Aditi Thapar June 22, 2010 at 12:51 pm

Does this work with the original 2G iphone as well? :/

Shawki June 22, 2010 at 12:52 pm

I were stucked when i bought my iphone to 3.1.3 and i wasn’t able to unlock it, so I’m afraid to update it to 4.0 :S

Abhishek June 22, 2010 at 12:54 pm

No iOS doesn’t supports iphone2G

Asgar June 22, 2010 at 12:54 pm

I tested ultraslow for 3.1.3 bb 5.12.01 it’s working fine

Abhishek June 22, 2010 at 12:55 pm

@Shawki: If you’ve iPhone 3G go ahead and follow the steps mentioned above, I too have an iPhone 3G and I’ve unloacked and jailbreaked my iPhone 3G without any issue..

Abhishek June 22, 2010 at 12:56 pm

This tutorial is for iPhone 3G only..

Abhishek June 22, 2010 at 12:57 pm

@Assgar, Download the redsnw from this post..

eryk June 22, 2010 at 1:02 pm

it partially worked for me… cydia icon is all white, and it freezes after adding the repo on “downloading packages”

Saud June 22, 2010 at 1:06 pm

If somebdy have tried this please let me know the result……

Shawki June 22, 2010 at 1:06 pm

abishek, after i couldn’t unlock the iphone 3g, my cousin that live in us and i swap phones, so now i have iphone 3gs with 3.1.2, go for it and update to 4.0??

Abhishek June 22, 2010 at 1:13 pm

wait if you’ve 3GS..

Art June 22, 2010 at 1:13 pm

Does it preserve the baseband?….

And how about iPhone 3GS with old BB?!….

Abhishek June 22, 2010 at 1:15 pm

no it updates the baseband… but ultras0w works for the updated one…

Mike June 22, 2010 at 1:20 pm

Thanks for the tutorial Abhishek.

Can you confirm that ultrasn0w works with baseband 05.12.01?

Regards,

Mike June 22, 2010 at 1:21 pm

Ah, thanks Abhishek. Disregard my last post.

Bassist June 22, 2010 at 1:25 pm

You do not need to put the phone into DFU mode to do this, you can simply update via iTunes to iOS 4.0, then use redsn0w to jailbreak and unlock.

DoooooooooD June 22, 2010 at 1:37 pm

Says I cant install ultrasnow on the iPhone 3G… i have baseband 05.12.04

What gives??

Bassist June 22, 2010 at 1:37 pm

Make sure Cydia has updated, and refreshed its sources.

Good friend June 22, 2010 at 1:40 pm

Dear Abhishek,
Im on step 11 and it still says Downloading Jailbreak data why is that? Thanks

Bassist June 22, 2010 at 1:42 pm

It’s simply just that… it’s downloading the data to your phone from your computer. Give it a little bit of time and it should complete.

Good friend June 22, 2010 at 1:42 pm

10 mins now

Good friend June 22, 2010 at 1:43 pm

ok Bassist how long did it take you?

Bassist June 22, 2010 at 1:45 pm

I’ve occasionally had my phone crash whilst jailbreaking. It should be noted that you can disconnect it safely in the middle of it jailbreaking and start again from the beginning. Reboot your phone first then try again.

Good friend June 22, 2010 at 1:49 pm

ok yeah it finished but there was no jailbreak was still locked trying it once more time hopefully works

Good friend June 22, 2010 at 2:04 pm

Iphone is still locked after jailbreak

Fraucha June 22, 2010 at 2:04 pm

Following instructions, however it is locked on the waiting for reboot stage, how long should that take? This is 3GS went from 3.1.3 to 4.0, previously I was unable to unlock, but only jailbreak, something about a safeguard (encryption or hard wire) with AT&T… Hell I live in Ukraine now, I am out of my AT&T contract and just wanna use my phone lol. Anyway, it has been in “Waiting for reboot” for about 15 minutes now.

Abhishek June 22, 2010 at 2:05 pm

Cydia really takes long.. all you need to be patient… first you will see a white icon only.. once updated icon will come

Bassist June 22, 2010 at 2:13 pm

Fraucha, sounds like you have a 3GS running the new bootrom, if you were unable to unlock then, you are still unable to unlock now. Do not use the .IPSW used in this tutorial on your iPhone 3GS, it’s for 3G only.

I suspect that ‘Good friend’ may have done the same on a 3GS.

Fraucha June 22, 2010 at 2:16 pm

Okie dokie! I will give it a few hours! Hey time to waste time playing WOW.

Fraucha June 22, 2010 at 2:24 pm

I see. I hate this. I guess I will just restore and use it as an iPod until I can find a way. Thanks.

Fraucha June 22, 2010 at 2:30 pm

Had I known that I was going to have this problem, I would not have upgraded my phone to 3GS, hind site is 20/20.

Bassist June 22, 2010 at 2:32 pm

Don’t be downhearted – iPhones rarely stay secure for long, with the Dev Team and Geohotz ‘tinkering’ round the clock.

I believe Geohotz managed to unlock the iPhone 3Gs 3.1.3 running the new bootrom, but he hasn’t released anything packaged yet. I suspect that it will take no longer than a couple of weeks before your iPhone 3GS will be able to be unlocked.

Fraucha June 22, 2010 at 2:41 pm

I have patience, I have waited this long I can wait a bit longer. In the meantime I am using a Google Phone, I really dislike it, but it works with KyivStar and any other SIMM I put in. But still it is clunky and not easy to use. So, I will wait!! Thanks

Abhishek June 22, 2010 at 3:21 pm

@Fraucha Did cydia prompted for update??

moe June 22, 2010 at 3:23 pm

its not working u asshole :@

Bassist June 22, 2010 at 3:30 pm

Instead of leaving shitty comments like that, how about actually telling us why it doesn’t work. I guarantee it’s because you’re too much of a dumb prick to follow the instructions properly.

Fraucha June 22, 2010 at 3:35 pm

It actually never got past the reboot phase, so I had to restore and utilize the backup procedure to recover everything. It’s ok, I can wait until there is a firm fix for 4.0 (8A293) and firmware 05.13.04. I bought this 3GS 32gig right after the production run started, and had NO idea there would be complications, my fault for not doing proper research!! Thanks for your comments though :-D

moe June 22, 2010 at 3:40 pm

sorry about the bad comment i was pissed, the thing is. I have tried all the steps above and after that the screen just went black and now the phone is not being recognized by itunes. I don’t know what to do :( sorry again

Saud June 22, 2010 at 3:43 pm

I have updated to ios 4 and have followed all the steps after launching the cydia its jus stucking on Downloading Packages. Please Help…..

Fraucha June 22, 2010 at 3:46 pm

Moe: I myself did not take offense, I have tried many things and head many people claim they can unlock my phone, all for nought. So, if I did not realize this was not for 3GS it is my fault for not reading that there was no “S” after each G3. No biggie. I had the same problem as you and just held down the power button for about 20 seconds after I closed out and unplugged and went back through the restore process at iTunes.

moe June 22, 2010 at 3:48 pm

Fraucha: I have tried it on iphone 3G not 3Gs

Fraucha June 22, 2010 at 3:48 pm

FYI my model number is MC137LL

Aamir June 22, 2010 at 3:53 pm

is there any solution for 3gs showing no IMEI and no ICCID? Stays in recovery mode, nothing works; no red snow no nothing and even the forecast doesnot give any information on firmware, base band etc. It was on 3.1.2 5.11.07 once I could use it a month back

moe June 22, 2010 at 3:53 pm

Fraucha: 1 last thing, i am entering the DFU mode but itunes is not recognizing my phone, it is sending and error. Anything i can do here ??

Saud June 22, 2010 at 4:10 pm

I have updated to ios 4 and have followed all the steps after launching the cydia its jus stucking on Downloading Packages. Please Help….

deeqwerty June 22, 2010 at 4:14 pm

My ipod 2g (MB) is stuck at waiting for reboot for the past 15-20 mins and the screen is all dark.

Am I missing something something here?

deeqwerty June 22, 2010 at 4:16 pm

What I did was to exit itunes after I started redsnow. After that I followed everystep as indicated.
Please help.

deeqwerty June 22, 2010 at 4:24 pm

Ok, got it. I was not releasing the home button immediately after 30 seconds.

Its jailbroken now. thanks guys.

Bassist June 22, 2010 at 4:29 pm

@Saud: The Cydia servers are under an understandably high load at the moment due to the latest redsn0w release, just be patient and keep trying.

I usually wait a couple of days after release before I do it, so that the servers are back under a normal capacity.

Murali June 22, 2010 at 4:41 pm

This works Gr8. I just unlocked 2 iphone 3G.

Abhishek June 22, 2010 at 4:51 pm

Guys Here are the steps that you should follow to update cydia:
Make sure you’ve WIFI working on iPhone, You can check it by opening any site at Safari

-First launch cydia, then it will reorganize, wait for sometime.(arounf 5-7mins).

-Then if you still see the same screen then kill the cydia process( you can kill process by pressing the home button, then you will be redirected to homescreen then press home button 2times, it new tiny window will pop where you will see all the processes running in background, tap on process until you see the icon wiggling inthis case you to keep on touching cydia, then touch on the red badge, it will kill it).

-Now again launch cydia and this time it will prompt you for what king of user you are, tap on first option. i.e User.

- Now wait for sometime ( aroung 5-10mins at max).

- You will see the list of changes, if not then kill the cydia process and again launch. this time you will the changes, do the complete upgrade. again wait for say another 5-7 mins.

- Now again launch and add the ultrasn0w repo.

- Install it and after that it prompt for reboot.

- You are done..

-So far I’ve unlocked 3 iPhone 3G by this method.

danny June 22, 2010 at 4:55 pm

the firmware file i download from step 3 when i extracted them and looked through itunes to restore it doesnt recognise any files from step 3 any help

Saud June 22, 2010 at 4:56 pm

@Bassist : Thanx for the information. M trying

Saud June 22, 2010 at 5:18 pm

Its Done Thank You very much

Nelson June 22, 2010 at 5:28 pm

Finished and works like a charm :)
This is for newbies such as myself and no fancy techniques and all (i was still on os 3.0 and 04.xxxxx band). I was kind of skeptical about the beta version of redsnow but hey, all i need are making phone calls and browse .

The whole process took me 3 hours (4 if you count the downloading of the ios system file, I am in China and it runs 40k/s), I spent most of the time on updating cydia files and trying to download ultrasnow.

A few notes:
1. Although the ios4 has multi tasking now, but you should set autolock to never after running redsnow cuz you probably want to keep an eye on the process on the screen.

2. I spent a good 2 hours on deal with “host unreachable” error in cydia( for both cydia update and downloading ultrasnow) and eventually solved the issue by setting proxy of my wifi connect to 119.70.40.101, port 8080 (there is a state firewall in china blocking youtube and facebook, guess thats the reason but i had the same problem with cydia when i was on 3.0, but rock and icy did not have the same issue).

3. I did not try this time but when i was updating to 3.0 from 2.xx, i tried many times and failed. turned out i had the sim card in the phone while i was jailbreaking and unlocking. this time i took out the sim card after i updated to 4.0 before all the jb and unlocking process, and after i installed ultrasnow(which automatically reboot), i insert the sim card and boom, 4.0 baby!

good luck to you all!

3.

Razi June 22, 2010 at 5:54 pm

Hey Abhi, thanks for that beautiful tutorial.

Just one thing, Step 4 is a bit confusing. The instructions you wrote are for Recovery Mode (Holding Home Button and then plugging iPhone to PC), may be i m wrong.

Thanks again for this great tutorial :)

Michael June 22, 2010 at 6:06 pm

Hey guys i have one question. Do this work and unlock my baseband from 3.1.3 and can i use my phone again ?

Cheeky June 22, 2010 at 7:08 pm

AWWWWESSSOOOOMMMMMEEE!!!! Thanks sooo much guys – been waiting months for this. :-)

Albert June 22, 2010 at 8:01 pm

One question the cybian is been saying Downloading packages for about 15 minutes is that ok?

Carrera June 22, 2010 at 8:32 pm

@ Nelson:
Thanks for your information. That’s nice!!! :)

scott June 22, 2010 at 9:39 pm

Tried this on my iphone 3g 5.13.04, got stuck at a black screen while redsnow was waiting for reboot, i held down the power and home button for like 20 seconds and it started back up, nothing deleted and no changes. Was that the reboot it was waiting for, and i just timed it perfectly?

oscar June 22, 2010 at 10:36 pm

how do i replace the repo?
or do i need to?

what is it?

shawn June 22, 2010 at 10:57 pm

i have 3gs upgraded to 4.0 can i unlock and jailbreak this

i had downloaded redsnow 0.9.5b53 also i ahave downloaded ipsw restore for 4.0 it says incorrect ipsw

Prajath June 22, 2010 at 11:18 pm

Wow wow I had jailbreak and unlocked from your opinion. Iphone 3g 4.0 Baseband 05.13.04 Thank you very much.

Bassist June 22, 2010 at 11:28 pm

@shawn, no you cannot unlock your iPhone 3Gs using this tutorial. You need an iPhone 3Gs with a model number that does NOT start with ‘MC’ and the correct .IPSW file. The IPSW above is for iPhone 3G ONLY.

Abhishek June 23, 2010 at 12:26 am

Ok i found why cydia is behaving weird !! There is a problem with modmyi repo, jst go to repositories>modmyi & remove it.. After that cydia will become stable and i belive you dont need to follow the long steps that i mentioned earlier… Lemme know if you face any further issues….

Abhishek June 23, 2010 at 12:29 am

You can reinstall modmyi repo later on, once it becomes stable…

Danny June 23, 2010 at 1:12 am

I’m downloading the zip file in step 3 when I extract it there is no .ipsw file there can anybody help me please

arjun June 23, 2010 at 2:10 am

hey!!…i just cant download ultrasnow…just wen i press install..it says no nodename nd all..wat to do???

habib June 23, 2010 at 2:26 am

yessssssssssss it worked for me.
i did my 3gs 32gb version 3.1.3 baseband 05.12.01.
just did straight from my old cydia and went:SOURCES and intalled repo666.ultrasn0w.com
very easy like drinking water . took less than 30 second

sanit June 23, 2010 at 2:39 am

THIS REALLY WORKS THANKS….

Dave June 23, 2010 at 3:16 am

to all having trouble with the reboot. i was having the same issue when i stopped itunes from starting up all went well

scott June 23, 2010 at 3:42 am

Just got this to work for me, at first the wifi did not work after my first jailbreak, but after taking out my SIM card it worked after another jailbreak

sanit June 23, 2010 at 5:38 am

sanit June 23, 2010 at 6:19 am

never mind I got installed now

shmelly June 23, 2010 at 8:22 am

The jailbreak (with redsn0w) & unlock (with Cydia/Ultrasn0w 93) worked for my iPhone 3G iOS4 5.13.04. It picks up the T-Mobile network and I am able to make/receive calls, however, it says I do not have any cellular data service (I have it on my plan). How can I fix this? Thanks in advance for the help.

GSMCRACH June 23, 2010 at 10:09 am

Danny,
Just rename *.zip to *.ipsw

yossi June 23, 2010 at 2:52 pm

WARNING! WARNING! WARNING!
This jailbreak indeed works great – but it will leave your iBooks app unusable – use with caution!

Bassist June 23, 2010 at 3:23 pm

@shmelly, you will probably need to re-enter your data network details: From the main screen of your iPhone, tap Settings > General > Network. Tap ‘Cellular Data Network’. Then re-enter the correct data here.

I don’t know the settings for T-Mobile but I’m sure you can Google for them or even call them.

Geert June 23, 2010 at 3:37 pm

All went well until Step 11. After the reboot the iPhone doesn’t seem to have activated the Sim card yet (only 1 signal strength bar and no network operator icon), not sure if this is normal? I also have a completely white Cydia icon? I don’t have wifi here so I will have to wait until I get home to see if Cydia can connect to the Internet using wifi.

Nemesis June 23, 2010 at 3:37 pm

I followed instructions to the tee, but when running Redsn0w I got an memory access error . Solution lay in disabled DEP (Right Click My Computer, Properties, Advanced TAB, Performance Button, Data Execution Prevention TAB, “Turn on DEP for essential…” or add “redsn0w.exe” to be excluded while keeping radio button “Turn on DEP for all programs…”

Bassist June 23, 2010 at 4:20 pm

@Geert: Your phone is Jailbroken but not unlocked yet. You need to use ultrasnow 0.93 on Cydia to unlock the phone.

As for the icon appearing white, follow this guide.

Abhishek June 23, 2010 at 9:35 pm

Post is updated, We’ve provided new redsn0w links..

DK June 24, 2010 at 1:20 am

@Nelson

This seemed to work for me too! Also living in China… I had tried many proxy servers to no avail, why does this one seem to work?

Shawki June 24, 2010 at 3:19 am

should i go for it on my iphone 3gS!!!??

Good friend June 24, 2010 at 6:31 am

What do i do (it finally jailbroke but..) cydia is white icon please give me step by step instruction how to fix Thankzz.. Anyone??

Good friend June 24, 2010 at 6:46 am

What do i do (it finally jailbroke but..) cydia is white icon please give me step by step instruction how to fix Thankzz.. Anyone?????

Good friend June 24, 2010 at 6:46 am

What do i do (it finally jailbroke but..) cydia is white icon please give me step by step instruction how to fix Thankzz.. Anyone?

Geert June 24, 2010 at 11:59 am

@Bassist: Thanks that worked perfectly! My 3G phone so far works perfectly with iOS 4.0.

@Good friend: have a look at the reply Bassist posted to the exact same question I had.

@Shawki: No! I assumed after a fairly smooth upgrade of my 3G that it would work just as well for my 3GS but alas ;(

Geert June 24, 2010 at 12:02 pm

I am looking at how I can either jailbreak and unlock my 3GS on iOS 4.0 (preferred option) or downgrade back to 3.1.2 so I can use it again (I tried the restore using an official 3.1.2 but I get a message saying my phone is not eligible for the downgrade!)

Geert June 24, 2010 at 2:11 pm

There may be some hope for me, I just managed to find out that I have the old bootrom (iBoot-359.3) so I guess I can still JB & Unlock my 3GS?

How do I downgrade back to 3.1.2 so I can start again and do it properly this time?

Bugoy June 24, 2010 at 2:50 pm

after jailbreak of my iphone 3G IOS4 works perfectly, however cannot unlock it as there is no wifi connection. can someone help?Am I skipping something?

Florence June 24, 2010 at 7:26 pm

Thank you very much! Like you guys, I didn’t have a network signal after running redsnow, but when i updated my cydia and add “repo666.ultrasn0w.com”, everthing was ok!!! The only problem i got is that I lost all my contacts, songs, movies, applications, messages, etc…. So if your planning on upgrading to IOS 4, better remove them all before the upgrade to speed up the process.

It takes time, but it’s worth it!

desi June 24, 2010 at 8:51 pm

Hey can someone please help me out.. I’m an idiot so i might have done something or didnt do something very obvious. I’ve upgraded to ios 4.0, jailbroken en unlocked my 3g.AND ITS AWESOME. Anyway.. it works fine.. But my internet connection only works through wifi. so basically i cant anything with my phone outside of my house except for mtexting and calls. Does anyone know what might cause this problem..

desi June 24, 2010 at 9:27 pm

ok so i know whats gong on. Normally id go to network settings and add the apn thing. But there doesnt seem to be such a thing. the entire things changed.. Where can you manually change your network settings.. Help me please

Shelly June 24, 2010 at 10:52 pm

Hey Abhishek,

Is there any unlock for Iphone 3GS 3.1.3, baseband 5.12.01?? Bootloader is 6.4. I have been trying to find something for over a few months now, and I was waiting for Dev team to launch something once OS4 came out… but I haven’t been able to find any update on 3GS 3.1.3 bootloader 6.4….

Please get back to me.

TY

Gus June 25, 2010 at 7:24 am

iPhone 3G 3.1.3 redsn0w jailbroken, ultrasn0w 0.93 unlocked. Eveything is great. I don’t want to upgrade to iOS. I still have iTunes 9.1 on my computer (Apple). Is it safe to update the iTunes to 9.2 now? Will I have to jailbrake and unlock it again?

michael June 25, 2010 at 11:32 am

I have a 3g iphone and i am doing everything it says to jailbreak the 4.o firmware but when i do it through redsnow it says that it is done but my phone is just at a black screen, it does not do anything else, any way to fix this?

Jason June 25, 2010 at 11:48 am

NO WALLPAPER???

I used pwnage and ultrasnow to jailbreak and unlock my iphone 3g (previously jailbroken and unlocked with blackra1n and running 3.1.2) with 5.11.07 baseband. The jailbreak and unlock worked, and I have all features, except for wallpaper. I have wallpaper on the lock screen, but not behind my apps.

Anybody else have this problem? If so, did you fix it and how? Thanks,

P.S. I had some paid apps through Cydia. When I re-download them through Cydia, will it automatically remember that I paid for them, like the App Store does?

Jason June 25, 2010 at 12:05 pm

RE: NO WALLPAPER???

As I was. I did some research and found out that the iPhone 3G does not support custom backgrounds. iOS4 for iPhone 3G still restricts the user to a black background. No problem, I’ll just use Winterboard.

billym June 26, 2010 at 5:03 am

just jailbreaked ma 3g multi tasking, background and contacts fine only thing is ive lost all my tunes, how do i get these back???????????

Jason June 26, 2010 at 10:30 am

Billym,

All your data would be gone when doing an iPhone Restore…

I used pwnage to jailbreak and unlock my iPhone 3G, which doesn’t add any features that the iPhone 3G wouldn’t normally support (i.e. wallpaper and multitasking). I’m gonna try using redsn0w now, but I might break my iPhone by using one hack after another. If so, oh well.

Brian June 26, 2010 at 7:51 pm

OK….I upgraded to os 4.0 on my iphone 3g, then jailbroke using red snow, unlocked with ultra snow, and I cannot get my Edge network to work on my phone! There is no celluar data option to put an APN, just an on or off switch. I’m pretty sure I’ve tried everything but if ANYONE could offer ANY help, that would be great! I’ve restored several tiems, even as a new phone, tried unlockit.nz, did not work.

Thanks in advance

Confused... June 28, 2010 at 8:03 pm

Hey guys quick question. I’ve unlocked my phone several times personally. But my brother used to use AT&T so he’s never unlocked his. Now he’s switching to Tmobile on the 3G and I tried following the steps above except iTunes doesn’t recognize the 3G .ispw I downloaded from this website. I was curious if I could just download the iOs4 from iTunes directly and then jailbreak from there or is this a customized .ispw? (I checked the iTunes version to the version I downloaded and both have the same name except the iTunes version has about 100,000 mb more. Appreciate any help you can give. Thanks in advance.

Confused... June 28, 2010 at 8:16 pm

Quick update:
So far I’ve checked and iTunes claims the .ipsw I downloaded is a firmware which is not compatible? Redsnow on the other hand does not recognize the .ipsw I downloaded from iTunes but it does recognize the .ipsw I downloaded from this website. So now I’m stuck on whether I should try to update via the Apples default .ipsw and then try to unlock redsnow? But then I’d be using different .ipsw’s (apples to turn software into iOS4 and this websites version for Redsnow to unlock). Anyone know if this’ll work?

I had Wifi Prior to Jailbreaking and now my iphone does not detect any wifi signals. I currently updated the firmware to iOS 4 and did the jailbreak. Iphone is a 3g model.
Need some help troubleshooting.. THanks

Desperate June 30, 2010 at 1:18 pm

Hi, I followed the steps outlined here to upgrade my iPhone 3G software to iOS4 and thenn tried to unlock with the red snow beta now my iphone keeps getting to the downloading jailbreak data phase and then the red snow on my computer crashes. Windows claims the program stopped working. N.B. I did try running the red snow in administrator mode but to no effect. Now my phone is stuck on the emergency call screen every time I restart. Can anyone please help? I would really appreciate it.

Hi guys,

following are the specs of my iphone 3GS

Base band 05.13.04
Bootloader 6.4
Model M B717
Firmware 4.0

How do I jail break and run on the vodaphone network in India.

Geert June 30, 2010 at 2:07 pm

@Prashant: I would not have upgraded to iOS 4.0 yet with a 3GS yet, I succeeded with a 3G but failed with a 3GS.

jose varghese July 1, 2010 at 5:07 pm

I tried to download the iphone 3g ios I am getting it as a zip file not an ipsw file , is it the correct format , can i update my iphone with this file or is this file only for mac or somthing like that

trmf July 3, 2010 at 6:42 am

okay i did every thing and the phone is working but not the service on it and i don’t know how to add this repo on cydia ‘repo666.ultrasn0w.com’ if someone can help me with that thanks

Martin July 4, 2010 at 8:47 pm

Hello!

I have problems with the update. Firstly, I have problems while restoring in the normal way in iTunes. The restoring process stops halfway (the progress bar at the iPod). At the same time, my computer goes nuts since iTunes freezes and so on. Therefore, I tried using redsn0w.

redsn0w_win_0.9.5b5-5

Everything goes according to the plan. The stage with “Downloading jailbreak data” completes (I guess), but then there’s suddenly an all white screen. Why, why, why?

I so badly want to fix my iPod. Maybe it is bricked or something, I don’t know. It’s been non-usable since last summer. Thanks!

Ben July 5, 2010 at 2:51 pm

TRMF go to Cydia and let it update then search fro ultrasn0w install it and your done

Martin July 5, 2010 at 3:50 pm

Problem is:

I can’t get into the iPod. All black in DFU mode. Every recovery fails halfway. Can’t get into Cydia or something.

Brandie July 7, 2010 at 5:56 am

Hi all! I have used the jailbreak and unlock and it works GREAT!! I have a 3G. My problem is that everything works, except my cellular network. I am with Telus and cannot seem to find the correct info that I need to add to change my settings. WiFi works great! Does anyone know the setting for Telus? Please advise. Thank you!

Hi, I’ve just got an unlock iphone 3G loaded with 4.0 firmware. Downloaded itunes and how do I go about to jailbreak it? I’ve also tried to locate the ipsw file but couldn’t find it. Can any one help me? Thank you.

Ayman July 13, 2010 at 9:47 pm

Hey guys

can someone tell me what do I need to do with my iphone 3G after the firmware 4.0 update it does not understand the DFU mode. I keep trying hold both buttons power/home and it worked before I am sure since I use to unlock it each release. Please help on this matter

Ayman

Drew July 14, 2010 at 3:42 am

I am lost on steps #4 and #5. I downloaded the ipsw file.

First, recovery mode has the cable/iTunes image on the screen, but the instructions state to put it into DFU mode.

Second, clicking on the shift+restore (mac) and that does not do anything. iTunes still wants to d/l from Apple server.

If I can get past those two issues I think everything will be good.

kdash July 14, 2010 at 8:03 am

hi. all i have some problems after using redsnow to jail break my iPhone 3G MB model with IOS 4.0 .. i found that wireless have some bugs.. at home i able to connect and online and at my work place can connect wifi BUT not able to online.. Not tat as well, Youtube also cant be use after jailbreak. need to use Push Fix to fix it..

Everyone, Do your iPhone 3G will be more lagging / Slow respond while enable @ install with Multitasling ???

Deonardd July 15, 2010 at 2:21 am

Hi Guys
FYI the ipsw Firmware you downloaded is not truly a zip file … Remane from .ZIP to .IPSW
I just jailbroke my iPhone 3g running on the 4.0 firmware with redsn0w 9.5 and unlock it for t-mobile, and it works fine

Ayman July 15, 2010 at 11:12 am

thanks everyone, my son figured out what was the issues. It is not the phone it is with windows 7 and iphone driver some how it is blocked by windows 7.

MJ July 16, 2010 at 6:12 pm

I have a 3G Iphone with firmware 3.1.3 (7E18), baseband 15.12.01. I used Spirit to jailbreak, I got the Cydia icon on my phone, then installed ultrasn0w. I put my Orange sim card in it and it worked fine and I was able to make and receive calls. After I turned it off and on, it is now saying “waiting for activation”. It still says Orange in the top left, but no signal bars.

I reintalled ultrasn0w many times it still doesnt work.
I removed ultrasn0w and switched it back on again, that doesnt work either.

Can anyone help please?

tmac July 18, 2010 at 2:23 am

When I try to restore from itunes while my phone is in DFU mode I get the “…could not be restore because the firmware file is not compatible.” I downloaded the one you provided.
