I got stuck in DFU mode (displays connect to iTunes or screen is black) after downgrading from 4.1 to 3.1.2 and got error message 1015. It was a little bit unclear in this article, but you can run your jailbreak tool (e.g. RedSn0w) even if you're stuck in DFU mode.

Tried to downgrade my 3GS on 3.1.3 with Spirit JB to 3.1.2 using my Cydia SHSH blobs to be able to re-jb in order to be able to jb on iOS4, but the restore fails for some odd reason :-/ It runs for a good while after I select the iPhone2,1_3.1.2_7D11_Restore.ipsw, then stops with a message that says: "The iPhone "iPhone" could not be restored. An unknown error occurred (1015)". Anyone with an idea? Many thanks!

Did you just follow the steps posted here? I've tried it a few times & keep getting a message saying the device isn't eligible for requested build, running out of options now, stuck on 3.1.3

and btw, my iPhone 3G is upgraded to the latest 3.1.3 - does that mean that if I want to downgrade it to 3.1.2 or unlock/jailbreak at 3.1.3, I need to also downgrade the baseband? Thanks!~

I've done all 7 steps and have had my iPhone 3G (locked AT&T, 3.1.3 version, never been unlocked/jailbroken) in DFU mode. Though iTunes does not allow me to downgrade it back to 3.1.2. I don't have a Mac so I can't use the Pwnage Tool for 3.1.3. Any clue as to what else I should do to downgrade it? Thanks a bunch!

the way you tell if cydia has your hash files is when you sign on to cydia on the top it will say this device has SHSH on file for fimware(s) blah blah blah

Is the it the same process for Win 7 64 bit? Does any one know? Thanks.

I now have the correct firmware file, I now get the message "iPhone cannot be restored as it is not eligible for requested build", think I'm stuck on 3.1.3 for now as I've tried a few times & this always happens

Read steps 4 5 6 and 7.. If u edit the right file and append the right thing, it will not check with apple to see if that's the right firmware.. It will insted check a fake server that will allow u to use the 3.1.2 firmware
Shamanwee
Shamanwee - February 22, 2010 at 1:09pm
I had the same issue with Baz Reed....i follow the same thing as step 4 5 6 and 7 but still get the message "iPhone cannot be restored as it is not eligible for requested build"........

DonWan - February 19, 2010 at 9:22am
All those having problems with the firmware file is because it is in .zip format. U must rename the file with .ipsw as the extension.... (so its not a .zip)

i followed the tutorial for downgrading my 3gs as i had a problem with cydia. Everytime i hold shift then restore the firmware wont open in the folder i saved it in. It doesnt look anything like the firmware on the video tutorial (a cube shape) its just a folder with a zip on. Im using windows vista, any advice would be great thanks

WORKED !!!!! This is how i did it.. Followed directons 100% got error 1015 at the end.. ran it again, got error 1015 at the end again "phone was still in recovery mode", then i went strait into jailbreaking with blackrain. WOrked fine other than at the end of jailbreaking it froze with buddies picture on the screen, i rebooted phone, connected to itunes, it activated and was jailbroken with cydia in the springboard. This was done on a iphone 3gs(old bootrom). accedentley upgraded to 3.1.3 through itunes. manged to downgrade to 3.1.2 and rejailbreak
