iPhone 3GS 3.1.3 Downgrade to 3.1.2 method to be released?

[stewart262]

K so i've spent hours this morning trying to figure out how to downgrade. No luck obviously. So i was wondering, what will most likely come first?
a jailbreak for 3.1.3 or a method to downgrade 3.1.3 to 3.1.2

is there a chance apple may allow users to once again downgrade?

You can downgrade right now if you have your shsh files on Cydia. Other than that, there's no way and there won't be.

So to answer the question, if any of the two happens, it'll be the jailbreak.

Final answer, Apple will never allow downgrading again.

i think we should wait blackra1n ........ no way to downgrade :S

5. close itunes with iphone still connected
6. run redsnow, browse to firmware select yes for new model and "run tethered boot only" do not install cydia
7. wait for phone to boot now you have working service through ATT and 3.1.2 firmware. ok to update carrier settings.
8. shut down phone and reboot now your back to itunes connect screen
9. run blackrain and install cydia

when i used redsnow to install cydia i experienced 3 crashes, one after installing caller id faker and another after a winterboard theme and another iphone just froze and had to re do the whole process. since installing cydia through black rain now problems as of yet. only thing i have noticed as of yet is when using openssh and ifunbox iphone is stated as jailed however when i used redsnow and jailbroke and installed cydia it was stated as jailbroken but i expericned 3 crashes. i also had trouble with 3rd party apps immedialty crashing and was able to resolve by setting up as new iphone in itunes. right now with the method described above and the following ctydia apps my phone has been working flawlessly.

dhamien looks like our question about redsn0w and blackra1n is answered.

Yeah, I guess that's it. Blackra1n does something that prevents the phone from activating whereas redsn0w doesn't. Good to know =)

Can't restore to 3.1.2 . am not sure my phone have sHsH file store at

Hey,
it is really easy to downgrade an iPhone from 3.1.3 to 3.1.2...

There are a few things you have to Download before you start:
-iRecovery
-libusb-win32-filter-bin-0.1.12.1
-iPhone Firmware 3.1.2
-Blackra1n (if you wanna jailbreak your iPhone)

The first thing you have to do is to change a file in windows.
It is the file hosts. You can find that file here:
c:/windows/system32/drivers/etc/
you have to open that file as admin.
In that file you have to go under the last line n add this:
74.208.10.249 gs.apple.com

If you have changed that restart your Computer.

After the restart you can open iTunes n then you put your iPhone into DFU-mode. (hold power+home for 10 seconds n then hold only home for 10 seconds)

Then you have to hold the shift button and press restore in iTunes...the you have to choose your downloaded firmware 3.1.2

iTunes will restore your iPhone then...after you have done that you will get a message that it didn't work. (1015 code)
But this is Normal!

Now you have to install libusb...when it's done open lib usb and then run cmd from windows.

put irecovery on the desktop n then do that:
You will see there c:/Users/yourname>

You have to add this:
cd desktop
irecovery -s
setenv auto-boot true
saveenv
exit
reboot

After that your iPhone will come out of recovery mode n it is done!

You can now (if you iPhone is activated then) jailbreak your iPhone with blackra1n

This is all covered in the guides section. Also, this only works if you've stored your SHSH files.

3G phones don't require signing. Neither does old ipts. So ...

[iYeow]

You can't go to version one for 3g.

[jawad11]

Hey Mr. why you want to downgrade ur iphone to 1.1.4 !!
1- your current version is jailbroken using Spirit Jailbreak Spirit , and unlockable using ultrasn0w
2- if ur current version is broken and damaged u could restore to 4.1 or 4.2.1 i dont remember , without need
to shsh then jailbreak it usind JailbreakMe 3.0 or redsn0w and unlock by flashing ur baseband to 6.15
3- more tutorials are found on iClarified - Apple News and Tutorials ( jailbreak and unlock wizard )
