* 10 seconds
Release power but keep holding home until the pc beeps as a USB device is recognized.
At no point will the display come on. Now your restore should work.

When you finish you will get an error code of 1015 this is normal but you will not be able to boot the phone. Try any tool iPhuc, iNdependence, iBricker etc etc. The phone will still be in recovery mode boot loop.

Do a second restore using the option key on mac or shift key on windows.

After your second restore is finished you can close iTunes & boot you phone with iNdependence or iBricker.

This affects all iPhones regardless of bootloader and especially FW 1.1.3 downgrade. It has nothing to do with iTunes version or mac or pc. I have tested this on mac & pc in several different operating systems.

Unless you dont put iPhone in proper DFU mode you will get error code 1 on a downgrade.

For Moderator, this one should be moved to sticky as not many people has know the difference.

I have been reading this forum for about a month before I ran into some thread mentioning about this difference. But this Tutorial should help. Or move this to the Tutorial section.

Can somebody give us any solution for this error. I understand I've erased my baseband (thats what iNdependence tells me) so can any one tell me how to fix this (if possible) its OTB 1.1.2, and right now I can't do anything with it. Allways same error 1011 now

If what you said is true i.e. erased baseband, I read from other forum is that you can restore to 1.1.3 and then downgrade again to 1.1.1 and so on to do unlock again back to 1.1.2 unlocked, then softupgrade to 1.1.3

SPACKY2K!!!!it is not dfu mode you are mentioning. dfu mode is the "white screen" on iphone

that you get through ibrick or by uploading necessary files and giving necessary

commands, you force your phone to dfu mode which is totally different than

restore mode that you get by pushing home and power button

simultaneously...

When you get the white screen you click shift+restore button to succesfully restore your phone.

1-After restoring, youll have an 1.1.3 WORKING iPhone.

2– Download DFU - www.send$pace.com/file/93fx93 (change $ to s)

3 – Extract DFU folder to C:/

4– Go to the start menu and click Run, and type the following:
c:/dfu/dfu iBSS.m68ap.RELEASE.dfu
Now hit OK, this will force your iphone into DFU mode. Now it should have a white screen.

5 – Now click shift restore on itunes and Select 1.1.1 file. (I did this restore twice, so its up to you.) Now itunes will say that your iphone is in recovery mode. Press OK.

The thing is that the iPhone is not responding, I do the Hold/home button restore and at the end of the progress it gives me the 1011 error.
Do you have any idea of what I could do.
Thanks

you didn't actually read my tutorial

btw white screen = black screen - DFU mode is absolutely the same.

thank you very much!
