How to Unlock iPhone 3.1.3

Sébastien Page ∙ Updated August 31, 2010

This guide and tutorial will show you how to unlock iPhone 3.1.3 using UltraSn0w or BlackSn0w, depending on your iPhone baseband.

The first step is to jailbreak your iPhone 3.1.3, either with RedSn0w or with PwnageTool. Note that PwnageTool is the preferred method as it helps preserve the baseband.

You can use UltraSn0w to unlock these basebands:

04.26.08 05.11.07 05.12.01 05.13.04

To find out what your baseband is, go to Settings > General > About > Modem Firmware.

How to unlock iPhone 3.1.3 with UltraSn0w Launch Cydia. Add the following source to Cydia repo666.ultrasn0w.com (note there is a “0″ in sn0w, not an “o”). After installing this source in Cydia, search for “ultraSn0w”. Install UltraSn0w and reboot your iPhone. How to unlock iPhone 3.1.3 with BlackSn0w Launch Cydia. Add the following source: http://blackra1n.com. After installing this source in Cydia, search for "BlackSn0w". Install BlackSn0w and reboot your iPhone.

Your iPhone should now be unlocked. If you have questions or comments on how to unlock iPhone firmware 3.1.3, please leave a comment.

Jailbreak Your iPhone 3.1.2 Using Sn0wBreeze

Sébastien Page ∙ January 23, 2010

I had heard several times about Sn0wBreeze but I never really paid attention to it because it seemed to be one of these tools that would never get out of beta. I was wrong!

Today I received a couple emails from readers of the blog with more info about Sn0wBreeze, and Thomas even sent me a pretty detailed tutorial (thanks Thomas).

Sn0wBreeze is a jailbreaking tool developed by some underground developer and from what I understand, it's pretty much a rip off of Dev Team's PwnageTool, except it works on Windows. As a side note, it's important to highlight that the Dev Team came up with an update to RedSn0w (see RedSn0w tutorial here).

Just like PwnageTool, Sn0wBreeze will create a custom firmware for iPhone OS 3.1.2. This is the perfect solution for people who want to upgrade to OS 3.1.2 without updating their baseband.

I haven't tried this myself but as I said above, I got reports from 2 different people that it works flawlessly. Obviously, you should be cautious if using Sn0wBreeze...

This version of Sn0wbreeze only supports the iPhone 2G, 3G and 3GS (non MC) as well as the iPod touch 1G and 2G (non MC) so far.

This step-by-step guide and tutorial will show you how to jailbreak your iPhone 3.1.2 by creating a custom firmware with Sn0wBreeze.

Step 1: Make sure you have the latest version of iTunes installed on your PC. If not, download and install it, then reboot your PC.

Step 2: Download Sn0wBreeze as well as the right firmware 3.1.2 for your device from our download page. To make things easier, I suggest you place these 2 files on your desktop.

Step 3: Launch Sn0wBreeze and select "Simple Mode".

Step 4: SnowBreeze will then ask you to browse for your IPSW file. Click "Browse" and select the 3.1.2 IPSW file you downloaded to your desktop in Step 2.

Step 5: Sn0wBreeze will then verify your IPSW. Click Next to continue.

Step 6: Sn0wBreeze will now ask you if you want to activate your iPhone. If you are on an official carrier (ie. AT&T in the US), say no. If you are not on an official carrier, then click yes.

Step 7: SnowBreeze will now create the custom firmware for your iPhone.

Step 8: Now launch iTunes and we will restore your iPhone using the custom cooked firmware we just created. To do so, hit the SHIFT key on your keyboard while clicking on RESTORE. It's very important that you hold the SHIFT key while clicking! iTunes will ask you the location of the firmware you want to use to restore your iPhone. Browse for the custom IPSW (most likely on your desktop) and select it.

Step 9: Your iPhone will now be restored using the custom firmware. This might take a while so don't stress out.

Done! You have successfully jailbroken your iPhone using Sn0wBreeze. Next step for you might be to unlock your iPhone. Follow this guide to figure out how to unlock your iPhone, depending on what model you have.

Jailbreak iPhone 3.1.2 with RedSn0w 0.9

Sébastien Page ∙ Updated January 31, 2010

This guide and tutorial will show you how to jailbreak your iPhone 2G, 3G or 3GS running OS 3.1.2 using RedSn0w 0.9.

If you are new to the whole jailbreaking thing, I really suggest you read this information about RedSn0w 0.9. It will tell you everything you need to know about RedSn0w before starting.

I know that some of you won't bother reading the more info link about RedSn0w 0.9 so here is probably the most important information about this jailbreak:

If you have a late-model iPhone 3GS, or if you have an iPod touch 2G whose serial number begins with “MC”, you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting. That means you need to connect your device to a computer to complete the boot after a reset. Also, these devices cannot have custom logos.

redsn0w will ask you whether or not you fit in this category when used with the iPhone 3GS or iPod touch 2G. If you have a late-model device and don't give redsn0w the correct answer, you will likely need to do a system restore to recover from the mistake.

To do a tethered boot after your late-model device resets for some reason, either run redsn0w again and select “Just boot tethered right now”, or run blackra1n.

This RedSn0w tutorial was written for Windows but I assume the steps are identical for a Mac.

Step 1: Download RedSn0w 0.9 for Mac or PC as well as the correct 3.1.2 firmware for your iPhone from here. To make things easy, save those 2 files on your desktop.

Step 2: Make sure you have the latest version of iTunes installed on your computer, then restore your iPhone to the latest firmware 3.1.2. Restoring is the preferred way to go about it as simply updating could cause issues later on.

Step 3: Launch RedSn0w and browse for the 3.1.2 firmware you downloaded to your computer in Step 1.

Step 4: RedSn0w will automatically check if you chose the right firmware (IPSW). It will then patch the file.

Step 5: For iPhone 2G only (other please skip to step 6)! You will then be offered several options. If you have an iPhone 2G and you want to unlock, now select "Install Cydia" and "Unlock". You will have to download the bootloaders 3.9 and 4.6 from here. If you just want to jailbreak, disregard this and go to step 6.

Step 6: You will now have the option to "Install Cydia" as well as "Custom boot logo" and "Custom recovery logo". For the purpose of this tutorial, I suggest you only choose "Install Cydia".

Step 7: Make sure your iPhone is plugged to your computer. RedSn0w will now dictate you a few steps to have your iPhone enter DFU mode. Follow the onscreen instructions very carefully.

Step 8: Your iPhone will reboot when successfully jailbroken.

Congratulations! You just jailbroke your iPhone using RedSn0w 0.9. If you want to unlock your iPhone 3G or 3GS, simply install UltraSn0w from Cydia.

Any question or concern, please feel free to ask in the comment section below. Happy jailbreak :)

UPDATE: People have encountered quite a bit of problems when running RedSn0w o.9 beta 3 with an iPhone 3GS. Thankfully MuscleNerd has been updating RedSn0w and the 3GS issues should now be gone. You can download the latest RedSn0w from our iPhone downloads page.

Tutorial: Jailbreak iPhone 3.1.2 with BlackRa1n RC3

Sébastien Page ∙ November 3, 2009

Ealier today, GeoHot unveiled BlackRa1n RC3, his latest jailbreak for iPhone OS 3.1.2. BlackRa1n RC3 is very similar to RC1 and RC2. The difference is that RC3 includes BlackSn0w, the unlock for iPhone baseband 05.11.07.

This step by steps guide and tutorial will show you how to jailbreak your iPhone OS 3.1.2 with BlackRa1n RC3. The steps are strictly identical to BlackRa1n RC1 and BlackRa1n RC2 but I figured it might be good to write a tutorial for novices.

This BlackRa1n RC3 iPhone jailbreak tutorial will work on both Mac and PC. If you already jailbroke your iPhone using BlackRa1n RC1 or RC2, there is no need for you to run BlackRa1n again.

How to jailbreak iPhone firmware 3.1.2 with BlackRa1n RC3:

Step 1: Update iTunes to the latest version available and reboot your computer. If your iPhone is not running OS 3.1.2, update your iPhone to firmware 3.1.2 in iTunes.

Step 2: Download BlackRa1n RC3 from our iPhone Downloads page.

Step 3: Plug your iPhone to your computer and make sure iTunes is closed. Run BlackRa1n RC3 and click on "make it ra1n".

Step 4: Your iPhone will enter recovery mode and you will see the usual recovery image replaced by a picture of GeoHot.

Step 5: BlackRa1n will run on your iPhone and it will reboot when done.

Step 6: A message will show up asking to donate. If your jailbreak is successful, I think it's the right thing to do to donate $5 or more. It's a good way to keep GeoHot motivated.

Step 7: After your iPhone has rebooted, you will notice a new BlackRa1n icon on your springboard. Make sure you have an internet connection and launch BlackRa1n.app on your iPhone.

Step 8: You will now have the option to install Cydia, Rock, or both if you choose to, then tap "install". You will also notice that Icy is gone and it's been replaced by "sn0w". Run "sn0w" only if you want to unlock your iPhone.

Step 9: Once the packages are installed, your iPhone will respring and you should see Cydia (and Rock if you chose it) on your springboard.

Step 10: Once Cydia and/or Rock are installed on your springboard, you can now uninstall BlackRa1n from your iPhone. Uninstalling BlackRa1n will obviously not remove the jailbreak. It will simply remove the BlackRa1n.app that was used to install the packages. To do so, simply launch the BlackRa1n.app and select "uninstall BlackRa1n".

Step 11: After uninstalling BlackRa1n, I suggest you reboot your iPhone.

Done!

The whole process shouldn't take more than 10 minutes. It definitely is an easy jailbreak.

If you have questions, please feel free to leave a comment below.

Tutorial: Jailbreak Your iPhone With BlackRa1n RC2

Sébastien Page ∙ Updated January 23, 2016

GeoHot came up yesterday with an updated version of BlackRa1n called BlackRa1n RC2. This new release supposedly fixes a bunch of issues that some of you may have encountered, especially while trying to jailbreak an iPhone 3G.

This step-by-step guide and tutorial will show you how to use BlackRa1n RC2 to jailbreak your iPhone or iPod Touch, either on a Mac or a PC. This works for all iDevices, except for the iPod Touch 3G. This tutorial was made using an iPhone 3GS but again, it should work on all devices except the iPT3G.

I already wrote a BlackRa1n tutorial and the steps are identical but a few people emailed me or tweeted me asking to write a tutorial for BlackRa1n RC2.

Before we start, you have to understand that BlackRa1n is a jailbreak and jailbreak only. BlackRa1n will not unlock your iPhone. As a matter of fact, if you want to unlock your iPhone, do not use BlackRa1n as it will update the baseband and make it impossible to unlock for the time being.

If you want to unlock your iPhone, I suggest you use PwnageTool. PwnageTool will help you create a custom IPSW that won't update your baseband, thus allow you to unlock using UltraSn0w.
