Good news for those who want to untether 4.2.1 jailbreak on Windows. iPhone Dev Team is planning to release redsn0w 0.9.7 for Windows that will bring Monte Jailbreak on Windows. Currently available with redsn0w 0.9.7 beta 4, Jailbreak Monte is a technique that enables you to use previous exploited versions of iOS for untethered jailbreak of iOS 4.2.1 and any forthcoming OS for that matter. In a recent tweet, redsn0w tester said:
Since Apple still serves the 4.1 IPSW (not blobs!), we’ll do a Windows redsn0w release for untethered 4.2.1 via Monte-4.1
Please don’t complain too loudly about how slow it takes The Win version uses filesystem instead of RAM: slow!
Monte Jailbreak will convert your tethered iOS 4.2.1 jailbreak into untethered one. However, as hinted in the tweet, it will be slower than the Mac version. But it will save you the headache of connecting your device to the computer each time you reboot, so it’s worth it.
P0sixninja of Chronic Dev Team sported untethered greenpois0n jailbreak 4.2.1 in a recently released video. Showing off greenpois0n untethered 4.2.1 jailbreak, video features a jailbroken iPhone 4 rebooting without being connected to a PC. Here is the video:
Chronic Dev Team’s greenpois0n uses GeoHot’s limera1n exploit while SHAtter exploit was held back for future jailbreaks. It’s still not clear if they have found a new exploit to make it untethered or if they’ll be using SHAtter. Latter sounds very unlikely. There’s no ETA, let’s see when we get to see uppdated greenpois0n to jailbreak iOS 4.2.1.
This TinyUmbrella 4.2.1 tutorial will help you backup iOS 4.2.1 SHSH blobs. Apple has already released iOS 4.3 Beta 1 and if you upgrade to it, you won’t be able to restore to iOS 4.2.1 if you don’t have iOS 4.2.1 SHSH blobs saved.
Here are step by step TinyUmbrella 4.2.1 instructions to backup your blobs:
P0sixninja of Chronic Dev Team has confirmed that Greenpois0n 4.2.1 jailbreak will be untethered on release. You will get next version of greenpois0n untethered jailbreak for iOS 4.2.1 soon as it’s ready. There are no ETAs. This is what p0sixninja said:
A lot of people are saying another tethered jailbreak is pointless, I agree. Focusing on getting untethered before release
Currently, iPhone Dev Team’s redsn0w 0.9.7 beta 5 allows untethered iOS 4.2.1 jailbreak but that requires you to have iOS 4.2 Beta 3 IPSW. Greenpois0n will not have any such requirements.
@p0sixninja I’m assuming "your own" will require 4.2b3 shsh? And thanks for your guys work!
@Capsfanchad lol no
Lets see if Chronic’s untethered greenpois0n jailbreak for iOS 4.2.1 releases before Comex gets his tool out.
iPhone Dev Team has released redsn0w 0.9.7 Beta 5 for Mac, an updated version that will fix redsn0w bluetooth issues. So, if you did jailbreak iOS 4.2.1 with redsn0w 0.9.7 beta 4 or earlier betas and have bluetooth problems, this version is just for you. All you got to do is to:
Windows version is not released yet although Dev Team are working on it yet it’s too slow to be ready for release. According to Dev Team:
There is actually a Windows version of beta5, but it’s excruciatingly slow compared to the Mac version because it’s forced to use files on your hard drive instead of RAM while it’s processing the very large IPSW images. It really is very very painfully slow, so we probably won’t be releasing it for testing purposes unless it can be sped up somehow.
Let’s see if we get to see a Windows version of this test-release of redsn0w.
iPhone Dev Team have released an updated version of redsn0w 0.9.6 with some bug fixes. It’s a minor update and brings nothing really new if you have already jailbroken using redsn0w 0.9.7 and are not using custom boot logos. It doesn’t support untethered jailbreak for newer devices as yet. According to MuscleNerd of iPhone Dev Team:
For all those using the custom tethered bootlogo cmd line option in redsn0w, rc8 now reports why a given png is invalid
Since you’ll need to boot tethered on each restart, it’s recommended that you create a shortcut for that so that you have to avoid running through the steps each time. This guide will help you doing just that:
How to Boot Tethered iPhone, iPad & iPod Touch
Before you Begin:
Download iOS 4.2.1 IPSW for your device (newer devices only, since older devices already have untethered jailbreak)
Important: For ease of use, put all the files (redsn0w and iOS 4.2.1 IPSW ) at the same location
Now follow this guide:
Step 1: Extract the downloaded redsn0w in C: drive (redsn0w.exe should be on C:)
Step 2: Place the iOS 4.2.1 IPSW on C:
Step 3: Download the one-click tethered boot shortcuts that we created. (Download Link)
Step 4: Run the relevant shortcut for your device. That’s it!
For any of these shortcuts to work, you must have iOS 4.2.1 IPSW and redsn0w.exe to be placed at C:. Id it doesn’t work, follow the method 2.
Now each time you need to boot tethered, just double-click the shortcut that you created and you’re right into it. Not the ideal solution but that’s perhaps the shortest possible way to boot tethered for now.
Method 2: Create Boot Tethered Shortcut
Step 1: Extract the downloaded redsn0w
Step 2: Right click on Desktop, select New > Shortcut
iPhone Dev Team’s redsn0w 0.9.7 for Windows and Mac is now available for download. It still can’t untether 4.2.1 as yet but has added one-click tethered boot support in redsn0w without you having to browse for iOS 4.2.1 IPSW before you see redsn0w options.
Here are release notes, followed by the download links:
We’ve updated redsn0w to include “one-click” support for those of you running the tethered 4.2.1 jailbreak. Using command-line arguments, you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now”.
