Can I downgrade my 3GS to iOS 3.1.3 from ios 5. If so how do I do it?
Apple refuses to allow users to make their own decisions, so no, you can't. If you ever want to be able make your own decisions, Android would be ready to help!
What has that got to do with anything? The OP is talking about iOS.
No, or at least not officially, and this is why:
Shhhhhh you're interrupting the Android advertisement.
I don't think you can go backwards on iOS. Erase and Restore maintains the current OS.
Nope you can not.
I was able to but I'm not sure if it's a guaranteed way. I download the firmware I wanted, pressed shift and restore, chose that ipsw and then when it finished restoring it says it can't reboot or iTunes detects a iDevice in recovery mode. At the time you open redsn0w and follow the jail breaking directions then at the end you'll be downgraded. (it worked on my iPhone many months ago.)
You can only downgrade if the earlier version is still being signed by Apple - assuming you are NOT jailbroken.
If you're jailbroken, if you have an older phone (like my 3Gs) you should be able to downgrade to any earlier version of iOS for which you have the shsh blobs.
The only downgrade you can get to is iOS 4.1, which Apple still weirdly sign for the 3GS - although I haven't checked the status of this in a while. Otherwise it's a no-go unless you have SHSH blobs.
But why do you want to downgrade, anyway?
Especially that far back? Did iOS 4 work well at all for you?
The only way would be if you had the SHSH blobs saved for 3.1.3. Otherwise, it is impossible. Although I have been able to downgrade a 4th gen iPod touch before without the blobs...
