Here is the revised downgrade procedure from 9.1 beta to 9.0 GM:
No restore necessary - just option click "Check for Update"
.

The Web site for iOS 9 GM is:
http://www.redmondpie.com/ios-9-download-links-for-iphone-ipad-ipod-touch-ipsw-links/


Sequence:
  • Download iOS 9 GM for your device (see links above)
  • on your device - iCloud disable Find my iphone/pad -- OPTIONAL to be safe should something go wrong
  • delete iOS Beta Profile and reboot
  • connect device via USB
  • Then goto iTunes - option click " check for update"
  • point to downloaded firmware file and install
  • check software update on iOS device - should say you are on latest version

tested with iPhone 6 and iPad Air
This works just fine as well. Something I found interesting while using these steps on another device earlier: ALL of my content, including Touch ID, Wallet cards and HealthKit info was restored just fine. So this is a quick and easy way to do it. I personally prefer to backup and restore...am sure it makes no difference, just makes me feel better.

Wow! 5 pages for what you would think was a simple question!

FWIW, I had no problems going from 9.1 to the 'new' 9.0 within 10minutes, doing a simple backup and restore. ymmv, but these were my steps.

From 9.1:
1. Remove the beta profile
2. Backup to iTunes and then archive the backup under preferences>device.
3. DFU
4. Plugin and restore with the latest version of iTunes, which will automatically load 9.0
5. Restore from your backup (there should only be one now listed with the latest version of iTunes)

Restore conpleted in about 15minutes


In case you did not read: some people don't have a backup or are afraid that a 9.1 beta backup does not load!

Therefore the method described in my post #117 - without RESTORE necessary!!

Right...like I said, that works just fine as well.

did you downgrade with DFU or just the method I described in post#117?


I did not use post #117

I just used itunes and dfu mode and genuine cable up to date itunes in yosemite.

I was warned that it may result in a restore rather than upgrade. I went for it feeling confident.

If #117 is 100% no backup needed, tried and tested, then perhaps your option is the one to go with.

Apple should have never allowed regular customers who are not developers and might not know what they're getting into to download betas, I hear they're lots of people now finding out they've pretty much screwed there phones until a 9.1 final version is released to fix this
I am sorry to disagree. I am not a develoiper, but I have had extensive experience beta testing software and operating systems, going back to Windows 3.0. I enjoyed the experience and I am glad I was able to be a public beta tester.
By the way, 9.1 isrunning well on both my iPhone 6 and Ipad Air 2.

Do you use the iOs device in the USA or outside? I believe the News app is currently US only.

I live in the UK, I did have the news app on 9.1 and found it quite good.

I didn't realise it was USA only the news I was getting was UK based.

cheers

To be safe I might do this on iPad first. Not too bothered setting that up as new if it all goes wrong.

Re the Newx app, yeah that's US only in 9.0

Sidenote: is there anything that would stop me registering the 6S with the beta program then restore a current 9.1 backup? I'm sure I read somewhere that Apple sometimes block new devices from beta software for a while

Any official comparisons of the 9.0 public release to 9.1 beta? I'm disappointed that the majority of issues I had with PB3 weren't fixed in the final. I may go to 9.1 beta to see if it helps.

They don't block new devices. If you're referring to the newest iPod Touch, that couldn't get beta because it was released inbetween beta builds. The build that came out the following week had support.

iOS 9.1 beta 2 should be coming out the same week as the new iPhones of builds follow the usual two week cycle. I'd imagine it will have support for 6s and 6s+. (If 9.1 beta 1 doesn't already)

Downgraded iPhone 6 and iPad Air from 9.1 beta to 9.0 GM

So far no problems at all on either device. No restore necessary - just option click "Check for Update".

The Web site for iOS 9 GM is:
http://www.redmondpie.com/ios-9-download-links-for-iphone-ipad-ipod-touch-ipsw-links/


Sequence:
  • Download iOS 9 GM for your device (see links above)
  • on your device - iCloud disable Find my iphone/pad
  • connect device via USB
  • Then goto iTunes - option click " check for update"
  • point to downloaded firmware file and install
  • after install delete iOS Beta Profile and reboot
  • check software update on iOS device - should say you are on latest version
This worked perfectly for me on iPad Air 2

I tried it and went from 9.1 to 9.0 with no problems at all. Is this a new thing? I thought everyone said that reverting back would require 100% you to have a previous 9.0 backup.

iPhone 6 went down to 9.0 as effortlessly as updating upwards. Nothing required at all except downloading the .ipsw and option clicking update.

I was running the 9.1 public beta. I had a 9.1 iCloud backup and an 8.4 archived backup on iTunes.

I deleted the public beta profile on my phone and then restarted it. Still showed that I was running 9.1.

I then put my phone into recovery mode when plugging into the newest version of iTunes (released today).

iTunes automatically restored the phone and everything was exactly as it was before I put it into recovery mode. It seemed to restore from my 9.1 iCloud backup...and it shows that I'm running iOS 9.0.

I'm thrilled.

I have been struggling with this issue for the last week, finally coming to the conclusion that I'd have to setup my 6s plus from scratch. After reading your post I decided to try what you did. Now I'm thrilled too that I'll have a nice clean 9.0 backup ready to restore on my new phone next week. :)

So you download that ipsw file and option click an update to get from public beta 9.1? Can I get another link then please. Sorry for the hassle, I'm just skeptical about iOS 9.1. I need a comparison between public beta 9.1 and General release 9.0.

I was researching this issue online since I am upgrading from an iPhone 6 which was running iOS 9.1 to an iPhone 6s and wanted a clean install from backup. This forum post was the top trend on Twitter for iOS 9 and I absorbed much of the info. I'd like to share my experience as I believe it will help everyone trying to go from 9.1 beta to 9.0 general release.
First, I plugged my iPhone (in recovery mode) into my computer running iTunes 12.3. It recognized the phone and prompted me to update or restore. I chose update. It gave me a scary message warning that a restore may be necessary if the update fails. I proceeded anyway, knowing I could go back to the beta with my backup if it failed. It went through the process, took about ten minutes, and updated! I am now on the 9.0 general release (13A344). I did absolutely nothing to prepare as far as downloading a software profile from anywhere or even deleting my beta profile beforehand. The only issue I've encountered has been a software update showing before I deleted the profile. Now I have a badge app icon over the settings app showing an update is available, but actually entering software update shows no updates available.

In short: The way to go backwards from iOS 9.1 to 9.0 is simple. Delete the beta software profile first. Then connect to iTunes in recovery mode. Then select update. That's it. It does work and you lose no data. I'm quite pleased to be ready for a clean install on my 6s!

UPDATE: I repeated the same process with my iPad Air 2 except I deleted the beta profile first. This time, no badge app icon on Settings and no prompt to update. Running 9.0 perfectly.
