How to Jailbreak Your iPhone 4 Using RedSn0w (Mac) [4.3.3]
Comments

will i have to backup my phone first? or the data will remain after the jailbreak? thanks very much.

RedSnow saved my bricked iPhone 4. Thank you guys!

is 4.3.3 stable? will it still cause battery drainage? thanks!

Hey. I really need help from experts. I bought an Iphone 4 which was used on AT&T and now I want to use it with another carrier. It has 4.1.0 software and 2.10.04 version. The question is: Is it possible to unlock (redsnow) my phone jailbreaking it to 4.3.3 using the custom file of this tutorial. Thank you very much in advance.

There is no .ipsw file to download... there is a 600+MB .zip file with no .ipsw files on it... Redsnow wont recognize any of those .... =/

Hello! I run version 4.1 with baseband version 02.10.04. I saved with TinyUmbrella my SHSH. I tried to jailbreak using pwnage tool (mac) 4.3.3 but it didn't work. When I finish DFU mode with sucess and I try to restore Itunes with iPhone3,1_4.3.3_8J2_Custom_Restore.ipsw there is massage in Itunes This device isn't eligible for the requested build. Please someone can help me?

I have current 4.3.3 firmware on my iPhone 4. Do I need to perform the restore step with the .ipsw files or can I simply move straight to a jailbreak with redsn0w_mac_0.9.6rc15?

What is the point of listing a new jailbreak and including comments that dont relate to it inn terms of currentness? I mean it came out last night and we have comments going back through several months. It makes no sense and now I have no signal after jailbreaking with pwnage, and im factory unlocked, then I jailbroke with rednsow and it didnt help, now I am factory restoring and will try again. This site used to actually care about the info it provided. Now it seems really sloppy like noone cares what the tutorials say. Sad state of affairs as one hacker after the other get high paying jobs with Apple to stop their work.

do I need to make step two if I'm already on 4.3.3?

Is it an untethered jailbreak?

Mine won't jailbreak. I run version 4.3.2, updated using the method explained above. I do not really care for unlock at this moment. I run baseband version 02.10.04. Right now, besides the faulty signal strength indicator (never show anything but 1 bar) everything runs fine on my phone. Once I try to run RedSn0w, it gives me an unexpected error. If I put it in DFU mode manually before running the tool, it says it's pushing limerain to the phone, then give me an unexpected error again. What is wrong? Anyone else running in the same error? thanks for any tips.

Dude, I have the exact same problem except I'm iOS 4.3.3. Really need some help ASAP. Please and thanx.

Anyone else cannot restore 4.3.2 on their phone? I'm trying to upgrade from 4.2.1 to 4.3.2 even if I try full restore from iTunes, or custom restore, or DFU, I always get a damn error 1013. Any ideas?

I have the same problem.. What do we do? Someone help..

The weird part, is even damn tinyumbrella fix does not work, nor a full iTunes restore. Scary... I'm tempted to call apple care at this point, could they know the phone was jailbroken before? The phone won't even boot!!!

check this out, it'll fix ya right up

Thanks Daniel, much appreciated. Unfortunately, my host file is backed up, and no entry to apple (I hate when software force name resolution). That didn't do it. To add a twist to the story, I have 2 iPhones. I plugged my older iPhone, and iTuns still complained that a phone in restore mode was connected! iTunes actually displayed 2 phones connected to my dismay. Something is definitely going on. Ghost connection? New Apple "security feature" ?

after jailbreaking i still have the no signal cosmetic issue, but afiter i install the ultrasn0w fix, my mms stopped working. Any fix for the fix lol?

I tried restoring with the IPSW file and it keeps telling me iPhone could not be restored. tried restoring with iTunes and I get the same message. Now my phone is on restore mood and I can't get out of it.

* Open Finder * Hold down COMMAND + SHIFT keys and press ‘G’ * Enter “/private/etc/” in the field and press “Go” * Find “hosts” file in the directory * Drag the file to your desktop * Open it in text editor * Remove the line that has gs.apple.com entirely or put a # at the beginning of it to comment it out * Save the file * Drag it back to the /private/etc/ folder. * You’d need to enter your username and password to authenticate the move

Loi, I got all the way up to remove gs.apple.com and it does not allow me to save it. It gives me the following message. To view or change permissions, select the item in the Finder and choose File > Get Info. I chose info and changed the permissions but it still does not allow me to save the file. Any ideas. Thanks

After doing the JB I now have No Service, I have gone back to stock for now. Does anyone know why the JB works perfectly on some devices and not others?

I seemed to have fixed my own issue. Restored back to stock. Turned off sim pin and activated phone on Itunes. Then did Redsnow JB and restored last backup(Itunes sync) and now all working!

I can't get the IPSW to work at all. RedSn0w isn't recognizing it one bit.

I've done the jailbreak, but cannot get cellular network, I've already restore from my backup and still does not have the network ATT

The WiFi issues are still there... and by issues i mean WiFi doesn't work

Does anyone know if this will work for the Verizon iPhone (version 4.2.7)? If not, any news when a jailbreak will be released for it?

does the 4.3.2 updates ur baseband ? I am on 4.10.0 right now.. Not like I care I am on att . Thank you DEV TEAM you are awesome... You guys are making a=our devices worth having them,I just can't imagine an Iphone without a jailbreak,Its useless. Thank you

Is there a way - if my iPhone has already been jailbroken - to just upgrade to the next version or does the JB process have to be done each time? Thanks. You guys do great work.

yes you need each time when u update to next ver.

I was able to get the jailbreak to work and restore from a backup of my phone previously jailbroken with 4.2.1: Back up/sync phone with iTunes Then follow the instructions of restoring the phone using the .ipsw you downloaded, run redsn0w Once all is complete and cydia is on the phone Open iTunes and restore from backup Pretty soon all of your settings will be restored and with a sync everything will be back to normal including cydia and 4.3.1

Could someone please address these questions: 1. I've already updated my iPhone4 to 4.3.1 via iTunes. Is there anyway to apply the jailbreak and still keep all my apps and settings? 2. If I've already updated my iPhone4 to 4.3.1 via iTunes, can I skip the restore in the first part of this walkthrough and just run RedSn0w? Would this allow me to keep the apps and settings already on my iPhone4? 3. If so, when navigating to my current firmware version, do I need to point to the one iTunes downloaded or can I just point to the one I downloaded via this walkthrough and placed in the Pwnage folder on my desktop? 4. If I have to first restore to the downloaded firmware (placed in the Pwnage folder on my desktop) before running RedSn0w, I would imagine I'll wind up with a completely clean device. If so, after the jailbreak, could I then restore from my most recent backup to restore my apps and settings or would that wipe out my jailbreak? Thanks!

Hi. Does this jailbreak work with 4.3.1 and firmware 4.10.01?

Great Job and many thanks!!!

hello! got a new iphone 4g out of the box and i followed the instructions on how to update it to 4.3.1 without updating its baseband described here: https://www.iclarified.com/entry/comments.php?enid=13789 i got that straight but i guess i still need to jailbreak and unlock it. can anyone assist me with some step by step hints on how to jailbreak and then unlock it? would be awesome! right now it says the 'insert a valid sim card without sim pin' thing when i switch it on.. thanks in advance..

Thanks, Dev-Team. You guys are the best

For everyone getting no cellular signal, after the restore you need to start itunes. If it says anything unless for you to run the backup file just reconnect the iphone. After that, the carrier signal should already be available. Then, you do the JB.

VERY IMPORTANT, after restore and before jailbreak, connect to itunes and wait to get cellular signal from your carrier, otherwise you won't get cellular signal back

My Firmware is 4.2.1 Modem Firmware is 02.10.04 on iPhone 4. Can I use this without TinyUmbrella? To protect my boot loaders?

Dear DV thnx for the JB, everything is working so perfect, no wifi issue no signals issue, even cydia is pretty fast....thnx everyone

restore back to stock, then upgrade to 4.3.1, then run redsnow? Or just restore to stock?

I followed the steps and currently on FW 4.3.1 however i am only getting one signal bar. Any suggestions how to fix it?

The same with me! Any ideas?

same here??????

If I normally sync to my desktop, and want to jailbreak using my laptop but backup the device using my laptop, what info will I lose/keep? I guess I'm asking what is contained in a backup, and will this process completely wipe the device? Being hungover literally makes me dumber, i feel like i could of figured this out if I didn't have my bachelor party this past weekend.

Works great. Installed Rock, to fix SSH password, but Rock crashes, even after rebooting. Ideas?

Follow the instructions on the Cydia home screen and do it through terminal on your Mac.

My iPad 1 (3G) is already jailbroken with 4.2.1... I have NOT updated to 4.3 or 4.3.1... I followed the instructions and am back on my normal mode of operation, but the "About" screen still says "4.2.1(8C148)"... Do I need to update my device to 4.3.1 in iTunes before doing the jailbreak? This part is unclear (i.e. what version should your device be at when using these instructions?) Cheers.

yes, you have to upgrade.

The instructions are pretty clear that don't update to 4.3.1 if you need an unlock. What if I don't need an unlock, can I just update 4.3.1 normally from iTunes and run redsn0w after that?

Well you'll still need the .IPSW file for RedSn0w to jailbreak it. You can either play it safe and like it says but if somwhow the firmware file you get from iTunes is different from the .IPSW you load in RedSn0w then I have no idea what may happen.

off course you can update, then use redsn0w. Remember that you will use .ipsw fw.

Ok, to clarify for an idiot: I'm at 4.2.1. I need to update to 4.3.1 in iTunes, then run this procedure. I just let iTunes update by itself, correct? Am I supposed to point iTunes to some specific FW file when it updates other than the one it downloads automatically. When I tried to JB on 4.2.1, the FW file I downloaded via the instructions was not recognized / valid. I want to make sure I do it right this time. thanks

I am already on 4.3.1, and ready to run redsnow, will I have to re-install all my apps/music/movies, or will they stay in place. Thanks!!

If you perform a full back-up prior to jailbreaking and afterwards restore from that backup everything should be there. That's how it worked for me. Even all my sms messages synced back.

I am looking to j/b my phone, without having to restore, like i did with greenpoison. I am wondering if the redsnow, will j/b the phone, and just add cydia to it. I dont want to have to restore it. is that possible, or will redsnow, wipe the phone back? and if i restore a phone, wont that just wipe the j/b?

I'm not sure of the methods used with greenpoison but with this one you do need to restore and after the jailbreak Cydia will be there. After you restore from your back-up then everything should be the same as before. Also if you go to Cydia and download pkgbackup and backup with it you'll be able to restore all your Cydia apps, settings, and tweaks back to how they currently are. I've already got the Mobileme lockstyle working on my phone. Also if you have wifisync make sure it's unistalled from your computer first.

I can't seem to get cellular signal after upgrading using this method. Is there something I need to install via Cydia? Thanks

I had the same worry but after restoring from my backup I regained cell servicee and everything is ok now.

I have the same, no signal. Now restoring from backup, hope it also helps for my iphone! Michael C, did it work for you?

Doesn't seem to be working after a restore from backup.. What process did you go through?

i received the message "No Service" with this jailbreak. i'm now using the PwnageTool cause i guess the issue is for the Hacktivate.

I just tried PwnageTool (was previously using Redsn0w) and still can't get cell signal... Any help would be greatly appreciated!

Finally got this working via the PwnageTool method.

Hoe did you managed this?

Use Firefox to download the 4.3.1 file and it works fine with redsnow.

will give it a try. i used google chrome... i will now use firefox

I have had this problem with multiple jailbreaks. If you restore your phone, make sure you activate it before you jailbreak. You don't need to restore it, just activate it. Then you should be good to go.

Ok I was jb on 4.0.1 and followed this guide but my phone has been stuck at 99% restoring in iTunes and about 60% on my iPhone. Should I continue to wait? It's been about 20 minutes so far with no progress.

Same problem here, could you figure out what it was or did you just wait?

Yeah I found it after searching in a old thread. I had wifisync installed well this problem happens when it's installed on the computer. It needs to be uninstalled from the computer and the computer restarted. I was getting a 1611 error in iTunes after uninstalling wifisync. I went in and found a file on my Mac called etc/host I forget off hand exactly where but I deleted a "gs.apple.com" entry in the host file and saved it back to my Mac. I rebooted my Mac and it all worked fine from there on.

Just re-install iTunes on your Mac.

thanks a lot for your instructions! I deinstalled WifiSync and found the hosts file, but I don't se the line gs.apple.com. Here is my file content: ## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost Do you remember where it showed you that line? thanks a lot again...

I read of people saying to re-install iTunes but I didn't want to risk that at all. If you open terminal and type in $ sudo nano /private/etc/hosts it should take you there but I don't think that worked for me so I ended up figuring out a different way to navigate there.

It worked now. I updated my MacOS and now it worked fine. Thanks for your help!

No problem. I'm still trying to remember the other way I navigated to that file but regardless we both seem to have it figured out. While I was searching for the other way I got there I came across some stuff which says that particular line redirects requests for certificates for authenticity that iTunes will make to the Saurik server. I guess that needs to be deleted so that the jailbreak can create a fresh one. I have no idea.
