Developer @sbingner (author of TetherMe) has made some excellent progress devising a new hactivation method that kills two birds with one stone for all you ultrasn0w unlockers. His tool, “Subscriber Artificial Module (SAM)” tricks your iPhone and iTunes into creating legitimate activation tickets even though you’re unlocked with ultrasn0w. This means you get the full benefit of push applications, and your battery life increases substantially. If you’d like to try it out, check out http://www.bingner.com/SAM.html
To help make it easier to try out @sbingner’s tool, we’ve updated redsn0w to include a new “Deactivate” option for the 3G and 3GS. Use this option *after* you’ve installed SAM…it will remove the normal patches made to lockdownd and let SAM take over. (sbingner plans on making a button to do this within SAMPrefs too). Great work, @sbingner!Thanks @sbingner for the hard work, as usual we will prepare the full step by step guide, showing you how to use SAM and the newly redsn0w 0.9.6b6. Stay tuned.
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).For whom is this Guide:
WARNING — YOU DO THIS AT YOUR OWN RISK! PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.
- 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.
- 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).
- 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).
The notion of a “tethered” jailbreak is pretty new to many people, so here’s a quick rundown on what to expect:You can avoid the reasons above to enjoy a jailbreak free of bugs (i.e. White Cydia Icon and/or Safari Crashing), but I highly recommend to wait for the comex untethered jailbreak on 4.2.1 which expected to be very professional (still no ETA). Let me know if you still facing these bugs or not via the comment section, stay tuned.
1. If you’re on an iPhone3G, old-bootrom iPhone3GS, or non-MC ipt2g, life is easy. redsn0w installed an untethered jailbreak and so nothing below applies.
2. “Tethered” does not mean you cannot boot at all without PC/Mac assistance. If you have not installed any tweaks that hook into important programs like SpringBoard or CommCenter, your device will actually boot. However, jailbreak programs like Cydia won’t work (and Cydia may still have a white icon). Also, certain built-in apps that had to be moved by Cydia will fail (Safari being the most noticeable example).
3. If you’ve installed MobileSubstrate tweaks that hook into SpringBoard or other important programs, your boot will actually fail (you’ll get stuck at the Apple logo). You need to use redsn0w to “Just boot tethered right now”.
Remember, @comex and others are working on a way to untether the 4.2.1 jailbreak. Meanwhile, the above 3 points hopefully will make it all seem less confusing :)
redsn0w version 0.9.6b4 is now available for your 4.2.1 jailbreaking pleasure. Please read all the above to understand what this jailbreak currently entails.As usual we will prepare the full how to guide to jailbreak all iDevices on iOS 4.2.1, for now you can check the full details about i|OS 4.2.1 jailbreak and unlock in this post.
We’ve made some updates to redsn0w to make it easier for jailbreak developers (and tinkerers) to get their programs ready for 4.2.1. As noted in Update #2 above, the public version of Cydia (and MobileSubstrate too!) is not 4.2.1-compatible. redsn0w will now let you install your own custom bundles independent of Cydia (the bundle can actually be Cydia if you’ve compiled it on your own). These bundles can be up to 15MB in size, and should be in the form of a gzip-compressed tar file.Again, don't try to do it yourself, PLEASE CONSIDER THIS AN ADVANCED TOPIC!! It's only meant for professionals out there that can use this feature in the new Redsn0w. Anyway, stay tuned and we'll be back with how to guides.
It’s very important that you get the file permissions and ownerships right in your custom redsn0w bundles. To give you a practical example of such a bundle, here’s one that includes OpenSSH, OpenSSL, and the basic apt installer programs:
MuscleNerd: @N44GGA we're about to release a small redsn0w update that will make that much easierSo, 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.
N44GGA: @MuscleNerd just need openssh included thanx
MuscleNerd: @N44GGA yep that's what it will have :)
Today Apple released to developers the GM seed for 4.2. Tinkerers will find that yesterday’s redsn0w jailbreaks today’s 4.2 GM seed, simply by pointing redsn0w at the 4.1 IPSW (rather than the 4.2 one). Right now it mostly only makes sense for JB app developers to do that because many apps (including Cydia itself) need to be updated for 4.2. However, if all you want to do is enable afc2 (to use iFunBox or other file browsers), or to tweak settings like Battery % and Homescreen wallpapers, then go for it (if you have valid paid access to the GM seed). Be sure to uncheck the Cydia box, though! Ultrasn0w unlockers should stay very far away from this!!
- custom bootlogos for iPhone3G/iPhone3GS/iPod2G users (with qualifying bootroms)This tool supports both Mac OS X and Windows. The instructions to jailbreak your device are the same to the previous ones, so you can follow the steps posted here to jailbreak your device using Redsn0w but don't forget to download Redsn0w 0.9.6b2 below.
- an option that implements the “DFU” button in PwnageTool. This button (which you can use from Windows) lets you prepare your device for a custom DFU. Even if you’re purely a Windows user, you can get a trusted friend to run PwnageTool over your IPSW to create a custom IPSW. You can now install that custom IPSW on your own Windows box, after you run this redsn0w version.
@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.
Note: if you have an “MC” model of the ipt2g, your 4.1 jailbreak will be tethered…sorry! (Consider rolling back to a FW supported by jailbreakme.com or spiritjb.com)As usual we will prepare the how to guide to jailbreak your iPhone 3G and iPod touch 2G for Windows shortly, Stay tuned.
Any Windows users seeing “Waiting for reboot” for too long (more than 20 seconds or so), please try “shaking” the JB process by unplugging then replugging your USB cable (while letting redsn0w continue to run). Also, try using a USB port “closer” to your computer (as opposed to on your monitor or behind another hub). We’re still tweaking the Windows flow and so any feedback you can provide will help!
Since some will try it anyway: this redsn0w will also JB 4.2beta1 by pointing it at the 4.1 ipsw, but it's *very* broken (flickers, etc)You can jailbreak iOS 4.2 on your iPhone 3G or iPod touch 2G, but at your own risk, you can check our jailbreak guide posted here, but make sure you browsed on redsn0w to iOS 4.1 (not iOS 4.2), the all other steps are the same. If you are not skilled downing this, so please stay away until it became official. [via redmondpie]
