Download Redsnow 0.9.11b1 Now to Downgrade iOS of iPhone 4S, iPad 2/3

Published on May 11, 2012 by Richard Ker

This is probably the best redsn0w version yet as it allows you to downgrade iOS on iPhone 4S or iPad 2/3 without using iTunes.

By downgrading your iOS to an earlier version such as iOS 5.0.1, you can enjoy an untethered jailbreak on your iPhone or iPad once more!

Release notes by MuscleNerd and some warnings:

  • The new feature is at Extras->Even More->Restore
  • You cannot downgrade without the personalized SHSH blobs for your device at that lower firmware.  You need to have fetched those blobs while the signing window was open, using either Cydia’s built-in TSS@Home feature, or with TinyUmbrella.  The new Restore screen of redsn0w lets you choose either the remote blobs or local ones (for the earlier firmware).  If you don’t know where TinyUmbrella put your blobs, TinyUmbrella has a button that will show you (copy them out of that folder and feed them to redsn0w).
  • The A5 downgrade method actually updates to the latest firmware before downgrading to the earlier one.This process updates your baseband to whatever is newest.  DO NOT USE THIS METHOD IF YOU RELY ON UNOFFICIAL UNLOCKS of your iPhone4S.  Those who used the temporary SAM technique to unlock their iPhones to specific SIMs shouldn’t be affected by this baseband update.

This latest version of redsn0w is available for Mac and Windows.

iOS Downgrading Steps for iPhone 4S, iPad 2 or the new iPad (future):

Steps:

1. Start the new redsn0w 0.9.11b1 (Windows or Mac)

2. Connect your device and close iTunes if it launched itself automatically.

3. Go to Extras.

4. Click on Even More.

5. Click on Restore.

6. You will see IPSW, Local and Remote. Click on IPSW, and point redsn0w to the firmware file to which you want to downgrade to e.g. iOS 5.0.1. Redsn0w will now ask you for the stock iOS 5.1.1 firmware.

7. If you have your SHSH blobs saved:

  • Locally on your computer – click Local and find the .plist file that has the SHSH blobs for your device. Click Next.
  • Remotely on Cydia – redsn0w should automatically put your device into Recovery mode to fetch the files from Cydia server.

8. redsn0w will automatically stitch the SHSH blobs to the IPSW firmware file which you selected, and then it will automatically restore your device without having to launch iTunes.

Do note that this first release may contain some bugs so only use it if you’re desperate.

Unlock iPhone 4 and 3GS on iOS 5.1.1 with Ultrasn0w Fixer Patch [Old Basebands Only]

Published on May 10, 2012 by Richard Ker

Do you plan to update to iOS 5.1.1 but need to unlock your iPhone 4 or 3GS? Here’s the ultrasn0w fixer for iOS 5.1.1. Read below on how to install it.

UPDATE: Click here on how to officially unlock AT&T iPhone or click here for other worldwide network.

Important Notes:

1. Your iPhone 4 or iPhone 3GS running on iOS 5.1.1 must already be jailbroken with its baseband preserved. You can jailbreak it with the latest redsn0w (download it from the Dev Team’s blog) or build a custom firmware using the same tool.

2. Supported basebands are listed below. Everything else is NOT supported.

  • 01.59.00 (iPhone 4)
  • 04.26.08 (iPhone 3GS)
  • 05.11.07 (iPhone 3GS)
  • 05.12.01 (iPhone 3GS)
  • 05.13.04 (iPhone 3GS)
  • 06.15.00 (iPhone 3GS)

Installation Steps:

1. Download i-FunBox for Windows or DiskAid for Mac.

2. Launch i-FunBox or DiskAid and go to /private/var/root/Media.

3. Inside Media folder create a folder called Cydia.

4. Now inside Cydia folder create an AutoInstall folder. Note: The folder name is case-sensitive so be sure to name it accurately. It should look like the following:

/private/var/root/Media/Cydia/AutoInstall

5. Now copy ultrasnow.deb [ultrasn0w_1.2.5.deb] file, MobileSubstrate [mobilesubstrate_0.9.3997_iphoneos-arm.deb] file and ultrasn0w fixer patch into the AutoInstall folder.

6. Reboot iPhone (remember it’s currently boot tethered! So start redsn0w > Extras > Just Boot).

These fixes were made by unknown hackers; so in order to play safe, you can wait for the Dev Team to release the official ultrasn0w that’s compatible with iOS 5.1.1.

Apple Released iOS 5.1.1 with No Baseband Change; iPhone 4S’ Updated to 2.0.12

Published on May 8, 2012 by Richard Ker

What a surprise from Apple (as always) on a Monday! They’ve just released iOS 5.1.1 firmware for iPhone, iPad and iPod touch.

UPDATE: Unlock your AT&T iPhone permanently. Read more here.

Here are the change logs – iOS 5.1.1 improvements and bug fixes:

  • Improves the reliability of using HDR option for photos taken using the Lock Screen shortcut.
  • Addresses bugs that could prevent the new iPad from switching between 2G and 3G networks.
  • Fixes bugs that affected AirPlay video playback in some circumstances.
  • Improved reliability for syncing Safari bookmarks and Reading List.
  • Fixes an issue where ‘Unable to purchase’ alert could be displayed even after a successful purchase.
  • Patches important URL spoofing vulnerability in Safari
  • Baseband version for iPhone 4S (2.0.12), iPhone 4 (4.12.01), iPhone 3GS (5.16.05)

You should never install any new update if you rely on an unlock or untethered jailbreak, well not until proper tools or methods are available to unlock or jailbreak your iPhone.

MuscleNerd specifically warned A5 and A5x devices owners about updating to iOS 5.1.1, although hacker ion1c has already tweeted that the new iPad (3) has been successfully jailbroken.

Remember to save your SHSH as always!

Let’s hope the untethered jailbreak for iOS 5.1 and iOS 5.1.1 will be released soon!

AT&T Rejected Your Unlock Request with Their New Policies? Here’s How to Check

Published on May 6, 2012 by Richard Ker

Are you still trying to unlock your AT&T iPhone? AT&T has just updated their unlocking requirements and policy, probably due to serious abuse.

UPDATE: If you have an AT&T iPhone, you can officially unlock it using this. Need to check locked/unlocked status? See here.

AT&T announced early last month that they can provide free unlock subject to eligibility. They seemed to have revised their policies a few times and it becomes apparent that they now have become stricter. Thankfully, I managed to unlock mine without any hassle within 48 hours.

The following email was shared by one of our readers after his request was denied by AT&T:

AT&T will unlock an iPhone under the following circumstances:

• The person requesting the unlock is a current AT&T customer or a former AT&T customer who can provide the phone number or account number for their account.

• The iPhone was designed for use on AT&T’s network; all contract obligations, including any term commitment, associated with the device to be unlocked have been fully satisfied

• The iPhone has not been reported lost or stolen.

Also, current customer accounts must be in good standing with no past-due amount or unpaid balance and has been active for at least sixty (60) days. Former customer account may be eligible for unlocking so long as they owe AT&T no Early Termination Fee or other unpaid balance.

**AT&T will unlock an iPhone for an active and deployed member of the military who is a current AT&T customer in good standing and is able to provide AT&T with deployment verification; and for a person who purchased the iPhone from an authorized location at the ‘no commitment’ price and can provide proof of purchase.

Here’s another generic email reply by AT&T also shared by our readers:

Issue Tracking Number: CM20120418_xxxxxxxx

Dear Customer:

Thank you for your recent inquiry regarding your AT&T service. We apologize for any inconvenience this may have caused you. The issue has been resolved.

Should you have any further needs regarding this issue, please do not hesitate to call us at 1 800 331-0500 and reference the tracking number shown above.

Sincerely,
AT&T

Surprisingly, some of our readers are lucky enough and managed to get their iPhone fully unlocked even after receiving similar emails above.

If you currently have a baseband that can be unlocked with ultrasn0w or Gevey SIM, it’s still worth trying whether they actually did the unlock for you or not.

In this instance, you can test it by deactivating your iPhone and let Apple re-issue you a new activation ticket. Alternatively , you can also do a full restore but you must preserve your baseband just in case it was never unlocked by AT&T. You can do this by creating a custom firmware either with sn0wbreeze or redsn0w.

However, assuming that your iPhone is already jailbroken, you might want to avoid doing a full restore.

Follow the steps below:

1. Download the latest redsn0w from Dev Team’s blog.

2. Connect your iPhone to your computer and launch redsn0w.

3. Click on “Jailbreak” and you will see that your iPhone is connected in a “Normal” state but you need to put your iPhone in DFU mode.

4. Redsn0w will now detect build version of your iPhone.

5. After successful detection of your build, check “Deactivate” and uncheck all other  options (also uncheck Install Cydia).

6. Your iPhone will be deactivated. Remove your SIM and reboot your iPhone.

7. Connect it with iTunes and insert your SIM card. If all goes well you will see the following message on iTunes. Try with another SIM card to double check.

“CONGRATULATIONS, YOUR IPHONE HAS BEEN UNLOCKED!”

If it doesn’t activate, that means it’s still locked and you can try your luck again with AT&T. Repeat the steps above to re-activate your iPhone.

If AT&T rejected your request, you may want to use this service.

What is this iPhone Unlock Activation Ticket, Anyway?

Published on May 4, 2012 by Richard Ker

Many iPhone users have recently unlocked their iPhones using loktar_sun’s SAM unlock method. The unlock was done via Apple’s “activation ticket.” What is this activation ticket anyway? Read on…

UPDATE: Tired of jailbreaking and unlocking? Make your AT&T iPhone officially unlocked here or if yours is locked to other network, click here.

Activation is basically a process by which a new or recently restored iPhone can get by the “Emergency Call Screen” and it also enables your iPhone to connect to a cellular network.

The code or “ticket” that allows activation resides in the iOS lockdownd folder.

When you connect your iPhone after a full restore, iTunes generates an Activation Token and sends it to Apple’s activation server. Once the Activation Token is validated, the server will generate a WildcardTicket and signs it with Apple’s private key.

The WildcardTicket is then used for activating your iPhone’s baseband. It is stored in the file “/var/root/Library/Lockdown/activation_records/wildcard_record.plist”. It has all the information about SIM or network unlocks. Factory-unlocked iPhones receive a WildcardTicket that permits any SIM card.

Apple’s “Albert” servers handle all iDevice related activations which was recently patched by Apple to discontinue any “fake” activations via loktar_sun’s SAM unlock method.

The iPhone needs a cellular data connection for the first time, after the activation in iTunes. You can make calls if an alert says “iPhone is activated”.

Each ticket is unique to each SIM card and iPhone so this is the reason why you’re not able to use your saved activation ticket on multiple devices.

I hope that wasn’t too technical… but that’s basically how your iPhone gets unlocked. This ticket is valid for 3 years so it’s vital that you save it in case you need to do a full restore on your iPhone.
