UltraSn0w / Signal Bars Issues after 4.3.1 Jailbreak Fixed

Do you have problem with signal bar after jailbreak iOS 4.3.1? Do you still wait ultrasn0w fix to update to iOS 4.3.1?  Well, MuscleNerd has just announced that dev-team has successfully managed to fix ultrasn0w , signal bar and more to work on iPhone 4, 3GS after jailbreaking iOS 4.3.1. All issues will be fixed via a new update on ultrasn0w (not Redsn0w update). Dev-team will release the new update within few days after testing all devices

MuscleNerd: The 4.3.1 issues (signal bars, etc) are fixed http://is.gd/OYktXf but need a few days to test all devices + FW (again: not a new unlock!)

Note: this is not a new unlock, it's only update to ultrasn0w to work on iOS 4.3.1 for the unlockable basebands. (Not supported basebands : 2.10.04 / 3.10.01 / 4.10.01)

iPhone 4 NCK unlock progress [Update]

It looks like the iPhone Dev-Team successfully dumped the seczone to do the brute force NCK cracking offline. It also looks like they were able to capture the official NCK key from their carrier which they needed to “decode” the encryption algorithms that are used to generate the NCK key. That way, in combination with the NORID and CHIPID (and likely some additional information from the baseband), they will be able to generate the the NCK for every unique device out there.

deviceKey = SHA1_hash(norID+chipID)

nckKey = custom_hash(norID, chipID, SHA1_hash(NCK), deviceKey)

(the nckKey is the key that eventually gives the seczone (and so the baseband) the unlocked state).

Right now they are brute force cracking the encryption, which is going to take a few days (if not weeks). If they succeed, progress may be made fast. In the meanwhile they are working on a software unlock. Please note that both are not said to success.

3. Now what? Should I sell my locked iPhone 4?
I’d wait for more information on this “NCK-unlock”. Right now it’s pretty vague what timeframe we’re talking about. If the Dev-Team can pull this method off, it’d be very promising for those waiting for an unlock. If this method turns out to be not doable, I’d consider selling your iPhone 4 and save up for a factory unlocked iPhone 5.

4. Do you think there is ever going to be an unlock?
Of course. But that’s unlikely to be any time soon (with soon being <1 month).


5. If the NCK method fails, how long do you think it will take for the Dev-Team to unlock the iPhone 4 softwarematically? 
No ETA at all. Could be a few weeks, but it could easily be a few months as well. Hope this helps.

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

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.

SHAtter Also Patched in iPad 2, Confirms iPhone Dev Team

Well some more bad news for early adaptors of iPad 2 who wants to jailbreak their shiny new device. After the confirmation of Limera1n being patched in iPad 2’s bootrom, MuscleNerd of iPhone Dev Team has now confirmed that early testing of SHAtter shows that it has also been patched by Apple in iPad 2.

MuscleNerd: iPad2 bootrom version iBoot-838.3 means it was compiled March’10. Seems geohot guessed right: limera1n was already closed

MuscleNerd: Early testing also seems to show at least one thing SHAtter depends on was gone by March 2010 too

MuscleNerd: This means any early iPad2 jailbreaks will have to be purely userland

In case you don’t already know, all the current jailbreak tools are using Geohot’s bootrom based Limera1n exploit to jailbreak iOS based devices on the latest firmware. Since Limera1n exploit exists in the hardware, only a hardware revision from Apple could have patched it. Geohot released Limera1n back in October last year and forced the Chronic Dev Team to save their SHAtter exploit to jailbreak future devices such as the iPad 2.

But unfortunately, Apple had already patched both the exploits back in March 2010, long before they were found by Geohot (Limera1n) and Chronic Dev Team (SHAtter).

So what now? Bootrom based exploits have more life, but they are harder to find as they exist in the hardware. Geohot has been known for finding such exploits but since he is now busy in Sony-PS3 lawsuit, someone like pod2g (who found SHAtter and kernel based untethered exploit for GreenPois0n RC5) will have to come up with a new exploit which will obviously going to take some time. And even if he finds one, I doubt he is gonna release it since iPhone 5 launch is just around the corner (summer 2011).

So now we will have to wait for someone like Comex, who specializes in userland-based jailbreaks, to do their magic and bring yet another JailbreakMe like tool to jailbreak iOS 4.3 firmware on the iPad 2.

As always, we will keep you updated ! Stay tuned for more!

iPhone 4 Unlock Delayed, Apple Beats Devs

Unfortunately, MuscleNerd the well-known iPhone hacker has announced some bad news about iPhone 4 unlock status, he mentioned that it will take longer than they want to finished unlocking task for iPhone 4 basebands above 01.59.00.

Ultrasn0w unlockers should know the drill! Don't let iTunes trick you into installing today's 4.3 iOS. Just say no!

Sorry, there's no news on the i4 unlock for those who lost 01.59 (or never had it). It's taking longer than we wanted :(

So if you rely on ultrasn0w to unlock your device, don't upgrade to iOS 4.3, and don't let iTunes trick you into installing it, just say no!

Diffidently, this news should disappoint who are waiting eagerly for unlock their devices on 2.10.04 , 3.10.01 basebands, but for who have unlocked devices, we hope that dev-team will be able to upgrade PwnageTool to be able to upgrade to iOS 4.3 with preserving the unlockable baseband. let's wait and see.

iPhone 4 Unlock to Follow After Verizon iPhone Launch?

It’s been quite the last few days and people are still asking about iPhone 4 unlock on higher basebands. Look what we have found while perusing MuscleNerd’s Twitter account, the iPhone Dev Team may be waiting for Verizon iPhone’s launch next Tuesday to push their unlock to iOS users.

hishamm126: @MuscleNerd Can we conclude that the i4 unlock is ready but it’s just waiting for the untethered JB?

MuscleNerd: @hishamm126 the Verizon rumor mill is much more relevant :)

This tweet was sent by MuscleNerd in a reply to someone asking him if he’s waiting for the untethered jailbreak to be released. iPhone hacker MuscleNerd answered him saying that the time of release is more relevant to the Verizon iPhone rumors leaked yesterday.

Don't raise your hopes up, but share us what do you think of MuscleNerd's tweet? Feel free to leave comments below.

Downgrade 06.15.00 Baseband iPhone 3GS / 3G on iOS 4.2.1 After Ultrasn0w 1.2 Soon

Here's a bit of good news for who suffered from the new unlockable baseband 6.15.00 on iPhone 3GS and 3G. Most of the unlockers who unlocked their devices with ultrasn0w 1.2 can't restore to any stock firmware above 4.1, it only can be restored to a custom firmware, moreover, ultrasn0w 1.2 caused a loss of GPS. Let's check out the new progress regarding downgrade 06.15.00 baseband.

Lezanz: what about GPS issue? Any progress?

Musclenerd: sorry still collecting data on that. But also working on a bb downgrade (!) method for those with unlockable bb

MuscleNerd has confirmed in a tweet that he is working on a new method to downgrade baseband 6.15.00 to lower versions, which will be unlockable and to fix the GPS issue. Till now we didn't catch more details, but of course will let you know once we catch more, stay tuned.

Untethered iOS 4.2.1 Jailbreak on All Devices Achieved [VIDEO]

As most of you know, comex is currently working on an untethered solution for jailbreaking iOS 4.2.1, but today, the iPhone Dev Team has unveiled one of the many their plans! They got up their sleeves with a backup plan for an untethered iOS 4.2.1 jailbreak for all devices.

As they have mentioned, this is not a new exploit, it’s a ‘backup plan’ as comex is working on a more extensible one, but this method is also generalizable. The method only works if you have already saved SHSH blobs of your iOS device. Anyway, take a look at the video demo below and stay tuned as more updates come!

Unlock iPhone 4 Baseband 02.10.04 Seems Imminent

In case you are living under rocks, you may don't know that Ultrasn0w carrier unlock will be updated tomorrow (this Sunday) to provide a full unlock for iPhone 3GS / 3G on baseband 05.15.04 and lower ones. Anyway, iPhone 4 unlockers will have to wait a bit longer but we have good news for you too.

iPhone hacker Sherif Hashim is doing a great progress in unlocking iPhone 4 baseband 02.10.04 on iOS 4.2.1 / iOS 4.1 since he, according to this tweet, has provided very nice crashes for iPhone 4 baseband, also the iPhone Dev Team will start exploring more starting from this Monday.

Faiz: @MuscleNerd btw @sherif_hashim was working on i4 since long ? Did he not find anything interesting.

MuscleNerd: @mfaizulislam just the opposite :) @sherif_hashim has provided very nice crashes for i4 BB, which we can explore more starting Monday :)

This news gives some hope to iPhone 4 users who stuck on iOS 4.2.1 or iOS 4.1 with upgraded baseband as BB 02.10.04 or BB 03.10.01. More updates as they come! Stay tuned !

Ultrasn0w to Unlock iPhone 3GS / 3G on iOS 4.2.1 Completed

Few moments ago, Musclenerd has confirmed that the ultrasn0w to unlock iPhone 3GS and iPhone 3G finally got working fully on 4.2.1, so it looks that everything over there going alright, everything on schedule, which means that we will catch new version of ultrasn0w tomorrow as we mentioned before.

Musclenerd: Finally got ultrasn0w working fully on 4.2.1. Apple inadvertently(!) broke ultrasn0w via aggressive compiler optimization

Till know there's no news about iPhone 4 baseband unlock. For now we let you know immediately after the release of the new ultrasn0w, stay tuned.

iOS 4.2.1 Compatible Cydia Apps

Everybody’s loving iOS 4.2 for iPad: it brought multitasking to the tablet, folders, AirPlay (sort of) and, ehm, AirPrint. We have already talked about this. As more users upgrade to the new iOS every day and jailbreak it using the latest version of Redsn0w, they need really a list of compatible Cydia apps and tweaks.

MuscleNerd of the iPhone Dev Team has published a spreadsheet on Google Doc showing the compatible Cydia apps, you can navigate to this link to check the list of apps & tweaks in Cydia compatible with iOS 4.2.1. If the color is green that means it works with no problems, if it's yellow it means that it have some problems. Any you know, red ones are unusable and not working. The list should be upgraded consequently when an app gets iOS 4.2.1 compatibility.

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.

HOW TO: Install Cydia Tweaks & Apps using Redsn0w 0.9.6b3

Earlier today we posted that iPhone Dev Team has released Redsn0w 0.9.6b3 with OpenSSH and APT patches which is really useful for app developers who wants to try their Cydia tweaks and jailbreak apps on iOS 4.2.1.

As you know, Cydia is still broken on iOS 4.2.1 and the new version is not out yet but with the latest version of Redsn0w, you can install jailbreak apps without Cydia installed on your iOS device. Your jailbreak-app package must be in gzip-compressed tar format that Redsn0w can read and also it must be around 15MB in size. The iPhone Dev Team already released OpenSSH package can be download from here which is used to install OpenSSH using the instructions below.

STEP 1: Download Redsn0w 0.9.6b3 (Windows - Mac OS X).

STEP 2: Your device must be on iOS 4.2.1, and you have to save .IPSW firmware of iOS 4.2.1 on your desktop (helpful link).

STEP 3: Once you download Redsn0w, launch it and click Browse then select the suitable iOS 4.2.1 .IPSW file for your iOS device so RedSn0w can recognize it.

STEP 4: In this new page, mark on “Install Custom Bundle” & “Just boot tethered right now” options. Then select the package you want to install as shown in the screenshots below:

STEP 5: After few minutes, the tool will recognize the package then click on Next and you will be guided to put your iOS device in DFU mode.

STEP 6: Once your device in DFU mode, it will reboot with SSH package installed. Now use Cyberduck (Mac OS X) or WinSCP (Windows) to SHH into your device.

From now on, you will need to boot using Redsn0w whenever your device is rebooted until comex make iOS 4.2.x jailbreak untethered. So, whenever you want to SSH into your device, you must first run your device in the “jailbroken state” on every reboot by using “Just boot tethered right now” option in Redsn0w. We'll be happy to answer your questions. [via iPhoneItalia]

UPDATE 1: Here's how to install Cydia on jailbroken iOS 4.2.1 devices via SSH enabled devices, check full guide posted here.

Redsn0w 0.9.6b3 Coming Soon Including OpenSSH for Broken Cydia

Here's some good news for iOS users. MuscleNerd has just confirmed on his twitter account that he is about to release a new version of Redsn0w that makes patching Cydia on jailbroken iOS 4.2.1 device much easier. The new version will include OpenSSH to ease the process of installing Cydia on iOS 4.2.1.

MuscleNerd: @N44GGA we're about to release a small redsn0w update that will make that much easier

N44GGA: @MuscleNerd just need openssh included thanx

MuscleNerd: @N44GGA yep that's what it will have :)

So, the new version will include OpenSSH and you'll not need to install OpenSSH in the previous guides to patch the broken Cydia. Anyway, we'll keep you updated whenever the tool is out, or may be they surprise us with the new version of Cydia compatible with iOS 4.2.

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 !

GreenPois0n and Redsn0w Jailbreak Source Code is Going to be Open Source

Here's some great news for jailbreak lovers! GreenPois0n and Redsn0w jailbreak tools will be open sources for all people for free. This means that you will be able to use the source and customize it on your own or may be improve it to make it better than before while adding some interface and designs to the tool. This was confirmed by both iPhone and Chronic Dev Teams.

MuscleNerd of iPhone Dev Team posted on his Twitter account:

@Chpwn redsnow will be open source soon :)

Also p0sixninja of Chornic Dev Team confirmed that GreenPois0n will go open sourced:

p0sixninja: Greenpois0n components will be updated/open sourced as soon as it’s out of beta.

In case you don't know, GreenPois0n was released early this month based on Limera1n's exploit. You can follow our guide posted here to jailbreak iPhone 4, 3GS, iPad and iPod touch using GreenPois0n.

While Redsn0w is used to jailbreak iPhone 3G and iPod touch 2G on iOS 4.1 and it supports iOS 4.2 beta. You can follow our guide posted here to jailbreak iPhone 3GS, and iPod touch 2G using the latest version 0.9.6 of Redsn0w.

Dev Team Releases PwnageTool 4.1 to Jailbreak iOS Devices for Life

Just a couple of hours back, iPhone Dev Team released a new and updated version of PwnageTool to jailbreak iPhone 4, 3GS, 3G, iPod touch 4G, 3G, 2G, Apple TV 2G on iOS 4.1 and iPad on iOS 3.2.2. This tool is based on creating pre-jailbroken custom firmwares, so, you can upgrade your iOS device using this jailbroken custom firmware.

The most important feature in PwangeTool that it preserves iPhone 4, 3GS, 3G basebands, so you can upgrade to higher firmware without updating your baseband. In brief, it will keep your device unlocked. This tool will untethered all A4 devices (i.e. iPhone 4, iPod touch 4G, iPad, Apple TV 2G) for life. It works on Mac OS X only, we will be back with full how-to guide, stay tuned for that!

Download PwnageTool for Mac OS X

PwangeTool 4.1 Jailbreak ALL Devices [SCREENSHOT]

You have waited long for the new version of PwangeTool to jailbreak all devices on iOS 4.1 while preserving the baseband and keeping the carrier unlock safe. So, iPhone Dev Team has teased us with a screenshot for the new version of PwangeTool and the screenshot is really full with devices.

The supported devices as shown are iPhone 4, iPhone 3GS (new bootrom), iPhone 3G, Apple TV, iPad and iPod touch 4G / 3G / 2G thanks to Limera1n's exploit. PwangeTool 4.1 was set to be launched by previous Sunday but I think it was complicated a lot by the team so they delayed the release. But, the screenshot above indicates that it's coming sooner than later! Stay tuned for that!

Untethered Jailbreak Guaranteed for All Future Firmwares on iPhone 4, iPod Touch 4, iPad and Apple TV 2G

Good news for all A4 users (i.e. iPhone 4, iPod touch 4, iPad and Apple TV 2G users) as MuscleNerd has just surprised us by releasing a very important news. He mentioned that the Dev-team have figured out a combination between PwnageTool, limera1n and Comex untethered hacks, this combination will be able to make untethered jailbreaks for all above mentioned devices on all future firmwares.

Think we’ve figured out a way to extend PwnageTool+limera1n+@comex hacks to untethered JBs for all future A4 firmwares :)

Thanks Dev-team for hard work and the guarantee of having untethered jailbreaks for life time. So that Apple will not be able to patch them if it did not upgrade its A4's hardware. We did not catch more news but we let you informed with all immediate updates, Stay tuned.
