Estas son las instrucciones para hacer un firmware downgrade en tu iPhone usando un SHSH guardado en Cydia y con Windows.
Para que funcionen estas instrucciones, sin embargo, es necesario que le hagas echo jailbreak en una version anterior del firmware y que hayas abierto Cydia permitiendole guardar tu SHSH en un archivo. Para mas informacion acerca de esto, dirigite a: here
Primer Paso Click derecho en Block de notas en Inicio - Programas - Accesorios.
Segundo Paso Elige Correr como administrador del menu desplegable.
Tercer Paso Una ventana va a aparecer preguntandote si te gustaria darle acceso al sistema al Block de notas. Hace click en el boton Si.
Cuarto Paso Una vez abierto, selecciona Abrir... en el menu Archivo.
Quinto Paso En el desplegable elegi ver todos los archivos y navega hasta C:WindowsSystem32driversetc y selecciona el archivo hosts. Hace click en Abrir.
Sexto Paso Anexa 74.208.10.249 gs.apple.com al final del archivo.
Septimo Paso Selecciona Guardar en el menu Archivo para guardar los cambios.
Ahora estas listo para hacer downgrade a tu aparato. Simplemente pone tu iPhone en modo DFU y en iTunes hace Shift+Click en el boton Restaurar para seleccionar el firmware al que te gustaria hacer downgrade. Si te da un mensaje de error 1011 o 1013 ignoralo. Si te da el mensaje de error 1015 repeti la restauracion y luego hacele jailbreak luego de que haya fallado por segunda vez.
*Muchas gracias a Saurik por hacer estos downgrades posibles.

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.
Hi does anyone get an error(13)? I had an 3.0.1 running and then downgraded..or rather upgraded 3.1.3 - and that worked but when i tried to install 4.0 or 4.0.1 it's says erro(13)?
Thanks in advance!
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!

Hello Everyone! I'm trying 2 downgrade my 3GS from 3.1.3 to 3.1.2...but its stuck at "verifying iphone restore with apple"....ny ideas on how to overcome that? I would appreciate! Thanks
i cant save the edited hosts file.. it keeps converted to txt format.. and ended up with two hosts file.. the original (hosts) and the edited (hosts.txt). what should i do? thanks in advance
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
Having the exact same problem! Is this most likely because my device was never registered with cydya and doenst have an SHSH ECID? any help is appreciated.
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!
i don't know if i saved my shsh file to cydia..? (dont know how to do and how to check it, im noob) but, i try downgrading my iphone 3gs 3.1.3 back to 3.1.2.. it downgrades succesfully! but its still in 05.12.07 baseband. my question is, can i unlock it with the new firmware?? -i already jailbreak it using blackra1n rc3, but im not yet trying to install cydia and unlock.
after downgrading..
**iPhone 3G[S] 3.1.2 - Firmware 05.12.07 +blackra1n RC3
@ Art - the process is still the same in windows7 64, but rmember when opening notepad to "Run as Administrator"
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
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
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"........
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)
have followed all of the steps, including the download to my desktop of the 3.1.2 restore, but when i try and shift restore from i-tunes i can see the folder etc but get a message no items match your search, can anyone help me finnish this please ?
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
what is error 1015?
after i restored with the ipsw-file, i got: "the iphone 'iphone' cannot be restored at this time because the iphone software update server could not be contacted or is temporarily unavailable."
what did you do after you ran it again?
thanks
