Getting Back from iOS 5

[Dumbledorelives]

I'm not sure if my UDID is registered right now, but I think it might be - though I am not a paid developer. If I attempt to install iOS 5 and it turns out my UDID is not registered, is it easy to back down to 4.3, or will my device actually be a brick? Assuming I have my SHSH saved in TinyUmbrella already, of course. Thanks.

I'm in the same boat as you. Awaiting responses.

I wish someone replied because I'm in the same exact boat. I'm sure you can just restore it. Ill wait for a definite answer though

Yes, you can restore it. I just did earlier today. I was supposedly registered but it didn't work.

You just have to enter DFU mode while connected to your computer with iTunes running, but make sure you have a downloaded copy of the 4.3.3 firmware that you can select in iTunes to restore.

You can find the links to the 4.3.3 firmware here:

It wasn't that tough. Then just restore from a backup once it's up and running. Your music and apps will have to be reloaded, but it doesn't take that long.

Good luck.

This screen cap was taken from the iOS development center and you must read it before you download any of the iOS's 5 betas.

According to Apple, it can't be done. So any efforts to downgrade would have to be extremely difficult and might result in improper functioning of your iPhone. Some people have had success in restoring and others were left with expensive paperweights.

Don't install it on your everyday use device, there's a reason why this is a closed beta for developers only and for testing only on development devices.

Mine downgraded without a hitch, and surprisingly my baseband is also back to 4.3.3

Using a 3GS

I'm sure you know a lot more about this than I do - that's not sarcasm - but doesn't Apple also claim it's not possible to go from iOS 4.3.3 to 4.3.2? They always say you can't downgrade, but as long as you have your SHSH blobs you always can...I think I'll go for it.

Keep me posted. I'm about to as well.
