Downgrade iOS 5 beta to iOS 4.3.3
Alright so you’ve had your fun playing around with the iOS 5 beta, but you’re tired of dealing with the quirkiness and bugs related to a beta OS. Now, contrary to popular belief, you can downgrade back to iOS 4.3.3 without much effort. Unlike downgrading from other iOS versions, Apple still signs iOS 4.3.3, so you don’t need to do anything funky. For the purpose of this walkthrough, we’ll assume you’re using an iPhone.
First a few quick notes and warnings. You probably noticed when installing iOS 5 beta the warning from Apple:
“Devices updated to iOS 5 beta can not be restored to earlier versions of iOS. Devices will be able to upgrade to future beta releases and the final iOS 5 software.”
In other words, Apple says iOS 5 beta is a one way street. Apple probably issues that warning for good reason, and it’s probably wise to take their advice and not attempt downgrading for whatever unspecified reason they give. While this should have no effect on your iPhone UDID assuming you activated it with a dev license, nobody knows for sure until the next beta comes out. Be sure you have a backup of your iOS device, and as alway, we are not responsible for you screwing up your hardware so proceed at your own risk.
So you’re comfortable ignoring Apple’s advice and all those warnings and want back to 4.3.3… here’s what to do:
How to Downgrade iOS 5 Beta to iOS 4.3.3
There are actually a few methods to downgrade back down to 4.3.3 from iOS 5, but we’ll cover the easiest way. For the purpose of this walkthrough we’ll reference iOS 5 beta 1 and iTunes 10.5 beta so be sure you have that handy before getting started.
- Put your iPhone into DFU Mode: turn the iPhone off, hold down the Power and Home buttons concurrently for 10 seconds then release the power button, continue holding Home button until iTunes tells you an iPhone in recovery mode has been detected – when you get that message and the iPhone screen is black, you know you’re in DFU mode
- Remove any host file modifications that you may have made in the past (like when fixing iTunes error 3194, etc) – if you haven’t made any changes to your hosts file related to Apple’s servers, don’t worry about this
- Within iTunes, click on “Restore” from the summary tab – now you have two options, you can either attempt to restore from backup which has limited success, or just restore directly to iOS 4.3.3 IPSW
Let iTunes do its magic and you should be back to 4.3.3 without issue. You can also do this through Xcode, but this method is by far the easiest. Yes, it does work with iPhones who used the Voice Over bug to skip iOS 5 UDID activation.
Alternatively, use TinyUmbrella
If the above method doesn’t work, you can always try downgrading with the help of TinyUmbrella, but you’ll still need iTunes 10.5 beta. You can grab TinyUmbrella (direct download links: Mac or Windows). The TinyUmbrella method is basically the same as above, but you can force TinyUmbrella to handle the hosts change for you by doing the following option within the app:
- Launch TinyUmbrella and go to the “Advanced” tab
- Uncheck “Set Hosts to Cydia on Exit” – this allows you to use Apple’s servers and is the same as manually removing any Cydia hosts from your hosts file
After that’s done, you can restore the iPhone as usual through iTunes 10.5 beta.
i cant make a another copy of hosts plzz help me i beg u
its so hard help me plzz
please help! i tried to downgrade from ios 5.0 and all i get is an error that says : This device isnt eligible for the requested build. (this after connecting online with apple )
I already changed the hosts file,
Whats wrong and how can i solve it?
thanksss

Can anyone describe simple steps to a non-techie about how to revert back FROM IOS 5 to previous software on a iphone3GS? Key issue: ipod function no longer works or plays in my car after the upgrade. Also, do I need to back up the whole iphone before downgrading? Apple must fix this
They don’t warn about upgrade incompatibilities, don’t offer downgrades, and have no solutions – unacceptable.
hey, i’ve downgraded from ios5 to 4.3.3

Very great!!! its works… thanks
i have iPhone iPhone 3GS BB 16.15.00 Factory Lock Jailbreaked with redsn0w.
i m not a new to hacking iDevices.
i upgraded my iPhone 3GS from ios 4.3.3 to ios 5 beta 7.
there is no ultrasn0w released for sim unlock for ios5 thats y i downgraded back to ios 4.3.3 but now when i installed ultrasn0w, the phone does not read the sim and a text “SEARCHING” ticks in place on signals. Even i have tried other sims as well, why so? has ios 5 blocked something in my iPhone?
i even downgraded to 4.1 , 4.3, 4.3.2 and now i m on 4.3.3 but i could not unlock the sim on any of them
what is your baseband? to fix the problem, jailbreak phone with redsn0w_win_0.9.6rc15. boot up run cydia, add cydia.iphonerepairs.org to cydia repo, search for ultrasnow and install. this is only if your bb is 6.15. and your on 4.3.3 if you get this problem on ios 5.0 or 5.0.1 then search for ultrasnow fixer and install this before ultrasnow, reboot with redsnow and your done.

If i downgrade to 4.3.3, will it run with apple. I am saying this because im going to restore it from an ipsw. Will the 4.3.3 be the official apple software where if there is an official by apple, for example version 4.3.4, will it automatically detect that in the update button?
what are host file modifications?

Hey Gys please help me i am tired to get back ios 4.3.3 in my iphone 4 :( from ios 5 beta 3 ….
i have done every possible way to get my ios 4.3.3 back but every time i got failure with error 1 :( :(
(i don’t have any knowledge of shsh.)
so please give working steps for my this problem
ThanX
If u dont even understand shsh then u should not be experimenting with firmwares especially betas
I couldn’t get this to work on iOS5b3 iTunes says my phone is not able to do it or something. Frustrating!!!
yes me too,always get stuck in error 1
will it work for iOS5b3?
Yes, but you will end up on iOS 4.3.4 unless you saved SHSH blobs.

For all those who nearly threw their iPads/iDevices across the room from frustration, what worked for me was digging into the “hosts” file. Do a search for what your hosts file should look like and how you can edit it. Took me hours, but I finally got it.
Tried editing hosts in various ways… using Tiny Umbrella… even tried 4.3.4. no luck. All methods just return various errors.
Didn’t work for me. Running an iPod Touch 4G.
When I was just using iTunes, I got Error 1611.
When I was using TinyUmbrella and iTunes, I got a message reading “The iPod cannot be restored at this time… iPod software update server could n’t be contacted…”
Help?
You need to remove gs.apple.com or any similar modifications from your hosts file
There’s NOTHING in my host file.
where is your host file located?
Fixed it. Thanks.
this isnt working on my ipad 2 (wifi)
does this work if your UDID is registered?
Thanks Alot Bro Realy Helped Me Out.

@ Kyle
I posted 2 days ago but my comment is still awaiting moderation :)
I’ve done the following and all went well (I still have my pics, contacts, sms, apps …)
If you’re under iOS5
1) Backup your iPhone (right click on the iPhone in the Devices List in iTunes)
2) Click on restore and let iTunes finish the process
If your UDID is registered on a developer account, you’ll be able to downgrade without any trouble. Try to google “register my beta” and choose the first link
3) When the restore is finished, your iPhone is with 4.3.3 and you’re baseband is also downgraded.
4) iTunes now propose to configure the iPhone as a “new one” or to restore a backup. Select the backup you made at Step 1.
5) You can enjoy your downgraded phone, with all your pictures, apps, messages, contacts… :D
Hope this helps
If I activated my ups 5 by editing the system plist meaning I do not have a UDID registered device, can the method still work? I tried downgrading previously but ended up in the error 1 loop and baseband remained on iOS 5’s baseband. Any advice?
yes me too,any help ?
If I use this method, will my device get stuck in boot mode? Also, will I lose any data such as pictures and apps?
thanks , it’s work for me
This worked for me on an iPhone 4 (GSM), and iPhone 3GS, and an iPad 2 (WiFi). Thanks!
did you lose your pevious app and music content when downgrading?
did you lose your app and music content???

Thank you guys.
I just did this one my 3GS. iOS 5 is feature rich but the speed is very slow and the rate at which apps commit suicide can give somali hostages a run for their money.
1. Put iPhone in DFU
2. Shift restore with iTunes 10.5 by selecting 4.3.3 ipsw
3. ???
4. All done.
Note your iOS 5 backups will not work on the freshly restored phone. And you’ll end up losing all SMS and any other data not on iTunes.
Cheers!
will you lose your apps and your music???
only a noob would want to downgrade from a beta OS
write something useful prick
I wonder what the difficulties are. I will say that I downgraded using iTunes 10.5 and I didnt have to put my iPhone into DFU mode. Tha phone was on, running like normal and I option-restored 4.3.3. It restored fast and easy.
did you remove any host file modifications??
Hello Robert,
so you did not use dfu? Please answer fast!
P.S. What iTunes do you need? (Itunes beta 1,2,3,4,5,6?)
I am pretty sure this is device dependent. It may work on the iPhone, but I don’t think any firmware downgrades work for iPad 2, for example.
I would strongly suggest everyone heed Apple’s warning and stay on iOS 5. You shouldn’t install iOS 5 beta onto your daily device anyway, that’s what staging hardware is for.
I also downgraded the same day I first installed the beta to see if I could and there were no hiccups. It makes me wonder why Apple says it’s not supported, maybe they just don’t want to be on the hook when 4.3.3 is no longer signed due to a minor update like 4.3.4? That’s my 2 cents.
did the downgrading work for you?
I did this the other day on a 3GS after trying out the iOS5 bug thing and it went fine. Without UDID running the beta is pointless, so I’m glad it was simple to downgrade.
As far as I know my firmware never changed, but I didn’t bother to check in 5b1.
did you remove any host file modifications to downgrade?
