News tagged ‘blacksn0w’

Geohot is famous iPhone and Sony Playstation hacker, the creator of blackra1n and limerain jailbreak methods, as well as blacksn0w unlock. Now he works at Facebook.

Joshua Hill (P0sixninja) recently mentioned this fact in an interview.

Geohot started working at Facebook in May and actually announced it on his Facebook account on June 17th:

"Facebook is really an amazing place to work...first hackathon over."

This means that we should not expect any new iPhone jailbreak and unlock utils from him.

Last Geohot's post on his blog reveals that he will not release any new tool for jailbreak or unlock in the near future. Moreover, he said that he misses those old days, when jailbreaking was a hard work to do:

“...Sorry, this post was probably a bad idea. Next time I won’t say anything. I miss when this blog was actually about technical things (I’ve been reacting too much to the feedback, which led it to the place it’s in now). I didn’t fully realize most of the current scene don’t care unless they are getting something. Now I do. It’s late tonight, I’ll think about what to do about this in the morning.

Apple recentrly released new version of iPhone OS 4. it is called iOS 4.0 GM. Here is an update from DevTeam about iOS 4 jailbreak:

For those who can legitimately activate to the iPhone3G 4.0GM seed, the “point to previous IPSW” redsn0w trick works and will jailbreak your 4.0GM. The “trick” is to point redsn0w at the 4.0beta4 IPSW instead of 4.0GM (do this after you've updated to 4.0GM and activated through the new iTunes 9.2 on your Mac). Since the carrier unlocks aren't yet supported at 4.0, don't do this if you use yellowsn0w/ultrasn0w/blacksn0w. Many JB apps are still pretty buggy in 4.0, so again this is mostly useful only for developers of those JB apps.

Note: If you're experiencing MobileSafari crashes, double check that you're running the version at the bottom of this page.

For those without legit iPhone3G 4.0GM seed access, please wait until the full public 4.0 release for updates to the jailbreak tools.

You can download redsn0w 0.9.5.b4 here.

Last week Apple has released its iPhone Os 4.0 beta 4 and redsn0w is finally updated to support this as well as beta 1. New version of jailbreak is 0.9.5.b4 and it can be applied on iPhone 3G only(!).

Redsn0w 0.9.5.b4 is targeted at developers who make jailbroken apps, and will not work if you are already using blacksn0w, ultrasn0w or yellowsn0w.

iPhone Dev-Team warns:

"You should stay clear of this beta software if you rely on a carrier unlock."

To use the jailbreak, follow the guide below:

1. Download redsn0w 0.9.5.b4 here. (Only Mac OS X version since app are developed on this OS).
2. Make sure you have already activated your iPhone 3G with iTunes and your own developer ID.
3. Launch the jailbreak.
4. Select your stock iPhone1,2_4.0_8A274b_Restore.ipsw (beta4) or iPhone1,2_4.0_8A230m_Restore.ipsw (beta1) file that you used to update your firmware.
5. Choose "Install Cydia" and then click "Next". Use DFU mode to install the redsn0w.
6. When your iPhone 3G comes back up, you will notice Cydia has a blank white icon. It also has no sources so you should go to the Sources panel and add this repo: http://apt.saurik.com/cydia-3.7 (make sure you are connected to the Internet before). When Cydia restarts, you should see its real logo now, and the standard sources should be ready to use.

Geohot, the famous iPhone hacker and the creator of different jailbreak and unlock utilities (purplera1n, blackra1n and blacksn0w), is now working on a new jailbreak utility. It will support untethered jailbreak for all devices with the latest bootrom and the latest firmware. This includes iPhone 3GS and iPod Touch 3G.

Here is what Geohot writes in his blog:

The jailbreak is all software based, and is as simple to use as blackra1n. It is completely untethered, works on all current tethered models(ipt2, 3gs, ipt3), and will probably work on iPad too.

Don't ask about a release date. You won't make it happen any sooner.

It is still unclear if he used one of the recent iPhone Safari hacks to gain control of the device or if this is something else.

Here is a teaser video:

The BlackSn0w Unlock utility by Geohot has been updated by MSFTGuy and PushFix to work with the latest firmware 3.1.3. However it works only with baseband 05.11.07 (!!!).

This modified version of BlackSn0w works for iPhones upgraded with PwnageTool or Sn0wbreeze, preserving the baseband version 05.11.07. Users who have updated to OS 3.1.3 by any other method have the 05.12.01 baseband so BlackSn0w and UltraSn0w will not work.

This new version of BlackSn0w will be very useful for iPhone 3GS OS 3.1.3 / Baseband 05.11.07 users who can’t downgrade to earlier versions but still need unlock.

According to iHackintosh, this new version also fixes a small bug making WiFi much more stable.

Blacksn0w RC2 will be available on ModMyi repo soon. If you don't want to wait just add the source http://cydia.pushfix.info/ to Cydia and install it now.

Important: Blacksn0w for 3.1.3 is still in RC stage and there may be some issues or bugs. This is not an official update performed by Geohot, who has clearly indicated that he will not be updating any tools for the 3.1.3 firmware.

A few days ago in an IRC channel the DevTeam and GeoHot discussed and summarized the state of the exploits found in the new baseband 05.12.01 in firmware 3.1.3. GeoHot explains that an exploit that had previously discovered and used in blacksn0w is still present in the new firmware released by Apple. It appears that both he and MuscleNerd are working on the same exploit, and if this were true, it would be a really good start to team up and release a new unlock tool.

Here is their discussion:

< visnet_ > What does geohot tweet mean?
< %geohot > its my bb exploit for safekeeping
< %Par4doX > geohot: did you turn that over to the dev team or are you doing something with it?
< %geohot > my days of turning things over are done
< %geohot > i hope its different from the one they have
< %geohot > but they prob already have it
< %geohot > its the one i orig wanted to release blacksn0w with
< %Par4doX > it’s still there in the new bb
< %geohot > yep, just checked
< %geohot > but then opted to use xemn since it was public
< Evan > Oo, it carries over from 05.11 to 05.12?
< %geohot > why wouldn’t it, apple doesn’t fix things proactivly
< @MuscleNerd > geohot we prob should figure out a way to know if we have same exploit double blind, otherwise we may release 2 different ones at same time
< %geohot > any suggestions?
< @MuscleNerd > not sure how to do that without making it easy to brute force tho
< %geohot > yea, i salted the hash
< @MuscleNerd > yeah
< @MuscleNerd > hmm maybe if we both hash the stack dump
< @Confucious > Can you two take this out of public sight?
< @MuscleNerd > the stack itself, not the header before it or the registers after it
< Her > muscle: any notice about the exploits are the same ?
< %geohot > we are working on it
< %geohot > cryptography, perfect for people who don’t trust each other

We should not expect much for the firmware 3.1.3 since the rumors predict the firmware 3.2 for mid-March. However these news are really good for owners of locked devices.

Fuzzyband is an application that can downgrade the baseband for iPhone 3G. Recently it has been updated to include the support for firmware 3.1.3 baseband 05.12.01. It works only with bootloader 05.08 (early iPhone 3G).

Why do users need to downgrade the baseband? The answer is simple: if they accidentally upgraded the new firmware and need to run unlock software (blacksn0w and ultrasn0w). Unlocked iPhones do not need Fuzzyband. iPhone 3GS users cannot downgrade baseband with Fuzzyband.

Fuzzyband is available for jailbreaked iPhones in Cydia (repository BigBoss, category "System" ).

Sherif Hashim has discovered an exploit which may allow unlock of the latest iPhone OS 3.1.3 baseband 05.12.01. Such unlock utilities for previous baseband versions were called blacksn0w, ultrasn0w и and yellowsn0w. MuscleNerd, the member of DevTeam, has already confirmed it is working. So the timing of the unlcok release is totally up to them right now.

Here is an official update from DevTeam:

"We’ve started to look at his crash but it’s a long road between any given crash and a fully working unlock, and we couldn’t put an ETA on it even if we wanted to. It’s not even guaranteed that an working unlock will come from this particular crash — it’s just too early to tell."

The iPhone Dev-Team has released PwnageTool 3.1.5 for Mac OS X. It allows iPhone and iPod Touch users to safely upgrade to firmware 3.1.3. With PwnageTool you can preserve jailbreak and ultrasn0w unlock. But if you’re using the blacksn0w unlock with baseband 05.11.07 you will need to stay at firmware 3.1.2.

PwnageTool 3.1.5 creates a custom 3.1.3 IPSW for the following devices:

• iPhone 2G
• iPhone 3G
• iPhone 3GS with early bootrom
• iPod touch 1G
• iPod touch 2G with early bootrom

Warning! Don't try to use this tool if you have  iPhone 3GS with firmware 3.1.3 - it just won't work. If you have iPod Touch 1G, iPhone 2G or factory unlocked iPhone 3G , try to use redsn0w - is would be much easier.

You can download PwnageTool 3.1.5. here.

H8sn0w has just released the new version of Sn0wbreeze 1.4. Sn0wbreeze is a jailbreak utility with functionality similar to PwnageTool. The new version supports firmware 3.1.3 jailbreak for the following devices:

• iPhone 2G
• iPhone 3G
• iPhone 3GS - old bootrom
• iPod Touch 1G
• iPod Touch 2G - non MC

Sn0wbreeze is a Windows application, so Mac users have to wait for the upcoming release of PwnageTool by the DevTeam. Alternatively, both Mac and Windows users can use Redsn0w to run jailbreak (no custom firmware though).

You can download the new version of sn0wbreeze here.

MuscleNerd continues to argue that we should not use sn0wbreeze. Especially users who have unlocked their iPhone with blacksn0w utility:

iPhone hacker Geohot, who created popular utilities blackra1n (jailbreak) and blacksn0w (unlock), posted a message on twitter about the new firmware 3.1.3 released by Apple:

Hopefully some vulnerability in the new firmware will be found.

Apple has just released new firmware 3.1.3 (7E18) for iPhone 3GS, iPhone 3G, iPhone 2G, iPod touch, iPod touch 2G and iPod touch 3G.

The update includes:

• Improves accuracy of reported battery level on iPhone 3GS
• Resolves issue where third-party apps would not launch in some instances
• Fixes bug that may cause an app to crash when using the Japanese Kana keyboard
• Other security updates (more info)

So this is a minor update, which fixing only the accuracy of the 3GS battery meter and the stability of some third-party app launches. This update is avaliable via iTunes.

New firmware 3.1.3 also introduces a new version of the baseband, the 05.12.01. So if you need unlock do not update! DevTeam also warns us:

If you care about your jailbreak and unlock, don’t update your device - 3G and 3G(S) owners should pay particular attention to this warning.
PwnageTool and redsn0w are not yet compatible with 3.1.3

Experimenters show that the latest version of redsn0w 0.9.2 is able to jailbreak iPhone 2G, iPhone 3G and iPod touch 1G. Just point it at the 3.1.2 IPSW (download here) after doing update or restore to firmware 3.1.3. Sounds like DevTeam will release an updated version of redsn0w that will handle firmware 3.1.3 officially. They say iPod touch 2G with firmware 3.1.3 is also jailbreakable.

Users report that unlock software, blacksn0w and ultrasn0w, doesn;t work with the new baseband.

Redsn0w is a cross-platform jailbreaking tool for iPhone and iPod Touch. New version redsn0w 0.9.2 supports the latest firmware 3.1.2.

redsn0w 0.9.2 supports:

• All iPhones and iPod touches
• Windows and Mac OSX (x86)
• Apple firmwares 3.0 and 3.1.2

We expect to see Linux version quite soon.

If you need a carrier unlock, redsn0w will handle iPhone 2G by itself (by installing the BootNeuter utility). For the iPhone 3G and iPhone 3GS use Cydia after you're jailbroken to install ultrasn0w (baseband 04.26) or blacksn0w (baseband 05.11).

If you have a late-model iPhone 3GS, or if you have an iPod touch 2G whose serial number begins with “MC” (newer than week 40 of last year), or any iPod touch 3G, you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting. That means you need to connect your device to a computer each time you boot it - so just try no to reboot.

You can download redsn0w 0.9.2 here.

Redsn0w is a cross-platform jailbreaking, unlocking, and customizing tool for iPhone and iPod Touch. New version redsn0w 0.9b3 supports the latest firmware 3.1.2. The most recent release before this one was redsn0w 0.8, which targeted Apple firmware 3.0/3.0.1.

redsn0w 0.9 beta3 supports:

• All iPhones and iPod touches except the iPod touch 3G
• Windows and Mac OSX (x86)
• Apple firmwares 3.0-3.1.2

When it's out of beta, it will support the iPod touch 3G, PPC OSX, and Linux.

If you need a carrier unlock, redsn0w will handle iPhone 2G by itself (by installing the BootNeuter utility). For the iPhone 3G and iPhone 3GS use Cydia after you're jailbroken to install ultrasn0w (baseband 04.26) or blacksn0w (baseband 05.11).

If you have a late-model iPhone 3GS, or if you have an iPod touch 2G whose serial number begins with “MC” (newer than week 40 of last year), you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting.
