Dev Team releases 3Gs 3.0 JB Tools

Author : rooster


The Dev Team just released their tools (RedSn0w and UltraSn0w) for the 3Gs running at 3.0. They have also enabled support for Winterboard and MobileSubstrate running the 3.0 version.

They mention that Apple is closing Jailbreakable holes at an increasing pace and that its becoming more and more difficult to jailbreak devices.

Their warning Sounds:

ultrasn0w unlockers — You all must remain particularly vigilent against upgrading your basebands, since doing so will kill the unlock (for most phones, there’s no going backwards in baseband version).  Apple has gotten very serious with the latest baseband — they’ve removed 180 (!) commands in an effort to cut down their exposure to holes.  So please always stay away from stock Apple IPSWs and instead use our tools as we release them.  These tools let you update your firmware without updating your baseband.

Those installing ultrasn0w will probably also need to do a single run of Settings->General->Reset->Reset Network Settings.  We’re testing various fixes for that particular glitch.

Listen up for coming updates.

UltraSn0w not quite ready for 3.1

Author : rooster


The iPhone Dev Team  warns us again not to update the 3Gs to 3.1 quite yet. They have to find a way to update the firmware without updating the baseband. Their current UltraSn0w program uses the at+xlog crash as an injection vector in exactly the same way as the 3G. If you update, it will update both the firmware and the baseband. So they just ask for a bit more patience.

Here is a video of the 3Gs unlock of the 3.0 update.

Another Warning

Author : rooster


So, the dev team has been making almost daily updates with their work in the 3Gs and 3.1beta jailbreak departments. Here is the newest bit. I will warn you, if you are not at least somewhat savvy, then I would walk away right now.

your 3GS temporary solution ;-)

Remember we warned you to stay away from any updates to 3.1 if you want to be able to jailbreak or unlock your 3GS.

Well this is an additional message to all you 3GS owners that would like to jailbreak your device sometime soon, but this advice comes with a warning! A warning that if you accidentally upgrade to 3.1, you will not be able to use Ultransn0w, so please re-read and double check this warning at the bottom of this post before proceeding.

You may have read or heard about techniques to capture files during the iTunes restore process. These will be required to jailbreak your phone in the near future, most of the methods involve icky USB snoops. Well, there is an even better and more reliable method to get your hands on those lovely files.

During the restore process iTunes nicely keeps these oh-so-top-secret-files in a lovely accessible place for us to copy out and backup, that place?  /tmp on Mac OS X or %TEMP% on Windows.  Thanks Apple — handy!

The downside to this approach is that you actually need to go through the restore process to get these signed files, which has risks if you are anywhere near 3.1 or 3.1 beta :-)

If you are ready to proceed and you know the risks we’ll get down to the nitty-gritty -

So during a usual recovery with iTunes, your signed iBEC is written to /tmp and during a DFU mode restore the signed iBSS is written there also. To be sure, restore in both modes one after another to be able to grab them both. You’ll need to keep an eye on the temp directory and copy it before it is deleted again by iTunes. I’m sure some nice folks will create a tutorial about this, we’ll link to the first person who makes a good one.

Should you choose to accept this mission, act fast, this needs to be done quickly! But again, always, always double check here to see if 3.1 has been released, if is has, then don’t do this.

WARNING!! –  DANGER, WILL ROBINSON! – NB! – REMEMBER!

Update: iClarified has come up with a good picture-filled guide for doing this on a Mac and also one for Windows. Good luck!

IF YOU CARE ABOUT ULTRASN0W, BE VERY CAREFUL WITH THIS METHOD! Do not attempt this if you have downloaded the 3.1 beta. You do NOT WANT TO accidentally restore your device to 3.1 beta — you’ll lose ultrasn0w if you do! BE WARNED :-)

All I feel comfortable saying is Good Luck

A well-noted warning from the Dev Team

Author : rooster


Apple released the new 3.1 beta for the iPhone OS today. You’ve heard similar warnings before and know to take heed:

Ultrasn0w users must stay away from any firmware updates past 3.0 (including today’s 3.1 beta) until we release the tools that let you update the firmware without updating the baseband.  For most phones out there, baseband updates are irreversible and you’ll lose ultrasn0w.

The 3.0 jailbreak was one of those (rare) times where both the jailbreak and the unlock coincided (the only other time was 2.2).  It’s important that people realize that *most* firmware releases aren’t like that, and you need to take steps (via the tools) to separate the firmware update from its included baseband update.

This warning does not apply to the iPhone 2G, which uses BootNeuter for the unlock, not ultrasn0w.
