02-08-2010, 12:18 AM #1how to restore iphone 3.1.2 without update
I jailbroke and unlocked my AT&T iPhone 3G on 3.1.2 the other day (with blackra1n) and it worked ok until just now, when it won't turn on anymore. I can only get as far as the apple logo.
I'm trying to restore the phone but, when I hold down the home button and connect up to iTunes, the only choice I get is "Restore and Update" and I'm concerned that it will upgrade me to 3.1.3, which I understand can't be jailbroken or unlocked.
Is there a way to restore my iPhone to 3.1.2?

He has a 3G not 3GS all you need to do is hold down the shift key while pressing the Restore button in iTunes. Then manually select the 3.1.2 firmware file. (you need to download the FW file before restoring)

Thanks for noticing my 3G (not 3GS) problem.
I had posted after having held down the shift key but iTunes didn't give me a "Restore" button. Instead, it gave me an "Restore and Update" button without an obvious manual override to use the 3.1.2 firmware.
I'm concerned about pressing the "Restore and Update" button since I think it will just update my firmware to 3.1.3.
Am I being too conservative (and I should just press it) or am I missing something? (I've downloaded the FW file but have kept it on my USB flash drive - is that ok?)

Just <shift> click the button, it will pop up a screen that is looking for the ipsw file.

Is there another way I can get the details regarding the baseband, bootrom, etc.?
When I attach my iPhone to iTunes (after pressing down the Home button), I get the iTunes icon on the iPhone and a pop up that says:
iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.
There is a button that says [OK], which I press (I've also tried this with the SHIFT key down although I'm pretty sure it's not the one that matters but I've run out of ideas...).
After that pop up goes away, I press and hold down the SHIFT key while I press the [Restore] button on iTunes but, instead of the pop up you describe, I get one that says:
Are you sure you want to restore the iPhone "iPhone" to its factory settings? All of your media and other data will be erased, and the newest version of the iPhone software will be installed.
It also says iTunes will "verify the restore with Apple" etc. The only two buttons it has are [Cancel] and [Restore and Update]. There is no restore-only button and nothing about ipsw.
If I press the [Restore and Update] button, it goes right inot a pop up telling me it will be updating to 3.1.3.
Where can I insert a request to go back to 3.1.2's ipsw?
I'm using iTunes 8 - could that be a problem?

If you are on a Mac you hold option key instead of shift. If you are in windows you may have to run iTunes as admin.

If you're nervous about trying, just locate the directory where iTunes stores the ipsw and delete it if the 3.1.3 is there. Then you won't have to worry about doing it wrong because even if you do, iTunes would still have to download the 3.1.3 before starting the install and you'll have plenty of time to stop the process.

Thanks for the advice - it was the Option key I needed to press!

Same issues ... So did it work? Where would I find my 3.1.2 ipsw file on Mac?
Thank you in advance.

It did work! I googled "download iPhone1,2_3.1.2_7D11_Restore.ipsw" and grabbed one of the files there. I can't remember which particular site it was but I didn't have a problem with the first one I found (which may have been: MyTopFiles - Misc - iPhone1,2_3.1.2_7D11_Restore.ipsw)

I too have exactly the same problem as cyboj. I have my SHSHs stored with Cydia (according to Cydia they are) I've modified my hosts file (along with a ping to check that it's going to Sauriks server) and I've tried running iTunes as administrator. Everytime it's the same, I only get the 'Restore and Update' option, which tries to force 3.1.3 on me.
I'm on Windows, so I know that 'shift' is definitely the right button to use. I'm currently on 3.0, jailbroken, model number is MC131X and my baseband is 04.26.08. If you need any more info just ask.
Please help!! I'm going crazy trying to figure this out!

Well that's just real helpful. I've read the entirety of this thread, as well as many other tutorials on the subject. But to placate you I'll run through point by point:
hold down the shift key while pressing the Restore button in iTunes
Just <shift> click the button
If you are on a Mac you hold option key instead of shift.
If you are in windows you may have to run iTunes as admin.
It did work! I googled "download iPhone1,2_3.1.2_7D11_Restore.ipsw" and grabbed one of the files there. I can't remember which particular site it was but I didn't have a problem with the first one I found
Or are you referring to the tutorial linked to this thread where the advice is to change the hosts file (yet again, tried, yet again in my post) and then Restore (which gives the exact same result as the above).
So where exactly are these elusive answers you refer to?

I dont know about you Stevvers, but I had the same problem and this thread pretty much answered all the questions I shift-clicked the restore button in iTunes then selected the 3.1.2_restore ipsw. It looked like it was going to work but then i got a message that said "The phone "iPhone" cannot be restored. An unknown error occurred."
I am running XP and yes I am an administrator.
My phone is a black 16gb, and i have updated it with every update apple has put out, with the exception of the most recent.

Can I use a custom firmware to upgrade from 3.1.2 to 3.1.3 on my AT&T 3GS?
