Unlock iPhone 4 Basebands 2.10.04 / 3.10.01 New Progress on NCK Unlock

Today MuscleNerd of iPhone dev-team has unveiled some new update regarding iPhone 4 unlock project for basebands2.10.04 / 3.10.01, the news are related to the iPhone 4 NCK unlock which they are now concentrated to crack the NCK's 40 bit code. MuscleNerd has confirmed via his Twitter account that he finally got the SecZone dumper working.

Someone Asking MuscleNerd: Anything positive coming about your NCK attempts?
MuscleNerd Replying: finally got the SecZone dumper working (turns out it's very different than in 2G/3G/3GS, where SZ was simply memory mapped)

You may ask about the meaning of these tecky expressions:

What is the SecZone?

This is the area in the baseband where the lock state is stored.

What is NCK Brute Force?

This is a theoretical exploit which involves brute forcing the NCK from the seczone the CHIPID and the NORID. So far no one has made public an instance of NCK discovery using this theoretical approach.

MuscleNerd also noted that the iPhone 4's SecZone is very different and difficult than the one of iPhone 2G / 3G / 3GS. Today's progress is definitely a new milestone. Now dev-team is working on capture the official NCK code and finally capturing after SecZone then work out an offline BF flow

so the idea is: capture (a) before-seczone, (b) official NCK code (c) after-seczone. Then work out an offline BF flow

after those steps a,b,c, then get back to the SW-based hacked unlock (and revisit BF results when they're done)

On the other hand, you have to know that there is another hardware solution for unlocking iPhone 4 basebands 2.10.04 / 3.10.01 with Gevey SIM you can check out full details about it in This Post.

Restore iPhone 3GS, 3G to iOS 4.2.1 / 4.1 on 06.15.00 Baseband After Using Ultrasn0w 1.2 [How to Guide]

In case you have unlocked your iPhone 3GS / 3G by flashing iPad baseband 6.15.00 with ultrasn0w 1.2 on iOS 4.2.1, and have issues while restoring your device, here is Sherif Hashim the guy behind ultrasn0w unlock tool, has posted a simple guide showing how to restore your iPhone 3GS / 3G to avoid iTunes errors.

Note: To restore your iPhone 3GS from 4.2.1 to 4.1, you must have saved SHSH blobs for iOS 4.1.

For PwnageTool users:

A :  If you are on Mac and use PwnageTool: If you used pwnage tool then you will have to create a “new” custom 4.1 or 4.2.1 and say “No” when you are offered the BB update to 6.15.00 since you already have it, then build the custom ipsw and restore to that.

For Redsn0w users:

B : If you use(d) Redsn0w:

B.1: If you are currently on 4.1, then you can restore to official 4.1 again, and when you see error 1015 pop-up, you kick your device out of recovery mode using TinyUmbrella, use redsn0w and don’t check “ipad BB update” because you already have that Here Is How To Restore iPhone 3G And iPhone 3GS While On Baseband 06.15.00 And Having Issues icon smile

B.2: If you are currently on 4.2.1 then you’ll have to restore back to 4.1 (because 4.2.1 will not allow you to kick the phone out of recovery when 1015 occurs due to the silly BB / iOS mismatch check added there) , then do the same steps as CASE-1.

How to go again to iOS 4.2.1:

If you want to go again to 4.2.1 your only way is to use a custom 4.2.1 done by pwnage tool in the same steps mentioned in A .

Try Hashim's methods above to restore you device between 4.2.1 and 4.1, it worth trying. Don't forget to tell us about your experience.

HOW TO: Fix iPhone 3GS / 3G Battery Drain Problem & Over Heat After Unlocking With Ultrasn0w 1.2

The newly released ultrasn0w 1.2 which unlocked the iPhone 3GS/3G running iOS 4.2.1 by flashing the iPad baseband 06.15.00 using Redsn0w 0.9.6b5 or PwnageTool 4.1.3, has caused two major issues for many iPhone 3GS/3G users, ultrasn0w 1.2 has led to aggressive battery drainage, in addition, iPhone becoming excessively hot. Sherif Hashim, one of the hackers behind ultrasn0w has addressed these issues, let's check out them after the jump.

Here's Hashim justifying these issues

i hope those of u with 3g/3gs are enjoying their updated unlocked devices, all props to @MuscleNerd & co. for making this possible :) , hopefully the iphone 4 on 2.10.04 and 3.10.01 follows within a good time table.

on a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it's the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.

The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.

How can you fix these problems:

so to resolve this, u either:
A) 1st Solution: try to activate the phone using the official sim if u have it (even if the sim itself is old and not working) , or borrow it from a friend if it's possible, by any means, try to have an access to one and use it

B) 2nd Solution: if A is not feasible, u can install SBsettings from featured cydia packages and turn wifi and data off when u r not using it (shuts down both 3g and edge) , till C is done

C) 3rd Solution: there is a very nice module being worked on by a trusted jailbreak app dev, namely @sbingner , which ll resolve that issue for those having it, the details of which shouldn't be disclosed until he finishes his awesome work, till then, either use A or B to resolve the issue if it exists for you

In case you're one of those who suffering from the above mentioned problems after unlocking their devices with ultrasn0w 1.2, you have to try the above solutions as they will handle the situation, but don't forget to feed us back with your results on the comments section.

HOW TO: Update / Unlock iPhone 3GS / 3G Baseband 06.15.00 with Redsn0w 0.9.6b5 on iOS 4.2.1 / 4.1 [Windows & Mac]

Well, here's the iPhone Dev-Team has just released redsn0w 0.9.6b5 to jailbreak iPhone 3GS and 3G on iOS 4.2.1 and update baseband to 06.15.00 which can be unlocked with the newly released ultrasn0w 1.2, the redsn0w 0.9.6b5 is available for both windows and mac users.

The new redsn0w 0.9.6beta5 is out. It gives both Windows and OSX users the ability to flash the iPad 06.15 baseband on iPhone3G or iPhone3GS. It fetches the baseband files directly from Apple for now (the only IPSW you ever point it at is the stock IPSW for the FW on your iPhone right now). There may be a long delay while it’s doing this (their servers are currently getting pounded).

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

For whom is this Guide:
This version of redsn0w 0.9.6b5 is developed ONLY for iPhone 3GS and 3G users who rely on unlock. Precisely,  This guide showing how to jailbreak and update baseband to 06.15.00 for ONLY iPhone 3GS and 3G who have unlocked devices.

Unsupported devices, what have to do:
iPhone 4 and 3GS users who don't rely on unlock, you can follow the same guide but with redsn0w 0.9.6b4 to jailbreak their devices on iOS 4.2.1, see guide Posted Here.

Here's the step by step guide:

STEP 1: Download redsn0w 0.9.6b5,  iOS 4.2.1 for your device(download links at the end).

STEP 2: Update to 4.2.1 firmware using the IPSW file you just downloaded via iTunes 10.1.

STEP 3: Launch Redsn0w 0.9.6b5,  and browse for iOS 4.2.1 firmware final version.

STEP 4: Now you have to select "Install Cydia" and "Install iPad baseband", and then click "Next" (in this step redsn0w will update your baseband to 06.15.00 which works with ultrasn0w 1.2)

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

STEP 6: At this stage you will need to put your iPhone in DFU mode by holding “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: You will Get a Jailbroken Device on the latest iOS 4.2.1  and the unlockable baseband 06.15.00

STEP 8: This step is only for these devices iPhone 4, 3GS (New Bootrom), iPod touch 4G,  3G, 2G, iPad. While this is tethered jailbreak and whenever you want to do anything related to jailbreak like SSH your device, or running Cydia, you must first run your device in the so called “jailbroken state” on every reboot by using “Just boot tethered right now” option.

How to unlock iPhone 3GS / 3G on iOS 4.2.1 / 4.1 using ultrasn0w 1.2 :
This is the final step to get your device unlocked on iOS 4.2.1 / 4.1 with the newly release ultrasn0w 1.2, follow our full step by step guide Posted Here.

Download iOS 4.2.1 for iPhone, iPod touch and iPad
Download Redsn0w 0.9.6b5 for Windows
Download Redsn0w 0.9.6b5 for Mac

Ultrasn0w 1.2 Unlocks iPhone 3GS, 3G on iOS 4.2.1 [How to Guide]

The iPhone Dev Team has just released ultrasn0w 1.2 which brings carrier unlock for iPhone 3GS and iPhone 3G on iOS 4.2.1 or iOS 4.1.

From the iPhone Dev Team Blog:

Today we’re pleased to announce our free carrier unlock for iPhone3G/3GS owners with a baseband later than 05.13.04.  The unlock for that baseband exploited the AT+XAPP command, thanks to a crash initially discovered by @sherif_hashim (@Oranav also found this crash).  So what hole are we exploiting today, since Apple closed that AT+XAPP hole?  Well, we’re exploiting the exact same hole!

It turns out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 still vulnerable to AT+XAPP.  The iPad baseband is built for the exact same baseband chip as the iPhone3G/3GS — they’re fully compatible!  Some of us have been running 06.15 for weeks now on our iPhones in preparation for this release.

Since 06.15 is a higher version than 05.14 or 05.15 (where AT+XAPP is gone), anyone stuck at those versions can simply upgrade to 06.15 to unlock again!  Luckily for us, Apple *still* provides the iPad FW 3.2.2 with this vulnerable baseband right from their own servers. (Grab it now, before they take it down!)
We’ve been busy updating both PwnageTool and redsn0w to make the baseband update as seamless as possible.

1. First up is “PwnageTool 4.1.3 Unlock Edition”.  It has a special dialog box which will ask you if you want to update to the iPad baseband.  You must already have the iPad 3.2.2 IPSW on your computer (see the above link)….so just point PwnageTool at it (or let it find it on its own if you’re in “simple” mode).
2. Directly after PwnageTool 4.1.3 is available, the official ultrasn0w repo http://repo666.ultrasn0w.com will be updated with ultrasn0w 1.2, which covers iPhone 4 baseband 01.59.00 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and now 06.15.00.
3. Finally, we’ll release an update to redsn0w today for those without Macs and can’t run PwnageTool.  The new redsn0w will give you the option to update your baseband to 06.15 too.

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple.  You’ll be voiding your warranty in a very obvious way.
2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Certainly don’t update to 06.15 if you don’t need to!  Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

This PwnageTool also contains a 4.2.1 bundle for iPhone3G owners…for all else, it’s still only 4.1.  If you have an iPhone3GS with an old bootrom, the new redsn0w will handle 4.2.1 for you (in fact it covers 4.2.1 for all devices, even though some of them are still tethered at 4.2.1 until @comex can work some untethering magic).  iPhone3GS users with old bootroms who want to go to 4.2.1 should not use this PwnageTool!  Update to stock 4.2.1 first, then use the upcoming redsn0w to update your baseband.

Please feel free to use our comments section for questions.  We have some very knowledgeable and helpful moderators:  angiepangie, Confucious, dhlizard, and Frank55!

Simply follow the instructions posted below to unlock your iPhone 3GS / 3G on iOS 4.2.1. / 4.1 on 05.15.04 and 05.14.02 basebands.

How to: Jailbreak iPhone 3GS / 3G on iOS 4.2.1:
STEP 1: Unlocking requires that your iPhone is jailbroken. Follow our updated guide posted here to use PwnageTool to update your baseband so you can unlock, or follow our guide posted here to use reds0w 0.9.6b5 (Windows & Mac OS X) to do the same as PwnageTool to update baseband to 06.15.00.

How to: Unlock iPhone 3GS / 3G on iOS 4.2.1:
STEP 2: Once you jailbreak yoour device, you can now unlock your iPhone on baseband 06.15.00 using Ultrasn0w 1.2 from Cydia. To do so, follow the steps below:

• Press to launch Cydia Installer from your SpringBoard.
• Press to select the Manage tab at the bottom of the screen.
• Press to select the Sources button

• Now touch on Edit and then on Add. You will be prompted to enter the URL of the source. Type http://repo666.ultrasn0w.com and touch on Add Source to add this repository. 

• Once the source has been added press the large Return to Cydia button then select the Done button at the top right of the screen.
• Now select repo666.ultrasn0w.com from the sources list and at last select ultrasn0w from the list of packages as shown below then install this application.

STEP 3: Almost done, now simply reboot your iPhone and you should have a fully unlocked iPhone 3GS on iOS 4.1 or iOS 4.2.1.

Unfortunately, iPhone 4 unlockers have to wait a bit longer before they can use their device on any carrier they like but at least they had promised to start working on that starting from tomorrow.

[WARNING] Apple Has Put a Baseband Requirement on iOS

Apple has release iOS 4.2.1, but not alone, it has merged some traps with this version for jailbreakers and unlockers with the introduction of a baseband requirement for iOS starting from the newly released iOS 4.2.1. Precisely, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery.

TheBigBoss: It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainier. Do not update to 4.2.1 even to test it at this point.

So we highly recommend to stay on iOS 4.1 and wait until the situation became stable, specially who want preserve their unlock. for now you can check iOS 4.2.1 features form here, and its jailbreak guide with redsn0w 0.9.6b4 from here. Stay tuned

New Details on iOS 4.2.1 Jailbreak and Unlock

The iPhone Dev Team has just posted a new blog post informing the status of unlock and jailbreak of the newly released iOS 4.2.1. The post starts by warning unlockers to stay away from iOS 4.2.1 until they release new tools to creat custom .IPSW firmwares that don't update your baseband.

However, jailbreak for older devices on iOS 4.2.1 shouldn’t be a problem at all as the post states:

The best news of all is for owners of iPhone3G, older iPhone3GS, and non-MC iPod touch 2G. Due to a combination of our original pwnage2 exploit, the arm7_go exploit, 24kpwn, and limera1n, your device is “just as jailbreakable as ever.” You reap the full benefit of an untethered 4.2.1 jailbreak.

For newer devices as iPhone 4, iPhone 3GS, iPod touch 4G, iPod touch 3G and iPad will have to wait longer for untethered jailbreak

Next are the owners of all the more recent devices. The good news there is that due to geohot’s limera1n exploit, all recent devices can be jailbroken (this will be true until Apple released new hardware that fixes geohot’s limerain exploit in the bootrom). The bad news is that right now, the 4.2.1 jailbreak is *tethered* on all of these recent devices.

Here comes the good news for iPhone 3GS and iPhone 3G who rely on unlock, the iPhone Dev Team has announced that the unlock is ready and will be uploaded to the repo once the new version of Redsn0w is out, this will happen something this week:

ultrasn0w unlock: After redsn0w is officially released with the new Cydia and kernel patches, we’ll be able to assess the unlock situation. It’s already looking very promising though, so expect the unlock for the 3G and 3GS to be coming this week. The i4 unlock is taking more effort though, and no further concrete info is available about that yet.

To sum up what've been said above, you'll all get a semi-tethered jailbreak probably tonight with patched Cydia and MobileSubstrate. For unlockers, only iPhone 3G and iPhone 3GS users will get the unlock this week, iPhone 4 users will have to wait a bit longer. We’ll keep you posted about jailbreak and unlock for iOS 4.2.1 but hopefully, we’ll be able to tweak our iPad folders and settings soon with some exciting tweaks.

iOS 4.2.1 Jailbreak and Unlock: What you Need to Know

As most of you know, Apple today has released iOS 4.2.1 for iPhone, iPad and iPod touch bringing multitasking to iPad, AirPlay, AirPrint, unified mail and some new features to iOS devices. Since I have received lots of questions about iOS 4.2.1 jailbreak and unlock, let's show you what's going on and what's your situation of jailbreaking.

iOS 4.2.1 Jailbreak
There's no new tools released for iOS 4.2.1, but we tried the latest version of Redsn0w and it works on iOS 4.2.1 the same as it done iOS 4.2.1 GM, so you can follow our previous guide posted here to jailbreak iOS 4.2.1 using Redsn0w and then use our guide posted here to patch Cydia and run it on iOS 4.2.1.

iOS 4.2.1 Unlock
Yes, the new version of Ultrasn0w should be released today, tomorrow or this week. It should come out a day or 2 days at most after iOS 4.2 is released (as promised), so we can see it anytime now.

In case you updated to iOS 4.2.1, you will notice that it's baseband is different from iOS 4.1's one but they both will be unlocked by the same tool as the new baseband doesn't catch any holes. We'll have to wait and see what happens.

If you’re on iOS 4.1 and jailbroken, by this point you should know how to save your SHSH blobs via TinyUmbrella to ensure untethered jailbreak as soon as iPhone hacker comex pull another trick out of his hat, the iOS 4.2.1 jailbreak is tethered on all iOS devices except iPhone 3G, iPhone 3GS (old bootrom) and non-MC iPod touch 2G.

Though all this, I highly recommend waiting to upgrade for the official tools, but if you feel the need to give it a try right now.

New Details of iOS 4.2 Jailbreak & Unlock

Just a quick little heads up! iPhone Dev Team has just posted new details about the new iOS 4.2 untethered jailbreak and also they talked about baseband 05.14.02 and 02.10.04 unlock. iOS 4.2 will be released on Friday to bring lots of new features, so the Dev Team promises with lots of things that will satisfy our readers!

By all accounts, we’re within a few days of Apple’s official public release of Firmware 4.2. Here’s what you need to know:
- Thanks to geohot’s limera1n exploit, and our original pwnage2 exploit, and pod2g’s ipod2g-MC exploit, absolutely all devices at all iOS devices at all
- The untethered jailbreak of the very latest FWs and devices depends on @comex hacks. His hacks so far extend only to 4.1 and 4.2beta3. He’s working on a way to extend it to 4.2 and beyond. Just wait for him to work out his method.
- iPhone 3G and 3GS unlockers will be covered by our upcoming unlock. Stay away from any updates to Apple FW until our official release and you’ll be okay. Just stay away from all Apple IPSWs :)
- iPhone4 unlockers are not left out in the cold. @sherif_hashim has found some very promising avenues to pursue. Those will be explored as soon as possible after all the 4.2 madness.

What does this mean to you?
- If you’re an unlocker, just stay where you are. Please, just stay where you are. Any mistakes you make now may be permanent.
- If you only care about the jailbreak, feel free to experiment but keep in mind that any mistake you make may result in you losing pictures or notes or bookmarks that you’d rather keep. Honestly unless you love living on the bleeding edge, it’s better to just wait for official updates from Cydia/redsn0w/PwnageTool.
- Don’t buy or donate to any unlock or jailbreak scammers. Every legitimate solution you will find for unlocks or jailbreaks will be offered without an extended hand. That’s how this community works. It’s about freedom, not donations.

Better explanation? iPhone hacker comex could make untethered jailbreak until iOS 4.2 beta 3 (that's why you see it's SHSH in Cydia) and is working on extending it to final iOS 4.2. iPhone 3G and iPhone 3GS will get Ultrasn0w unlock once iOS 4.2 is released while iPhone 4 will get it a bit more but as soon as possible ! So, stay tuned for some good news here !

Unlock Baseband 05.14.02 is Just a Day After iOS 4.2 is Public

Here's some good news for all people over there waiting for baseband 05.14.02 unlock on iPhone 3G and iPhone 3GS. Few days ago, MuscleNerd the iPhone hacker of the iPhone Dev Team has replied a user asking him about iPhone 3GS unlock on iOS 4.1. the reply will satisfy you a lot.

Here's what MuscleNerd tweeted in reply to the guy:

MuscleNerd: if you’re on 3G or 3GS, just a day or 2 at most after 4.2 is public (just enough time to verify stuff)

This reply brings both bad and good news, why? because he didn't mention anything about iPhone 4 baseband 02.10.04, this may indicates that iPhone 4 unlock may be delayed and not released at this time.

iOS 4.2 should be released early in November (this is very near). To sum it all up, iPhone 3GS and iPhone 3G on baseband 05.14.02 will get the unlock early in November. Stay tuned as we will keep you informed whenever iOS 4.2 is available and followed by the unlock.

UPDATE 1: iOS 4.2 is about to be released as Apple has just confirmed the release date of iOS 4.2 to be launched today in a new press release, check it here. Anyway, the unlock (as promised) will be tomorrow at most as the above post confirms.

Limesn0w Unlock Tool Will Never be Real !

A few days ago we had hopes when we reported you about the Limesn0w unlock tool which was expected as a new surprise from Geohot to unlock basebands 05.14.02 and 02.10.04 on iPhone 3GS and iPhone 4G on iOS 4.1, but now Geohot cut in any doubt, when he announced that Limes0w unlock tool will never be real in his limesn0w.com website.

This will never be real. Media, understand it. ~geohot

So that, if you see any picture or video claiming the unlock of those basebands by limesn0w, they are completely fake.

We have no choice but waiting the new unlock from the Dev-team, for who don't know, the unlock for the above mentioned basebands will be released after iOS 4.2 official release by November.

LimeSn0w to Unlock iOS 4.1 On its Way By Geohot?

It may be real! Geohot may surprise us (again!) with a new unlock solution for iOS 4.1 on iPhone 4, iPhone 3GS and iPhone 3G using Limesn0w. The video below shows iPhone 3GS running iOS 4.1 on baseband 05.15.01 unlocked using Limesn0w solution via Limera1n jailbreak which was released two days ago. It would be a real surprise.

Of course there's a lot of users have updated to iOS 4.1 and now their devices on baseband 05.15.01 or 02.10.04 which is not unlockable at the moment. So Geohot may really surprise us Limesn0w.

The domain http://limesn0w.com is registered by Geohot, the same info as http://limera1n.com but the site indicates that "This will never be real.", you know, surprises! Geohot didn't say any word about that, we'll keep you updated at any update happens.

[Thanks John & everyone else for the tip]

since nearly all my received tweets ask about both BB, I can report very early "initial" 1st step success on both sides, calmed down? :)
