HOW TO: Jailbreak iOS 4.2.1 Untethered with Redsn0w 0.9.7b1

As promised, the iPhone Dev Team has released the necessary jailbreak tools which can untether the latest iOS 4.2.1 jailbreak on iPhone 4, iPod touch 4G, and iPad. Old-generation iOS devices already have untethered jailbreak on iOS 4.2.1.

For those who don't know, Apple has already patched the untethered patch in iOS 4.2.1 update so it becomes tethered jailbreak on new-generation devices mentioned above. Being tethered jailbroken means that once your iPhone is successfully jailbroken, you'll need to connect your iPhone to your computer if you ever need to reboot your iPhone or your iPhone loses battery charge. The updates Redsn0w 0.9.7b1 brings untethered jailbreak for those devices on iOS 4.2.1.

Below is the full step-by-step guide to jailbreak your iOS device using Redsn0w 0.9.7b1 and get untethered jailbreak immediately.

STEP 1: First of all, you have to jailbreak your iOS 4.2.1 device using Redsn0w by following the step by step instructions posted here.

STEP 2: Once jailbroken, tap on Cydia and check if your 4.2b3 SHSH blobs saved or not. You should see "SHSH: 4.2b3" in the status as shown in the screenshot below:

STEP 3: Now download Redsn0w 0.9.7b1 from the links given below and connect your iPhone, iPod touch or iPad.

STEP 4: Since this is a beta release, you must have usbmuxd that can be download from here. Now start terminal in python-client directory then type in the following commands:

chmod +x tcprelay.py

./tcprelay.py -t 22:2222

STEP 5: Now start Redsn0w 0.9.7b1 and point it to the official iOS 4.2.1 .IPSW file.

STEP 6: In the next page, check on Jailbreak Monte which untethers your iOS 4.2.1 jailbreak then point it to iOS 4.2 beta 3 firmware (helpful link).

STEP 7: Final step is to put your iOS device in DFU Mode using Redsn0w instructions on the screen.

Finally, sit back and let Redsn0w go in bunch of steps and you'll finally get untethered jailbreak on your new-generation iOS device.

Please note that this is a beta release, and upcoming versions will bring support for Windows users and will have built-in usbmuxd for easy process.

Download Redsn0w 0.9.7b3 for Mac OS X
Download iOS 4.2.1 for iPhone, iPad and iPod touch
Download iTunes 10.1.1 for Windows / Mac OS X

UPDATE 1: Redsn0w 0.9.7b2 is available for download (link above edited), check here for changelog.

UPDATE 2: Redsn0w 0.9.7b3 now available. This version extends the fix made in beta2 over to the non-GUI programs too (like the daemons that handle media content). So now embedded videos in iTunes work. The same link above.

Jailbreak iPod Nano 6G Possible With New Discovered Hack [Video]

James Whelton, Developer has hacked his iPod Nano 6G which he won in some award. He has managed to find out a way to boot iPod by bypassing cache compression of the device which resulting in Springboard installation with creation of blank space. Whelton is expecting it to be a major break through which can help him jailbreaking the iPod nano.

What I have also done is figured out a way for the iPod to boot with modified files (eg the SpingBoard Plist), bypassing the procedure it takes to stop this, I hope this will allow us to figure out a way to jailbreak it. I am primarily focusing on exposing some of the (for now) hidden features of the device.
The springboard hack is just the removal of an app and creation of a blank space. Not that amazing, but whats important is the bypass of Nano’s cache comparison, which compares any modded SB file and reverts it if it doesn’t like it, this opens up the possibility of hacking and modding, while not adding bootloaders or any of that fun stuff.

The innovation could bring many new features like Movies, TV Shows, Apps, Games, vCards, Calender events, passcode lock and much more to iPod Nano.

..in some of the device’s plists of reference to support of Movies, TV Shows, Apps, Games, vCards, Calender events and so on, with a few other cool things like a passcode lock. With the bypass I figured out, I hope to enable these pretty soon. It seems like the OS is a rehashed version of the previous Nano’s OS.

However, currently Whelton don’t have root access on the device neither he has yet installed any app on it but he is expecting that the hack could lead to in jailbreaking the device and he will be able to jailbreak the device very soon.

..the iPod Nano hasn’t been “jailbroken” as some sites claim, I do not have root access over the device. I did not “install” an app. I figured out how to remove them and insert a blank space into the springboard.
What I have also done is figured out a way for the iPod to boot with modified files (eg the SpingBoard Plist), bypassing the procedure it takes to stop this, I hope this will allow us to figure out a way to jailbreak it. I am primarily focusing on exposing some of the (for now) hidden features of the device.

We will update you as soon as we get to know more about it.

Untethered 4.2.1 Jailbreak with Redsn0w jailbreak to untethered one without restore

According to MuscleNerd conversation which took place on his Twitter account, he declared about new features on the upcoming Redsn0w version which will not only allow to be an untethered jailbreak for iPhone 4, 3GS, iPod touch 4G, 3G and iPad running iOS 4.2.1, but it will upgrade the devices which rely on tethered jailbreak to untethered one without restore, you will only need to use the new version of Redsn0w.

Thanks to comex, redsn0w can now handle much bigger files than ramdisk 25MB limit. Useful for "backup plan" 4.2 untether

This also means that you will never lose any data, applications or any tweaks installed from Cydia, thanks for Dev-team for the hard work. About the timing, most of the indicators tend towards the Xmas (Dec 25) at the worste case according to this post. Of cours we will let you know with all updates related to the new Redsn0w. Stay tuned. [via iSpazio]

HOW TO: Unlock your new Nexus S Bootloader ! [Guide]

Two hours ago we reported that Google's Nexus S has got some news today. As most of you know, Nexus S is now available at BestBuy, so in case you are one of the early adopters of this phone, you may ask yourself, “how to root the Nexus S?”

 

For those who don't know, unlocking Nexus S bootloader will allow you to go into custom recovery mode so you can install custom ROMs like Cyanogen Mod etc. The steps are pretty easy but you need to have the basic Android fastboot knowledge. Just follow the step by step [how t guide] below to unlock your new Nexus S bootloader.

STEP 1: Shutdown your Nexus S.

STEP 2: Hold down the Volume Up key then hold the Power key.

STEP 3: Now your device'll get in Standard Recovery Mode.

STEP 4: Now ppen command prompt or Terminal (depending on what OS you’re using, this is on your computer) then type “fastboot devices”. This will tell you if your phone is connected via USB or not.

STEP 5: Type “fastboot oem unlock” if you're connected.

STEP 6: Almost done, now use Volume keys to select ‘yes, unlock bootloader’ then use power button to select option and your new bootloader will be unlocked now !

For now, there is no custom recovery image yet and obviously no custom ROMs but they'll be out very soon. 

Why Cydia is Called Cydia

Cydia is a household name in the jailbreak community. Anyone who has jailbroken their iDevice has most likely used Cydia. Some of us may even know that Cydia is the brainchild of Jay “saurik” Freeman, whom most consider the father of the jailbreak.

Cydia is used by millions of people, but how many know why it has such a weird name? I mean, “Cydia?” What in the world does that mean? There has even been dispute as how to say the word “Cydia.” Little do most know, there is an interesting reason for the odd title behind the icon that every jailbreaker recognizes…

Cydia is actually named after a moth. Cydia pomonella is the scientific name for the “coddling moth,” or what we would most likely recognize as the stereotypical apple worm.

The Wikipedia article on the Cydia pomonella is actually quite ironic in light of Apple’s iPhone: “[it] has proved to be a problematic pest on several fruit trees, including apples and pears. The caterpillars burrow into the fruit, rendering it un-sellable. Traditional insecticides are of limited use, as some strains have acquired resistance to several insecticides.”

Cydia has turned out to be quite the worm to Apple’s ecosystem. With the “jailbreak” becoming more prevalent in the mainstream, Cydia has proven its authority.
While Freeman has been open to any corrections from Latin experts, he has said that the correct pronunciation of the name is “sih-DEE-uh.” If anyone says Cydia a different way, you are free to correct them. So, Cydia is named after a moth.

iBuilder 1.06b - Make Your Own Custom Firmware | Windows Or Winpwn

 
 
 iBuilder, a nifty new project by rotem25, allows you to select from a large list of items for your iPhone, and create a package which can then be added to your internalPackages in iPwnage and used to create a custom firmware for your iPhone.
 
 You can then use iTunes to simply restore your iPhone to the new firmware, with all your favorite apps, sources, or packages already in there. Not too bad...

[Beta Release] Pwn Your Phone with Windows | Winpwn

So there has been constant talk and anticipation for the ability to pwn your phone with Windows ever since the release of PwnageTool for OSX. Now all you windows users can give it a shot with the beta release of Winpwn.


While you can use this to pwn your phone many features are disabled until cmw feels that they are stable enough for the public.

Disabled features:

• 2.0+ support
• Most applications
• Baseband unlocking

What it should do:

Pwn your phone. Create custom pwnd 1.1.4 with installer that is not unlocked.

To Use:

Download Winpwn beta and put the itunes dll file inside the Winpwn program files directory. You may have to put the phone in recovery mode manually if Winpwn doesnt do it automatically.

How to: Use PwnageTool to create custom firmware to jailbreak iPhone 3GS

Except the new iPod Touch, iPhone 2G/3G/3GS and iPod Touch 1G/2G will be able to jailbreak with the latest firmware 3.1. It is necessary for the upgrade since the new software like Dropbox and augmented reality apps only run on the firmware 3.1. You will need a Mac and the latest PwnageTool 3.1.3 at here. It is not that hard to jailbreak, actually. But, it is always useful for some users. Take a look of the simple guide after the break.
It is tested with iPhone 3GS, iTunes 9.0.1 and Mac OS X Snow Leopard 10.6.1. Since PwnageTool 3.1.3 is also compatible with iPhone 2G/3G and iPod Touch 1G/2G. You can also follow this guide if you use other iPhone or iPod Touch.
As usual, don’t blame anyone if the jailbreak is failed. Try it at your own risks.
Step 1. Choose “Expert Mode” from the ToolBar. Choose the device you are using. In my case, I choose iPhone 3GS.

Step 2. Choose the firmware 3.1. If you don’t have it, you can download it from here. Choose the correct firmware with correct device.
iPhone 2G should choose the firmware starts with iPhone 1,1.
iPhone 3G should choose the firmware starts with iPhone 1,2.
iPhone 3GS should choose the firmware starts with iPhone 2,1.
iPod Touch 1G should choose the firmware starts with iPod 1,1.
iPod Touch 2G should choose the firmware starts with iPod 2,1.

Step 3. There are 6 options you can choose. If you want the PwnageTool activate the iPhone for you, you can just click “Build” and “Next” button to build the custom firmware. But, I recommend to change some of them in this guide.

Step 4. Click “General”. If you are using the official carrier and iPhone will activate through iTunes, make sure you don’t check “Active iPhone”. Otherwise, check the option so that you can software unlock with ultrasn0w and use it with the unofficial carrier. Click the “go back” button and the settings will be saved.

Step 5. If you don’t like the custom logo by iPhone Dev Team, click “Custom logos” and make changes.

Step 6. You can click “Cydia packages” and “Custom packages” to further customize the firmware. I personally clicked “custom packages” and removed the “Icy”. I need “Cydia” only. Then, click “build” and click “next” to start to build the firmware.


Step 7. When you have started to build the firmware, select the destination. I saved it on the desktop. PwnageTool will ask the system password. After a few minutes, it will ask you to put the iPhone 3GS in recovery mode. Other iPhone or iPod Touch may need to put in DFU mode. Follow the instructions on-screen on how to put the iPhone in DFU mode.
To put the iPhone 3GS in recovery mode, launch the iTunes first. Then, try to press iPhone’s home and power button at the same time. When iPhone is turned off, quickly release the power button and keep holding the home button. Wait for a few minutes and iTunes will prompt the iPhone is now in recovery mode.
You can also try to turn off the iPhone 3GS first. Disconnect the iPhone from computer. Press and hold the home button, connect iPhone with the computer and launch the iTunes. Keep holding the home button until the iTunes tells you the iPhone is in recovery mode.

Step 8. Press and hold the Alt key. Click the restore button and file dialog should appear. Choose the custom firmware.

Step 9. You should now get the iPhone jailbroken with the latest firmware 3.1. iTunes will ask you whether you want to restore the old settings at the first time. Go and have fun with the latest firmware and old baseband!

iTunes 10.1.1 Download is Available Now for [Windows & Mac]

Apple has just released iTunes 10.1.1 for Windows and Mac, this update of iTunes fixing bugs while playing and syncing music videos, as well as a resolution for unexpectedly quits, as usual I advice for who has a jailbroken device to stay away from using this new version till we get the word from the Dev-team.

Tip: Missing or Hidden Icons

I have written two articles on this. There is the upgrade guide and also the other post that explains why it occurs.

A quick summary of solutions:
1) If you have Cydia still visible you can install Quickgold and simply launch the hidden apps. You can launch bossprefs, poof, or such and unhide it.

2) You can install SBSettings and unhide any apps that are hidden.

3) You can launch settings app and disable / reenable restrictions which should unhide most of everything. (You will then need to use poof, bossprefs, or sbsettings and rehide what you want hidden).

4) If you cannot install anything because Cydia is hidden, you can use apt-get install quickgold from the SSH prompt

5) In the most drastic case where you also do not have SSH, you can use iphone browser and delete the file located at /var/mobile/Library/Preferences/com.apple.SpringBoard.plist. Then reboot.

HOW TO: Watch MegaVideo Videos On Your iPhone And iPad

Earlier today we showed you how to install iOSFlashVideo to watch flash videos on jailbroken and non-jailbroken devices. Now let’s see how to watch megavideo vids on your iOS devices. This time, you will need a jailbroken iOS devices.
What you need:

• Jailbroken iPhone, iPad and/or iPad
• SBSettings
• BUZZ Player for iPhone or iPad ( or something similar )

How to:
1. First load Cydia and add the following repo: http://repo.biteyourapple.net/megalink
2. Install ‘Megalink’ from the newly added repo ( and SBSettings in case you don’t have it installed already )
3. In SBSettings, make sure you have the ‘Fast Notes’ toggle ON.

4. If you don’t , tap on More>Set Toggles> Find ‘Fast Notes’ and turn it ON.

5. Now find a video on MegaVideo that you want to watch, and copy paste its link in SBSettings>Fast Notes. NOTE: you only have to copy it once, and then just replace the old video ID with the new one. If you are confused, a video link looks like this: http://megavideo.com/?v=UQXC4WP1 . The ‘http://megavideo.com/?v=’ part remains unchanged for every video. You will only need to change the ‘UQXC4WP1′ part.

6. Now, load MobileTerminal ( don’t worry, if you didn’t have it installed, megalink installed it for you ) and type:

megalink
exit

7. Now, going back to SBSettings>Fast Notes> you will notice a new link in there. Copy it to clipboard.

8. Now load, BUZZ Player and tap on the 3rd icon at the bottom

9. Paste the copied link from Fast Notes and tap on ‘Go’

10. That’s it. Enjoy the video…

HOW TO: Jailbreak AppleTV 2G Running iOS 4.2.1 With Unofficial Bundle

We don’t recommend you to use unofficial bundles. You should wait on the iPhone DevTeam to drop an official tool. It’s still a tethered jailbreak, and you will need a way to boot into the jailbreaking kernel – redsn0w will not help you in this case.

NOTE: if you don’t like to mess with your AppleTV – and even if you do – we don’t recommend you to use this bundle. We are not aware all ALL its bugs, so anything could go wrong at any time. We are not responsible for your mess-up. Wait on the iPhone DevTeam to drop an official release.
Requirments:

• iOS 4.2 custom bundle
• PwnageTool

HOW TO Create A Custom Firmware:
1. Download everything on your desktop and extract archives
2. Right click on PwnageTool.app and ‘Show Package Contents’
3. Browse to Contents>Resources>Firmware Bundles> and copy the iOS 4.2.1 bundle you downloaded
4. Now close the window, load PwnageTool and create your custom firmware ( MAKE SURE you install OpenSSH in the process )
5. Once you have the custom firmware , load iTunes and click alt+restore ( hold the alt/option key and click on restore )
6. Browse for the custom firmware, select it, and wait for your AppleTV to be restored
7. That’s it. Now you have a jailbroken AppleTV  running on iOS 4.2.1 – except your AppleTV won’t boot in the jailbreaking kernel and now the fun begins…

HOW TO Boot Into The Jailbreaking Kernel:

1. Download and install MacPorts
2. Install libUSB. Open terminal

sudo port install libusb

3. Duplicate your custom firmware and create a folder on your desktop called ‘ Tethereboot’ ( or whatever you want to call it – doesn’t matter )
4. Download the Thetherboot utility and put it in the Tethereboot folder
5. Take the duplicate custom firmware, change the extension from .ipsw to .zip and unarchive
6. Inside there’s two files that you need:

• iBSS.n90ap.RELEASE.dfu
• kernelcache.release.n90

Take them out and put them in the Tetherboot folder along side the tethereboot utility you just downloaded

7. Open Terminal , put your iPhone in DFU mode and type:

cd /User/Desktop/Tetherboot/
./tetheredboot iBSS.n90ap.RELEASE.dfu kernelcache.release.n90

8. Ok, that’s it. Your AppleTV will boot into the jailbreaking kernel.
9. Now you will have to SSH in and add Cydia by following this tutorial.
NOTE: again, if you don’t know what you’re doing DON’T DO THIS. Wait for the iPhone DevTeam to drop an official release

Apple Releases iOS 4.2.1 For Apple TV

As reported by MacRumors, a few minutes ago Apple released a software update for the Apple TV. The build is 8C154 and it’s labelled as iOS 4.2.1 for Apple TV second generation. This is a direct link to the update, courtesy of iOS E Lite. As you can see, it’s a 267MB download.

The update is also available through the Apple TV’s built-in software update checker. A changelog for the new OS hasn’t been provided yet, nor is the update online on Apple’s download website.

In spite of the update file being registered as “iOS 4.2.1″ on Apple’s servers, the Apple TV reports “4.1.1″ as the new installed OS. The same happened on November 22 when Apple released iOS 4.2.1 for iPhone and iPad and announced the availability of iOS 4.2 for the new Apple TV, although the built-in updater tool reported 4.1 as being installed.

According to early reports on Apple’s discussion boards, the update hasn’t fixed the color issues reported by several Philips and Sony TV owners.

Unlock iOS 4.0.1 with Ultrasn0w [How to Guide]

iOS 4.0.1 was released earlier today for iPhone 4, 3GS and 3G. Fortunately for all iPhone unlockers, the baseband wasn’t upgraded from 05.13.04, which means you can unlock your iPhone even on the latest iOS 4.0.1 firmware. Since currently there is no jailbreak tool available for iPhone 4 and iPhone 3GS (new bootrom), and the current jailbreak tools for iPhone 3GS (old bootrom) are not compatible with iOS 4.0.1, so the only device which can currently be jailbroken and unlocked on iOS 4.0.1 is iPhone 3G.
How to: Jailbreak iPhone 3G on iOS 4.0.1:
Step 1: Follow the complete guide posted here to jailbreak your iPhone 3G using Redsn0w 0.9.5b5-5 on iOS 4.0.1.

How to: Unlock iPhone (Any Baseband) on iOS 4.0.1:
Step 2: Once you are done with the jailbreak, you can now unlock your iPhone on any baseband using ultrasn0w 0.93 from Cydia. To do this:

• Start “Cydia” on your iPhone.
• Touch on “Manage” tab on the bottom.
• Now touch on “Sources” as seen in the screenshot below:

xx

• Touch on “Edit” and then on “Add”. You will be prompted to enter a url source as seen in the screenshot below. Type “http://repo666.ultrasn0w.com” and touch on“Add Source”.

xx

Cydia will now automatically update your sources by following a series of automated steps.

• After installation is completed. Search for “ultrasn0w 0.93” in Cydia and install this application. This app will automatically unlock your iPhone so that you can use it with any carrier.

Step 3: Now simply restart your iPhone and voila! you should now have a fully unlocked iPhone 3G on iOS 4.0.1.

Jailbreak iOS 4.0.2 with Redsn0w [How to Guide]

Ok guys I just tested it on an old iPhone 3G lying around and can confirm that this works! Now that Apple has released iOS 4.0.2 to patch the PDF exploit, JailbreakMe which was previously used to jailbreak iOS 4.0.1 on iPhone 4, 3GS, 3G, iPod touch 3G / 2G and iPad is now incompatible with iOS 4.0.2. But if you have iPhone 3G (which doesn’t rely on an unlock) or an iPod touch 2G (non-MC model) lying around, you can jailbreak it using the existing version of Redsn0w. Simply follow the step by step guide posted below to jailbreak the mentioned devices on iOS 4.0.2 using Redsn0w.

Step 1: Download iOS 4.0.2 for your version of iPhone and iPod touch. Download links are given below.

Step 2: Update to this latest firmware using the IPSW file you just downloaded via iTunes 9.2.1.

Step 3: Start Redsn0w 0.9.5b5-5 (download link given below) and point it to iOS 4 (Final Version), and not iOS 4.0.2 firmware file to proceed with the jailbreak.
xx

Step 4: Now select “Install Cydia” and click “Next”.
xx

Step 5: Now make sure your device is both OFF and PLUGGED IN to the computer before you click “Next”.

Step 6: Connect your device in recovery mode by pressing the Power and buttons continuously.
xx

At this stage you will be presented with a screen where you will have to quickly hold “Power” button and then while holding the “Power” button, you will now have to hold “Home” button too. Now after few seconds release “Power” button but keep holding “Home” button until installation begins.
Step 7: Sit back and enjoy while redsn0w will do all the rest for you. Once done, your iPhone and/or iPod touch will restart automatically and you will find it jailbroken on the latest iOS 4.0.2 firmware.
How to Unlock iOS 4.0.2 with Ultrasn0w Once you are done with the jailbreak, you can unlock your iPhone 3G on iOS 4.0.2 with ultrasn0w on 05.13.04 baseband, step by step guide for which is posted here.

Unlock iOS 4.0.2 with Ultrasn0w [How to Guide]

While Apple has released iOS 4.0.2 for iPhone 4, 3GS and 3G, the important thing is that they haven’t updated the baseband. What this means is that 05.13.04 baseband which accompanies iOS 4.0.2 is still unlockable with ultrasn0w provided that you manage to jailbreak your iOS device. At the moment, only iPhone 3G and iPod touch 2G (Non-MC model) can be jailbroken on this latest firmware using the latest version of Redsn0w. So technically, you can only unlock iPhone 3G on iOS 4.0.2.

The steps for unlocking are as follows.
Step 1: First up, you will need to jailbreak your iPhone 3G on iOS 4.0.2 with Redsn0w. Full step by step guide is posted here.
