Have done it on iPhone 3G[s] which was on 3.1.3, jailbroken with Spirit and upgraded to iOS4.0! Downgraded succesfully to 3.1.3 again used Spirit and Ultrasn0w to unlock. I did have SHSHs for 3.1.3 and my iPhone has an old Bootrom! Gluck to everyone else!!!

actually you can do it on mac & windows with a 3GS - especially if you've jailbroken your phone before.

http://www.ihackintosh.com/2010/06/downgrade-iphone-3g-3gs-ios-4-gm-to-os-3-1-3/i did this a few weeks ago with my 3gs so i could jailbreak / unlock and sell on ebay.

Ohhh man thank god i didnt update my phone to 4.0, i always knew there was gunna be bugs. After just seeing the last comment, if we can actually downgrade 3gs from 3.1.3 to 3.1.2 then we should be able to jailbreak our phones on 4.0 right ? Thats what i got told anyway but personally do you all think its best to stay on 3.1.3 ? No probkem at all with my phone at the moment, i dont really want to make a hassle with it.

shsh blobs don't matter with the 3g phone
-
did everyone backup their phone?
-
How well did this work for everyone? Did it in fact speed up the performance? I'm about to attempt!
-
This apple **** makes me hate life. U can't do this u can't do that Fu apple and all u control freaks.
-
I will be downgrading due to many, many apps that are not compatable anymore. The speed is only an issue if you enabled Multitasking during RedSn0w installation.

I cannot seem to get it to restore to 3.1.3. On a windows machine, I hold down shift and click restore, but it only wants to restore to 4.0. No option to restore back to 3.1.3. Has anyone else had this issue?
-
I restored my old bootrom 3gs to 3.1.2. Then I jailbreaked it with blackrain updated to ios4 with custom firmware and now unlocked it with ultrasnow. Lengthy process but worked smoothly. Now I have a iPhone 3GS ios4 jailbroken and unlocked!!! Yeah now ready to sell this bad boy
-
Just want to thank you for posting this. Upgraded my 3G and was too sluggish. Now back on 3.1.3, much happier
-
I am running win 7 x64 and that side program that must be installed literally fkked up my entire comp system.. I dunno what it did but everything is screwed up, I gotta boot from my cd drive now... x64 users, bewaree!!
-
Can I restore my 3GS upgraded to 4.0 back to 3.1.3 I saved my shsh?
-
What did?
-
What is the deal with the time delay on this site?
-
what about if you saved you shhs to your local computer destop??? file extension is .shsh
-
You must have done something wrong. I followed the directions for the x64 systems and I'm currently restoring to 3.1.2 as we speak with no issues booting up or anything.

this doesn't work worth a ****...... i have jailbroken and unlocked and downgraded and you name it and this tutorial does not work worth a ****!!! I am on windows 7. downloaded libusb, recboot, and net 4.0....hit the button in dfu mode and nothing happens. what a waste of time. sorry venting i am mad right now
-
-
Hey guyz, I'm having trouble with the libusb, it doesnt seem to b installing, anyone had a similar problem???
cheers -
I can't get Recboot to work. I have followed all the directions. Any suggestions?
-
Make sure you download the libusb.exe file. The link in the tutorial didn't work for me. I just googled libusbwin32. I can't remember the link I used, sorry.
-
Yes you can as long as you follow the instruction. I have a iPhone 3gs with ios4 and was able to downgrade back to 3.1.3. Then I was able to jailbreak and unlock my iPhone again.
-
what do i need to use to jailbreak 3G on 3.1.3, on mac or pc (mac preferred)
thanks so much :)
-
I can´t install LibUSB. Does anyone have a correct installation guide?
-
I downgraded my 3G to 3.1.3 and all went well until i tried to jailbreak it with redsn0w. I am now getting the "Unable to recognize specified IPSW" I am using the right version of 3.1.3 IPSW and i tried it with all the redsn0w version 9.3, 9.4 and 9.5
Has anyone else had problem jailbreaking after you downgraded from iOS 4 on 3G?
