Where to Download Absinthe 2.0

For those who are already on a tethered jailbreak on 5.1.1 (iPhone 4, 3Gs etc), then all you need is to install a package (via Cydia) which has been released by the iPhone Dev-Team called Rocky Racoon (cool name) which will untether your idevices. So there is no need to restore the iPhone to 5.1.1 and run absinthe 2.0

Here's the news from iClarified regarding Rocky Racoon

Rocky Racoon Package Untethers Your Previously Tethered Jailbreak

iOS 5.1 information

2. iPhone 4s CANNOT BE JAILBROKEN at this time for iOS 5.1 so if you are already jailbroken on 5.0.1 DO NOT BE SILLY AND UPGRADE. Stay where you are and I'll keep this thread posted.

iOS 5.0.1 Information

1. iPhone 4s - Absinthe Jailbreak tool is now available for Mac OS and Windows for iOS 5.0.1 (both Build) and 5.0

The latest redsn0w version 0.9.10b8 can also be used to jailbreak iPhone 4S on 5.0.1

2b. iPhone 3Gs iOS 5.0.1 - Jailbroken via Corona Exploit : Use redsn0w version 0.9.10b8 or Pwnagetool

I found this iPhone Jailbreak Wiki which is very useful to see the Jailbreak Matrix (The tools used for jailbreaking for each iPhones firmware)

Jailbreak Matrix


Below are the Guides for each iPhone devices.

iPhone 4s

Since the Absinthe tool uses the backup and restore injection method, it is probably a good option to backup and restore your iPhone 4s first (and set it up as a new phone) before running the Absinthe program. If you have a huge backup, it has been reported that the jailbreak process took a long time. You can always restore the backup of the 4s once all the jailbreaking process is completed.

How to Untether Your Previously Tethered Jailbreak Using Corona [5.0.1]
A lot of the time when you need to jailbreak, you will need to download a fresh iPhone Stock firmware (DO NOT TOUCH THESE KIND OF FIRMWARE IF YOU ARE USING A LOCKED SET!!!!!)

You can find the location of the files in the link below

Where To Download iPhone Firmware Files From

One of the most used jailbreaking tool is redsn0w and below is the link where you can download whatever version of redsn0w you want

Where to Download RedSn0w From
I will try and keep this OP updated from time to time.

Happy Jailbreaking!!!


Firmware Versions, Baseband (Modem Firmware Versions) Information[/b][/u][/size][/color]

The link below will point you to a nice site (though a bit outdated) with the iOS Firmware Version for each iDevices and it's Corresponding Baseband (important for that unlock etc). As per De.Si.Mon request

Firmware and Baseband Version Matrix This info is a bit outdated (up to iOS 4.2.1)

For the latest Matrix, please have a look here

Another good site for the firmware and baseband version table can be found below

UNLOCKING

This only applies for those who are on Locked Sets (usually those who bought from shops where the dealer brought in Locked Sets, mostly AT&T sets from the US).

Unlocking and Jailbreaking are 2 different things. However, since you will need to jailbreak to unlock, then I suppose, it is relevant to the jailbreaking discussion.

What is Unlocking? It's a method that allows you to enable your Locked Sets to use any SimCard with your iPhone.

What is a Locked Set? iPhone sold in many countries (especially the US) are locked to a certain service provider and the iPhone will only accept that particular service provider's simcard.

How do I unlock my locked sets?

1. Software Unlock - supports some baseband (modem firmware) via ultrasn0w. Support 4.26.08, 05.11.07, 05.12.01, 05.13.04, or 06.15.00 on the iPhone 3GS, or baseband 01.59.00 on the iPhone 4,

UPDATE: Those on the iPad Baseband 6.15.00 have a way to downgrade to the unlock-able 5.13.04

The iPhone Dev-Team (@musclenerd) has released the latest redsn0w which will enable those with the 3Gs on b[/SIZE]aseband 6.15.00 to downgrade to baseband 5.13.04 (which can be unlocked via ultrasn0w).

Guide on how to do it can be for below

For Windows: http://www.iclarified.com/entry/index.php?enid=22652

For Mac: http://www.iclarified.com/entry/index.php?enid=22653

The iPhone-Dev team has released another update to redsn0w to enable easier downgrade for those that was having issues before. Read all about it from the horses mouth http://blog.iphone-dev.org/

UPDATE: UNLOCK FOR ANY BASEBAND ON ANY FIRMWARE VERSION FOUND - This no longer works as Apple has closed the loophole.

A Chinese hacker (Locktar_Sun) has managed to find an exploit that can UNLOCK any jailbroken iPhone on any firmware and on any baseband. This has been confirmed as legit by Musclenerd. Please follow the guide from the link below

http://www.redmondpie.com/how-to-unlock-an...d-and-firmware/

How to Unlock your iPhone 4s, iPhone 4, iPhone 3Gs using SAM (5.0, 5.0.1, 5.1)

Video Demonstrates How to Unlock Your iPhone Using SAM [Watch]

How to Unlock Your iPhone Using SAM [Easier]

This would be the best news for those who have been waiting patiently (especially hose 3Gs owners who did not want to use the iPad baseband) for an unlock

UPDATE: APPLE IS FIXING THE TICKET ACTIVATION SERVER SO SAVE YOUR UNLOCK TICKETS NOW!!!!

2. Hardware Unlock - via Gevey Sim (Supports the iPhone 4 on baseband higher than 01.59.00)
UPDATE: There are reports that the latest Gevey Ultra will support iOS5.x BUT, you will need to PRESERVE the 4.10.x baseband. We are not sure if a preserve baseband lower than 4.10.x on iOS5.x will be supported or not.
UPDATE 2: There are confirmed reports and reviews of hardware unlock solutions for both the iPhone 4 on iOS 5.0.1 with baseband 4.11.08 AND the iPhone 4s.

What happens if I'm not on those baseband mentioned

1. For the 3Gs, you can install the iPad baseband (6.15.00) but there is no way back from this baseband. This baseband has been reported to introduce issues with notifications, Location Services and basically killing your GPS. Your choice.

Apple has come out with a new firmware, can I upgrade?

Be very very very very very very (I cannot emphasize this enough) careful about upgrading. You Must Preserve Your Baseband or your will lose your unlock. The only way to preserve your baseband is via creating a Custom Firmware using either Redsn0w/Sn0wbreeze (Windows) or Redsn0w/PwnageTool (Mac)

Please follow the tutorial from the link below on how to Jailbreak AND Preserve your baseband (including the iPad 6.15.00 baseband for the 3Gs).

[How To] Preserve Baseband & Jailbreak iOS 5.0.1 using sn0wbreeze 2.9

The link above has a bit more detail than some of the link from RedmondPie especially with the explanation of the choices you have to make.

If you are on a locked set, before proceeding with changing anything with your iPhone, post your iPhone details and ask our members opinion. You really do not want to turn your iPhone to an expensive iPod Touch.

I'll update this information further when I have the time.

DOWNGRADING

There will be times when you will decide if the latest and greatest iOS from Apple is suited for you. There will be times when your Cydia apps that you bought and can't live with is not compatible with the latest version of the iPhone firmware, and thus you've decided to downgrade the firmware

Complete Tutorial on How to Jailbreak/Downgrade/Re-Restore your iPhone (All Versions)

You CAN ONLY downgrade if you have the following

1. The unique (no you cannot use any other iphone's i.e your brother/friends/sisters etc) SHSH - SHSH is a unique identifier for each iPhone that Apple uses to verify the eligibility of the iPhone for each firmware restoration. Without an SHSH, you cannot (no matter what you do, so stop asking about it) upgrade (i.e. from 4.1 to 4.3.3), restore (from 4.3.3 to 4.3.3) or downgrade (from 4.3.5 to 4.3.3) your iPhone firmware once Apple stops signing that particular versions of the firmware.

2. If you were lucky enough (or had the good foresight) to save the SHSH of your previous firmware versions, then you can follow the guide below on how to Upgrade/Restore/Downgrade to a firmware version that Apple no Longer Signs.

3. An iPhone 4 or a 3Gs with SHSH saved either using TinyUmbrella or iFaith. Members have reported success in downgrading from 5.1 to 5.0.1 on the iPhone 4 and the 3Gs using iFaith.

Guide on How to Downgrade from 5.1 to 5.0.1


The iPhone dev-team has released a new version of redsn0w that will allow you to downgrade your A5 devices from 5.1 to 5.0.1 thus enabling you to run absinthe for an untethered jailbreak. You still need to have 5.0.1 SHSH for this to work.

Please red the important notes in the link below

Redsn0w able to downgrade A5 devices from 5.1 to 5.0.1

The guides for windows can be found below

How to downgrade your iPhone 4S using redsn0w (Windows)

The guides for Mac can be found below

How to downgrade your iPhone 4S (Mac)

For A4 devices, you can follow the guide below

Downgrade iOS 5.1 To 5.0.1, 5.0, 4.3.3, 4.3.5 On iPhone, iPad, iPod touch [How-To Tutorial]


Guide on How to Downgrade from 5.1 to 4.x.x


How to Downgrade Your iPhone Firmware Using TinyUmbrella (Mac)

How to Downgrade Your iPhone Firmware Using TinyUmbrella (Windows)

Now, Apple has apparently stopped the process of unique SHSH identifier for iOS 5.0, they have made it more difficult. So if Apple were to come up with iOS 5.1 and stops signing 5.0.1, even if you have saved the SHSH for 5.0.1, the guide above will not work if you were to Restore/Downgrade /Upgrade to 5.0.1 if Apple stops signing that version.

There are steps apparently using iFaith with the saved SHSH + APTickets + Custom Firmware which supposedly will allow you to do it, but I've never tried it and Google is probably a better option in this case.

Apple has released iOS 5.1

DO NOT UPGRADE TO IOS 5.1 IF YOU WANT TO KEEP YOUR JAILBREAK

Yes. V4.

Congratez for the new V!

V3 has already past 2500 posts so it's time for a new version. My office has blocked any message boards and forum sites so have been using my iPhone to visit LYN so have not been able to create the new version. Will start cleaning up the 1st post with all the updated info soon.

Congratez bro azraeil...it V4 already...

Greeting to all sifus here.. I had just tried the SAM unlock solution on an iPhone 4 on iOS 5.0.1 with baseband 4.11.08 with DiGi and celcom SIM card. But both cant active at the end of the solution where it need u to use Itunes to active the phone. It keep showing that the sim was not supported.

My iPhone keeps rebooting. Anyone else face this issue?

Jailbroken iPhone 4 @ 5.0.1

Not sure if this helps but:

1. Try to re-JB
2. Hard reset
3. Restore and re-JB back

Hope this helps a little...

What was the original sim? You need to know exactly what the iPhone was locked to. AT&T or O2 or Vodafone.

congrats on the new thread.
hoping and waiting for the next jb =D

congrats bro azxraeil!

IClarified has come up with a video for the SAM unlock I will post the link into post #2 when I get home today.

Keep it goin bro, you've contribute a lot to this forum.
Thanks you.

guys,4s can jailbreak d ? only 5.0.1 ?
how about 5.0 ?

ps: no longer update with jailbreak thingy

5.0 4S can be jailbroken via absinthe and redsn0w (latest version)

5.1 cannot be jailbroken as yet

new home .. still waiting for 5.1 JB , lol

i search google,most of them only state 5.0.1
how bout 5.0 ? can jailbreak using the same method ?

This post has been edited by holoman: Apr 24 2012, 04:31 PM

Absinthe and redsn0w should be able to jailbreak 5.0 and 5.0.1

Since apple no longer signs 5.0.1, there is no way you can upgrade to 5.0.1

On another note, pod2g says that it will take him 1-2 months to release the 5.1 jailbreak. Darn.
