Going from iOS5 beta back to current public release...

As I Understand It

You are correct. Click the button where it states restore if you are experiencing problems.

Others may know differently, but I'm pretty sure that will take you back to the current release.

 

No you need to restore from DFU mode.

 

Yup you need a DFU restore.

It's fairly simple: With your iPhone plugged into your computer and iTunes up and running, hold both the home button and lock button until the screen goes black, then release the lock button and keep holding the home button until you see iTunes give you a pop up stating it has detected an iPhone in recovery mode and needs to be restored. Then you can hit the restore button in iTunes and it'll even download the most up to date iOS available for your iPhone.

 

I messed up my iOS 5 beta last night. I was trying to level up in Coins vs. Zombies by changing the date on the phone. I went to far into the future and it disabled my beta, yeah, didn't think that through very well.

Anyway, I'm guessing this process won't work with iTunes 10.5 beta 7 installed eh? I'm having no luck doing a restore.

I'll just downgrade iTunes if that's the case.

 

You cannot easily downtrade iTunes. Your itunes library has been converted to a new format and cannot be read my previous versions anymore.

 

I don't keep any media in my iTunes library. Crazy, I know!

You could just restore iOS 5b7 back onto it. Maybe do it in DFU mode just to be sure, but it should work fine.

 

Tried that first, got error 1604. Then I downgraded iTunes, let iTunes download the latest release of iOS and I'm still getting error 1604. Then I found a link that said uninstall iTunes, do a fresh install, reboot the machine, remove iPhone SIM and put in DFU mode. I still get error 1604...googling for other solutions to try.

 

Try putting the phone into DFU mode and then option restore with 4.3.5 or 4.3.3 w/e you want.

And as for the iTunes dilemma, if you want to uninstall iTunes type in
sudo rm -fdr /Applications/iTunes.app into terminal and it will remove it.

But if you download the current release of the official iTunes then you will lose your current (10.5beta) library cause the "iTunes library.itl" will not be found.

Then (you wont have all your current stuff, since you're removing the iTunes library.itl) you will then have to remove a few files from the iTunes folder, it gets complicated, just follow this;

Hope I helped a little, and you can get back to all the non beta versions of things.

 

Forgot to mention, I'm on WinDURRs. I've pretty much done the equivalent of that though. Still no dice. So I'll install the latest iTunes beta again and try the latest firmware. If that doesn't work, I'll try another PC tonight. I did a fresh install of Windows 7 at home a couple weeks ago and doesn't have any version of iTunes, that will ensure I don't have existing conflicting data.

Thanks!

 

Latest beta iTunes and iOS seems to work. I had beta 7 on the device and tried to load beta 5 since that's all I had downloaded. That didn't work. New install of iTunes beta 7 and iOS beta 7 seems to be the sweet combination for me. Not sure why latest release of iTunes and iOS wasn't working for me, could be leftover files from the old beta 7 I had installed, not sure. But appears everything is OK now.
