unlocked-iphoneOh we have a very good news for all those Windows users out there. You will now be able to unlock the iPhone 2G/3G right away without having to wait for the Redsnow tool.

PwnageTool 3.1 was released earlier today by the dev team but the fact that it can only be used by Mac users and leaves no ticket for Windows users seems a little unfair, so we made things a little easy for you.

We created the custom IPSW for Firmware 3.1 on iPhone 2G and iPhone 3G which lets you update without having to meddle with the baseband. This Firmware comes with the stock Apple logo and Cydia. All you have to do is download it, restore it and that’s it.

For the iPhone 3G

Please use the links to download the custom IPSW of Firmware 3.1 for iPhone 3G labeled iPhone1,2_3.1_7C144_Custom_Restore.

http://bit.ly/iphone3g-custom31-sizlopedia

http://bit.ly/iphone3g-custom31-sizlopedia-p2

http://bit.ly/iphone3g-custom31-sizlopedia-p3

Once downloaded, join the file parts using HJSplit and extract the ZIP archive to have one file. Now follow the steps.

  1. Please down and install iTunes 9, and then run it.
  2. Connect your iPhone to the PC.
  3. Click ‘Restore’ while holding SHIFT key and select the custom IPSW.
  4. Once everything is processed and OS boots up, install Ultrasnow.
  5. Follow this guide (starting from Step-3) to install Ultrasnow on iPhone.

Now you have an unlocked iPhone 3G running on Firmware 3.1.

For the iPhone 2G

Please use the links to download the custom IPSW of Firmware 3.1 for iPhone 3G labeled iPhone1,1_3.1_7C144_Custom_Restore.

http://bit.ly/iphone2g-custom31-sizlopedia

Once downloaded, join the file parts using HJSplit and extract the ZIP archive to have one file. Now follow the steps.

  1. Please down and install iTunes 9, and then run it.
  2. Connect your iPhone to the PC.
  3. Click ‘Restore’ while holding SHIFT key and select the custom IPSW.

As no Ultrasnow is needed, so you already done with everything. Notice that no bootloader files are required.

Thats pretty much all of it. Those on Mac can make use of the custom IPSW in case they don’t plan to get their hands dirty with PwnageTool which, to be honest, is not easy to go by due to lack of documentation. The Unarchiver can be used on the Mac to join the files and uncompress them.

Note: Please test and give us your feedback in the comments. Make sure not to ‘Update’ the Firmware at any step, only use the ‘Restore’ feature.

Update: An Exclusive Tutorial for users with iPhone 3GS is now available.

New: iPhone 3G and 3GS users on baseband 05.11.07 can now unlock their iPhone using Blacksn0w! Follow here.

jcrewjcap September 20, 2009 at 6:24 pm

What they fail to tell you is that if you already uploaded the 3.1 via itunes, your screwed because the bootloader is higher than the 3.0 firmware, so if you downloaded 3.1 on itunes your screwed. pretty much that firmware there talking about, custom 3.1, will only work if you did not upgrade to 3.1 on itunes, but upgraded with that custom 3.1 to start with. its pretty complicated, if you have anymore questions feel free to ask

I tried to do the restore both in DFU mode in iTunes 9 and just in regular mode. In DFU mode, I got the 1601 error and it just rebooted my phone and it hand't changed anything. In the regular mode, I got the 1604 error and had to the Restore and Update to get it working again.

Is there anything I am missing?

astalavistababy September 19, 2009 at 8:47 am

Doesn't matter too much as long as you make sure first that custom firmware is already jailbroken. If you want first, jailbreak it with redsn0w and after apply the custom 3.1 already jailbroken. Try not to install the official 3.1 firmware, like I did, because now it gives me lot of headache.

Hi I cant click on “restore” when I connect my iPhone in my pc because iTunes dont let me do anything…its displays the following error : “The SIM Card is not valid for activating your iPhone, please use a SIM card from a valid provider”
The problem is that I upgrade the iPhone (originally this iPhone was in USA with AT&T as the provider) while I put my SIM card which comes from Montreal Canada (provider is FIDO)…
So when I said yes for the upgrade 3.1 it locked everything! iTunes doesn't let me see anything…it recognize my ID (name) but that's it…

4. do i need to downgrade it first?
5. do i need boot loaders?

thanks all!

Reply

Prebster September 19, 2009 at 9:37 pm

Answer to your second question: IF you already upgraded to 3.1, you're pretty much screwed, so if anything, you need to downgrade first, then unlock/jailbrake, then restore with custom 3.1 .ipsw file! No need for the bootloaders, as far as I've understood at least…

Good luck!

Guys you would have to jailbreak your 3.0.1 firmware first n then use this custom firmware, plz update to 3.0.1 first from 3.0 and then jailbreak it and then follow this procedure. It would work. i am 100 percent sure, I just finished 3 iphone 3g…no problems…

I used the RECOVER option, but with another “custom” 3.1 firmware that I found on the quickpwn site as my Rapidshare ratio was done for the day and that site offer direct downloads. I guess this was a big mistake, as it did not work. Having downloaded the one you have here, I can't get it to work (error 1604). Tried to revert back to 3.01 with redsnow 0.8 (I had the files saved for a situation like this but alas, that no longer works, it never goes from the “downloading jailbreak data” HDD icon to the real jailbreaking). Now I can't do squat with my iPhone 2G, so it's resting comfortably in on a shelf as I'm waiting for a miracle (redsnow). It's really worrying that this article does not get updated in any way with what NOT to do, as using iTunes 9 to jailbreak your iPhone clearly is a dangerous move until the 3.1 FW is breakable.

your iphone must be jailbroken before installing custom IPSW 3.1, if u have restored your iphone with official Firmware 3.1 then your baseband has been changed to 05.11.07 :(
just downgrade from firmware 3.1 back to 3.0.1 and once you restored to 3.0.1 jailbreak it and restore with custom IPSW 3.1

downgrade from firmware 3.1 back to 3.0.1 (DFU mode, click+restore) only for 3G and 2G
NOTE: This wont downgrade your baseband

Once you are back to a jail broken phone you can use Fuzzyband to downgrade your baseband to get back to an unlockable phone service.

jorge_04 September 22, 2009 at 3:05 am

Even if you downgrade the firmware, the baseband will not be downgraded; so you can't unlock it

n_g September 22, 2009 at 6:36 am

I had a 1604 error, and spent ages on it. The best advise I got was use itunes 8.2 and downgrade to 3.0 firmware. You will get an error, but it is not 16xx. You then use a windows utility called irecovery to rebot the phone.

This gives you a fresh 3.0 Iphone, with the locked base band.

You can then jailbreak this phone.

I then used Flashband, downloaded by cydia, to restore my baseband to an unlockable version.

And Finally I ran Ultrasn0w.

Took around 30 minutes, once I had worked it out.

Reply

Emphatic September 22, 2009 at 12:14 pm

The irecovery tool works really well, but iTunes 8.2 wants to restore my iPhone to 3.1 and not 3.0. Could you please elaborate on that part a bit?

I'm gonna install iTunes 7.5 now and see if I can go back below 3.1 with that.

If you must do it this way here is a way to findout if your phone is eligible.

FOR THE 3G with iTunes 3.1

After attempting to install the custom 3.1 discribed in the article and

If you get an error like 1604 it doesnt seem to work.

download firmware 3.0.1 and 3.0 for the 3G

Shift+restore in iTunes, open 3.0.1

you will get 90% of the way through but probably get a 1015 Error.

that is good!

You are now in recovery mode

now close iTunes.

Open 2.2.1 PwnageTool

It will ask you immediately to press and hold HOME and POWER for i think 10 seconds, then POWER for 2 seconds. that will system reset and bring you to the Emergency Call screen.

Voila, you have 3.0 again…

NOW use Redsnow 8 and jailbreak with 3.0 install cydia…

Let it do its think… you probably wont have a carrier after all of this, but WIFI works, so open cydia, let it do its downloads, then search a package called FUZZYBAND.

that fuzzyband will check your modem, takes about 20 seconds.

if the fuzzyband completes and it says your eligible for ultrasnow, then click on it, and you will get ultrasnow for Unlocking your phone.

If fuzzyband says your bootfile is too new (5.09) then you are Shit out of luck until DEVteam or someone cracks the new iTunes 3.1 update. ( the reason being is the 3.1 update not only changes the firmware to 3.1 but it also changes the baseband from 4.28.08 to 5.11.07 which might also change your (unlockable bootloader 5.08 to the locked only 5.09)

fuzzyband tells me i'm 5.09 . ultra sn0w from cydia is useless to my iphone 3g [updated to 3.1 by mistake via itunes] i'm screwed :( my only hope is dev team

I didn't read even ONE positive comment about success in upgrading a locked 3G (which has locked official version of 3.0.1 or LOWER) using this file: iPhone1,2_3.1_7C144_Custom_Restore.ipsw

This is my case, and I would be happy to hear if it actually worked to any one of you who are in my situation, because the last think I want is to brick my iphone, or have no signal (the main complaint of the 3G upgraders)

I upgraded the phone from 3.0 to 3.0.1 then jailbroke it and upgraded with the custom firmware to the 3.1.

I've done it three times a couple of times and I still get the same results. It doesn't work.

I have a 16GB iPhone 3G and when I install it I don't get any service.

I have upgrade with the custom FW, works fine, went smooth!
I have 2g Iphone, was on fw 3.0 upgraded with Redsnow.
Be aware that all Cydia apps are removed during the restore process, I don't know if a backup before the upgrade would prevent it, I mean if the apps would be restorable.
Any way, the device is running ok, jailbroken and unlocked and has Cydia, so you may install all apps again.
Thanks to the developer/s

Here is what you have to do in order to get your iphone to work if you have already upgraded to the 3.1 software. you must have someone who has not upgraded to 3.1 restore their iphone using itunes. Then plug your iphone in and hit restore iphone and itunes will unlock it for you. you wont have cydia but at least you will be able to talk and send text messages.

For the iPhone into DFU mode on you can do a restore of firmware via iTunes follow these steps:

Step One
Open iTunes and the iPhone, connect to your Mac or PC.

Step Two
Press and hold the Home button and Sleep / Wake at the same time.

Step Three
After exactly 10 seconds left to push the Sleep / Wake but continue pressing the home button until you see a message saying iTunes has detected an iPhone in recovery mode.

The iPhone will have the black screen is normal.

Once done, connect to the pc and start ITunes, should recognize a device in DFU mode and show the restore button. Remember that you must press the shift button on your keyboard while pressing “Restore” so that it appears the window from which to select the file you just downloaded from this page.

Right ATTENTION ALL 2G IPHONE USERS WHO HAVE UPDATED TO 3.1 VIA ITUNES!!!!All is not lost….I started with: UK 2g iPhone updated to 3.1 via iTunes, Locked to O2. Running iTunes 9.0 on Windows.Firstly I tried to install the original custom 3.1 as in start of this threadFails with 1604 error. When you plug into PC again and connect to iTunes it will display message stating that iPhone needs to be restored. Download official 3.0 software .ipsw file (search in google). Restore using usual “hold shift and click restore” method. Then run redsn0w 0.8. You’ll need to also download the BIN files 3.9 and 4.6 (again used google to find)Run Cydia and do complete update.Then run Cydia and search for “fuzzyband”. Install and Run this to regress Broadbase (or whatever it’s called).Then run file from start of this thread (custom 3.1).I now have my iPhone unlocked & jailbroken running the custom 3.1. It’s working on my new Vodafone SIM. WiFi works, can make and receive calls etc. Everything is functioning as it should.Took a hell of a lot of reading through all the postings on this thread and a bit of trial and error but it DOES WORK. You are not screwed if you updated to 3.1 via iTunes.Note again, this is on a 2G phone. I have never unlocked a phone of any kind on my own before and I’ve managed it so if you’re having trouble – keep trying. It is possible!!!!Thanks to all the helpful and patient posters on this thread. You are Legends! Now we just need to sort out a custom 3.1.2!!!!

notverygood October 17, 2009 at 10:07 pm

This worked on a USA G2 that was at 3.1.

Only note is when Running fuzzyband it said “Querying Modem” then would close. I just went on to the updating to custom 3.1 step in itunes and it went fine.

Something that was always unclear to me is what sim to have in. When I went through this process I had the ATT in. When done I put in the TMobile and all went fine.

I am using an Iphone 3g in Malaysia which bought from USA.
My problem is whenever Apple release the new firmware, i will need to upgrade BUT not from itune directly.
This is causing the problem for me cause it looks troublesome for me .
Every time after the upgrade, all my downloaded programs which already kept the data will be gone and i have to re-sync all programs where the program will be like the fresh one meant i loss all data.
So, is that a way to unlock/unblock the iphone which the same as the Iphone sold in Hong Kong market where it is able to use for all country SIM and can upgrade firmware directly from itune.
Anyone just feel free to provide the advise.
Thank you and have a nice day!

Hello Saad,
please tell me what I will loose on the iphone with this upgrade.

Will the present softwares installed remain there?
What about the phone numbers and sms?
What can happen if I forget (or doesn't work) to press the SHIFT key when restoring from iTunes?

If i update with apple's 3.1.2, my apps that requires 3.1 and above will be installed. I do not want to use blackRain because when you shut down, it requires you to run blackRain again…

Ok quick question(Since reading all of the comments will take too much time)
My iPhone has been unlocked for a long time,It was unlocked in the philippines and i now live in new zealand.Its an iphone 3g with os 2.2.The question is,If i do update my os to 3.1.2 or 3.2.1 will it be “locked” again?

Reply

Josie March 4, 2010 at 2:35 am

yes your phone will get locked. Every update resets certain features in your phone. That is why their are so many unlock methods because with every update the hackers have to find a way to unlock an jailbreak, My answer is based on my research online in regards to unlocking and jailbreakin iPhones. HOpe this helps

Worked as explained – GREAT!!!! I have a 2G, already unlocked running 3.0.1. Downloaded the already combined file mentioned in the listed posts and followed the stated instructions. Went through the sequence with no problems at all. I have been thru some of these problems listed with other software changes/updates, but this one went great. There were apps that required 3.1 or newer that I very much wanted to run and thought I was out on them until this fix.

I did not get a reply back from billwill. What I did was downgrade to 3.0.1 firmware. I then I used redsnow to jailbreak and unlock the phone. As soon as you see the pineapple running you will be very very relieved. If it seems as if your phone is still not picking up your sim card, it's because somehow the update made the sim card malfunciton. I just went and got me a new sim card and my phone is working fine just as before.

In itunes press shft & click restore to access a browse window to select whatever firmware you want to install.

You need to have downloaded v3.0 firmware from somewhere

Reply

Emphatic September 22, 2009 at 10:22 pm

Okay, now I have saved my iPhone!

Here's a little guide (assuming you're not stuck in the “recovery mode loop” *):
1. Download iTunes 8.2 (Google for it)
2. Download the official iPhone 3.0 firmware (I Googled for “iPhone1,1_3.0_7A341_Restore.ipsw” for my 2G iPhone)
3. Start your iPhone in restore mode
4. Use the “Restore” button while pressing shift key and select this Firmware
5. Wait for it to restore (IT FINALLY WORKS! :D )
6. Jailbreak your iPhone with redsn0w 0.8 to 3.01 (no more hanging on the loading screen!)

If you've accidentially upgraded to official 3.1:
7. Open Cydia, let it do a complete upgrade
8. Run Cydia again and do a search for “fuzzy”
9. Install Fuzzyband
10. Run Fuzzyband (I'm kinda guessing here since my iPhone didn't seem to need this)…

*if your iPhone is starting up with no emergency call service, just the iTunes animation use irecovery (Google it)

Nope…by upgrading to 3.1 using iTunes, you upgraded the baseband, the part that controls the telephone portion of the iPhone, as well. This upgrade makes all known unlocks ineffective so you will have to wait until someone figures out how to crack the new baseband firmware.

Reply

odie2828 October 7, 2009 at 8:22 pm

Yes you can download. Depending on your phone search for the 3.0 ispw file for your type of phone(2g, 3g, 3gS). with the phone unplugged start itunes. then hold the home button on the phone, then plug it into your computer while continuing to hold the home button, once you see the screen come up with the USB pointing to itunes then let go of the home button. iTunes will tell you that it needs to restore the phone. click on then hold shit on your computer keyboard and then click restore. navigate to the ispw 3.0 file that you downloaded and it will restore your phone to the 3.0 firmware. then from there you can restore from a backup and then jailbreak it again into the 3.1. if you need any additional help email me. jd@vpcreativ.com

Hi theo…

I started with restore mode first.. by holding the home button and shift+restore in itunes to select the custome restore file. then after sometime the itunes throwed the 1604 error…so i forcefully restared my iphone by holding both power n home button for 10sec.. then my phone entered into the recovery mode loop..
I downloded iREB 3.1 and closed the itunes and patched the recovery loop first.. then put the phone in DFU mode…
( Note : if phone is in recovery mode u will c connect to itunes on screen… if in DFU mode u will c nothing on screen )..

Once u are in DFU go ahead and select the iphone 2g it will ask u to install the libusb-win32-filter-bin-0.1.12.1 if it is not present.. if not download the same and install it.. after patching u will get the white screen and iREB will crash.. now u can opne the itunes and it will automatically asks u to restore now select the custom firmware and upload… after 10-15mins u phone will come up unlocked and jailbroken.. I have WinXP SP3.. iTunes 9.0.1.8.. iREB 3.1..iPhone1,1_3.1_7C144_Custom_Restore ~255MB

theoctopus October 13, 2009 at 7:40 pm

Jaggi,

Thanks alot,

I guess I was not getting into DFU mode because the “itune connect” symbols
was still on the iphone screen. I used a stopwatch to time button pushing
and got a white screen even before activating iREB. I activated iREB anyway
waited for a few seconds then started itune restore. I did not get the 1604
error and the iphone was restore with the custom firmware. It still shows
the apple logo on bootup, but I don't get the “connect to itune” anymore. It
goes to the group of icons and everything seem to work. I don't have a SIM
so I don't know whether that part of the restore works. It shows in
“setting” that the veresion is 3.1 and the carrier is AT&T. Does this mean
that the iphone is unlocked? It also shows a Cydia icon. What's Cydia? Sorry
I have so many questions, but this is my first “unlocking”
Thanks again,

Theo
