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.

Step 2: Since Redsn0w doesn’t hacktivate iPhone 3G, you will need to first activate it using original official supported carrier SIM, or the phonebook SIM card trick, guide for which can be found here.

Step 3: Once activated, you can now unlock your iPhone 3G to run it on any carrier you like by unlocking it using ultrasn0w from Cydia. Steps for installing ultrasn0w can be found here.

How to Downgrade iOS 4.2.1 to iOS 4.1 / 4.0.2 / 4.0.1 on iPhone 4, 3G, 3GS, iPad and iPod touch [Tutorial]

iOS 4.2.1 has released for iPhone 4, iPhone 3GS, iPhone 3G, iPod touch 4G, iPod touch 3G, iPod touch 2G and iPad. iOS 4.2.1 contains new baseband for all iOS devices which makes it impossible to jailbreak. Now we are going to show you step by step instructions to downgrade iOS 4.2.1 to iOS 4.1 / 4.0.2 / 4.0.1 on iPhone 4, 3G, 3GS , iPad and iPod touch. If you upgraded to iOS 4.2.1 then you can downgrade back to iOS 4.1 / 4.0.2 / 4.0.1. Follow the steps carefully.

NOTE: You should have SHSH blobs saved for the respective firmware you downgrading to.

INSTRUCTIONS

STEP 1. Download the required old ipsw firmware files. (Download iOS 4.1, iOS 4.0.2, iOS 4.0.1)


STEP 2. Now put your device into DFU mode

• Connect your iPhone to the computer
• Turn off your iPhone
• Start iTunes
• Hold Home and Power buttons together for 10 seconds
• Keep holding the Home button until your computer recognizes a new USB device and release Power button
• Now iTunes will recognize your iPhone

At this time your iPhone screen should be blank
(Skip Step 3 and continue from Step 4 if you are on iPhone 3G or iPod touch 2G (non-MC model))
STEP 3. This step is for iPhone 4, iPhone 3GS, iPod touch 3G and iPod touch 2G (MC model). You should have your SHSH files saved on Cydia for the firmware you downgrading on otherwise you cannot downgrade.

• Navigate to C:\Windows\System32\drivers\etc\ and locate “hosts” file

Mac OS X users can get to “/etc/” directory by going through “Go –> Go to Folder” from Finder.

• Open this “hosts” file in Notepad (for Windows) or TextEdit (for Mac OS X) and add this line

74.208.105.171 gs.apple.com

As shown in the image below:

Now simply save this file.
For Mac OS X: You should have full write and read access on your account when you are saving the host file. If it still shows permission error, simply copy the host file to desktop, make the required changes, and then replace it with the original file in “/etc/” directory.
For Windows 7 and Vista: Start “Notepad” with Administrator privileges by right clicking on “Notepad” app, and click on “Run as Administrator“ option.


STEP 4. Now you will have to restore your iPhone, iPod touch or iPad to the firmware you downloaded in Step 1. Then click on your iOS device icon from the sidebar in iTunes. Now press and hold left “alt” button on Mac (Left “Shift” button on Windows) on the keyboard and then click on “Restore” button in the iTunes and then release this button. (Do not “Check for Update”)





Now iTunes will prompt you to select the location for your downloaded firmware file. Select that ipsw file and click on “Open”.


STEP 5. Now iTunes does the rest for you. Wait for sometime while iTunes installs the requested firmware on your iPhone. A progress bar indicating installation progress will be shown on your iPhone screen. At some points iTunes will throw 1004 or 1015 error. You should ignore this error as the firmware has already been installed on the device successfully.







STEP 6. At this point your iPhone will be stuck in Recovery Mode and shows “Connect to iTunes” screen. To exit your iPhone from Recovery Mode, download TinyUmbrella (Mac / Windows), run it and then click on “Exit Recovery” button. Now your device will restart normally.





That’s it, now you should be able to jailbreak your device on iOS 4.0.x with JailbreakMe and jailbreak your device on iOS 4.1 using Limera1n. After you have jailbroken your device, you can follow our step by step instructions posted here to unlock your iPhone on iOS 4.x, on older baseband using Ultrasn0w. Stay tuned with us for more updates.


STEP 7. Now you must remove 74.208.105.171 gs.apple.com line from the host file so that you are prompted for future updates from Apple via iTunes

CDMA iPhone coming soon

Apple Hiring Engineers To Work On Verizon iPhone?

In what is being seen as yet another indication of Apple's plans to eventually bring the iPhone to Verizon, the company is learned to be scouting for engineers who have experience with Verizon's CDMA technology.

In a fresh posting on the Apple Jobs portal, the company has sought for a "Cellular Systems Perf Engineer” who is familiar with technologies like CDMA in addition to GSM, GPSRS, EDGE, WCDMA, HSDPA and HSUPA.

While the job posting itself has been removed since then, the experience requirements has raised an important point about the potential new cellular technologies that could be supported on Apple iPhone in future. To be fair, the posting makes it clear that Apple is simply looking for an engineer who is a versatile cellular expert and not someone solely with experience in CDMA technologies.

Nevertheless, with a lot of rumors in the past few months pointing out to an imminent launch of a Verizon iPhone, we wonder if this new position could be related to these speculations as well. It is also interesting to note that this is not the first position at Apple for engineers with expertise in the CDMA space. A quick search on LinkedIn gives us a list of quite a few engineers with expertise in CDMA technology.

It should also be noted that recruitment of CDMA engineers do not necessarily imply that a CDMA iPhone could be coming to the American market. Several countries, including China and India, have a growing telecom market with a number of large CDMA players. It is likely that Apple may be working on a CDMA variant of the iPhone to target these markets.

But with competition from Android heating up in the US, it makes a lot of strategic sense for Apple to launch a Verizon iPhone. In fact, analysts have pointed out that such a move could help Apple increase its market share drastically. That makes us believe this recent posting could be hinting at the arrival of a CDMA iPhone in the not-so-distant future.
