Jailbreak iOS 4.3.5 with RedSn0w [iPhone 4, 3GS, iPad, iPod Touch] - iPhoneHeat

Jailbreak iOS 4.3.5 with RedSn0w [iPhone 4, 3GS, iPad, iPod Touch]

RedSn0w can jailbreak the latest iOS 4.3.5 firmware on iPhone 4, iPhone 3GS, iPad and iPod Touch 4G/ 3G. These are the steps to jailbreak iOS 4.3.5 with RedSn0w on iPhone 4, iPhone 3GS, iPad 1 and iPod Touch 4G/3G.

jailbreak ios 4.3.5 redsn0w


  • RedSn0w 0.9.8 beta provides tethered jailbreak for iOS 4.3.5. For those unfamiliar, a tethered jailbreak means you will have to connect your iDevice to a computer, every time you reboot, in order to boot it into jailbreak state. (Tether boot instructions can be found below)
  • If you want to keep your untethered jailbreak you better stay at iOS 4.3.3 and avoid iOS 4.3.4 or 4.3.5.
  • If you depend on UltraSn0w unlock, avoid Redsn0w, or the stock iOS 4.3.5 firmware.
  • iPad 2 is obviously not supported.

MusclerNerd of the Dev-Team also confirms that RedSn0w can jailbreak iOS 4.3.5: “@zaone @m1ckey29 ah ok thanks for checking! So those who really do want tethered 4.3.5 can use redsn0w pointed at 4.3.4 (except iPad2)”

How to Jailbreak iOS 4.3.5 with RedSn0w [Tethered]

Step 1

Step 2

Make sure iTunes 10.4 is installed. Restore iOS 4.3.4 on your iPhone 4, iPhone 3GS, iPad or iPod Touch 4G/3G and keep it connected to your computer via USB.
***You can skip this step if you’re already running iOS 4.3.5.

Step 3

Execute the Redsn0w. Hit the Browse button and select iOS 4.3.4 firmware (Not iOS 4.3.5). RedSn0w will recognize your IPSW file. Then hit Next.

Step 5

Now check mark “Install Cydia” and hit Next.

Step 6

Now make sure your iPhone, iPad or iPod Touch is turned OFF and Plugged in to your computer (Read RedSn0w instructions). Hit Next.

Step 7

Now you’ll be instructed to put your iDevice into DFU Mode. Follow the on screen instructions.

  • Hold Down The Power (Corner) button for 3 Seconds
  • Without releasing the Power button, also hold down the Home (Bottom Center) button for 10 seconds
  • Without releasing the Home button, release the Power button BUT KEEP holding the Home button for 15 seconds

Once you’ve successfully entered into DFU mode, RedSn0w will start jailbreaking iPhone 4, 3GS, iPad, iPod Touch 4G, 3G on iOS 4.3.5 tethered. When done, your iPhone, iPod Touch or iPad will be jailbroken tethered on iOS 4.3.5.

How to Tether Boot

Each time you reboot/restart/turn off your iDevice you will have to connect it to a computer in order to boot it into jailbreak state. In order to do that:

Open Redsn0w, provide it the IPSW file and choose the option Just boot tethered right now (uncheck all other options) and proceed. You will have to do this every time your device reboots or loses power.

Always Great Support for iPhone, Thanks iPhoneHeat.

erkkiboy83 August 7, 2011, 2:42 am

when trying to downgrade using custom ipsw’s apple refuses the restore with various error messages depending on editor. i have an iphone 3gs which i got from a friend 2 days ago, it was running 4.3.4 unlocked and jailbreaked. When we were going to wipe his info itunes also upgraded to 4.3.5 and baseband: 05.16.02-6.4_M3S2. I have tried like a maniac to jailbreak, unlock and/or downgrade in various orders, but absolutely nothing has worked, i cant activate the phone either, and dont know which carrier it originally was locked to. ive used sn0wbreeze 2.7.3, redsn0w,tinyumbrella, iphone explorer etc etc. best shot got me unable to boot. suggestions?

findnemo August 9, 2011, 7:10 am

Itunes does not recognize the phone at all after I install Appsync 4.0 to install app.

zustiizth August 29, 2011, 8:55 pm

Use Redsn0w 0.9.8b4 but interestingly, use windows xp.
don’t use windows 7
but restore it with 4.3.5 and jailbreak with 4.3.4
but above all,…
follow redsn0w instruction carefully!!!!!

zustiizth August 29, 2011, 9:00 pm

Make Sure The Apps Are In IPA Format And Maybe They Must Be Cracks Apps. Go To Filestube.com And Search For Apps By Putting .IPA At The End Of The File Or Games Name.
Good LUCK!!!!

it does not work,the jailbreaking process is succesful but when try to open cydia it return to the menu screen

Ronald August 17, 2011, 11:45 pm

think you gotta use redsnow one more time, but just select ‘reboot tethered’. Then you will be able to open zydia (i believe..)

nuder August 21, 2011, 3:01 am

not working

dichdo11 October 9, 2011, 7:31 am

Try to reinstall Cyndia with Redsn0w 0.9.8b4 ( last version ). I had the same problem when installed Cydia with Redsn0w 0.9.8b3, then reinstalled with Redsn0w 0.9.8b4, it works very well .

mark August 18, 2011, 3:15 pm

i tryed, but each time it starts, then freezes at the first stage, and then itunes opens. even had it restore my iphone 1 time.

nuder August 21, 2011, 2:47 am

Whiplash August 22, 2011, 11:53 pm

If I do this Jailbreak and restart my phone, do I have to plug it in my pc to use the iphone? or can it restart in a non-jailbreak mode???

nevermined August 31, 2011, 3:09 am

dichdo11 October 9, 2011, 7:41 am

My phone does NOT restart by itself after jailbroken, it freezes at the apple’s picture for hours !!! First I thought my phone was broken, but tried to restart with connect to PC( running RedSnOW, select “just boot..”), it starts again very well.

john August 25, 2011, 8:59 am

Tina August 30, 2011, 3:50 am

When I am tether booting, should I use the 4.3.5 or 4.3.4 IPSW file?

Sigit September 3, 2011, 4:06 am

Pick up ipsw 4.3.4

dichdo11 October 9, 2011, 7:34 am

depend on the IOS of your iphone, make sure they are matched.

Omaid September 3, 2011, 1:43 pm

Hi, I am sort of new to iOS and i am currently using 3gs on 3.1.3
Its not factory unlocked i believe its jailbroken, Is it ok if I upgrade it to iOS 4.3.5? and jailbreak it using redsnow?
And do i have to be connected to the internet while upgrading and jailbreaking?

Sigit September 6, 2011, 8:18 am

In my opinion,stay away from 4.3.5..
Do not upgrade ur idevice..

Omaid September 7, 2011, 8:42 am

Should i just not update it or is it ok if i move to 4.3.3
I updated it to 4.1 though works good.

Sigit September 7, 2011, 8:50 am

If u want to unlocked ur device stay away from 4.3.5,.. 4.3.3 it’s oke,because it can untheter jailbreak,but for ios 4.3.5 only theter jailbreak right now.
I suggest you to do not update..

Sigit September 7, 2011, 8:51 am

If u wanted to unlock it,stay on 4.1..

zustiizth September 7, 2011, 1:23 pm

dhawell September 24, 2011, 4:38 am

hi guys. i need help. i successfully JB my ipad 1 and it was working fine. my Ibook and twitter apps keep on crashing…so i thought all it need is a soft reset, forgot that i need to do it with Redsnow..and now it wont turn on. all i see is the Apple logo in the black background… and my pc is not recognizing the ipad. what to do? thanks

dichdo11 October 10, 2011, 9:08 pm

Your ipad just could NOT reboot itself after the TETHERED jailbroken. Try to reboot it by connecting to PC ( or Mac ), running RedSnOw again, and selecting ” Just boot tethered ..”. Good luck.

Junior September 24, 2011, 8:05 am

My wife updated to 4.3.5. How to I remove and an older, so I can tether?

Junior September 24, 2011, 8:08 am

Remove it and get an older one, can it be done, I just need to tether.

dichdo11 October 10, 2011, 9:12 pm

Might try to “Restore” through iTune to get back to as it was from the store.

I bought this white iPhone 4. running IOS 4.3.5 and the baseband is 4.10.01 which I have unlocked with the gevey ultra sim, question is how can I find out what IOS was on it so I downgrade and use 4.3.3 or 3.2. I have all my repos where I had face time and everything with a black iPhone with the same baseband and I downgrade to 4.2.1 and it work flawlessly. I know the white iPhone came installed with IOS 4.3.x not sure if it was 4.3.5 do any suggestions on figuring this out

LawrenceM11 January 29, 2012, 12:41 am

I have the white iphone 4g and when i use redsnow to try and jailbreak it, once i get to the waiting on reboot screen it reboots my iphone but then doesnt continue with the program? any ideas? i just did my girlfriends black iphone and it worked fine.
